Background: Rocuronium (ORG 9426) has been shown to have an onset of action more rapid than other nondepolarizing neuromuscular blocking agents and to provide intubating conditions similar to those of succinylcholine 60–90 s after administration. We compared the intubating conditions and hemodynamic changes after the administration of rocuronium 0.6 mg kg −1 and lidocaine 1.5 mg kg −1 with rocuronium alone and succinylcholine 60 and 90 s after administration. Methods: One hundred and twenty‐five adult patients of ASA physical status I or II scheduled for elective surgery were randomly divided into five groups. After propofol administration in all patients, patients in group Su (succinylcholine), group R 60 (rocuronium) and group RL 60 (rocuronium‐lidocaine) were intubated within 60 s, while groups RL 90 and R 90 were intubated 90 s after the administration of rocuronium and succinylcholine. Laryngoscopy was performed and intubating conditions were graded by an experienced anesthetist blind to the muscle relaxant allocation. Results: In this study, groups Su, RL 60 , R 90 and RL 90 had similar intubation scores, which were significantly better than that for group R 60 . Heart rate did not increase after intubation in groups Su, RL 60 and RL 90 . Conclusion: The combination of lidocaine (1.5 mg kg −1 ) and low‐dose rocuronium (0.6 mg kg −1 ) along with propofol is clinically equivalent to succinylcholine, improves intubating conditions in 60 s and effectively blocks increases in heart rate after intubation.
