BACKGROUND
The incidence of postoperative nausea and vomiting (PONV) can be reduced by dexamethasone. Single-dose administration may cause elevated blood glucose levels in obese adults. No data are available for children.
OBJECTIVE
The aim was to evaluate perioperative blood glucose changes related to body weight in children who received dexamethasone.
METHODS
This prospective observational study included 62 children. All patients received total intravenous anesthesia and a single dose of dexamethasone (0.15 mg/kg, maximum 8 mg). Blood glucose levels were measured up to 6 h. Standard deviation scores (SDS) were calculated using age- and gender-specific body mass index (BMI) percentiles, p<0.05.
RESULTS
A total of 62 children (11.5±2.9 years, median SDS 0.43, 29% overweight/obese) were included. Blood glucose levels increased from 5.52±0.52 to 6.74±0.84 mmol/L 6 h after dexamethasone without correlation to the BMI-SDS.
CONCLUSIONS
This study showed an increase of perioperative blood glucose (normoglycemic ranges) after single dose of dexamethasone, but no BMI-dependent effect was observed in children. Therefore, low-dose dexamethasone may be used in obese children for PONV prophylaxis.
