Postoperative Recovery Quality According to Preoperative Fasting Time in Pediatric Patients Undergoing Nuss Operation

Plain-language summary

Preoperative fasting is intended to lower the amount of gastric contents in order to decrease the incidence of aspiration associated with endotracheal intubation. However, recent studies show that longer fasting time does not reduce aspiration associated complications. Especially in pediatric patients, long fasting time increases patients' unpleasantness and therefore increases postoperative recovery quality. It also induces hypoglycemia. In many studies, ingesting clear liquids 2 hours up to general anesthesia decreases gastric contents and therefore the incidence of aspiration pneumonia, postoperative nausea and vomiting. Therefore anesthesiologist associations in the US and Europe recommend to drink small amount of clear liquid (water) up to 2 hours before the surgery. Nuss bar operation, or repair surgery of pectus excavatum is mostly done in pediatric patients. The procedure itself is very painful, requiring paramount amount of analgesics. Use of opioid analgesics increases postoperative nausea and vomiting. In this study, our aim is to evaluate preoperative fasting time and how preoperative supplement of clear liquid affects the quality of recovery postoperatively.
