Abstract

BackgroundNausea and vomiting are common causes for prolonged postoperative length of hospital stay (LOS) in children. A preoperative carbohydrate load may reduce postoperative nausea and vomiting by improving the perioperative metabolic state. The aim of this study was to determine if a preoperative carbohydrate-containing drink would lead to an improvement in the perioperative metabolic state and consequently reduce the incidence of postoperative nausea, vomiting and LOS in children undergoing day-case surgical procedures. MethodRandomised, double-blind, placebo-controlled trial involving children aged 4 to 16-years undergoing day-case surgical procedures. Patients were randomised to receive a carbohydrate-containing drink or a placebo. During the induction of anaesthesia, a venous blood gas, and blood glucose and ketone levels were measured. Postoperatively, the incidence of nausea, vomiting, and LOS were documented. Results120 patients were randomised with 119/120 (99.2%) undergoing analysis. Blood glucose level was higher in the carbohydrate group; 5.4 mmol/L [3.3–9.4] versus 4.9 mmol/L [3.6–6.5] (p = 0.01). Blood ketone level was lower in the carbohydrate group; 0.2 mmol/L versus 0.3 mmol/L (p = 0.003). The incidence of nausea and vomiting was not different (p > 0.9 and p = 0.8, respectively). LOS in the carbohydrate group was 26 min shorter than the placebo group (p = 0.02). ConclusionAlthough a preoperative carbohydrate load may provide a more stable metabolic state at the induction of anaesthesia, we did not find a reduction in postoperative nausea and vomiting. A preoperative carbohydrate load has also minimal effects on the postoperative LOS. Type of studyRandomised clinical trial. Level of evidenceI.
