Abstract: Various anaesthetic agents are successfully used as induction agent for insertion of proseal laryngeal mask airway. This study was conducted comparing the efficacy of sevoflurane and propofol for insertion of proseal laryngeal mask airway in adults. Methods: This hospital based observational study was carried out after approval from the institutional ethics committee. 90 patients were divided equally and consecutively into two groups. Group P patients received intravenous propofol 1% 2.5 mg/kg body weight and group S patients received sevoflurane 8% with oxygen at 8 litres/minute. The time taken for induction and jaw relaxation number of attempts and condition for insertion of PLMA were noted. Also, the HR, SBP, DBP, MAP and SPO2 were noted. Result: Induction was significantly earlier in group P. The mean induction time of patients in group S was 54.02?3.88 and in group P was 42.15?2.75 seconds which was statistically significant (p<0.0001). Jaw relaxation time was statistically significant (p<0.0001) with mean jaw relaxation time of 79.91?4.50 seconds in group S and 63.33?4.50 seconds in group P. Excellent to satisfactory insertion conditions were seen in both the groups. Decline in heart rate was seen in both the groups at 2 minutes and5minutes after induction in comparison to the heart rate before induction. But, nosignificant difference was seen between the two groups. In both the groups, intragroupdecline in systolic and diastolic and mean blood pressure at 1 minute, 2 minutes and 5 minutes after induction were seen compared to that before induction. Conclusion: Induction was significantly faster with propofol. However, overall condition for insertion of PLMA was easy and comparable in both the groups. Thus, sevoflurane can be used as an alternative to propofol for insertion of PLMA.
