Abstract
Abstract Introduction Preoperative carbohydrate loading (PCL), part of Enhanced Recovery After Surgery (ERAS) protocols, involves giving carbohydrate-rich liquids before surgery instead of traditional fasting. It improves glucose control, reduces insulin resistance, and enhances patient comfort. Methods A comprehensive scoping review was conducted using databases such as PubMed, CINAHL, EMBASE, Cochrane Library, Scopus, and Web of Science, focusing on studies from 2017 to 2024. Primary, English-language clinical trial involving pediatric patients were included without restrictions on surgical procedure, or outcomes. Data extraction was focused on sample sizes, PCL types, and perioperative outcomes. Results The scoping review examined 10 studies on PCL in pediatric surgery, covering various procedures with sample sizes ranging from 18 to 1200 participants. Most studies indicated metabolic benefits, with 7 out of 11 showing stabilized blood glucose and reduced hypoglycemia risk. Additionally, 5 studies associated PCL with reduced preoperative anxiety, agitation, and discomfort, including thirst and hunger. For stomach content, 5 studies showed PCL reduced gastric residual volume and improved pH. Postoperative findings were mixed: 4 studies found no significant difference in nausea and vomiting, while 2 suggested benefits. Length of hospital stay from 3 studies showed no clinical difference results. Conclusions PCL in pediatric surgery shows potential to stabilize blood glucose, reduce metabolic risks, and improve recovery. However, the evidence regarding outcomes such as length of hospital stay and postoperative complications remains inconsistent, indicating the need for further investigation.
