Effect of Spinal Anesthesia versus General Anesthesia on Blood Glucose Concentration in Patients Undergoing Elective Cesarean Section Surgery: A Prospective Comparative Study

摘要

Background. This prospective study compared the blood glucose concentration with spinal anesthesia or general anesthesia in patients undergoing elective cesarean section surgery. Methods. In total, 58 pregnant women who underwent elective cesarean section surgery were included in this prospective comparative study. Group S (n?=?35) included patients who chose spinal anesthesia, and group G (n?=?23) included patients who chose general anesthesia. The patients were allocated to the groups upon patients’ preference. For the group G, the blood glucose concentration (BGC) was obtained 5?minutes before induction, T1, and 5?minutes after induction T2. For the group S, the BGC was obtained immediately before the injection of the local anesthetic agent T1 and 5?minutes after the complete block T2. For both groups, BGC was measured 5?minutes before the end of surgery T3 and 30?minutes after the end of surgery T4. For BGC measurements, we used a blood glucose monitoring system with a lancet device to prick the finger. Results. There was no statistically significant difference in the mean blood glucose concentration between the groups S and G in T1 (78.3?±?18.2 vs. 74.3?±?14.7, p0.05) and T2 (79.2?±?18.3 vs. 84.9?±?23.7, p0.05). The mean BGC was statistically significantly higher in group G in comparison to group S in the times 5?minutes before (80.2?±?18.1 vs. 108.4?±?16.7, p0.05) and 30?minutes after the end of surgery (80.9?±?17.7 vs. 121.1?±?17.4, p0.05). Conclusion. There is a much lower increase in blood glucose concentration under spinal anesthesia than under general anesthesia. It is reasonable to suggest that the blood sugar concentration must be intraoperatively monitored in patients undergoing general anesthesia.
