Rocuronium with alfentanil and propofol allows intubation within 45 seconds

Following induction with alfentanil (20 micrograms kg-1) and propofol (2.0-2.5 mg kg-1), four groups of patients were given rocuronium to determine conditions for rapid sequence intubation. Two groups received 0.9 mg kg-1 and two groups received 0.6 mg kg-1. In one of each dose groups, intubation was attempted after 45 s and in the other after 60 s. Intubating conditions were scored on a four point scale but all were rated as excellent or good. Almost all intubating conditions were excellent in the 0.9 mg kg-1 groups.
