title: A comparative study of effect of sevoflurane on intubating conditions with rocuronium in neurosurgical patients.
abstract: OBJECTIVE
  Rocuronium may not always be the preferred relaxant for rapid sequence intubation. When 2% sevoflurane is used in conjunction with rocuronium, it may reduce the time required for achieving complete skeletal muscle relaxation with the intubating dose of rocuronium.
  
  
  METHODS
  This study was prospective, randomised, double-blind in nature and compared the effect of sevoflurane on intubation time and intubating conditions when used along with rocuronium. Thirty adult patients belonging to American Society of Anesthesiologists physical status Grades 1 and 2, of either gender aged between 30 and 65 years undergoing neurosurgical operations were randomly allocated into two equal groups: Group R received 0.8 mg/kg rocuronium, and Group RS received 0.8 mg/kg of rocuronium with 2% sevoflurane. Onset time of intubation was assessed using train-of-four stimuli. The intubating conditions were compared using the Cooper scoring system and the haemodynamic responses were compared between the two groups.
  
  
  RESULTS
  The onset time of intubation was 101.73 ± 10.28 s in Group R and 60.4 ± 4.1 s in Group RS (P < 0.001), with excellent intubating conditions in both groups and without any adverse effects. Significant differences in heart rate and mean arterial pressure were seen immediately after intubation, at 1 and 3 min (P < 0.05) between the two groups.
  
  
  CONCLUSIONS
  Rocuronium 0.8 mg/kg along with 2% sevoflurane provides excellent intubating conditions within 60-66 s from its administration.
