A comparative study to evaluate the effect of 8% sevoflurane compared to 1% Propofol for insertion of laryngeal mask airway in adult patients -A prospective, randomised & controlled study

The airway management during the general anaesthesia is mainly done using laryngeal mask airway. The anaesthesia that is used for this purpose is either propofol or sevoflurane supplied through inhalational route for painless insertion. Hence, the study was conducted with the aim of comparing 8% sevoflurane and 1% Propofol with regard to efficacy and associated complications. This prospective experimental study included adult subjects who were undergoing minor surgeries. The subjects were equally distributed into two groups. The Group-1 received propofol 2-2.5 mg/kg body weight and Group-2 received 8% sevoflurane. The study outcomes were determined induction characteristics such as loss of verbal contact, eyelash reflex, jaw relaxation and some attempts for insertion were assessed. The other parameters that were recorded were grading of the parameters, blood pressure, and heart rate and associated complications. A total of 60 participants were included in the study. Propofol took a lesser time for Induction characteristics as compared to that of sevoflurane. It was observed that propofol was associated with fall in heart rate and blood pressure and more rate of complications. Faster induction was observed in Propofol while good hemodynamic stability was associated with Sevoflurane.
