PurposeThe objective of this study was to demonstrate that the gastric cross-sectional area (CSA) in the right lateral decubitus position (RLDP) during a 2-h fasting period is not larger than that during a conventional 4-h fasting period prior to pediatric echocardiography.Methods93 patients aged under 3 years scheduled for echocardiography under sedation were enrolled and randomly allocated into two groups; 2-h fasting vs 4-h fasting. For group 4 h (n = 46), the patients were asked to be fasted for all types of liquid for more than 4 h, while group 2 h (n = 47) were asked to be fasted for all types of liquid for 2 h before echocardiography. Gastric ultrasound was performed before echocardiography, and CSARLDP was measured. We compared CSARLDP, incidence of at-risk stomach, fasting duration, and the incidence of major (pulmonary aspiration, aspiration pneumonia) and minor complications (nausea, retching, and vomiting, apnea, and bradycardia) between two groups.ResultsThe mean difference of CSARLDP (group 2 h-group 4 h) was 0.49 (- 0.18 to 1.17) cm2, and it was within the non-inferiority margin (Δ = 2.1 cm2). There was no difference in the incidence of at-risk stomach (P = 0.514). There was no significant difference in the incidence of major and minor complications between the two groups.ConclusionTwo-hour fasting in pediatric patients who need an echocardiography did not increase major and minor complications and CSA significantly.© 2024.
