摘要

Purpose of Review

This review evaluates the role of point-of-care ultrasound (POCUS) in assessing diaphragmatic structure and function in children. It examines standardized imaging techniques, key sonographic indices, clinical applications across conditions, and limitations including measurement variability and scarce pediatric normative values.​

Recent Findings

Recent studies confirm diaphragmatic POCUS as a feasible, non-invasive bedside tool for respiratory evaluation in neonates and children. Indices such as diaphragmatic thickness (Tdi), thickening fraction (DTF), time to peak inspiratory amplitude (TIPA), and excursion (DE) aid in diagnosing dysfunction, predicting extubation success, and monitoring effort in neuromuscular disorders and acute pulmonary diseases. Age-related changes in measurements are evident, though methodological variations persist.

Summary

Diaphragmatic POCUS offers radiation-free, real-time bedside assessment for pediatric respiratory care. Its routine integration requires standardized protocols and age-specific normative data to ensure reliable interpretation and clinical impact.
