Obejectives: Children with congenital heart disease (CHD) are at high risk for malnutrition, and the body composition changes obtained through bioelectrical impedance analysis (BIA) could be a sensitive index for the nutritional evaluation of CHD children during the perioperative period. Methods: Seventy-five children with CHD (37 male, 38 female, average age 4.53±1.69ys) were enrolled in the study. Their body composition and phase angel (PA) were measured via BIA one day before, one day after and seven days after open heart surgery respectively. Seventy-five gender and age matched health controls were also recruited. Results: The PA one day after surgery was significantly lower than that one day before surgery and returned to the preoperative level seven days after surgery. However, a repeated-measures analysis of variance (ANOVA) showed that the changes in the body weight, fat mass, free-fat mass, and body cell mass over time were not significant, whereas the changes in the PA over time were significant. The repeated-measures ANOVA indicated that changes in the total body water, edema index, and intracellular water over time were not significant, but the changes in the extracellular water were significantly. Conclusions: The PA might be a sensitive index for the nutritional evaluation of CHD children during the perioperative period. The conditional implementation of BIA has been proposed for the accurate evaluation of the nutritional status of CHD children, which would allow individualized nutritional support and thus improvement of the nutritional conditions and clinical outcomes of CHD children.
