Meta AnalysisEffects of preoperative oral carbohydrate on postoperative discomfort in patients undergoing elective surgery: a meta-analysis of randomized controlled trials.
Fasting is a standard preoperative procedure performed to prevent vomiting and pulmonary aspiration during anaesthesia and surgery. However, fasting can cause postoperative physical and psychological discomfort. Intake of oral carbohydrate (CHO) may mimic the intake of food, which prevents postoperative discomfort. We conducted a meta-analysis to evaluate the effect and safety of preoperative oral CHO in adult surgical patients. ⋯ Preoperative CHO can alleviate patient's discomfort without safety concerns. Surgeons and anaesthesiologists should strongly promote preoperative CHO as a strategy to enhance recovery after surgery protocols.
