Question

Quizplus · Accepted Answer

Atropine is indicated for certain forms of sudden cardiac death,such as asystole or pulseless electrical activity,and the usual dose is 1 mg given as intravenous push.Epinephrine or vasopressin is usually given along with atropine.Atropine acts by blocking the actions of acetylcholine,an endogenous cholinergic agent.The cholinergic system is typically involved with heart rate reduction,and by blocking this effect,atropine exerts a pronounced (albeit short-lived)chronotropic effect on the heart.The recommended maximal dose of atropine used during resuscitation is 0.04 mg/kg.Because atropine affects acetylcholine globally within the body,some adverse effects may be noticed,such as miosis,dry mouth,urinary retention,and constipation.
