The document discusses the history and types of anesthesia, from ancient civilizations using plants for pain management to the development of modern general anesthesia with ether and chloroform in the 1800s. It also covers regional anesthesia techniques like spinal blocks and local infiltration, as well as the different classes of drugs used for induction, maintenance, analgesia, and muscle relaxation during general anesthesia. The choice of anesthesia depends on factors like the procedure, patient health, and surgeon requirements.
Anesthesia

Chronic obstructive pulmonary disorders COPD is a [preventable and treatable disease with some significant extra pulmonary effects that may contribute to the severity in individual clients.
It is characterized by airflow limitation that is not completely reversible.
Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical purposes.
Local anesthetics block the nerves that connect a particular body part or region to the brain, preventing the nerves from carrying pain signals to your brain. Examples include novocaine shots, which dentists use to numb the nerves in your mouth during a root canal, and epidurals, which allow for a (relatively) painless childbirth by blocking the nerves that originate at the base of the spinal cord and serve the pelvic region.
For serious surgeries that require a patient to be completely unaware, doctors turn to general anesthesia. This renders patients unconscious with no perception or memory of the surgery (though pain from the surgical procedure will be apparent once you wake up). It also limits the physiological responses to surgical cuts, keeping blood pressure, stress hormone release and heart rate constant during the procedure.
Acute respiratory distress syndrome (ARDS) is a sudden, progressive form of respiratory failure characterized by severe dyspnea, refractory hypoxemia, and diffuse bilateral infiltrates.

Damage to the spinal cord above the sacral region causes reflex incontinence. This condition causes loss of voluntary control of urination; but the micturition reflex pathway often remains intact, allowing urination to occur without sensation of the need to void
Overflow incontinence occurs when a bladder is overly full and bladder pressure exceeds sphincter pressure, resulting in involuntary leakage of urine. Causes often include head injury; spinal injury; multiple sclerosis; diabetes; trauma to the urinary system; and postanesthesia sedatives/hypnotics, tricyclics, and analgesia
Hyperreflexia, a life-threatening problem affecting heart rate and blood pressure, is caused by an overly full bladder. It is usually neurogenic in nature; however, it can be caused functionally by blockage
Diseases that cause irreversible damage to kidney tissue result in end-stage renal disease (ESRD).
uremic syndrome- An increase in nitrogenous wastes in the blood, marked fluid and electrolyte abnormalities, nausea, vomiting, headache, coma, and convulsions characterize this syndrome. As the uremic symptoms worsen, aggressive treatment is indicated for survival
Nocturia - awakening to void one or more times at night
An excessive output of urine is polyuria.
. A urine output that is decreased despite normal intake is called oliguria.
increased urine formation (diuresis)
a stoma (artificial opening)
Urinary Retention. Urinary retention is an accumulation of urine resulting from an inability of the bladder to empty properly.
URINE OVERFLOW- The sphincter temporarily opens to allow a small volume of urine (25 to 60 mL) to escape. With retention a patient may void small amounts of urine 2 or 3 times an hour with no real relief of discomfort or may continually dribble urine.
pain or burning during urination (dysuria) as urine flows over inflamed tissues
blood-tinged urine (hematuria)
Urinary incontinence is the involuntary leakage of urine that is sufficient to be a problem. It can be either temporary or permanent, continuous or intermittentUrinary elimination depends on the function of the kidneys, ureters, bladder, and urethra. Kidneys remove wastes from the blood to form urine. Ureters transport urine from the kidneys to the bladder. The bladder holds urine until the urge to urinate develops. Urine leaves the body through the urethra. All organs of the urinary system must be intact and functional for successful removal of urinary wastes. Intact efferent and afferent nerves from the bladder to the spinal cord and brain must be present
INTAKE AND OUTPUT OF URINE
Assess the patient’s average daily fluid intake.
at home, ask him or her to estimate his or her intake by showing a measurement on a commonly used glass or cup
Special receptacles (urimeters) that attach between indwelling catheters and drainage bags are a convenient means of accurately measuring urine volume. A urimeter holds 100 to 200 mL of urine. After measuring urine from a urimeter, drain the cylinder

CRISPR-Cas9, a revolutionary gene-editing tool, holds immense potential to reshape medicine, agriculture, and our understanding of life. But like any powerful tool, it comes with ethical considerations.
Unveiling CRISPR: This naturally occurring bacterial defense system (crRNA & Cas9 protein) fights viruses. Scientists repurposed it for precise gene editing (correction, deletion, insertion) by targeting specific DNA sequences.
The Promise: CRISPR offers exciting possibilities:
Gene Therapy: Correcting genetic diseases like cystic fibrosis.
Agriculture: Engineering crops resistant to pests and harsh environments.
Research: Studying gene function to unlock new knowledge.
The Peril: Ethical concerns demand attention:
Off-target Effects: Unintended DNA edits can have unforeseen consequences.
Eugenics: Misusing CRISPR for designer babies raises social and ethical questions.
Equity: High costs could limit access to this potentially life-saving technology.
The Path Forward: Responsible development is crucial:
International Collaboration: Clear guidelines are needed for research and human trials.
Public Education: Open discussions ensure informed decisions about CRISPR.
Prioritize Safety and Ethics: Safety and ethical principles must be paramount.
CRISPR offers a powerful tool for a better future, but responsible development and addressing ethical concerns are essential. By prioritizing safety, fostering open dialogue, and ensuring equitable access, we can harness CRISPR's power for the benefit of all. (2998 characters)
4. Anesthesia
From Greek anaisthesis means
not sensation
Listed in Bailey´s English
Dictionary 1721.
When the effect of ether was
discovered anesthesia” used as a
name for the new phenomenon.
7. HISTORY OF ANESTHESIA
• General anesthesia was absent until the mid-
1800s.
• Ether synthesized in 1540 by Cordus
• Ether used as anesthetic in 1842 by Dr. Crawford
W.Long
• Ether publicized as anesthetic in 1846 by Dr.
William Morton.
• Ether is no longer used in modern practice, yet
considered to be the first ‘ideal’ anesthetic
• Chloroform used as anesthetic in 1853 by Dr. John
Snow
• Endotracheal tube discovered in 1878
• Thiopental first used in 1934
8. Pre 1846 - The Foundations of
Anaesthesia
……..so the Lord God caused him to fall
into a deep sleep. While the man
was sleeping, the Lord God took out
one of his ribs. He closed up the
opening that was in his side……...

9. Primitive Anesthesia
Ancient civilizations- opium poppy,
coca leaves, mandrake root,
alcohol
Regional anesthesia in ancient
times- compression of nerve
trunks or the application of cold
(cryoanalgesia)
10. World Anaesthesia Day

19. INTRODUCTION
• General anaesthetics (GAs) are drugs which produce
reversible loss of all sensations and consciousness. It usually
involves a loss of memory and awareness with insensitivity to
painful stimuli, during a surgical procedure
General anesthesia
need for
unconsciousness
‘Amnesia-hypnosis’
need for analgesia
‘Loss of sensory and
autonomic reflexes’
need for muscle
relaxation
42. Local anaesthetics
Lignocaine- quick/short acting
Bupivacaine/levobupicvacaine
- slow and long action
Ropivacaine- as above
Amethocaine- topical
Prilocaine- intravenous
43. Advantages
Effective alternative to GA
Avoids polypharmacy
Allergic reactions
Extended analgesia
Patient can remain awake
Early drink/feed
44. Disadvantages
Limited scope
Higher failure rate
Time constraints
Anticoagulants/Bleeding
diathesis
Risk of neural injury
45. Patient is more important
than our ego; call for help,
whenever patient is in

47. Choice of anesthesia
The patient´s understanding and wishes regarding the type of
anesthesia that could be used
The type and duration of the surgical procedure
The patients´s physiologic status and stability
The presence and severity of coexisting disease
The patient´s mental and psychologic status
The postoperative recovery from various kinds of anesthesia
Options for management of postoperative pain
Any particular requiremets of the surgeon
There is major and minor surgery but only major
anesthesia
48. Types of anesthesia care
General Anesthesia
Reversible, unconscious state is
characterised by amnesia (sleep,
hypnosis or basal narcosis),
analgesia (freedom from pain)
depression of reflexes, muscle
relaxation
Put to sleep
49. Types of anesthesia care
Regional Anesthesia
A local anethetic is injected to
block or ansthetize a nerve or
nerve fibers
Implies a major nerve block
administered by an
anesthesiologist (such as spinal,
epidural, caudal, or major
peripheral block)
50. Types of anesthesia care
Monitored anesthesia care
Infiltration of the surgical site with a local
anesthesia is performed by the surgeon
The anasthesiologist may supplement the
local anesthesia with intravenous drugs
that provide systemic analgesia and
sedation and depress the response of the
patient´s autonomic nervous system
51. Types of anesthesia care
local anesthesia
Employed for minor procedures in which the
surgical site is infiltrated with a local anesthetic
vital signs
May injsuch as lidocaine or bupivacaine
A perioperative nurse usually monitors the
patient´s ect intravenous sedatives or analgesic
drugs
