The choice of sedative agent significantly impacts first-attempt success in rapid sequence intubation (RSI). Thiopental, methohexital, and propofol appear to improve intubation conditions compared to other agents.

Area of Science:

  • Emergency Medicine
  • Anesthesiology
  • Critical Care

Background:

  • Rapid sequence intubation (RSI) is a critical procedure in emergency medicine.
  • Sedative agents play a role in facilitating intubation by inducing hypnosis.
  • The optimal sedative agent for RSI remains an area of investigation.

Purpose of the Study:

  • To determine if sedative agents influence the number of attempts and success rate of RSI.
  • To compare the efficacy of different sedative agents in emergency department intubations.

Main Methods:

  • Analysis of a prospective multicenter registry of emergency department intubations.
  • Conditional logistic regression was used to identify factors associated with intubation success.
  • Data from 3,407 intubations, including 2,380 RSI, were analyzed.

Main Results:

  • Sedative choice significantly affected the number of intubation attempts (p = 0.002).
  • Etomidate, ketamine, benzodiazepines, or no sedative were associated with a lower likelihood of first-attempt success compared to thiopental, methohexital, or propofol.
  • Higher doses of etomidate or succinylcholine improved first-attempt success in etomidate recipients.

Conclusions:

  • Thiopental, methohexital, and propofol seem to facilitate RSI in emergency settings.
  • These agents may improve intubating conditions, potentially by complementing muscle paralysis.
  • Deeper anesthesia may enhance RSI success in emergency patients.
