Aims: Presently Propofol and Etomidate are popular as rapid acting inducing agents. Due to reflex sympathetic stimulation, direct laryngoscopy and endotracheal intubation typically cause a cardiovascular stress response characterized by hypertension and tachycardia. This study is conducted to compare the effects of these two drugs on hemodynamic responses during induction and endotracheal intubation, to compare time of induction to choose the better induction agent and to study adverse effects of the two drugs, if any. Study Design: Prospective double blind study Place and Duration of Study: Department of anaesthesiology Dr D.Y Patil medical college hospital and research centre Pimpri Pune Duration -Sept.2018 -sept 2021. Methodology: This is prospective randomized double-blind study. 60 ASA I and II patients randomly divided into two groups group P and group E of 30 each of either sex in age group of 18-65 years posted for elective surgery under general anesthesia. Group P: (n-30) received 2.5mg/kg Propofol and Group E:(n-30) received 0.3mg/kg Etomidate for induction. vital parameters such as HR, SBP, DBP, MAP, and SPO2 recorded at baseline (T0), before induction (T1), after induction (T2), during laryngoscopy (T3 ) ,after intubation at 1min, 2min, 3min, 5min and at 10 min. Time of induction was taken as period between time of start of study drug till loss of eyelash reflex Conclusion: Induction time between the two study groups was statistically insignificant. (p>0.05) The fall in heart rate at post induction (T2), at 1 min, 2 min after intubation in Group P as compared to Group E was statistically significant, fall in SBP, DBP and MAP at post induction (T2), at 1 min, 2 min, 3 min and 5 min after intubation in Group P as compared to Group E was statistically significant. Pain on injection was more with propofol. However, myoclonus was more with etomidate.
