Introduction: Diabetes Mellitus (DM) is a multisystem metabolic disorder. The techniques of anaesthesia, specifically the usage of general and regional anaesthesia can change (or) modify any residual insulin secretion and catabolic hormones secretion.
Aim: To compare and determine the perioperative and postoperative changes in the blood glucose, Blood Pressure (BP), Heart Rate (HR) and Visual Analog Scale (VAS) pain score among the diabetic patients under regional and general anaesthesia.
Materials and Methods: A retrospective study of 100 diabetic patients who had undergone surgeries under general and regional anaesthesia was performed. The patients were divided into two groups based on the type of anaesthesia used during surgery. Information pertaining to the level of blood glucose, BP and HR of the diabetic patients under general and regional anaesthesia were retrieved and analysed. Statistical analyses was performed to determine the significance of any differences observed between the two groups.
Results: The study revealed that the blood glucose level among the diabetic patients under general and regional anaesthesia was found to be higher in post surgery period when compared to the blood glucose level among the patients in pre surgery period under general and regional anaesthesia. The study also reported that the level of Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and HR among the diabetic patients during surgery under general and regional anaesthesia decreased when compared to the level of SBP among the patients at pre surgery under both general and regional anaesthesia. The level of the SBP post surgery under regional anaesthesia remained the same as pre surgery level. VAS pain score among the patients in general anaesthesia group was found to increase almost instantly after the completion of surgery while that among the regional anaesthesia group was found to increase only after the 3rd or 4th hour of post-surgery.
Conclusion: The study concludes that there was an increased intraoperative blood glucose fluctuation, alterations in the BP and HR level among the diabetic patients upon administration of both general and regional anaesthesia.
