Atropine Classification
Parasympathetic blocker, anticholinergic
Atropine Action
Cardiac:
1. Chronotropic effect of Increase SA node rate by blocking vagus nerve
2. Positive dromotropic effect in AV Node
Non-Cardiac:
1. decrease body secretions
2. dilate pupils and eye paralysis
3. Decrease bladder tone and increase urinary retention
4. CNS Stimulant

- Organophosphate, Nerve agent poisoning
- Pre-medication for pediatric intubation
Atropine Contraindication
- Afib/flutter
- HR>60
- Bradycardia due to ICP (stroke/trauma)
Atropine Use with Caution
- Do not mix with sodium bicarb
2. Be certain bradycardia not due to hypoxia or ICP
