Effect of energy-enriched formula for catch-up growth in malnourished infants after congenital heart disease surgery / 中华临床营养杂志

ABSTRACT

Objective To investigate the efficacy and safety of enriched-calorie formula in post-operative infants with congenital heart disease and malnutrition.Methods All malnourished infants less than 6 months diagnosed congenital heart disease ventricular septal defect and had undergone surgery in Guangzhou Women and Children`s Medical Center from December 1,2014 to May 30,2015 were included in this study.All cases were randomly divided into intervention group(energy-enriched formula,intervention group)and control group(standard formula,control group)for enteral nutrition intervention and observed for 3 months.Body mass,body length,upper arm circumference,blood prealbumin(PA),retinol binding protein(RBP),and B-terminal pro-brain natriuretic peptide(NT-proBNP)were measured before and after ICU,after discharge,and 1 month and 3 months after operation.Results Fifty-one cases were in intervention group and 50 cases in control group,respectively.There were no significant differences in body mass,body length,arm circumference,PA,RBP,mean enteral nutrition starting time,mechanical ventilation time,length of ICU stay,hospitalization time,and average fluid intake between the two groups(all P>0.05).The average caloric intake in intervention group was significantly higher than in control group [(437.24±6.68)kJ vs.(312.43±86.22)kJ,P=0.001].There was no significant difference in NT-proBNP,PA,and RBP at different time points between the two groups(all P>0.05).The improvement of nutrition in intervention group was significantly higher than that in control group at 1 month(25.0％vs.4.9％,P=0.011)and 3 months(64.1％vs.15.7％,P<0.001)after operation.Body mass increased in intervention group [(0.067±0.348)kg] compared with that in control group,and decreased [(0.125±0.425)kg] in control group(P=0.015).Body weight[(5.46±1.36)kg vs.(4.80±1.01)kg,P=0.008],weight for age Z score(WAZ)(-2.79±1.28 vs.-3.75±1.27,P<0.001),and height for weight Z score(WHZ)(-2.47±1.43 vs.-3.62±1.77,P=0.001)one month after surgery were significantly higher than those before operation.Body weight [(6.78±1.42)kg vs.(5.72±1.01)kg,P<0.001] arm circumference [(12.80±1.17)cm vs.(12.00±0.90)cm,P<0.001],WAZ(-1.60±1.17 vs.-3.10±1.40,P<0.001),height for age Z score(HAZ)(-1.41±1.63 vs.-2.10±1.41,P=0.034),and WHZ(-0.86±1.31 vs.-2.59±2.13,P<0.001)of the two groups at 3 months postoperative were significantly higher than those before operation,and the growth rate of intervention group was faster than control group.There were no significant adverse reactions in both groups.Conclusion Calorie-enriched formula powder can help malnourished infants to catch up after congenital heart disease surgery.
