Introperative blood glucose concentration (BGC) abnormalities are associated with increased perioperative morbidity and mortality (1-4). Severe intraoperative hyperglycemia (BGC ≥ 200 mg/dl) in patients undergoing craniotomy for urgent/emergent craniotomy after traumatic brain injury (TBI) complicates 15% of the cases and is associated with higher in-hospital mortality. Intraoperative use of dexamethasone during craniotomy is also known to induce an increase in BGC.

The importance of BGC in neurosurgical patients is witnessed by the effects of tight blood glucose control on incidence of infections and neurological outcome . Currently available evidence suggest that, in neurosurgical patients, perioperative BGC values should be within the 80-180 mg/dl range .

Data on the prevalence of severe intraoperative hyper (BGC >180 mg/dl) and hypoglycemia (BGC <80 mg/dl) in patients undergoing craniotomy for supra or infratentorial surgery as elective or emergency procedure are lacking as it is not known whether in these patients intraoperative severe hyperglycemia relates to an increased incidence of postoperative infections is unknown.

Aim of this prospective observational study -in patients undergoing craniotomy for supra or infratentorial surgery as elective or emergency procedure- was to test the hypothesis that severe intraoperative hyperglycemia (BGC ≥180mg/dl) is associated with an increased incidence of infections within the first postoperative week (pneumonia, sepsis, urinary and wound and cerebral infections). We also recorded the prevalence of severe intraoperative hyper and hypoglycemia (BGC<80 mg/dl) in recruited patients.
