title: Comparison of intubating conditions following propofol and succinylcholine with propofol and remifentanil 2 micrograms kg-1 or 4 micrograms kg-1.
abstract: We evaluated the intubating conditions, haemodynamic responses and duration of apnoea in 60 healthy adult patients after propofol 2 mg kg-1 combined with either a bolus of remifentanil 2 micrograms kg-1 or 4 micrograms kg-1, or succinylcholine 1 mg kg-1. Patients intubated following remifentanil showed dose-dependent intubating conditions, similar at 4 micrograms kg-1 to the conditions produced with succinylcholine. Post-induction mean arterial pressure decreased from baseline values by 21% (P < 0.0001), 28% (P < 0.0001) and 8% (P > 0.05) in the remifentanil 2 micrograms kg-1, remifentanil 4 micrograms kg-1 and succinylcholine 1 mg kg-1 groups, respectively. The mean (SD) duration of apnoea following induction was 9.3 (2.6) min and 12.8 (2.9) min in the remifentanil 2 micrograms kg-1 and 4 micrograms kg-1 groups, and 6.0 (0.9) min in the succinylcholine group (P < 0.001 between groups).
