Brief Summary

*Background:* Perioperative pulmonary aspirationrisk increases with increased preoperative gastric volume; hence traditionally,patients are kept fasted overnight before surgery. Current guidelines recommend2-hours clear fluids fasting prior to anaesthesia. However, emerging evidencefavours allowing 3 mL/kg clear fluids up to 1-hour before anaesthesia. Wecompared the gastric volume and gastric emptying time after ingestion of 3mL/kg and 5 mL/kg of clear fluids.

*Methods:* Forty-four children were enrolledafter getting informed and written consent from parents. On the day of surgery,baseline gastric volume was estimated using ultrasound and patients wererandomly allocated in to two groups of equal number i.e. Group 3 and Group 5(patients received 3 mL/kg and 5 mL/kg 5% Dextrose respectively). Repeatedgastric ultrasound was done at every five-minutes interval until the gastricvolume reached at baseline. The primary objective of the study was to comparegastric volume and gastric emptying time while secondary objectives wereoccurrence of PONV, occurrence of irritability and parent’s satisfaction.

*Results:* The demographic profile,preoperative fasting duration and baseline gastric volume was comparablebetween groups. In both groups, compared to baseline the gastric volumeincreased significantly following fluid ingestion and then decreased exponentiallyto reach at baseline within 1-hour. The median (IQR) gastric emptying time andemptying t1/2 (minutes) in group 3 was 35.0 (28.75, 40.0) and 17.00(15.73, 21.50) respectively while in group 5 it was 40.0 (28.75, 45.0) and18.55 (15.98, 21.98) respectively (p=0.16 and p=0.44 respectively).  The occurrence of nausea, vomiting andirritability as well as parent satisfaction were comparable between the groups(p>0.05).

*Conclusion:* As the gastric volume returned tobaseline within 1-hour even after ingesting 5mL/kg clear fluids, the preoperative fasting time can be reduced to 1-hour and childrencan be safely allowed to drink up to 5 mL/kg clear fluids.
