Background and objectiveThe development of modern anesthetic agents has made it possible to conduct pain-free surgical procedures. The role of the anesthetist in choosing a suitable anesthetic agent to provide a good anesthetic and sedative effect is very important in any surgical procedure. There is always a degree of risk involved as the hemodynamic parameters may be altered. This study aimed to compare the hemodynamic changes and respiratory effects between the use of etomidate and propofol for the induction of general anesthesia (GA) as well as to compare the side effects of both drugs in daycare surgeries. MethodsThe study was a parallel-design, randomized, double-blinded control trial conducted over a period of three years among patients undergoing elective daycare surgeries under GA. The patients were classified into two groups depending on the type of drug received: Group A or the propofol group and Group B or the etomidate group. Randomization was done by computer-generated random number generator software. A total of 174 patients were selected (87 in each group) at a ratio of 1:1. A baseline evaluation of the hemodynamic parameters was done followed by continuous monitoring. ResultsThe age, weight, and gender distribution of the patients in both groups were comparable. Significant hemodynamic changes were observed following induction in Group A. The fall in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial blood pressure (MABP) in Group A following induction was found to be statistically significant (p<0.00). The rise in heart rate was almost similar in both groups, with Group A demonstrating a slightly higher rate. There were fewer signs of respiratory depression in Group B. The major side effects observed after induction were myoclonus, which was more prevalent in Group B patients (21.84%), and pain at the injection site, which was observed more frequently in Group A (17.1%). ConclusionBased on our findings, etomidate is a drug with better hemodynamic stability and less pain at the site of injection compared to propofol. Hence, it may be a better induction agent in daycare surgeries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
