Fall Final Flashcards
(167 cards)
Glucagon pharmacokinetics
onset: 5-20 min (IM)
aspirin
precautions
None in prehospital setting.
Atropine Sulfate: Indications
Symptomatic bradycardia, organophosphate poisoning, nerve agent poisoning. Atropine is considered ineffective for bradycardia associated with high-level AV blocks (2nd degree type II and 3rd degree). In these cases , consider pacing or dopamine first.
epinephrine: side effects
increased myocardial oxygen demand, ischemia, tachydysrhythmias, and anxiety.
Lorazepam (Ativan): Contraindications
Hypotension, head injury and/or decreased mental status unless being given during RSI
lidocaine: interactions
Except for V-fib and pulseless V-tach, lidocaine should not be given concurrently with other antidysrhythmics.
Glucagon Mechanism of Action
Causes a breakdown of glycogen stores in the liver into glucose, raising circulating blood glucose. Glucagon has positive inotronic and chronotropic effects on the heart that are independent of beta-adrenergic receptors which is why it is useful with beta blocker overdose.
Naloxone Hydrochloride: Contraindications
None
Albuterol (Ventolin): Pharmokinetics
Onset: Immediate
Albuterol (Ventolin): Contraindications
None in prehospital setting
Lorazepam (Ativan): class
benzodiazepine, anticonvulsant, sedative, hypnotic
amiodarone: how supplied
Vial or preload syringe of 150 mg/3 mL.
Glucagon supplied
Powder form, must be reconstituted
dopamine: side effects
increased myocardial oxygen demand, ischemia, tachydysrhythmias.
Naloxone Hydrochloride: Mechanism of action
Competitively displaces opioid analgesics from their receptor sites, reversing their effects. Respiratory depression, sedation, papillary miosis, and euphoric effects will be reversed.
diazepam (Valium):pharmacokinetics
Onset: 2-4 minutes
Duration: 30-90 minutes
Morphine Sulfate: Interactions
Potentiates other CNS depressants. Use caution with patients who have been drinking alcohol.
Dopamine: how supplied
prefilled syringes and ampoules of either 400 or 800 mg. Premix bags with either 400 or 800 mg in 250 to 500 mL. Concentrations of mixtures vary, but most commonly are 1600 mcg/mL
Albuterol (Ventolin): Indications
Asthma, COPD, wheezing associated with pulmonary edema (cardiac asthma), shortness of breath associated with pneumonia or anaphylaxis. May be used for symptomatic hyperkalemia
Albuterol (Ventolin): Side Effects
Hypertension, tachycardia, anxiety, palpatations
amiodarone: mechanism of action
Antidisrhythmic blocking sodium, potassium, and calcium channels. It is also a week, noncompetitive, alpha and beta blocking agent. amiodarone depresses automaticity of the sinoatrial node. It slows conduction and decreases refractoriness of the AV node. Amiodarone increases atrial and ventricular refractoriness and prolongs the QT interval.
Dopamine: interactions
sodium bicarbonate can deactivate catecholamines. MAO inhibitors potentiate the effects of dopamine (Marplan, Eutonyl, Parnate, Nardil)
diazepam (Valium): mechanism of action
Enhances action of GABA, an inhibitory
neurotransmitter, which inhibits spread of electrical
activity from irritable focus during seizures, calms CNS.
Also a muscle relaxant.
Glucagon precautions
Ineffective with patients who have reduced glycogen stores
