Abstract
BACKGROUND Guidelines recommend a clear liquid fasting time of 2 h before surgery, which is often exceeded, leading to adverse reactions (ARs) such as discomfort, thirst, and dehydration. We assessed the gastric contents and ARs after oral glucose water administration 1 h prior to surgery in children with cyanotic congenital heart disease (CCHD). MATERIAL AND METHODS This was a non-inferiority randomized controlled trial of children with CCHD enrolled at the Fujian Medical University Union Hospital from 09/2014 to 05/2017 and randomized to receive oral glucose water (10 g of glucose in 100 ml of warm water, 5 ml/kg) 2 h (2-h group, n=174) or 1 h (1-h group, n=170) before surgery. The primary endpoint was gastric volume. Secondary endpoints included pH of gastric content, preoperative blood glucose, and risk factors for aspiration pneumonia. Pre- and intraoperative ARs were recorded. RESULTS The 1-h group showed smaller gastric content volumes (0.34±0.35 (95% CI: 0.29-0.39) vs. 0.43±0.33 (95% CI: 0.38-0.48) ml/kg, t=2.55, P<0.05) and higher blood glucose (6.21±0.78 (95% CI: 6.09-6.33) vs. 5.59±1.11 (95% CI: 5.43-5.76) mmol/L, t=-5.91, P<0.001). The 95% confidence interval of the volume difference between the 2 groups was 0.017-0.163, the upper limit value was 0.163
