Back ground: Today LMA has an established role as an airway device for elective surgeries as it offers advantage over tracheal tube with respect to lesser depth of anesthetic needed, allows avoidance of usage of muscle relaxant and less stimulation to airway. Methods: We conducted a prospective randomized double blind study on 80 ASA I- II patients, undergoing short surgical procedures of less than one hour. We aimed to compare the LMA insertion conditions using ketamine and butorphanol as an adjuvant to propofol.In group KP- ketamine 0.5mg/kg and group BP- butorphanol 20ug/kg was given prior to induction with propofol in a dose of 2.5mg/kg. Observations were made for adequacy of jaw relaxation, quality of insertion conditions and for any adverse events besides vital monitoring. Results: In our study, incidence of absolute jaw relaxation was highest in group BP (87.50%) than in group KP (45%). Excellent LMA insertion conditions were seen in 80% patients in group BP whereas in 45% of patients in group KP. Incidences of adverse events like lacrimation, coughing, gagging, patients’ movement were lower in group BP as compared to group KP. Conclusion: We conclude that the addition of 20ug/kg butorphanol to propofol anaesthesia provides better LMA insertion conditions along with better hemodynamic stability and lesser incidence of complications as compared to 0.5mg/kg ketamine as an adjuvant.
