ENERGY EXPENDITURES OF INFANTS WITH VENTRICULAR SEPTAL DEFECTS

患有先天性心脏病的婴儿经常经历失败 茁壮成长。有几个因素被认为是造成增长的原因 这些婴儿的发育迟缓，包括静息代谢率增加， 体力活动中的能量消耗增加，而减少 营养摄入量。这项研究的目的是比较总的 3~4月龄中~大型婴儿的日能量消耗 室间隔缺损与健康对照婴儿室间隔缺损的顺序 以确定每天的总能量消耗是否增加 从左到右明显的先天性心脏病婴儿 调车。右心压，左向右分流的数量， 和室间隔缺损的大小将被测量以 评估这些因素与以下变化之间可能存在的关联 能源需求或失败的严重程度可能发生在 一组患有心脏病的婴儿。

Infants with congenital heart disease frequently experience failure to thrive. Several factors are thought to contribute to the growth retardation of these infants, including increased resting metabolic rate, increased energy expenditure in physical activity, and decreased nutritional intake. The purpose of this study is to compare the total daily energy expenditure of 3-4 month old infants with moderate to large ventricular septal defects with those of healthy control infants in order to determine if there is an increase in the total daily energy expenditure in infants with congenital heart disease with significant left-to-right shunting. The right heart pressures, quantity of the left-to-right shunt, and size of the ventricular septal defect will be measured in order to assess any possible association between these factors and variations in energy requirements or severity of failure to thrive that may occur in the group of infants with heart disease.
