Summary Background: Mandatory postoperative food intake has been shown to increase nausea and vomiting, and so postoperative fasting has become common practice even if patients request food or drink. Objective: We sought to investigate whether postoperative fasting reduces the incidence of postoperative vomiting in children when compared with a liberal regimen in which they are allowed to eat and drink upon request. Methods: One hundred forty‐seven children scheduled for outpatient surgery were randomized to one of two groups. After anesthesia, patients in the ‘fasting’ group were expected to fast for 6 h. The children in the ‘liberal’ group were allowed to eat and drink according to their own needs. The incidence of vomiting and the children’s well‐being were recorded at several time points over a 24‐hour period. Parents were also asked to rate, on a scale of 0–6, how much their children were bothered by fasting, pain, and nausea/vomiting. Results: Age (4.8 ± 2.6 years), weight (20 ± 9 kg) and gender (73% boys) were comparable between the groups. The incidence of vomiting was 15% in the liberal and 22% in the fasting group ( P = 0.39) and, between 1 and 12 h after extubation, children in the liberal group were significantly happier ( P < 0.001). Children in the liberal group were significantly less bothered by their pain than those in the fasting group ( P < 0.001). Conclusion: Postoperative fasting did not reduce the incidence of vomiting after general anesthesia in children when compared with a liberal regimen. Furthermore, the ability to eat and drink at will decrease the bothersome aspects of pain and lead to happier patients.
