Comparison of blood sugar fluctuations in non-diabetic patients during orthopedic surgery in general anesthesia and spinal anesthesia

Surgical stress causes the transmission of a series of neurological and hormonal messages from the site of injury to the control centers, which causes physiological reactions. One of the metabolic responses to surgical stress is changes in serum glucose levels of patients undergoing surgery.

In this cohort study, 60 patients with anesthesia classes 1 and 2 underwent orthopedic surgery under general anesthesia and spinal anesthesia. Patients were divided into 2 groups: general anesthesia and spinal anesthesia. A glucometer was used to measure patients' blood sugar.

A total of 60 patients underwent orthopedic surgery under general anesthesia and spinal anesthesia. The spinal anesthesia and general anesthesia groups were similar in terms of gender, age, weight, and fluid intake. Mean BS showed no significant difference between spinal anesthesia and general anesthesia groups in preoperative times, after spinal anesthesia or general anesthesia, at 30 minutes and 60 minutes postoperatively and in recovery (p> 0.05). . Intra-group comparisons with analysis of variance with repeated measures showed that the mean trend of BS at the time of the study was significant only in the spinal anesthesia group (p = 0.006). The mean trend of BS in the spinal anesthesia group was reduced in the postoperative period compared to the preoperative period.

Considering the importance of regulating blood sugar around surgery, the present study preferred spinal anesthesia to control the patient's blood sugar to some extent over general anesthesia; but confirmation of this finding requires more detailed studies.
