Background
Critically ill children have a high prevalence of malnutrition. Children with acute kidney injury experience high rates of protein debt. Previous research has indicated that protein provision is positively associated with survival.
Methods
This was a prospective observational study of all patients receiving CRRT for greater than 48 h at our tertiary care institution. Patients with inborn errors of metabolism were excluded. Data collection included energy, protein, and fluid volume intakes, anthropometrics, feeding modality, and route of nutrition intake.
Results
Forty-one patients 9 ± 6.8 years of age, 66% male, received CRRT over a 10-month time period. CRRT treatment was 17.3 ± 25 days. Forty-one percent were malnourished via anthropometric criteria at CRRT start. Median protein delivery was 2 g/kg/day (IQR 1.4–2.5). Fifty-one percent received a combination of parenteral nutrition (PN) and enteral/oral feedings (EN), 34% received only PN, and 12% received only EN. Percentage of time meeting protein goals by modality was 27.6%, 34.6%, and 65.3% for those patients receiving solely EN, PN, and EN + PN combination, respectively. When weaned to only EN support from combination PN + EN, the average percentage of time protein goals were met decreased to 20.5% (p < 0.01).
Conclusions
Without PN, patients on enteral/oral nutrition support fail to meet appropriate protein prescription. Transition of parenteral to enteral feeds was identified as a period of nutritional risk in children receiving CRRT.
