  3. 3. PAIN• a feeling of distress, suffering or agony caused by the stimulation of specialized nerve endings• a blend of physiological and psychological experience of events occurring within the patients body which is always unpleasant and associated with the impression of damage to the tissues
  4. 4. PAIN• First symptom of injury;• Indicator of a disease process• The fifth vital sign
  5. 5. SOURCES OF PAIN STIMULINOCICEPTORS receptors that transmit pain sensation.NOCICEPTION physiologic processes related to pain perception.
  6. 6. PHYSIOLOGY OF PAINFOUR PHASES OF NOCICEPTION2. TRANSDUCTION Noxious stimuli (tissue injury) trigger the release of biochemical mediators (e.g., prostaglandins, bradykinin, serotonin, histamine, stubstance P) that sensitize nociceptors.
  7. 7. Noxious or painful stimulation also causes movement of ions across cell membranes, which excite nociceptors.Pain medication can work at this phase: by blocking production of prostaglandins (e.g., ibuprofen) or by decreasing the movement of ions across the cell membrane (e.g., local anesthetic)
  8. 8. 2. TRANSMISSION Neuronal action potential must be transmitted to & through the CNS before pain is perceived. Involves 3 segments before pain impulse is transmitted: 1st Segment – pain impulse travels from the peripheral nerve fiber to the spinal cord 2nd Segment – pain transmission from the spinal cord ascending to the brain via spinothalamic tracts to the brainstem and thalamus. 3rd Segment – transmission of signals between the thalamus to the somatic sensory cortex.
  9. 9. 2 Types of nociceptor fibers cause this transmission to the dorsal horn of the spinal cord: a. C fibers – large & myelinated; carry pain impulse at a rapid rate; throbbing, dull, aching pain. b. A-Delta fibers – small & unmyelinated; carry pain sensation at a slower rate; sharp, localized pain
  10. 10. Pain control can take place during this process: Opioid (narcotics) block the release of neurotransmitters, particularly substance P, which stops the pain at the spinal level.
  11. 11. Pain Threshold – the point at which a stimulus is perceived as pain.Pain Tolerance – amount of pain a person is willing to endure; only the person determines tolerance level.
  12. 12. 3. PERCEPTION When the client becomes conscious of pain.Pain perception occurs in the cortical structures, which allows for different cognitive-behavioral strategies to be applied to reduce the sensory & afferent components of pain.e.g., nonpharmacologic interventions such as distraction, guided imagery, & music can help direct the client’s attention away from the pain.
  13. 13. 4. MODULATIONDescribed as “descending system”Occurs when neurons in the brain stem send signals back down to the dorsal horn of the spinal cord.These descending fibers release substances such as endogenous opioids, serotonin, norepinephrine, which can inhibit the ascending noxious impulses in the dorsal horn.
  14. 14. PAIN MODULATIONENDOGENOUS OPIOIDS – pain inhibiting neurochemicals2. Enkephalins  Inhibits the release of substance P - a neurotransmitter that enhances transmission of pain impulses3. Endorphins  More potent than enkephalins4. Dynorphins  Have analgesic effect, which is 50% more potent than endorphins5. Neuromodulators  Modify pain (chemical regulators)
  16. 16. 1. SPECIFICITY THEORY There are specific nerve receptors for particular stimuli. e.g., Nociceptors – noxious stimuli (always interpreted as PAIN) Thermoreceptors – heat/cold Mechanoreceptors – pressure, pulling or tearing sensation Chemoreceptors – chemicals
  17. 17. PATTERN THEORYStates that pain is produced by intense stimulation on nonspecific fiber receptors, so any stimulus could be perceived as painful if the stimulation is intense enough.
  18. 18. GATE CONTROL THEORYStates that there is a “gate” in the spinal cord (substantia gelatinosa)When the gate is open, pain stimulus is transmitted thus pain is perceived.When the gate is closed, pain is blocked thus no pain is perceived. The gate is controlled by the balance impulse input from the small and large peripheral nerve fibers
  19. 19. TYPES OF PAIN
  20. 20. ACCORDING TO DURATION1. ACUTE PAIN• Temporary, immediate onset• Last for less than 6 months• Eventually subside after treatment or sometimes without treatmente.g., headache, postop pain, labor pain, toothache
  21. 21. 2. CHRONIC PAIN• Continuous, may begin gradually, persist or recur for an indefinite period of time, more difficult to manage effectively• (last 6 months or longer)
  22. 22. 3 TYPES of Chronic Pain:b.Chronic Nonmalignant Pain e.g., low back pain, Rheumatoid A.b. Chronic Intermittent Pain e.g., migraine headachec. Chronic Malignant Pain e.g., cancer
  23. 23. ACCORDING TO SOURCE/ORIGIN1. CUTANEOUS PAIN• Includes superficial somatic structures located in the skin & the subcutaneous tissues• “direct pain” since the pain accurately localizes the point of disturbance• e.g., finger cut, knot hair pulled out while combing, 1st degree burn
  24. 24. 2. DEEP SOMATIC PAIN• Includes bones, nerves, muscles & other tissues supporting these structures• Poorly localized; frequently radiates from primary site.• e.g., ankle sprain, jamming a knee
  25. 25. 3. VISCERAL PAIN• Includes all body organs located in a body cavity• Diffuse, poorly localized, vague, dull pain• e.g., obstructed bowel, cardiovascular disease
  26. 26. ACCORDING TO INTENSTIY1. MILD• One that is bearable usually tolerated by the client2. SEVERE• One which is intense & usually could not be tolerated by the client
  27. 27. ACCORDING TO LOCATION1. RADIATING PAIN• Perceived at the source of the pain & extends to nearby tissueCardiac pain – chest, left shoulder, down the arm2. REFERRED PAIN• Felt in an area distant from the site of the stimulusMI – left arm, shoulder, or jaw painCholecystitis – back pain & angle of scapula
  28. 28. 3. INTRACTABLE PAIN• Pain that is highly resistant to relief• Advanced Malignancy4. NEUROPATHIC PAIN• Result of current or past damage to the peripheral or CNS & may not have a stimulus, such as tissue or nerve damage.• Nerve injury that serves the hand would be perceived a pain-hand even though the injury may be at the spinal cord level.
  29. 29. 5. PHANTOM PAIN• Painful sensation perceived in a body part that is missing
  30. 30. FACTORS AFFECTING PAIN PERCEPTION AND RESPONSE1. ETHNIC & CULTURAL VALUES• Filipinos are known to be sufferers who consider pain as sacrifice for sins committed.• Voicing pain – appropriate Italians inappropriate Germans (stoicism)• Mexicans/arabs – moaning/crying use to alleviate pain rather than need for intervention
  31. 31. 2.DEVELOPMENTAL STAGES• Infants - sensitivity• Toddlers – cry & anger - threat to security & punishment• School-age – not cry or express much pain so that parents will not get angry• Adolescent – not report pain weakness• Adults – not report pain indicates poor diagnosis, weakness, failure
  32. 32. 3. ENVIRONMENT & SUPPORT PEOPLE• Hospital environment can be associated with pain; Places that are noisy & have glaring lights can compound pain sensation4. POST PAIN EXPERIENCES• A person who has witnessed a family member who experienced severe pain may have difficulty enduring the same experience once it arises
  33. 33. 5. MEANING OF PAIN• A woman giving birth may tolerate pain infavor of a desired baby• An athlete who undergone knee surgery to prolong his career may tolerate pain better than one who was shot by an enemy6. ANXIETY & STRESS• A person who suffers fatigue may not have a good coping with pain
  34. 34. PAIN ASSESSMENT TOOLSOnsetLocationDurationCharacteristicsAggravating factorsRadiationTreatment
  36. 36. MISCONCEPTION & MYTHS OF PAIN• Myth: Addiction occurs with prolonged use of Morphine and Morphine derivatives• FACT: THE INCIDENCE OF ADDICTION IS LESS THAN 0.1%
  37. 37. • Myth: The nurse or the physician is the best judge of a clients pain.• FACT: ONLY THE CLIENT CAN JUDGE THE LEVEL & DISTRESS OF THE PAIN, THATS WHY CLIENTS SHOULD BE INCLUDED IN PAIN MANAGEMENT.
  39. 39. • Myth: It is better to wait until a client has pain before giving medication.• FACT: IT IS BETTER TO ROUTINELY ADMINISTER ANALGESIA TO MAINTAIN LOW LEVEL OF PAIN THAN TO “CATCH-UP” ONCE PAIN ARISES.
  40. 40. • Myth: Real pain has an identifiable cause.• FACT: THERE ARE ALWAYS CAUSES OF PAIN BUT SOME MAY BE VERY OBSCURE.
  41. 41. • Myth: The same physical stimulus produces the same pain intensity, duration and distress in the same people.• FACT: INTENSITY, DURATION, AND DISTRESS VARY WITH EACH INDIVIDUAL
  42. 42. • Myth: Some clients lie about the existence or severity of their pain.• FACT: VERY FEW PEOPLE LIE ABOUT THEIR PAIN
  43. 43. • Myth: Very young or very old people do no have as much pain.• FACT: ALL CLIENTS WITH INTACT NEUROLOGIC SYSTEM EXPERIENCE PAIN. AGE IS NO A DETERMINANT OF PAIN EXPERIENCE.
  46. 46. • Myth: If the pain is relieved by non- pharmaceutical pain relief techniques, the pain was not real anyway.• FACT: NON-PHARMACEUTICAL METHODS CAN BE EFFECTIVE IN RELIEVING PAIN.
  47. 47. ASSESSMENT• Ask the client about the pain and to describe it in terms of degree, quality, area, and frequency• Observable indicators of pain include: moaning; crying; irritability; restlessness; grimacing or frowning; inability to sleep, rigid posture; increased blood pressure, heart rates, or respirations; nausea; and diaphoresis• Ask the client to use a number-based pain scale (a picture-based scale may be used in children) to rate the degree of pain
  48. 48. PAIN MANAGEMENT Refers to the techniques usedto prevent, reduce, relieve pain.
  49. 49. A. NON-PHARMACOLOGIC PAIN MANAGEMENT1. PHYSICAL INTERVENTION  Includes providing comfort, altering physiologic responses & reducing fears associated with pain-related immobility or activity restriction. c. CUTANEOUS STIMULATION  Redirects the client’s attention to the tactile stimuli away from the pain stimuli; It releases endorphins; it stimulates large diameter A- beta sensory nerve fibers.
  50. 50. • MASSAGE  back rub to reduce pain; stimulate client’s skin by lightly kneading, pulling or pressing with fingers, palms or knuckles.o ACCUPRESSURE  Application of pressure to areas or points used in acupuncture known as Meridianso CONTRALATERAL STIMULATION  Stimulating the skin opposite to the painful area.
  51. 51. o HEAT & COLD APPLICATION  The application of heat and cold or the alternate application can soothe pain resulting from muscle strain  Heat applications may include warm- water compresses, warm blankets, Aquathermia pads, and tub and whirlpool baths; may require a physician’s order
  52. 52. b. IMMOBILIZATION Restricting movement of body part may help manage episodes of acute pain e.g., Splint holds joints or fractured bones that maybe painful once moved
  53. 53. C. TRANSCUTANEOUS ELECTRICALNERVE STIMULATION (TENS)  (portable, battery operated device) is a method of applying low voltage electrical stimulation directly over identified pain areas. C/I in clients with pacemakers, arrhythmias or in areas of skin breakdown.
  54. 54. D. ACCUPUNCTURE  very thin metal needles are skillfully inserted into the body @ designated locations & @ various depths & angles Meridians – accupuncture points distributed patterns disease interrupts energy flow in the body and insertion of needles at specific points will re establish healthy energy flow.
  55. 55. Acupuncture Acupuncture is a traditional Chinese medicine that stimulates specific points in the body in order to restore a proper balance of various chemicals. Some people who suffer from chronic pain find thatacupuncture provides a measure of pain relief where all other methods fail. The way acupuncture suppresses pain remains a mystery. Somescientists now believe that it triggers the release of pain-relieving body chemicals called endorphins and enkephalins. Others argue that acupuncture’s pain-relieving effects are brought about by a patient’s
  56. 56. 2. MIND-BODY INTERVENTION (Cognitive-Behavioral)A. DISTRACTION  Directs away the attention of the client from the painful sensation or the negative emotional arousal associated with pain TYPES OF DISTRACTION: 1. Visual Distraction – read or watch tv 2. Auditory Distraction – humor, listen to music
  57. 57. MUSIC  Physiologic mechanism has not been established in the use of music to relieve pain but possible theories include distraction, release of endogenous opioids, & dissociationHUMOR  Believed to help increased the production of endogenous opioids endorphines, which are natural pain killers.
  58. 58. 3.Tactile Distraction – massage, slow rhythmic breathing 4. Intellectual Distraction – card games, crossword puzzleB. RELAXATION TECHNIQUES Gradually tighten then deeply relax various muscle groups proceeding systematically from one area to the next Reduce muscle tension & anxiety
  59. 59. C. IMAGERY  Help client visualize a pleasant experience  Help distract themselves from their pain which may increase pain tolerance; produce relaxation response; diminished the source of pain (e.g.tension headache) D. MEDITATION  Client sits comfortably & quietly with focused attention away from pain E.g., flow of the breath; picture image of great spiritual being or peaceful place
  60. 60. E. BIOFEEDBACKBiofeedback in ProgressA patient at a biofeedback clinic sits connected to electrodes on hishead and finger. Biofeedback is a technique in which patients attempt tobecome aware of and then alter bodily functions such as muscle tensionand blood pressure. It is used in treating pain and stress-relatedconditions, and may help some paralyzed patient use of their limbs.
  61. 61. Biofeedback in ProgressA patient at a biofeedback clinic sits connected to electrodes on hishead and finger. Biofeedback is a technique in which patients attempt tobecome aware of and then alter bodily functions such as muscle tensionand blood pressure. It is used in treating pain and stress-relatedconditions, and may help some paralyzed patient use of their limbs.
  62. 62. F. HYPNOSIS Hypnotic state; suggest to alter character of pain or one’s attitude toward itG. THERAPEUTIC TOUCH use hands to rearrange energy field to normalH. MAGNETS Believed that the pull of magnet increased blood flow to the region of pain, opening the NaCl channels in the cell.
  64. 64. 1. OPIOID ANALGESICS (NARCOTIC) Derived from natural opium alkaloids & their synthetic derivatives Suppress pain impulses but can suppress respiration and coughing by acting on the respiratory and cough center in the medulla of the brain stem Can produce euphoria and sedation Can cause physical dependence
  65. 65. PHYSICAL DEPENDENCE  means that a person experiences physical discomfort, known as withdrawal syndrome, when a drug that client has taken routinely for some time is abruptly discontinued.  to avoid withdrawal symptoms, drugs that are known to cause physical dependence are discontinued gradually. Dosage or frequency of adm. is lowered over 1 week or longer.
  66. 66. NARCOTIC ANALGESICS MEPERIDINE HYDROCHLORIDE (Demerol) Can cause respiratory depression, tachycardia, constipation, urine retention, hypotention, and dizziness• Used for acute pain and as a preoperative medication• Contraindicated in head injuries and in the presence of increased intracranial pressure, respiratory disorders, hypotentions, shock and severe hepatic or renal didsease,
  67. 67. • Should not be taken with alcohol or sedative hypnotics; may increase CNS depression• To administer intravenously, dilute in at least 5 ml of sterile water or NSS for injection, then administer dose over 4 to 5 minutes CODEIN SULFATE• Also used in low doses as a cough suppressant• Can cause constipation
  68. 68.  MORPHINE SULFATE• Can cause respiratory depression, postural (orthostatic) hypotention, urine retention, constipation, and papillary constriction• May cause nausea and vomiting because of increased vestibular sensitivity• Used to ease acute pain resulting from myocardial infarction or cancer, for dyspnea resulting from pulmonary edema, and as a preoperative medication
  69. 69. • Monitor intake and output and assess client for urine retention• Instruct client to avoid activities that require alertness• Have a narcotic antagonist available (e.g., Naloxone (Narcan), oxygen, and resuscitation equipment available
  70. 70. NARCOTIC ANTAGONISTSDescription• Use to treat respiratory depression from narcotic overdose - Naloxone (Narcan)Interventions• Monitor BP, pulse, & RR q 5 mins. initially, tapering to q 15 minutes, & then q 30 mins. until the client’s condition is stable• Attach a cardiac monitor to the client & observe cardiac rhythm
  71. 71. • Auscultate breath sounds• Have resuscitation equipment available• Do not leave client unattended• Monitor client closely for several hours; when the effects of the antagonist wears off,• the client may again display signs of narcotic overdose
  72. 72. 3 Primary Types of Opioids:1. FULL AGONISTS  pure opiod drugs producing maximum pain inhibition, an agonists effect.  No ceiling on the level of analgesia  Dose can be steadily increased to relieve pain  No maximum daily dose limit  Demerol, Morphine, Codeine
  73. 73. 2. MIXED AGONISTS-ANTAGONIST can act like opioids & relieve pain (agonist effect) when given to client who has not taken any pure opioids. block or inactivate other opioid analgesics when given to client who has been taking pure opioids (antagonist effect) have ceiling dose & not recommended for use w/ terminally ill clients. Nubain, Stadol
  74. 74. 3. PARTIAL AGONISTS have ceiling effect in contrast to a full agonist. Buprenorphine (Buprenex)Pentazocine (Talwin)
  75. 75. 2. NON-OPIOID ANALGESICS They relieve pain by acting on peripheral nerve endings at the injury site& decreasing the level of inflammatory mediators & interfering with the production of prostaglandins at the site of injury.
  76. 76. ACETAMINOPHEN (TYLENOL)Description• Inhibits prostaglandin synthesis• Used to decreased pain and feverContraindications• Hepatic or renal disease, alcoholism, and hypersensitivitySide Effects• Major concern is hepatotoxicity
  77. 77. NSAIDs and ACETYLSALICILIC ACID (Aspirin)• NSAIDs are aspirin and aspirin-like medications that inhibit the synthesis of prostaglandins• Act as analgesics to relieve pain, as antipyretics to reduce body temperature, and as anticoagulants to inhibit platelet aggregation• Used to relieve inflammation and pain and to treat rheumatoid arthritis, bursitis, tendonitis, osteoarthritis, and acute gout
  78. 78. 3. ADJUVANT ANALGESICSIs a medication that was developed for other than analgesia but has been found to reduce chronic pain & sometimes acute pain, in addition to its primary action.  Muscle Relaxant – muscle spasm Anticonvulsants – nerve injury Corticosteroids – reduce inflammation & edema
  80. 80. SURGERYas a science and an art surgery is the branch of medicine that comprises perioperative patient care encompassing such activities as pre- operative preparation, intra-operative judgement, and post-operative care of patients.
  81. 81. CATEGORIES & PURPOSES OF SURGERYACCORDING TO PURPOSE1. Diagnostic  Performed to determine the origin & cause of a disorder or the cell type for cancer  breast biopsy2. Exploratory  Estimation of the extent of disease or confirmation of a diagnosis  exploratory laparotomy, pelvic laparotomy
  82. 82. 3. Curative  Performed to resolve a health problem by repairing or removing the cause  Classification: – Ablative Includes removal of an organ; e.g., appendECTOMY (suffix)
  83. 83. b.Constructive Involves the repair of congenitally damaged organ e.g., cheiloPLASTY, orchidoPEXYc.Reconstructive Involves repair of damaged organ e.g., Total joint replacement
  84. 84. 4. Palliative  Performed to relieve symptoms of a disease process, but does not cure  Nerve root resection, Colostomy5. Cosmetic  Performed primarily to alter or enhance personal appearance  Rhinoplasty, Blepharoplasty
  85. 85. ACCORDING TO URGENCY1. Emergent  condition is life-threatening that requires surgery at once  e.g., gunshot or stab wound, severe bleeding2. Urgent  performed as soon as client is stable & infection is under control; life threatening if treatment is delayed more than 24-48H  e.g., appendectomy, intestinal obstruction
  86. 86. 3. Required  Client should have surgery; planned for a few weeks or months  e.g., Prostatic hyperplasia w/o obstruction, Cataracts, Simple Hernia4. Elective  Client will not be harmed if surgery is not performed but will benefit if it is performed  e.g., Revision of Scars, Vaginal Repair
  87. 87. 5. Optional  Personal preference usually for aesthetic purposes  e.g., Cosmetic surgery
  88. 88. ACCORDING TO DEGREE OF RISK3.Minor  Procedure of less risk; generally not prolonged; leads to few complications2. Major  Procedure of greater risk; usually longer & more extensive; great risk of complications
  89. 89. ACCORDING TO EXTENT OF SURGERY2. Simple  Only the most overtly affected areas involved in the surgery  e.g., Simple or Partial Mastectomy3. Radical  Extensive surgery beyond the area obviously involved  e.g., Radical Mastectomy, Radical Hysterectomy
  90. 90. SURGICAL SETTING1. INPATIENT  Refers to client who is admitted to a hospital  Admitted on the day of surgery (Same-day Admission – SDA)2. OUTPATIENT & AMBULATORY  Refers to a client who goes to the surgical area the day of the surgery & returns home on the same day (Same-day Surgery – SDS)
  92. 92. PERIOPERATIVE NURSINGAssist clients and their significant others through the surgical episode,o help promote positive outcomes, and to help clients achieve their optimal level of function and wellness after surgery.Emphasis on safety & client educationUse Knowledge, judgement & skills
  93. 93. PREOPERATIVE PERIODBegins when the client is scheduled forsurgery & ends at the time of transfer to surgical suite
  94. 94. PREOPERATIVE PERIOD Focuses on client’s readiness – client education & any intervention: 1. Reduce anxiety 2. Reduce complication 3. Promote cooperation Needed before surgery to: 1. Validate & clarify information client received from surgeon or members of health team 2. Identify problems that warrant further assessment &/or intervention before surgery
  95. 95. PREOPERATIVE ASSESSMENTA. MEDICAL/HEALTH HISTORY  Purpose of reviewing medical history is to determine operative risk.
  96. 96. COLLECT THE FOLLOWING DATA:1. AGE Older – risk of complication; immune system functioning; delays wound healing; frequency of chronic illness; alter operative response/risk2. DRUGS & SUBSTANCE USE o Tobacco - risk of pulmonary complications (changes in lungs & cavity) o Alcohol & illicit subs. – alter response to anesthesia & pain meds. withdrawal before surgery may lead to delirium tremens
  97. 97. o PRESCRIPTION & OVER THE COUNTER – affect how client reacts to operative experienceo Potential effects for reaction or serious adverse effect with some herbs & specific drugs.3. MEDICAL HISTORYo Chronic illness increased surgical risk
  98. 98. 4. CARDIAC HISTORY o Complications from anesthesia occur often o Impair ability to withstand hemodynamic changes & alter response to anesthesia o Risk for MI during surgery higher with pre-existing cardiac problem
  99. 99. 5. PULMONARY HISTORY o Smoker/Chronic Respiratory Problem - chest rigidity & loss of lung elasticity reduce anesthesia excretion. o Smoking - blood level of Carboxyhemoglobin which decreases O2 delivery to organs acts on cilia of pulmonary mucous membrane which lead to retain secretion & predisposes clients to pneumonia & atelectasis (reduce gas exchange & causes intolerance of anesthesia)
  100. 100. Chronic lung problems (asthma, emhysema, chronic bronchitis) reduce lung elasticity reduce gas exchange reduce tissue oxygenation7. ANESTHESIA o Affect readiness for surgery o those w/ complication - fear & concerns of scheduled surgery
  101. 101. 8. DISCHARGE PLANNING o Assess client’s home, environment, self- care capabilities, support system, & anticipate post-op needs before surgery Older clients & dependent adult need transport referrals Home care nurse/health center nurse need to monitor recovery & provide instruction
  102. 102. B. PHYSICAL ASSESSMENTTo obtain baseline dataComplete set V/S – abnormal V/S may postpone surgery until problem is treated & condition is stable
  103. 103. 1. CARDIOVASCULAR SYSTEMCardiac problems – 30% of surgery-related deathsHPN – common & often undiagnosed affect response to surgery Assess cardiac sounds for rate, regularity & abnormalities Hands & feet – for temp, color, peripheral pulses, capillary refill, & edemaREPORT: absent peripheral pulses, pitting edema, cardiac symptoms ( chest pain, dyspnea) for further assessment & evaluation
  104. 104. 2. RESPIRATORY SYSTEMAge, smoking history (second handsmoke), chronic illnessOverall posture, RR, rhythm & depth, overall respiratory effort & lung expansionDocument clubbing of fingertips ( swelling base nailbeds caused by chronic lack of O2) or cyanosis
  105. 105. 3. RENAL/URINARY SYSTEMKidney function – affects excretion of drugs & waste products including ANESTHETIC & ANALGESIC AGENTSRenal function reduced (Older client) – fluid & electrolyte balance can be altered
  106. 106. KIDNEY IMPAIRED: excretion of drugs & anesthetic agent Drug effectiveness may be altered Buscopan, Morphine, Demerol, Barbiturates causes confusion, disorientation, apprehension, restlessness with kidney function
  107. 107. 4. NEUROLOGIC SYSTEMAssess overall mental status – LOC, orientation, ability to follow commands) before planning preoperative teaching & careAssess motor & sensory deficits – problems may affect type of care needed during surgical experienceRisk for falling (esp older) – evaluate mental status, muscle strength, steadiness of gait, sense of independence, ability to ambulate
  108. 108. 5. MUSKULOSKELETAL SYSTEM Problems may interfere with positions during & after surgery. e.g., w/ Arthritis – may be able to assume surgical position but have discomfort after surgery from prolonged joint immobilization History joint replacement & document exact location of prosthesis – ensure that electrocautery pads are not place ON or NEAR area of prosthesis – cause electrical burn
  109. 109. 6. NUTRITIONAL STATUSMalnutrition & Obesity - surgical risk metabolic rate & depletes K, Vit C & B – needed for wound healing & blood clottingMalnourished - S. CHON slows recovery & negative nitrogen balance may result from depleted CHON store - risk delayed wound healing, possible dehiscence & evisceration, dehydration & sepsis
  110. 110. OBESE CLIENT – often malnourished because of imbalance diet  risk poor wound healing – excessive adipose (fatty) tissue few blood vessels, little collagen, nutrients needed for wound healing Stresses heart & reduces lung volume – affects surgery & recovery Need large doses of drugs & may retain them longer after surgery
  111. 111. 7. PSYCHOSOCIAL ASSESSMENTTo determine level of anxiety, coping ability, & support system– provide information & offer support as neededDegree of Anxiety & Fears varies according: Type of surgery Perceived effects of surgery & potential outcome Client’s personalitySURGICAL THREAT – life, body image, self- esteem, self-concept, or lifestyle
  112. 112. FEAR of death, pain, helplessness, socio- economic status, dx of life-threatening conditions, possible disabling/crippling effects or unknownANXIETY & FEAR affect client’s ability to learn Cope & cooperate w/ teaching & operative procedures May influence amount & type anesthesia needed & may slow recovery
  113. 113. 8. LABORATORY ASSESSMENT Provide baseline data about health & help predict potential complications OUTPATIENT – PAT (preadmission testing) 24-28 days before surgery valid unless there’s change in condition or taking drugs that can alter lab values ( Warfarin, Aspirin, Diuretics) COMMON: Urinalysis, Blood type, crossmatching, CBC, Hgb, Hct, Clotting studies (PT, platelet count), electrolyte levels, s. creatinine
  114. 114.  Urinalysis – assess abnormal subs.- CHON, glucose, blood, bacteria Report Electrolyte imbalance to surgeon & anesthesiologist before surgery ♠ K - risk toxicity if taking digoxin - slow recovery from anesthesia - cardiac irritability ♠ K - risk dysrhythmias esp. w/ use of anesthesia K must be corrected before surgery Baseline ABG – w/ chronic pulmonary problem
  115. 115. 9. RADIOGRAPHIC ASSESSMENTCHEST XRAY – often young healthy adults not required Determine size & shape of heart, lungs, & major vessels Determine presence of pneumonia or TB Provides baseline data in care of complication Results assist anesthesiologist in selecting anesthesia for emergency surgery
  116. 116.  Abnormal findings alert for potential cardiac or pulmonary complication Cardiac failure, cardiomyopathy, pneumonia or infiltrates may cause cancellation or delay of elective surgeryCT SCAN OR MRI
  117. 117. Electrocardiogram (ECG)• Common non-invasive diagnostic test that aids evaluation of heart function by recording electrical activity• Abnormal findings alert for potential cardiac or pulmonary complication
  118. 118. Preoperative Care
  119. 119. Obtaining Informed Consent• The surgeon is responsible for obtaining the client’s consent for surgery• Ensure that informed consent has been signed and that any additional necessary consents (e.g., limb disposal) have been obtained & you serve as a WITNESS to the signature, not to the fact that the client is informed• Sedation should not be administered to the client before he or she signs the consent
  120. 120. Nurse: Not responsible for providing detailed information about the surgical procedure ROLE: to clarify facts that have been presented by the physician & dispel myths that the client or family may have about the surgical procedure
  121. 121. • The patient should personally sign the consent unless she/he:• MINOR – A PARENT OR LEGAL GUARDIAN• EMANCIPATED MINOR (married or independently earning a living – he/she may sign A MINOR WHO HIS THE PARENT OF AN INFANT OR CHILD WHO IS HAVING A PROCEDURE - he or she may sign for his/her child ILLITERATE- HE/SHE MAY SIGN WITH AN “X”, AFTER WHICH THE WITNESS WRITE “PATIENT MARK”
  122. 122. CANNOT WRITE: Sign w/ an X with 2 witnessess Emergency: Phone or telegram authorization but follow-up with written consent ASAP Lifethreatening: With effort to contact person w/ medical power of atty., consent is desired but not essential Written consultation by 2 physician not assoc. w/ the case ( formal consultation legally supports decision for surgery until appropriate person signs the consent)
  123. 123. No family: Courts appoints legal guardianBlind: May sign his own consent with 2 witnessessOther language: Translator and a 2nd witness A WITNESS VERIFIES THAT THE CONSENT WAS SIGNED WITHOUT COERCION AFTER THE SURGEON EXPLAINED THE DETAILS OF THE PROCEDURE ( physician, nurse, facility employee, family members (as established by policy)
  124. 124. Advance DirectiveProvides legal instruction to healthcare providers about the client’s wishes & are to be followed.Encompasses durable power of attorney and living willLiving will or durable power of attorney as mandated by The Patient self- determination act. (USA)
  125. 125. Nutrition• Assess the surgeons orders regarding the intake of food and fluids before surgery and for the administration of intravenous fluids• NPO - NO eating, drinking & smoking (nicotine stimulates gastric secretion) for 8 hours before the surgical procedure – to decrease risk of aspiration• Fasting > 8H – possible fluid & electrolyte imbalance & blood glucose levels• Emphasize the IMPORTANCE OF ADHERENCE - failure result in cancellation or increase risk of aspiration during surgery
  126. 126. Elimination• If the client is to undergo intestinal or abdominal surgery, an enema, a laxative, or both may be prescribed for the night before surgery – to prevent injury to colon & reduce number of intestinal bacteria• The client should void immediately before surgery• FC is in place, it should be emptied immediately before surgery & the amount & quality of UO documented
  127. 127. Surgical Site• Prepare to clean the surgical site with a mild antiseptic soap the night before surgery, as prescribed• – reduces contamination & no. of organism @ site• Hair should be shaved only if it will interfere with the surgical procedure and only if prescribed• Skin prep is the first step in prevention of surgical wound infection.
  128. 128. Medications• Note medications client is taking, including herbal products; some medications (e.g., antihypertensives and antidysrhythmics) can interact with anesthetic agents• Check with the surgeon regarding administration of prescribed medications; some medications (e.g., cardiac medications) may be administered with a sip of water• If the client has diabetes mellitus, check with the surgeon regarding administration of an oral hypoglycemic or insulin
  129. 129. Preoperative Teaching• Reduce apprehension and fear• Increased cooperation & participation in care after surgery• Decrease complications
  130. 130. Client Teaching• Describe what client should expect after surgery• Instruct client to notify nurse of pain after surgery and reassure client that pain medication will be prescribed, to be given as the client requests• Instruct client not to smoke for at least 24 hours before surgery• Instruct client in deep-breathing and coughing techniques, the use of incentive spirometry and its importance
  131. 131. Incentive Spirometer – promote complete lung expansion & prevent pulmonary problems
  132. 132. Chest Physiotherapy
  133. 133. Chest Physiotherapy Percussion and vibration over the thorax to loosen secretions in the affected area of the lungsContraindications• When bronchospasm occurs by its use stop the procedure • Rib fracture• History of pathological fractures • Chest incisions
  134. 134. LEG AND FOOT EXERCISES• Instruct client in leg and foot exercises to prevent venous stasis of blood and facilitate venous blood return [Figure]
  135. 135. • SplintingProvide support, promotes a feeling of security, & reduces pain during coughing • CoughingMay be performed along with deep breathing q 1-2H after surgeryTo expel secretions, keep lungs clear, allow full aeration, prevent pneumonia & atelectasis“Do Not Cough” – hernia repair
  136. 136. • Inform client of any invasive devices that may be needed after surgery (e.g., nasogastric tube, drain, Foley catheter, epidural catheter, intravenous or subclavian line)• Instruct client not to pull on invasive devices and reassure client that they will be removed as soon as possible
  137. 137. • Early Ambulation Stimulates intestinal motility, enhance lung expansion, mobilizes secretion, promotes venous return, prevents joint rigidity, relieves pressure• ROME – prevent joint rigidity & muscle contracture
  138. 138. Psychosocial Preparation• Assess clients anxiety level• Address clients questions and concerns regarding surgery• Give client privacy to prepare psychologically for surgery
  139. 139. Preoperative Checklist• Review checklist to ensure that each item is addressed before client is transported to surgery• Ensure that client is wearing an identification bracelet• Assess client for allergies• Ensure that prescribed laboratory-test results and electrocardiography and chest- radiography reports are documented in the clients record
  140. 140. • Remove clients jewelry, makeup, dentures, hairpins, nail polish, glasses, and prostheses as appropriate• Document that valuables have been given to clients family members or locked in the hospital safe• Monitor and document clients vital signs
  141. 141. 3. Prosthesis or Dentures- should be removed to prevent obstruction in the airway
  142. 142. 2. GIT /Elimination- insertion of indwelling catheter (foleycatheter), administration of cleansing enema- this is to ensure thatneither of the bladder, nor the bowel is distended during surgery- nutrition/ hydration-- NPO 8 hours before surgery, but some institution may allow clearliquids 3-4 hours before-- IVF infusion may be started to ensure adequate hydration
  143. 143. Pre operative medicationsAnticholinergics - Atropine SO4, Scopolamine Glycopyrrolate - control secretions• Antiemetics - Dropiridol, Thorazine - prevents vomiting• Tranquilizers- Diazepam, Lorazepam - decrease anxiety• - Sedatives- Medazolam, Phenobarbital - induce sleep and decrease anxiety• Opioids- Morphine SO4, Meperidine Hcl - relieve pain, decrease anxiety
  144. 144. • Tell the client that he or she will feel drowsy shortly after the medications are administered• After administering the preoperative medications, keep the client in bed with the side rails up and place the call bell next to the client• Instruct the client not to get out of bed and to call for assistance if needed
  145. 145. Transporting the client to the operating room• Per stretcher – enough help for safety• Cover with blanket – protect from drafts• Place side rails and restraint above knee• Record accompanies client• Smooth as possible – sedated- to prevent nausea vomiting• Avoid rapid walking or swinging around corners• Prepare room for post operative care
  146. 146. Arrival in the Operating Room• When the client arrives in the operating room, the operating-room nurse will check the identification bracelet against the clients verbal response• The clients chart will be checked for completeness and reviewed for informed consent• The surgeons orders will be reviewed to ensure that they were carried out
  147. 147. INTRAOPERATIVE PERIODbegins when the client is transferred tothe operating room bed and ends whenthe client is transferred to an area forrecovery from anaesthesia
  148. 148. Key words of OR practiced are: 1. Caring 3. Discipline 2. Conscience 4. Technique Optimal client care requires an inherent surgical conscience, self-discipline & the application of principles of aseptic & sterile techniqueSURGICAL CONSCIENCE – “Surgical Golden Rule”“Do unto the patient as you would have others do unto you.”
  149. 149. Surgical Conscience One’s inner voice for the conscientious practice of asepsis & sterile technique @ all times. Conscience dictates that appropriate action to be taken, whether the person is with others or alone & unobserved Foundation for the practice of strict aseptic & sterile technique
  150. 150. ASEPTIC TECHNIQUE– to maintain asepsis (absence of microorganism that caused diseased) STERILE TECHNIQUE Method by which contamination which microorganism is prevented to maintain sterility throughout the operative procedure. Is the responsibility of everyone caring for the client in the OR.
  151. 151. PRINCIPLES OF STERILE TECHNIQUE ARE APPLIED:1. In preparation for operation by sterilization of necessary materials & supplies2. In preparation of operating team to handle sterile supplies & intimately contact wound3. In maintenance of sterility & asepsis throughout operative procedure4. In terminal sterilization & disinfection at conclusion of operation
  152. 152. PRINCIPLES OF STERILE TECHNIQUE1. ONLY STERILE ITEMS ARE USED WITHIN STERILE FIELD If you are in doubt about the sterility of anything, consider it not sterile.c. If sterilized package is found in a nonsterile workroom.d. If uncertain about actual timing or operation of sterilizer. Items processed in a suspect load are considered unsterile.e. If unsterile person comes into close contact with a sterile table & vice versa.
  153. 153. d. If sterile table or unwrapped sterile items are not under constant observation.a. If sterile package wrapped in material other than plastic or moisture-resistant barrier becomes damp or wet. Humidity in storage area or moisture on hand may seep into package.b. If the integrity of the packaging material is not intact.c. If sterile package wrapped in a pervious muslin or other woven material drops to the floor or other area of questionable cleanliness. These material allow implosion of air into package. A dropped package is considered contaminated.
  154. 154. If the wrapper is impervious & the area of contact is dry, the item may be transferred to the sterile field. Packages that have been dropped on the floor should not be put back into sterile storage.2. GOWNS ARE CONSIDERED STERILE ONLY INFRONT FROM CHEST TO LEVEL OF STERILE FIELD & THE SLEEVES FROM ABOVE ELBOWS TO CUFFa. Self-gowning & gloving should be done from a sterile surface for this purpose only to avoid dripping water onto sterile supplies or sterile field.
  155. 155. b. Stockinet cuffs of gown are enclosed beneath sterile gloves. Stockinet is absorbent & will retain moisture, thus this part of gown does not provide a microbial barrier.c. Sterile persons keep hands in sight @ all times & at or above level of waist or sterile field.d. Hands are kept away from face. Elbows are kept close to sides. Hands are never folded under arms because of perspiration in axillary region. Neckline, shoulders, & back also may become contaminated with perspiration.
  156. 156. e. Sterile persons are aware of height of team members in relation to each & the sterile field. Changing levels @ sterile field is avoided. Gown is considered sterile only down to highest level of sterile tables. If a sterile person must stand on a platform to reach operative field, platform should be positioned before this person steps up to draped area. Sterile person should sit only when entire procedure will be performed @ this level.
  157. 157. 3. TABLES ARE STERILE ONLY AT TABLE LEVEL a. Only top of a sterile draped table considered sterile. Edges & sides of drapes extending below table level are considered unsterile. b. Anything falling or extending over table edge, such as a piece of suture, is unsterile. Scrub person does not touch part hanging below table level. c. If unfolding a sterile drape, the part that drops below table surface is not brought back up to table level. Once placed, draped is not moved or shifted. d. Cords, tubings, etc., are secured on the sterile field with a non-perforating device to prevent them from sliding over the table edge.
  158. 158. 4. PERSON WHO ARE STERILE TOUCH ONLYSTERILE ITEMS OR AREAS; PERSONS WHO ARENOT STERILE TOUCH ONLY UNSTERILE ITEMSa. Sterile team members maintain contact with sterile field by means of sterile gowns & gloves.b. Non-sterile circulating nurse does not directly contact the sterile field.c. Supplies are brought to sterile team members by the circulating nurse who opens the wrappers on sterile packages. The circulating nurse ensures sterile transfer to the sterile field. Only sterile items touch sterile surface.
  159. 159. 5. UNSTERILE PERSONS AVOID REACHING OVER ASTERILE FIELD; STERILE PERSONS AVOID LEANINGOVER AN UNSTERILE AREAa. Unsterile circulating nurse NEVER reaches over a sterile field to transfers sterile items.b. In pouring solution into sterile basin, circulating nurse holds only lip of bottle over basin to avoid reaching over a sterile area.c. Scrub person sets basins or glasses to be filled @ edge of the sterile table; circulating nurse stands near this edge fo the table to fill them.d. Circulating nurse stands @ a distance from the sterile field to adjust light over it to avoid microbial fallout over field.
  160. 160. e. Surgeons turns away from sterilefield to have perspiration removed frombrow.f. Scrub persons drapes a nonsterile table towards self first to protect gown. Gloved hands are protected by cuffing draped over themg. Scrub persons stands back from nonsterile table when draping it to avoid leaning over an unsterile area.
  161. 161. 6. EDGES OF ANYTHING THAT ENCLOSES STERILECONTENTS ARE CONSIDERED UNSTERILE a. In opening sterile packages, a margin of safety is always maintained. The inside of wrappers is considered sterile within 1 inch of the edges. The circulating nurse opens top flap away from self, then turns the sides under. Ends of flaps are secured in hand so they do not dangle loosely. The last flap are secured in pulled toward person opening package, thereby exposing package contents away from nonsterile hand.
  162. 162. b. Sterile person lifts contents away from packagesby reaching down & lifting them straight up, holdingelbows highc. Steam reaches only area within the gasket of a sterilizer. Instrument trays should not touch edge of the sterilizer outside the gasket.d. Flaps on peel-open packages should be pulled back not torn, to expose sterile contents. Contents should be flipped or lifted upward & not permitted to slide over edges. Inner edge of the heat seal is considered the line of demarcation between sterile & unsterile.e. If a sterile wrapper is used as a table cover, it should amply cover the entire table surface. Only the interior & surface level of the cover are considered sterile.
  163. 163. f. After a sterile bottle is opened, contents must be used or discarded. Cap can be replaced without contaminating pouring edges.7. STERILE FIELD IS CREATED AS CLOSE AS POSSIBLE TO TIME OF USE• Sterile tables are set up just before the operation.• It is virtually impossible to uncover a table of sterile contents without contamination. Covering sterile tables for later use is not recommended.
  164. 164. 8. STERILE AREAS ARE CONTINUALLY KEPT IN VIEW a. Sterile person face sterile areas. b. When sterile packs are open in a room, or a sterile field set up, someone must remain in the room to maintain vigilance. Sterility cannot be ensured without direct observation. An unguarded sterile field should be considered contaminated.
  165. 165. 9. STERILE PERSONS KEEP WELL WITHIN THE STERILE AREAa. Sterile persons stand back at a safe distance from the operating table when draping the client.b. Sterile persons pass each other back to back at 360° turn.c. Sterile person turns back to nonsterile person or area when passing.d. Sterile person face sterile area to pass it.e. Sterile person asks nonsterile individual to step aside rather than risk contamination.f. Sterile persons stay within the sterile field. They do not walk around or go outside the room.
  166. 166. g. Movement within & around a sterile areas is kept to a minimum to avoid contamination of sterile items or persons.10. STERILE PERSONS KEEP CONTACT WITH STERILE AREAS TO A MINIMUMb. Sterile persons do not lean on sterile tables & on the draped client.c. Sitting or leaning against a nonsterile surface is a break in technique. If the sterile team sits to operate, they do so without proximity to nonsterile areas.
  167. 167. 11. UNSTERILE PERSON AVOID STERILE AREASa. Unsterile persons maintain a distance of at 1 foot (30 cm) from any area of the sterile field.b. Unsterile persons face & observe a sterile area when passing it to be sure they do not touch it.c. Unsterile persons never walk between two sterile areas, e.g., between sterile instrument tables.d. Circulating nurse restricts to a minimum all activity near sterile field.
  168. 168. 12. DESTRUCTION OF INTEGRITY OFMICROBIAL BARRIERS RESULTS INCONTAMINATION a. Sterile packages are laid on dry surfaces. b. If sterile package wrapped in absorbent material becomes damp or wet, it is resterilized or discarded. The package is considered nonsterile if any part of it comes in contact with moisture. c. Drapes are placed on a dry field. d. If solution soaks through sterile drape to nonsterile area, the wet area is covered with impervious sterile draped or towels.
  169. 169. e. Packages wrapped in muslin or paper are permitted to cool after removal from a sterilizer & before being placed on cold surface to prevent steam condensation & resultant contamination.f. Sterile items are stored in clean dry areas.g. Sterile package are handled with clean dry hands.h. Undue pressure on sterile packs is avoided to prevent forcing sterile are out & pulling unsterile air into the pack.
  170. 170. 13. MICROORGANISM MUST BE KEPT TOAN IRREDUCIBLE MINIMUMA. Skin cannot be sterilized. Skin is a potential source of contamination in every operation.2. Transient & resident flora are removed from skin around operative site of client & hands & arms of sterile team members by mechanical washing & chemical antisepsis.3. Gowning & gloving of operating team is accomplished without contamination of exterior of gowns & gloves.4. Sterile gloved hands do not directly touch skin & then deeper tissues. Instruments uses in contact with skin are discarded & not reused.
  171. 171. 4. If glove is torn or punctured by needle orinstrument, gloved is changes immediately. Needleor instrument is discarded from sterile field.5. Sterile dressing should be applied before draped are removed to reduce risk of the incision being touched by contaminated hands or objects.B. Some areas cannot be scrubbed. (Operative includes mouth, nose throat, or anus in various parts of the body such as GIT & vagina) to reduce number of microorganism & prevent them from scattering:3. Surgeons makes an effort to use a sponge only once, then discards it.• GIT, especially colon, is contaminated. Measure are used to prevent spreading this contamination.
  172. 172. C. Infected areas are grossly contaminated. Theteams avoids disseminating the contamination.D. Air is contaminated by dust & droplets2. Drapes over anesthesia screen or attached to IV poles separate anesthesia area from sterile field.3. Talking is kept to minimum in OR. Moisture droplets expelled with force into mask during process of articulating words.4. Movement around sterile field is kept to minimum to avoid air turbulence.5. Drapes are not flipped, fanned or shaken to avoid dispersion of lint & dust.

  230. 230. SPONGE, SHARPS, & INSTRUMENT COUNTSACCOUNTABILITY Is a professional responsibility that rests primarily on the scrub nurse & the circulator.COUNTING PROCEDURES Is a method of accounting for items put on the sterile table for use during the surgical procedure. Counts are performed for client & personnel safety, infection control, & inventory purposes.
  231. 231. 1. BASELINE COUNT DURING SET- UP FOR THE SURGICAL PROCEDURE Count all item before the surgical procedure begins & during the surgical procedure as each additional package is opened & added to the sterile field.2. CLOSING COUNT (FIRST CLOSING COUNT) Counts are taken before the surgeon starts the closure of a body cavity or a deep or large incision. Field count table floor3. FINAL COUNT (SECOND CLOSING COUNT) Performed before any part of a cavity or a cavity within a cavity is closed.
  232. 232. WOUND CLOSURE• Continuous suture (running stitch) – peritoneum & vessels because it provides leak proofs suture line.• Interrupted suture – each stitch is taken & tied separately.• Buried suture – suture is placed under the skin, buried either continuous or interrupted.• Purse-string method – a continuous suture is placed around a lumen & tightened, drawing fashion, to close the lumen.• Subcuticular suture – a continuous suture is placed beneath epithelial layers of skin I short lateral stitches
