Parenteral nutrition customization in pediatrics: A descriptive cohort study.

Abstract

Objectives: The main objective of this study was to analyze the reasons for customizing parenteral nutrition (PN) in pediatric patients admitted to a quaternary hospital.

Methods: We performed a descriptive cohort study on 264 hospitalized children receiving PN. Anthropometric, biochemical, and hospitalization data were collected from patient records. Unequivocal reasons for customizing PN were defined as situations precluding prescription of a standard adult/teenager PN and included renal and/or liver failure, energy-protein adequacy, and elevated mineral and triglyceride levels.

Results: A total of 264 patients, with a median age of 2.2 years (IQR: 0.3-9.0 years), comprising intensive care (n = 216; 81.8%) and malnourished (n = 91; 36.1%) patients, were evaluated. In the first 48 h, 87.9% (n = 232) of the sample required customized PN for energy-protein adequacy (210 of 232), maintained over subsequent days in most cases. Among patients requiring second individualization, mineral disturbance was the main reason observed, especially within the first 4 days of PN use (n = 21; 60%). Unequivocal reasons for customizing PN occurred in 97.4% (n = 226) of cases in the first 48 h; 96.2% (n = 177) of cases on the fourth day; and 90.1% (n = 92) of cases on the seventh day of PN use. An inverse correlation was found between weight/age z score and number of second individualizations (r = -0.222; P = 0.002).

Conclusion: Customized PN proved essential, especially for younger, malnourished, and intensive care patients. Investment in training a Nutritional Multidisciplinary Therapy Team and acquiring a specific electronic system for prescribing PN is suggested.
