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.

Background:There is a delicate balance between respiratory tract anatomy, its physiology, physiological response to anesthetic agents, and airway management. The traditional gadgets to secure airway are face masks or endotracheal tubes. Recently, laryngeal mask airway (LMA) is gaining popularity. It does not require laryngoscopy thereby minimizing hemodynamic responses. For LMA placement, propofol is the induction agent of choice. Propofol, when used alone, requires large doses and leads to undesirable cardiorespiratory depression. To culminate its dose, various adjuncts are combined with it.Aim:Comparison of hemodynamic response of LMA using either butorphanol or fentanyl (according to group allocated) in combination with propofol.Methodology:Hundred patients scheduled for various surgical procedures were randomly selected and divided into two groups of 50 patients each, Group F (propofol and fentanyl) and Group B (propofol and butorphanol). One minute after giving intravenous (IV) opioids, induction was achieved with IV propofol 2.5 mg/kg. Depth of anesthesia was assessed, and LMA was inserted. Hemodynamic variables were measured before premedication, after premedication; 1, 3, and 5 min after insertion and after extubation of LMA.Results:After insertion of LMA, statistically significant drop in mean heart rate, systolic blood pressure (BP), diastolic BP, and mean BP was noted in Group F as compared to Group B (P < 0.05).Conclusion:The use of propofol-butorphanol combination produces stable hemodynamics as compared to propofol-fentanyl combination.
