- used in the treatment of symptomatic sinus bradycardia (not recommended for bradycardias below AV node such as Type II 2o, or complete AV block)
- antidote for sinus bradycardia induced by drugs or toxic substances or neurological disorders (which may be induced by suctioning)
- reduces salivation and excessive secretions of the respiratory tract
- 0.5-1mg q3-5min until desired rate achieved
- when used as a cholinergic antidote may require larger frequent doses
- slow IV administration may result in paradoxical bradycardia and is not recommended
- may be given via endotracheal tube if IV administration not possible
- respiratory depression
- blurred vision
- dilated pupils
- dry mouth
- flushed dry skin
- urinary retention
- in myasthenia gravis, glaucoma, paralytic ileus, urinary obstruction
- atropine + phenothiazines = increased anticholinergic effect
- atropine + quinidine = increased anticholinergic effect
- atropine + procainamide = increased anticholinergic effect
- continuous heart rate and rhythm
- blood pressure
|Adult Critical Care Protocol:
- May be administered IV direct by an approved nurse in the CCTC.
- May be administered as 0.5mg IV direct my medical directive by a certified nurse or RRT in Adult Critical Care for symptomatic bradycardia <60 beats/min and at least one sign or symptom (i.e. hypotension, decreased level of consciousness, signs of shock or myocardial ischemia/pain).
A certified nurse or RRT may administer additional doses of 1 mg every 3 minutes to a maximum total dose of 3 mg.
