Introduction: Successful insertion of Laryngeal Mask Airway (LMA) ProSeal without any unwanted effects, such as coughing and gagging, requires adequate depth anaesthesia and suppression of the upper airway reflexes. Our prime aim was to study Bispectral Index (BIS) guided conditions for LMA ProSeal insertion comparing Propofol versus Sevoflurane with or without Fentanyl citrate.
Materials and Methods: A randomised prospective study was done on 120 unpremedicated ASA grade 1 or 2 patients which were divided into four equal groups as group P – Propofol intravenous induction, group PF - Propofol intravenous induction with Fentanyl, group S – Sevoflurane gas induction in 60% nitrous oxide and 40% oxygen and group SF -Sevoflurane gas induction in 60% nitrous oxide and 40% oxygen with Fentanyl. The parameters studied were induction time, insertion time, insertion conditions for LMA ProSeal like jaw opening, ease of insertion, coughing, gagging, laryngospasm- airway obstruction and patients movements on a three point scale using six variables.
Result: Excellent and satisfactory conditions were in 100% patients in group SF, 90% patients in group PF and 66.7% in group P and S.

Conclusions: Overall, group PF is better than SF in having shorter induction time and better hemodynamic stability but insertion conditions were better with group SF as compared to group PF though statistically insignificant.

Keywords: ProSeal LMA, Propofol, Sevoflurane.
