Abstract
Aim of Study: Surgical stress produces metabolic as well as hormonal changes and these effects are even more pronounced in diabetics. Glycemic control is a very challenging task during surgical stress especially in diabetics. The aim of our study is to compare the effects of spinal and general anaesthesia on blood glucose level in diabetic patients.
Material and Methods: Forty diabetic patients controlled on oral hypoglycemic agent or insulin posted for elective surgical procedures were randomly divided into two groups I & II. Group I patients were given general anaesthesia and group II received spinal anaesthesia. In both the groups, blood glucose were recorded at pre-operative period, 30 minutes intra-operative, and 60 minutes intra-operative and at 20 minutes post-operative. The results were compared and studied statistically.
Results: The mean glucose level of group I (GA) and group II (SA) were comparable at pre-operative period. The values at 30 minutes, 60 minute intra-operative and 20 minute post-operative of group I (GA) are 127.45 + 13.69, 141.50 + 12.57 and 150.30 + 13.18 respectively. In group II the values are 120.50 + 9.82 at 30 minute and 124.05 + 10.56 at 60 minute intra-operative. At 20 minute post-operative it was 125.00 + 11.11. When these values are compared, group I (GA) patients showed a significant increase in blood glucose level than group II (SA) patients at all the time intervals, p (30 min) = 0.073, p (60 min) = 0.000, p (20 min post-operative) = 0.000.
Conclusion: The increase in blood glucose level during surgical stress in diabetics is less under spinal anaesthesia than under general anaesthesia.
