Ketamine is an appropriate alternative in rapid-sequence intubation, say researchers.

Use of rapid-sequence intubation (RSI) in the prehospital setting is controversial. In a prospective crossover trial, these authors compared laryngoscopy conditions and intubation success rates ...

We hypothesized that morphine might induce prolonged neurodepression, independent of blood pressure, as compared with rapid sequence induction/intubation (RSI).

Rapid Sequence Induction (RSI): An approach to quickly induce unconsciousness and neuromuscular blockade, minimising the time to secure the airway during intubation.
