ABSTRACT
Introduction: An ideal induction agent for general anesthesia should have hemodynamic stability, minimal respiratory side effect and rapid recovery. Presently etomidate and propofol are popular rapid acting inducing agents. Material and methods: After obtaining informed written consent from patients this prospective, randomized, double blind study was conducted in 100 patients of ASA grade 3 and 4 posted for elective surgeries under general anaesthesia. They were divided into two groups of 50 in each group based on random number as group A and group B. The patients in Group A given Inj. Propofol and the patients in Group B received Inj. Etomidate. Parameters such as heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure and spo2 were monitored continuously and recorded. Incidence and degree of pain of myoclonic movements were recorded. Demographic variables such as age,Result: gender, weight and ASA grade were comparable no significant difference existed between both the groups.Baseline mean heart rate, mean systolic blood pressure and mean diastolic blood pressure were comparable in both the Groups. (P>0.05)Significant (P<0.05) fall in mean systolic blood pressure, mean diastolic pressure and mean arterial pressure was observed immediately after induction, at 2, 5, 10 minutes up to 30 minutes in group A (propofol) compare to group B (etomidate). After then no significant difference seen in mean systolic pressure, mean diastolic pressure and mean arterial pressure. Etomidate was found ideal for its hemodynamic stability when compared to PropofolConclusion: along with less incidence of pain on injection, the only drawback being high incidence of myoclonus elderly patient.
