Abstract

Background: Optimal choice of inducing agent can partially modify the post induction hypotension, having a reported incidence of 9-40% in various studies. So, we compared the induction and recovery profile of the routinely available induction agents.
Materials and Methods: This prospective randomized, comparative study was carried out on 120, ASA 1 and II patients undergoing routine laparoscopic cholecystectomy. Patient received either thiopentone 5 mg/kg, propofol 2.0 mg/kg or 0.3mg/kg injection etomidate at induction in group T, P and E respectively. The time taken from the administration of inducing agent to loss of eyelash reflex was noted. Heart rate, systolic, diastolic and mean arterial pressure, SpO2 was recorded at 1, 2, 3, 4, 5, 6 minutes and every five minutes after intubation. Steward score and the vitals were noted every 5 minutes after extubation till 30 minutes. It was noted that how long it took to get a Steward score of 6.
Results: The mean induction time (sec) was 49.85 ±2.54 in group T, 43.45 ±2.66 in group P and 52.675 ±2.11 in group E. (p<0> Conclusion : Amongst the three agents, we recommend propofol as preferred agent for induction due to faster induction, better attenuation of intubation response, faster recovery and stable hemodynamic parameters.
