Use of Ultrasound for Body Composition in Assessment in Pediatric Patients: Are There Still Challenges?

TL;DR

This paper explores the use of ultrasound to assess muscle mass in hospitalized children and highlights the need for standardized protocols.

Contribution

The study identifies challenges in standardizing ultrasound-based muscle mass assessment in pediatric patients.

Findings

Muscle thickness reduction detected by ultrasound correlates with prolonged mechanical ventilation and poor nutrition in children.

All studies observed more than 10% muscle thickness reduction during hospitalization.

Current protocols for assessing muscle mass via ultrasound lack standardization and clear cut-off points.

Abstract

Patients who present nutritional risk upon hospital admission are more likely to have worse clinical outcomes. Evaluating muscle thickness with ultrasound is a predictor of muscle mass loss in pediatric patients. We reviewed the muscle mass loss detection through ultrasound to assess the body composition of pediatric patients. We found an association between muscle reduction, as detected by ultrasound, and the duration of mechanical ventilation, nutritional deficits in energy and protein intake, and the age-related skeletal muscle atrophy of the limbs. All studies reported a reduction in muscle thickness of more than 10% during hospitalization. There is a lack of standardization in muscle mass assessment protocols and established cut-off points in critically ill hospitalized children. Further studies are needed to establish an accurate and standardized analysis for monitoring muscle changes using ultrasound.
