Comparison of haemodynamic response to induction with propofol versus etomidate in patients scheduled for elective surgery

Introduction: Laryngoscopy and endotracheal intubation are harmful stimuli that can produce adverse response in the cardiovascular, respiratory and other physiological systems. These changes are reflected in haemodynamic parameters which can be fatal for patients with low cardiac reserve and may alter the balance between myocardial oxygen supply and demand and as a result, myocardial ischemia can be precipitated. This observational comparative study was conducted to compare the haemodynamic effects of Propofol and Etomidate during induction of general anaesthesia in patients scheduled for elective surgery. Materials and Methods: 58 patients of American Society of Anaesthesiologists (ASA) physical status  I and II of age group 18-60 years scheduled for elective surgeries under general anaesthesia were randomly assigned in two groups (n=28). Group P received injection Propofol (2.5mg/kg) and group E received injection Etomidate (0.3mg/kg) during induction. Hemodynamic parameters were recorded at various time intervals. Statistical analysis was done using software (MedCalc Version 20.014). P value was considered significant if p £ 0.05. Results: Demographic profile was comparable in both the groups. Hemodynamic parameters at baseline and after premedication were comparable
