Comparison of dose requirement of propofol with and without bispectral monitoring in patients undergoing spinal epidural anaesthesia: An institutional based study

Introduction: Sedative protocols are a topic of current research, especially for establishment of extensive monitoring systems for sedative agents. Bispectral index (BIS) is one of the main indicators for measuring the anaesthesia depth. Hence; present study was planned to comparatively assess the dose requirement of propofol with and without bispectral monitoring in patients scheduled to undergo spinal epidural anaesthesia. Materials and Methods: We planned the present research to comparatively assess the dose requirement of propofol with and without bispectral monitoring in subjects scheduled to undergo spinal epidural anaesthesia. For the present study, we evaluated a total of 60 patients and broadly divided them into group 1 and group 2, based on the absence and presence of BIS monitoring respectively. We maintained and compiled the complete demographic, clinical and anaesthetic data of all the patients and analyzed the results by SPSS software. Results: While comparing the average time needed for reaching the adequate level of sedation in between the two study groups, significant results were obtained. We also obtained significant results while comparing the average recovery time in between subjects of both the study groups. Conclusion: For assessing the level of sedation in regional anaesthesia cases, BIS monitoring should be done. Keywords: Bispectral monitoring, Propofol, Spinal anaesthesia.
