Reliability of bedside ultrasound of limb and diaphragm muscle thickness in critically ill children.

ABSTRACT:

Introduction

We evaluated the reliability of measuring muscle thickness with ultrasound in limbs and diaphragms of critically ill children and determined the sensitivity of these measures to quantitate muscle atrophy over time.

Methods

An expert and trained novice sonographers prospectively measured limb and diaphragm muscle thickness in 33 critically ill children.

Results

Expert and novice intrarater and interrater reliability were similar. Intraclass correlations (ICC) and coefficients of variation (CoV) were better in limbs (ICC > 0.9; CoV 3.57%-5.40%) than in diaphragm (ICC > 0.8; CoV novice 11.88%, expert, 12.28%). Mean relative difference in all muscles was small (1%-8%). Limits of agreement of the relative difference were smaller in limb (<13%-18%) than in diap
