Major craniotomy surgery causes a significant blood glucose increase, particularly in younger patients. Adrenaline use during scalp infiltration and incision elevates blood glucose levels.

Elective major craniotomy is a complex surgical procedure.
Understanding perioperative metabolic changes is crucial for patient management.
Purpose of the Study:
To investigate blood glucose level fluctuations during elective major craniotomy.
To identify factors influencing hyperglycemic responses in these patients.
Main Methods:
Prospective study of 40 patients undergoing elective major craniotomy.
Monitoring blood glucose levels at different surgical stages.
Analyzing the impact of patient demographics and perioperative factors.
Main Results:
A significant hyperglycemic response was observed post-scalp infiltration with adrenaline and incision (0.5 mmol/l), and during continued surgery (0.9 mmol/l).
Patients aged 50 and under exhibited a more pronounced rise in blood glucose compared to older patients (0.8 vs. 0.4 mmol/l, p < 0.01).
Preoperative high-dose steroid therapy, sex, obesity, family history of diabetes, starvation duration, body temperature, anesthetic technique, induced hypotension, and blood loss did not significantly alter blood glucose changes.
Conclusions:
Elective major craniotomy, especially with adrenaline use, induces significant hyperglycemia.
Younger patients demonstrate a heightened hyperglycemic response during this surgical procedure.
Several common perioperative factors do not appear to influence these glucose level changes.
