Comparison of hemodynamic stability of propofol ketamine versus etomidate ketamine during induction in peritonitis cases posted for emergency surgery

The aim: The aim of the present study is to evaluate the hemodynamic stability of propofol ketamine versus etomidate ketamine during induction of anaesthesia in peritonitis cases posted for emergency surgery. Methods: Sixty patients with peritonitis, posted for emergency surgery under general anaesthesia, were randomly allocated to two groups. Group propofol ketamine (P + K) comprised of 30 patients (n=30) were induced with propofol 1 mg/kg and ketamine 0.75 mg/kg IV. Group etomidate ketamine (E + K) comprised 30 patients induced with etomidate 0.3 mg/kg and ketamine 0.75 mg/kg. The hemodynamic effects of the combination of the drugs in both groups were compared before and after induction. Results: The change in saturation (SPO2) and Heartrate between the groups P+K & group E+K before induction and after intubation was similar in both groups. There was a statistically insignificant fall in systolic blood pressure (SBP) and diastolic blood pressure (DBP), and mean arterial pressure (MAP) in group P+K before and after induction when compared to group E+K. Conclusions: The propofol ketamine and etomidate ketamine combinations have a similar haemodynamic profile and are equally effective in maintaining haemodynamic stability during induction and intubation.
