Background: Laryngeal mask airway (LMA) is a supraglottic device which requires lesser depth of anaesthesia, evokes lesser hemodynamic response and causes lesser stimulation of airway as compared to traditional definitive airway device endotracheal tube. Its placement is possible without muscle relaxants thereby allowing maintenance of anaesthesia on spontaneous respiration thus preventing apnoea or minimizing apnoea time. Propofol, the commonly used induction agent, causes cardiorespiratory depression at higher induction doses. To attenuate this, co-induction agents combined with propofol has been a regular I/V anaesthetic technique these days. Aim: Comparing apnoea time, recovery time and sedation scores using propofol-fentanyl and propofol-butorphanol combination. Methodology: Hundred patients scheduled for various elective surgical procedures were randomly selected and divided into two groups of 50 each. As coinduction drug Group F received fentanyl and Group B received butorphanol. In both the groups induction was achieved with I/V propofol and LMA was placed. Apnoea time was noted after induction. Recovery time and sedation scores were recorded after anaesthetic agents were turned off. Results: As compared to group F apnoea time was significantly less and recovery time was significantly more in group B (P < 0.05). Statistically postoperative sedation was significantly higher in group B than in group F at 1/2 hr but clinically, majority were responding to verbal commands. At 1 hour no significant difference in sedation was noted between the groups. Conclusion: Considering respiratory and recovery profile propofol -butorphanol combination is a safer alternative to propofol-fentanyl combination for LMA insertion.
