BACKGROUND An ideal induction agent provides rapid and smooth onset of action, intraoperative amnesia and analgesia and optimal surgical conditions and adequate muscle relaxation with rapid recovery. Supraglottic airway devices are the most preferred technique of airway management for day care surgery. Etomidate, Propofol and Thiopentone with fentanyl provides optimal condition for supraglottic airway device insertion. The aim of this study was to compare the success rate of introducing i-gel (Supraglottic Airway Device) with induction agent etomidate, propofol and thiopentone in patients undergoing elective short surgical procedures. MATERIALS AND METHODS In a prospective, randomized, double blind study 90 patients scheduled for elective surgeries were assigned to one of three groups (n = 30). RESULTS The age and body weight of patients in three group were statistically analysed by analysis of variance test (Fisher test) found comparable between groups. The overall assessment of i-gel insertion was excellent in 50% Group-I, 67% in Group-II and 48% in Group-III (p< 0.05), which was statistically significant. Incidence of adverse response to airway manipulation in etomidate and thiopentone group was significantly higher than that of propofol group. CONCLUSION Propofol provides best conditions for i-gel insertion compared to etomidate and thiopentone. Propofol was associated with highest incidence hypotension and apnoea during induction, etomidate had least. Recovery in propofol and etomidate group was comparable whereas in thiopentone group recovery was significantly prolonged.
