High-Energy Enteral Nutrition in Infants After Complex Congenital Heart Surgery

ABSTRACT:

Background

Malnutrition is common in complex congenital heart disease (CCHD). The purpose of this study was to compare the safety and efficacy of early initiation of high-energy enteral nutrition (EN) with regular energy EN in infants after surgery for CCHD.

Methods

This is a subgroup analysis of a randomized controlled trial (RCT) which was conducted in the cardiac intensive care unit (CICU) of the largest pediatric heart center in China. Eighty children with CCHD after surgery were from two groups, the intervention group (n = 40) was given high-energy EN and the control group (n = 40) was given regular energy EN. We analyzed the effects of the two interventions on outcomes such as caloric attainment rate, gastrointestinal intolerance, duration of mechanical ventilation, and anthropometry at discharge.

Results

There was no difference in the daily milk intake between the two groups, but the calorie intake (50.2 vs. 33.4, P < 0.001), protein intake (1.1 vs. 0.9, P < 0.001) and caloric attainment rate were higher in the intervention group (77.5 vs. 45.0%, P = 0.003). In addition, the incidence of pneumonia (P = 0.003) and duration of mechanical ventilation (P = 0.008) were less in the intervention group, and biceps circumference and triceps skinfold thickness at hospital discharge were greater than those in the control group (P < 0.001). We have not found statistical differences in gastrointestinal intolerance, glycemic fluctuations, incidence of pressure ulcers, length of CICU stay and postoperative hospital days between the two groups.

Conclusions

Early initiation of high-energy EN may be safe and effective in infants after complex cardiac surgery. Low doses high-energy EN did not increase gastrointestinal intolerance or glycemic fluctuations and also improved post-operative nutrition by increasing caloric and protein intake without increasing fluid intake.

Project description:AimWe explored the association between preoperative anthropometry and biochemistry, and postoperative outcomes in infants with CHD after cardiac surgery, as infants with congenital heart disease (CHD) often have feeding difficulties and malnutrition.MethodologyThis was a retrospective review of infants (≤ 1-year-old) who underwent congenital heart surgery. Preoperative anthropometryin terms of preoperative weight-for-age z-score (WAZ), length-for-age z-score (LAZ), as well as preoperative serum albumin and hemoglobin concentrations, were evaluated against 6-month mortality, and morbidity outcomes including postoperative complications, vasoactive inotrope score, duration of mechanical ventilation, length of stay in the pediatric intensive care unit and in hospital, using the logistic regression or median regression models accounting for infant-level clustering.ResultsOne hundred and ninety-nine operations were performed in 167 infants. Mean gestational age at birth was 38.0 (SD 2.2) weeks (range 26 to 41 weeks). Thirty (18.0%) infants were born preterm (<37 weeks). The commonest acyanotic and cyanotic lesions were ventricular septal defect (26.3%, 44/167), and tetralogy of Fallot (13.8%, 23/167), respectively. Mean age at cardiac surgery was 94 (SD 95) days. Feeding difficulties, including increased work of breathing during feeding, diaphoresis, choking or coughing during feeding, and inability to complete feeds, was present in 54.3% (108/199) of infants prior to surgery, of which 21.6% (43/199) required tube feeding. The mean preoperative WAZ was-1.31 (SD 1.79). Logistic regression models showed that low preoperative WAZ was associated with increased risk of postoperative complications (odds ratio 1.82; p = 0.02), and 6-month mortality (odds ratio 2.38; p = 0.008) following CHD surgery. There was no meaningful association between the other preoperative variables and other outcomes.ConclusionMore than 50% of infants with CHD undergoing cardiac surgery within the first year of life have feeding difficulties, of which 22% require to be tube-fed. Low preoperative WAZ is associated with increased postoperative complications and 6-month mortality.
