Ultrasound Evaluation of Gastric Emptying Time in Healthy Term Neonates after Formula Feeding

Background The current American Society of Anesthesiologists fasting guideline for formula-fed infants in the periprocedural setting is 6 h. Prolonged very young associated with an increased risk hypoglycemia and dehydration as well patient discomfort patient/parental dissatisfaction. This study aimed to determine time gastric emptying healthy neonates after formula feeding by serially evaluating antrum ultrasound. authors hypothesized that times are significantly shorter than h recommendation. Methods After institutional review board approval written informed parental consent, ultrasound examination was performed full-term before at 15-min intervals until return baseline. Ultrasound images were measured obtain cross-sectional areas, which then used estimate antral volumes. Results Forty-six 48 recruited included final analysis. Gastric ranged from 45 150 min averaged 92.9 (95% CI, 80.2 105.7 min; 99% 76.0 109.8 min) overall group. No significant differences found between male female (male: mean, 93.3 [95% 82.4 104.2 min]; female: 92.6 82.0 103.2 P = 0.930) or those delivered vaginal versus cesarean routes (vaginal: 93.9 81.7 106.1 cesarean: 92.2 82.5 101.9 0.819). Conclusions These results demonstrate substantially less formula-fed, term neonates. Editor’s Perspective What We Already Know about Topic Article Tells Us That Is New
