[Clinical effect of feeding with calorie-enriched formula in children with ventricular septal defect and severe pneumonia].

OBJECTIVE

To study the effect of different energy feeding patterns on the nutritional status, clinical course, and outcome of children with congenital heart disease (CHD) and severe pneumonia.

METHODS

A total of 43 malnourished infants, aged <6 months, who were diagnosed with ventricular septal defect and severe pneumonia and underwent surgical operation from January 1 to December 30, 2017 were enrolled. They were randomly divided into an observation group with 21 infants and a control group with 22 infants. The infants in the observation group were given calorie-enriched formula milk powder (100 kcal/100 mL) after surgery, and those in the control group were given formula milk powder with normal calories (67 kcal/100 mL). The two groups were observed for 3 months to record physical measurements, laboratory markers and nutritional risk screening results. Nutritional status was evaluated for all infants. The two groups were compared in terms of prognosis and adverse events.

RESULTS

There were no significant differences between the two groups in physical measurements, laboratory markers, nutritional assessment and nutritional risk screening results on admission (P>0.05). At discharge and 1 and 3 months after surgery, the control group had significantly higher degree of malnutrition and level of nutritional risk than the observation group (P<0.05). The analysis of variance with repeated measures showed significant differences in body weight, upper arm circumference, weight-for-age Z-score, height-for-age Z-score, weight-for-height Z-score, and albumin level at different time points and between different groups, and there was an interaction between group factors and time factors (P<0.05). Compared with the control group, the observation group had a significantly lower average daily intake of fluid, a significantly higher average daily intake of energy, and a significantly lower incidence rate of insufficient feeding during hospitalization (P<0.05). Compared with the control group, the observation group had significantly shorter length of hospital stay, duration of mechanical ventilation, and duration of postoperative pyrexia, as well as significantly lower hospital costs (P<0.05). No significant adverse reactions were observed in either group.

CONCLUSIONS

An appropriate increase in postoperative energy supply for children with CHD can improve the status of malnutrition and clinical outcome.
