| atropine | <drug> A toxic alkaloid extracted from belladonna and other members of thenightshade family, it is typically used to dilate the eye and to stopmuscular spasms. Pharmacologic action: Parasympatholytic. Competitive blockade of acetylcholine at muscarinic receptors. Increases sinus node automaticity and AV conduction. Uses: Treat bradycardia, asystole, and AV block Dose: 0.5 - 1.0 mg for bradycardia every 3 - 5 min to a total dose of 0.04 mg/kg. Doses smaller than 0.5 mg can cause a paradoxical bradycardia due to sympathomimetic effects Typically 3 mg is adequate to completely block vagal effects Atropine is well absorbed via endotracheal route - administer 1-2 mg diluted in 10 mL sterile water or normal saline. Potential complications: 1. Tachyarrhythmias 2. Exacerbation of myocardial ischemia 3. Low dose may cause paradoxical bradycardia 4. Dry mouth, urinary retention, flushed and hot skin 5. Crosses blood-brain barrier which can cause delirium Note: The denervated heart will not respond to atropine. (15 Mar 2000) |

| atrial natriuretic peptide |
(ANP) a hormone involved in natriuresis and the regulation of renal and cardiovascular homeostasis. It is generally 28 amino acids in length but varies somewhat; it is synthesized as a prohormone in the granules of the myocytes of the atrium and is released into the circulation in response to atrial dilatation or increased intravascular fluid volume. ...
