RESUMO
The objective of current study was to compare the efficacy of three different anaesthesia induction approachesi.e. Inj propofol, Inj etomidate and admixture of Inj propofol and Inj etomidate in maintaining hemodynamicstability during induction and following Proseal LMA insertion in laparoscopic cholecystectomy. Patientswere randomly divided in to 3 groups with 90 patients each and received 2.5mg/kg of propofol(P), 0.3mg/kgof etomidate(E) and 1mg/kg of propofol+0.2mg/kg of etomidate which was mixed in a 20ml syringe. We alsostudied side-effects like PONV, myoclonus, pain on Injection, allergic reactions and thrombophlebitis. Wefound that the use of P-E admixture for induction of Proseal LMA provides hemodynamic stability as itprevents hypotension caused by propofol and also hypertension caused by etomidate when used alone. Admixturewas also associated with less incidence of other side effects like PONV, pain on Injection and myoclonus. Weconcluded that combination of propofol and etomidate for induction of anaesthesia for Proseal LMA issignificantly better than either drug used alone
