AbstractEighty ASA I-III patients were randomly assigned to four groups. Group I patients received rocuronium 0.6 mg kg-1 immediately prior to thiopentone, while patients in group II received the same dose immediately after the induction agent. In groups III and IV a priming dose of rocuronium 0.04 mg kg-1 was administered prior to induction. Group III patients received rocuronium immediately prior to thiopentone. In group IV, suxamethonium 1.5 mg kg-1 was administered immediately after thiopentone. Intubation conditions were scored by a blinded investigator. An intubation time of > 60 s was defined as a failure. All patients could be intubated within 60 s. Priming with rocuronium did not improve intubation conditions. Total intubation scores > 6 occurred significantly more often in group II (P < 0.01 vs. all other groups). A single bolus dose of rocuronium 0.6 mg kg-1 (2 x ED95) administered immediately prior to thiopentone 6 mg kg-1 offers the same intubation conditions as suxamethonium 1.5 mg kg-1.
