Background: Ambulatory surgery continues to grow and thrive in vast majority (60-70%) of all surgical procedures is performed on day care basis. The speed of recovery from anaesthesia depends on the choice of anaesthesia technique1. Satisfactory insertion of the Laryngeal Mask Airway (LMA) after induction of anaesthesia requires sufficient depth for suppression of airway reflexes2. Objective: To compare 8% Sevoflurae and Propofol induction according to ease of laryngeal mask airway placement and hemodynamic effects in adult patients. Methods: This study was undertaken on 60 ASA grade I and II patients, aged between 18 to 60 years scheduled for day care surgical procedures at Silchar Medical College and Hospital, Silchar from December, 2011 to November, 2012. The patients were allocated into 2 groups and were administered Propofol (P) (n=30) 10 mg i.v. bolous and 8% Sevoflurane (S) (n=30). Results: Induction was more rapid with IV Propofol. In Group P, it was 54.03 ± 4.11 (S.D.) seconds and in Group S, 58.77 ± 5.51 (S.D.) seconds (p= 0.0004). Adequate jaw relaxation time in Group P was 80.27 ± 9.07 (S.D.) seconds shorter than Group S, which was 111.73 ± 11.57 (S.D.) seconds (p=0.0001). The mean time for successful LMA insertion was shorter in Propofol group which was 99.77 ± 8.32 seconds compared to Sevoflurane group which was 130.83 ± 10.91 seconds (p= 0.0001). Conclusion: In conclusion, we found that Propofol is superior to Sevoflurane for insertion of the Laryngeal Mask Airway.
