Rocuronium with alfentanil and propofol allows intubation within 45 seconds

Area of Science:

• Anesthesiology
• Pharmacology

Background:

• Rapid sequence intubation (RSI) requires effective neuromuscular blockade.
• Rocuronium is a common neuromuscular blocking agent used in RSI.

Purpose of the Study:

• To evaluate the efficacy of different rocuronium doses for rapid sequence intubation.
• To compare intubating conditions at 45 and 60 seconds post-administration.

Main Methods:

• Patients received alfentanil and propofol for induction.
• Four groups received either 0.6 mg kg-1 or 0.9 mg kg-1 of rocuronium.
• Intubation was attempted at 45 or 60 seconds after rocuronium administration.
• Intubating conditions were assessed using a four-point scale.

Main Results:

• All intubating conditions were rated as excellent or good across all groups.
• The 0.9 mg kg-1 rocuronium groups demonstrated almost exclusively excellent intubating conditions.
• Both 45-second and 60-second intubation attempts yielded high-quality conditions with the higher dose.

Conclusions:

• Rocuronium at a dose of 0.9 mg kg-1 ensures excellent intubating conditions for rapid sequence intubation.
• The timing of intubation attempt (45 vs. 60 seconds) did not significantly compromise intubating conditions with the higher rocuronium dose.
