Enhanced recovery after surgery strategy to shorten perioperative fasting in children undergoing non-gastrointestinal surgery: A prospective study.

BACKGROUND

Enhanced recovery after surgery strategies are increasingly implemented to improve the management of surgical patients.

AIM

To evaluate the effects of new perioperative fasting protocols in children ≥ 3 mo of age undergoing non-gastrointestinal surgery.

METHODS

This prospective pilot study included children ≥ 3 mo of age undergoing non-gastrointestinal surgery at the Children's Hospital (Zhejiang University School of Medicine) from January 2020 to June 2020. The children were divided into either a conventional group or an ERAS group according to whether they had been enrolled before or after the implementation of the new perioperative fasting strategy. The children in the conventional group were fasted using conventional strategies, while those in the ERAS group were given individualized fasting protocols preoperatively (6-h fasting for infant formula/non-human milk/solids, 4-h fasting for breast milk, and clear fluids allowed within 2 h of surgery) and postoperatively (food permitted from 1 h after surgery). Pre-operative and postoperative fasting times, pre-operative blood glucose, the incidence of postoperative thirst and hunger, the incidence of perioperative vomiting and aspiration, and the degree of satisfaction were evaluated.

RESULTS

The study included 303 patients (151 in the conventional group and 152 in the ERAS group). Compared with the conventional group, the ERAS group had a shorter pre-operative food fasting time [11.92 (4.00, 19.33) 13.00 (6.00, 20.28) h, < 0.001), shorter preoperative liquid fasting time [3.00 (2.00, 7.50) 12.00 (3.00, 20.28) h, < 0.001], higher preoperative blood glucose level [5.6 (4.2, 8.2) 5.1 (4.0, 7.4) mmol/L, < 0.001], lower incidence of thirst (74.5% 15.3%, < 0.001), shorter time to postoperative feeding [1.17 (0.33, 6.83) 6.00 (5.40, 9.20), < 0.001], and greater satisfaction [7 (0, 10) 8 (5, 10), < 0.001]. No children experienced perioperative aspiration. The incidences of hunger, perioperative vomiting, and fever were not significantly different between the two groups.

CONCLUSION

Optimizing fasting and clear fluid drinking before non-gastrointestinal surgery in children ≥ 3 mo of age is possible. It is safe and feasible to start early eating after evaluating the recovery from anesthesia and the swallowing function.
