Effect of high-energy and/or high-protein feeding in children with congenital heart disease after cardiac surgery: a systematic review and meta-analysis.

Abstract

High-energy or high-protein feeding offers a promising approach to improving malnutrition in children after congenital heart surgery. However, the effect of high-energy or high-protein feeding in this population has not yet been systematically reviewed. Therefore, we aimed to assess the safety and effectiveness of high-energy or high-protein feeding in children after congenital heart surgery. Five electronic databases (PubMed, Embase, CENTRAL, CINAHL, and Scopus) were searched from inception to April 23, 2022. After screening the literature according to inclusion and exclusion criteria, a risk of bias assessment was performed using version 2 of the Cochrane risk-of-bias tool for randomized trials, and the certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations system. Finally, the random effects model was used to perform a meta-analysis of all data. A total of 609 subjects from 9 studies were included for qualitative analysis, and meta-analyses were performed on data from 8 of these studies. The results showed that high-energy and/or high-protein feeding did not increase feeding intolerance (RR = 1.09, 95% CI: 0.80, 1.48) or fluid intake (MD =  - 12.50 ml/kg/d, 95% CI: - 36.10, 11.10); however, the intervention was beneficial in increasing weight (MD = 0.5 kg, 95% CI: 0.23, 0.77) and reducing the duration of mechanical ventilation (MD =  - 17.45 h, 95% CI: - 27.30, - 7.60), intensive care unit (ICU) stay (MD =  - 1.45 days, 95% CI: - 2.36, - 0.54) and hospital stay (MD =  - 2.82 days, 95% CI: - 5.22, - 0.43). However, high-energy and/or protein feeding did not reduce the infection rate (RR = 0.68, 95% CI: 0.25, 1.87) or mortality (RR = 1.50, 95% CI: 0.47, 4.82).

CONCLUSION:

The certainty of the evidence was graded as moderate to high, which suggests that high-energy and/or high-protein feeding may be safe in children after congenital heart surgery. Furthermore, this intervention improves nutrition and reduces the duration of mechanical ventilation, length of ICU stay, and length of hospital stay. However, the overall conclusion of this meta-analysis will need to be confirmed in a cohort of patients with different cardiac physiologies.

WHAT IS KNOWN:

• Malnutrition is highly prevalent in children with congenital heart disease (CHD) and can negatively affect the prognosis of these children. • High-energy and/or high-protein feeding can improve nutrition status and facilitate recovery; however, evidence on its safety and efficacy is lacking.

WHAT IS NEW:

• Pooled data suggest that high-energy and/or high-protein feeding does not increase fluid intake or feeding intolerance in children with CHD. • High-energy and/or high-protein feeding may reduce the duration of mechanical ventilation, length of intensive care unit stay, and length of hospital stay.
