Background: Hyperglycemia and inflammatory conditions due to surgical stress response in conventional brain tumor resection can increase the morbidity and mortality of neurosurgery patients. Enhanced recovery after surgery (ERAS) protocol has been widely used in various types of surgery, but data on the neurosurgery are still limited. The aim of this study was to analyze the role of preoperative oral glucose administration in attenuating surgical stress response in patients undergoing brain tumor resection. Materials and Methods: Thirty-four elective craniotomy brain tumor resection patients underwent a double-blind, randomized controlled trial. Patients were divided into two groups: one group that received oral carbohydrate (CHO; maltodextrin 12.5% 50 g in 400 ml water) 2 h preoperatively and a control group that only received water. Blood glucose level and neutrophil-lymphocyte ratio (NLR) were obtained preoperatively, before induction, and 6 h and 24 h postoperatively. Results: Blood glucose was better in the CHO group at 6 h (117.18 ± 16.25 mg/dl vs. 154.88 ± 28.22 mg/dl, P < .001) and 24 h (118.05 ± 13.89 mg/dl vs. 153.76 ± 34.81 mg/dl, P < .001) postoperatively compared to that in the control group. NLR in the CHO group showed a lower value compared to that in the control group at 6 h (8.21 ± 6.20 vs. 15.47 ± 6.76, P < .001) and 24 h (9.43 ± 7.35 vs. 20.04 ± 10.99, P < .001) postoperatively. Conclusion: Preoperative oral glucose administration can help reduce the stress response in brain tumor resection by maintaining blood glucose level and attenuating the increase of NLR postoperatively better than in routine preoperative fasting.
