Pretreatment drugs for RSI
OVERVIEW
Traditionally there are four options for pretreatment for Rapid Sequence Intubation (RSI):
- atropine 20 mcg/kg IV — prevent bradycardia in children
- lignocaine 1.5mg/kg IV — sympatholytic, neuroprotection in head injury; decrease airway reactivity in asthma
- fentanyl 2-3 mcg/kg IV — sympatholytic, neuroprotection in head injury and vascular emergencies (e.g. myocardial ischaemmia, aortic dissection, subarachnoid haemorrhage)
- defasciculating dose of a non-depolarising neuromuscular blocker (e.g. rocuronium 0.1 mg/kg IV or vecuronium 0.01 mg/kg IV) — prevents fasciculations from suxamethonium (e.g. TBI)
Other agents suggested as pretreatment for rapid sequence induction:
- remifentanil
- gabapentin
EVIDENCE
- There is little evidence that any of these are beneficial clinically
- They should not be a routine part of clinical practice but may be considered in selected patients by skilled practitioners
