Effect of Low Dose Dexamethasone on Blood Glucose Concentration in Patients Undergoing Craniotomy / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo evaluate the effect of low dose of dexamethasone on the blood glucose concentration in patients undergoing craniotomy. Methods20 consecutive patients undergoing craniotomy without a preexisting metabolic disorder were prospectively randomized into 1 of 2 groups Dexamethasone (group D, n=10) and Normal Saline (group S, n=10), who were given dexamethasone 10 mg intravenous bolus or a saline placebo preoperatively. Arterial glucose concentrations were measured immediately before and after treatment and hourly for 5 hours intraoperatively. ResultsThe arterial glucose concentration in group D increased significantly(F=3.133,P<0.05), while those in group S keep stable. Compared with group S, arterial glucose concentration in group D increased significantly 180 min after dosing(P<0.01). ConclusionIf dexamethasone is used during craniotomy, perioperative blood glucose level should be carefully monitored and controled.
