Effect of preoperative feeding on gastric emptying following spinal anesthesia: A randomized controlled trial. An RCT comparing a light breakfast consumed less than 4 h before a procedure with overnight fasting reports equivocal findings for gastric volume and pH levels for adults (Category A3-E evidence).47 A second RCT reports equivocal findings when a light breakfast is allowed at 4 h compared with 6 h before a cesarean section (Category A3-E evidence), although a significant reduction in maternal and neonatal blood glucose levels was reported when fasting was extended beyond 6 h (Category A3-H evidence).48 Nonrandomized comparative studies for children given nonhuman milk 4 h or less before a procedure versus children fasted for more than 4 h report equivocal findings for gastric volume and pH (Category B1-E evidence).4951 One nonrandomized study indicated that fasting for more than 8 h may be associated with significantly lower blood glucose levels (Category B1-H evidence).51 The literature is insufficient to evaluate the effect of the timing of ingestion of solids and nonhuman milk and the perioperative incidence of pulmonary aspiration or emesis/reflux.
