Background:
Response to the surgical stress is an involuntary response to metabolic, autonomic as well as hormonal changes that leads to heart rate and blood pressure fluctuations.
Objectives:
This study aimed to investigate the effect of general versus spinal anesthesia on blood sugar level and hemodynamic changes in patients undergoing curettage surgery.
Patients And Methods:
In this randomized clinical trial, 50 patients who were candidate for elective curettage surgery were divided into two groups of general (n = 25) and spinal (n = 25) anesthesia. In both groups, blood glucose level was evaluated 10 minutes before, 20 and 60 minutes after initiation of anesthesia. Also, heart rate and mean arterial blood pressure were evaluated at 10 minutes before, 10, 20, 30, 40, 50 and 60 minutes after intiation of anesthesia.
Results:
There was not significantly difference between blood glucose level of both groups during 10 minutes before, 20 and 60 minutes after the intiation of anesthesia. Heart rate changes in the general and spinal groups compared to the baseline level were decreased up to maximum12.5% and 14.5%, respectively. The mean arterial pressure changes in the general and spinal groups compared to the baseline level were decreased up to maximum 5.4% and 8%, respectively.
Conclusions:
Blood glucose and hemodynamic changes caused by surgical stress were not significantly different between two groups.
