%X OBJECTIVE: The 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.
METHODS: 93 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.
RESULTS: The 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.
CONCLUSIONS: Two-hour fasting in pediatric patients who need an echocardiography did not increase major and minor complications and CSA significantly.
