Inhalational sevoflurane and intravenous propofol have been widely used for anesthesia induction. This study compared the efficacies of inhalational sevoflurane and intravenous propofol inductions for laryngeal mask airway (LMA) insertion for minor surgical procedures. METHODS: Fifty adult patients of ASA I and II between the ages 18-60 years of either sex posted for elective, minor surgeries in general surgery, obstetric, gynecological, urologic and orthopedic surgeries, received anesthesia induction with inhalational sevoflurane and intravenous propofol. Induction time, quality and ease of LMA insertion, hemodynamic changes and complications were observed. RESULTS: LMA was inserted most rapidly with intravenous propofol (100.8±14.48 s) and less rapidly with inhalational sevoflurane (122±15.6 s). Anesthesia induction with intravenous propofol produced statistically significant difference with mean arterial pressure and heart rate at one minute, when compared with inhalational sevoflurane. The LMA insertion was excellent with intravenous propofol than inhalational sevoflurane. CONCLUSION: Inhalational sevoflurane provides a smoother induction with a stable hemodynamic profile, but requiring a longer time for LMA insertion in premedicated patients. The quality of anesthesia provided with intravenous propofol is superior. Thus inhalational sevoflurane is an acceptable alternative to intravenous propofol for LMA insertion in adults.
