Blood Glucose as a Prognostic Predictor of Traumatic Brain Injury in Patients That Underwent Surgical Intervention

Objective: Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide.This study investigated the prognostic value of the initial blood glucose levels in surgically treated patients with TBI.Methods: This prospective observational study included 90 patients with TBI who underwent surgery.Those with conditions affecting glucose metabolism, such as diabetes, were excluded.Blood glucose levels were measured on admission.Mortality and length of hospital stay were recorded, and correlations between glucose levels and outcomes were analyzed, including subgroup analyses according to TBI severity.Logistic regression was used to identify independent predictors and to control for confounding factors.Results: Mean initial blood glucose was 149.89 mg/dL.Overall, higher blood glucose levels were significantly correlated with longer hospital stay (r=0.320,p=0.002) and increased mortality (r=0.524,p
