Transcript of "Aemt pharmacology-ver-2-4-2013 (2)"

  1. 1. AEMT- Medication Card Guidelines (2.2013) The AEMT must have knowledge of the following drugs for EMSP 1338. The student will prepare the drug cards and turn them in by the due date. Keep in mind that the student is preparing the cards to take into the clinical setting where they MUST know the drugs completely before being allowed to administer them to a patient. The guidelines needed to successfully complete this assignment are as follows: 1. The cards need to be done on Index cards in a spiral notebook; the other alternative is to do them on index cards and then place them in a binder of some sorts so the cards do not “fall out” after completing them. I will NOT take them LOOSE or held together with a binder clip since they can come loose easily. 2. The size of the cards is up to the student in what you are willing to carry but keep in mind that the smaller they are makes it easier to place them in your lab coat. 3. The following information must be on EVERY card. a. Class b. Mechanism of Action c. Indications d. Contradictions e. Side Effects f. Precautions g. How Supplied h. Administration/Dosage 4. THEY MUST BE LEGIBLE IN YOUR HANDWRITING – not anyone’s else’s. 5. The Packet will NOT be scanned into computers and made into drug cards. Commercial Drug Cards are also NOT acceptable either. 6. CARDS MUST BE HANDWRITTEN
  2. 2. 7. Under Side Effects Charts, the Key is the following: When it is underlined and has a “C”=COMMON; When it is Bolded and has italics= LT-Life Threatening EPINEPHRINE (1:1,000) Class: Sympathomimetic, vasopressor, bronchodilator Mechanism of Action - Catecholamine that stimulates alpha- and beta- adrenergic receptors 1. Beta1 stimulation leads to: - positive inotropic effects (↑ force of cardiac contraction) - positive chronotropic effects (↑ rate of cardiac contraction) - positive dromotropic effects (↑ conduction velocity) - increased cardiac output (CO) - increased myocardial oxygen requirements 2. Beta2 stimulation leads to: - peripheral vasodilation and bronchodilation 3. Alpha1 stimulation leads to peripheral vasoconstriction: - arterial / venous vasoconstriction (vasopressor) = increased SVR - constriction to renal, mesenteric, coronary, and cerebral vessels - pulmonary vasoconstriction - making the heart more susceptible to direct countershock in cardiac arrest (Ventricular fibrillation) = reason it is given during cardiac arrest 4. Inhibits histamine release (stops degranulation) during anaphylactic reaction (Effects start within 90 seconds and are short lived) Indications 1. Acute asthma attacks 2. Exacerbation of some forms of COPD 3. Mild anaphylaxis 4. Symptomatic Bradycardia (refractory, not responding, to oxygen and atropine) (infusion) 5. Symptomatic heart blocks (second type II and third degree) (infusion) Contraindications 1. Hypersensitvity 2. Patients with underlying cardiovascular disease 3. Tachyarrhythmias
  3. 3. 4. Not with alkaline drugs 5. Shock 6. Patients with hypertension EPINEPHRINE (1:1,000) Side Effects CNS Anxiety Dizziness Cardiovascular Anginal pain Dysrhythmias LT Hypertension Palpitations - LT Ischemia Headache Restlessness Subarachnoid Hemorrhage = LT Tremors Weakness Italic = C = common side GI / GU Nausea - C Vomiting-C Respiratory Dyspnea Urinary retention Skin Pallor Coldness Necrosis Urticaria Bold italics = LT = life-threatening reactions Precautions 1. Increased myocardial workload may lead to ischemia, infarction 2. May have increased airway resistance due to sulfites in the preparation = hypersensitivity 3. Use cautiously with: - Heart disease - Diabetes - Hypertension 4. Excreted into breast milk – use cautiously on nursing mothers How supplied - Ampules and prefilled syringes containing - 1mg/1ml - Vials containing: - 30mg/30cc Administration / dosage Administered – SQ / IM / IV infusion Mild Anaphylaxis or Acute Asthma Attack Refractory Bradycardia Eyes Pupil dilation
  4. 4. 0.3 to 0.5mg - IM / SQ Mix infusion: Every 15 – 20 minutes, PRN Dosage range: 1-2mg / 250 or 500cc 2-10µg / minute Low doses – 2-5µg / minute = β effects High doses – 5-10µg / minute = α effects EPINEPHRINE (1:10,000) Class: Sympathomimetic, vasopressor, bronchodilator Mechanism of Action - Catecholamine that stimulates alpha- and beta- adrenergic receptors 1. Beta1 stimulation leads to: - positive inotropic effects (↑ force of cardiac contraction) - positive chronotropic effects (↑ rate of cardiac contraction) - positive dromotropic effects (↑ conduction velocity) - 3 above help with rate post-arrest - increased cardiac output (CO) - increased myocardial oxygen requirements 2. Beta2 stimulation leads to: - peripheral vasodilation and bronchodilation 3. Alpha1 stimulation leads to peripheral vasoconstriction: - arterial / venous vasoconstriction (vasopressor) = increased SVR (perfusion pressure) - constriction to renal, mesenteric, coronary, pulmonary and cerebral vessels - makes the heart more susceptible to direct countershock in cardiac arrest (Ventricular fibrillation) (due to increased hydrostatic pressure) = reason it is given during cardiac arrest 4. Inhibits histamine release (stops degranulation) during anaphylactic reaction (Effects start within 90 seconds and are short lived) Indications 1. Asystole 2. Ventricular-Fibrillation/pulseless Ventricular-Tachycardia 3. Pulseless electrical activity (PEA) 4. Severe anaphylaxis Contraindications 1. Hypersensitvity 2. Patients with underlying cardiovascular disease 3. Tachyarrhythmias 5. Hypovolemic shock 6. Not with alkaline drugs Side Effects

Deactivated with sodium bicarbonate / lasix (alkaline solutions) 5. Patients on MAO inhibitors (Marplan, Nardil, Parnate) ← (Anti-depressant drugs) – potentiates the effects How Supplied - 1mg/10ml = 1:10,000 (prefilled syringe) Administration/Dosage Administered by: - IVP, IO, ET Cardiac Arrest 1mg (1:10,000) IVP or IO Followed by a 20cc flush and raising the patients arm Repeat every 3-5 minutes Endotracheal dose 2-2.5 times the IVP dose Use 1:1,000 and place in 10cc of fluid Use ONLY if IV or IO site cannot be established May produce transient β effects = vasodilation = ↓ Coronary perfusion pressure Severe Anaphylaxis: 1.0mg SIVP (1:10,000) over 5 minutes - Repeat in 5-15 minutes PRN (as needed)) Pediatric dose: Cardiac arrest - 0.01mg/kg IVP (0.1 mL/kg)
  6. 6. ASPIRIN Class: Nonsteroidal Anti-inflammatory Drug (NSAID), antipyretic, platelet inhibitor, nonnarcotic analgesic Mechanism of Action 1. 2. 3. 4. - Inhibits prostaglandin synthesis and release (from mast cells). This action: decreases pain and fever produced Antipyretic agent by: inhibition of prostaglandins action on hypothalamus heat-regulating center vasodilation and sweating Analgesic agent acts on peripheral nervous system Platelet inhibitor = prevents formation of thromboxane A2 Post-plaque rupture in vessels → “sticky” platelets adhere to damaged vessel (within 1-5 seconds) → platelets release thromboxane A2 (chemical causes → platelet aggregation and vasoconstriciton) Aspirin delivery leads to: - Vasodilation (platelet inhibitor / thromboxane A2 inhibitor) - Decreased clot formation (platelet inhibitor / thromboxane A2 inhibitor) - Reduces inflammation (inhibition of prostaglandin synthesis) - Reduces fever (inhibition of prostaglandin synthesis and antipyretic properties) - Pain reduction (analgesic property) IF STARTED WITHIN 24 HOURS OF ONSET OF ACUTE MI – IT REDUCES MORTALITY ALMOST TO THE SAME DEGREE OF THROMBOLYTIC THERAPY Indications 1. 2. 3. 4. 5. Mild to moderate pain and fever Reducing the risk of recurrent transient ischemic attacks (TIA) Chest pain or other signs/symptoms of acute MI EKG changes suggestive of acute MI To reduce inflammation Contraindications 1. 2. 3. Active ulcer disease Hemophilia Hemorrhagic states
  7. 7. 4. 5. - Active GI bleeding - Hemorrhagic stroke Known hypersensitivity to NSAIDs or salicylates Children or adolescents with flu-like symptoms / chickenpox (Varicella) ASPIRIN Side effects CNS Confusion Eyes / Ears Dim vision Dizziness Reversible hearing loss Tinnitus Drowsiness Headache Blood ↓ plasma iron concentration Leukopenia = LT GI Reversible hepatotoxicity Anorexia Metabolic Hypoglycemia Respiratory Hypernea Skin Angioedema Hypokalemia Wheezing Bruising Prolonged bleeding Diarrhea Hyponatremia Hives Shortened erythrocyte survival time Thrombocytopenia= LT Dyspepsia (inhibits pepsin) = GI discomfort = C Peptic ulcer formation Bleeding Heartburn Bronchospasms Laryngeal edema Italic = C = common side effects Nausea = C Bold Italic = LT = life-threatening reactions Precautions 1. Chronic use may lead to GI ulcerations, bleeding, or perforation 2. Alcohol may increase the risk of GI bleeding 3. Allergic reactions are more likely if the patient has a history of asthma (hypersensitivity) 4. Use cautiously with: - GI disorders - Asthma - Impaired renal / liver function - Dehydrated children - Histories of coagulation defects - Bleeding disorders Rash Urticaria
  8. 8. Administration / Dosage Administered - PO (orally) – Mild pain and fever Myocardial Infarction 160-325mg / day - PO 325-650mg - PO NON-ENTERIC – chewing is preferred NITROGLYCERIN (NITROSTAT) Class: antianginal, vasodilator, and nitrate Mechanism of action 1. Relaxes vascular smooth muscle - promoting vasodilation 2. Decreases preload (predominately) - venous dilation = ↓ preload = ↓ heart size - ↓ heart size = ↑ blood flow to coronary and collateral vessels = myocardial perfusion is improved 3. Decreases afterload - ↓ arteriole pressure = ↓ aortic pressure = left ventricle works better 4. Decreases myocardial O2 consumption / workload 5. Improves collateral flow to ischemic regions 6. Dilates pulmonary capillary beds - fluid in alveoli and interstitial space are pulled back into the vessels Pain relief occurs within 2 minutes & therapeutic effects observed up to 30 minutes.

Protein secreted by alpha cells of the pancreas. When released results in blood glucose elevation by increasing the breakdown of glycogen to glucose (glycogenolysis) and stimulating glucose synthesis (gluconeogenesis). 2. Only effective in treating hypoglycemia if liver glycogen is available and therefore may be ineffective in chronic states of: a. Hypoglycemia b. Starvation c. Adrenal insufficiency 3. Exerts (+) inotropic action on the heart and decreases renal vascular resistance a. Why used to manage patient with beta-blocker and calcium-channel blocker cardiotoxicity (that do not respond to other conventional therapy) Indications: 1. Altered LOC when hypoglycemia is suspected 2. Beta-blocker and calcium channel blocker toxicity. Contraindications: 1. Hyperglycemia 2. Hypersensitivity to proteins Side effects CNS Cardiovascular GI tachycardia Hypotension Vomiting=C common side effects=C GU Respiratory Skin Urticaria
