Succinylcholine improved first-attempt intubation success and reduced the number of attempts during air medical rapid-sequence intubation (RSI) compared to rocuronium. Further randomized studies are recommended to confirm these findings.
Area of Science:
- Emergency Medicine
- Anesthesiology
- Critical Care
Background:
- Rocuronium and succinylcholine are neuromuscular blocking agents used in rapid-sequence intubation (RSI).
- Their comparative effectiveness in air medical RSI is not well-established.
- This study addresses the knowledge gap regarding their impact on intubation success in prehospital settings.
Purpose of the Study:
- To evaluate the impact of succinylcholine on the success rate of prehospital intubation.
- To compare the effectiveness of succinylcholine versus rocuronium in air medical rapid-sequence intubation.
Main Methods:
- Retrospective analysis of a critical care transport database (2004-2008).
- Included adult patients requiring airway management with rocuronium or succinylcholine.
- Propensity score adjustment and logistic regression were used to analyze first-attempt intubation success and number of attempts.
Main Results:
- Succinylcholine was associated with a higher incidence of first-attempt intubation (OR 1.4, 95% CI 1.1-1.8).
- Succinylcholine use improved the odds of requiring fewer intubation attempts (OR 1.5, 95% CI 1.2-1.9) compared to rocuronium.
- Of 1,045 patients, 46% received succinylcholine, and 59% were intubated on the first attempt.
Conclusions:
- Succinylcholine demonstrated greater success with fewer attempts in air medical RSI compared to rocuronium.
- Prospective, randomized studies are needed to validate these findings.
- Further research should explore succinylcholine's impact on overall outcomes in air medical transport.

Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because succinylcholine...
