Correlation of Measuring Diaphragm Capacity Using Ultrasonography on the Success of Ventilator Removal in ICU-Acquired Weakness (ICU-AW) Patients at RSUD Dr. Soetomo Surabaya

Abstract

Introduction: Generalized muscle weakness that occurs in intensive care unit-acquired weakness (ICU-AW) patients and in the diaphragm muscles leads to increased duration of mechanical ventilation, length of stay, and mortality. The diagnostic modality of changes in diaphragmatic capacity measured using diaphragmatic ultrasound accompanied by motor examination using Medical Research Council (MRC) scoring is effective as an early diagnosis of ICU-AW and diaphragmatic dysfunction. The need for comprehensive healthcare is made part of the universal healthcare package. Objectives: The purpose of this research is to analyze diaphragm capacity in the form of diaphragmatic thickness and excursion using diaphragm ultrasound on the success of getting off the ventilator for ICU-AW patients. Methods: 23 ICU-AW patients underwent diaphragm ultrasound examination during the Spontaneous breathing trial/T-piece process. The correlation between diaphragmatic thickness and excursion scores on success in getting off the ventilator was analyzed statistically. Results: There is a significant difference between the results of diaphragmatic excursion (p=0.001) and thickness (p=0.006) with the success rate of getting off the ventilator. Conclusions: Patients who experience diaphragm muscle dysfunction or weakness have an increased risk of failure to get off the ventilator. The potential benefits of measuring diaphragm capacity using ultrasonography can be considered as a diagnostic tool or early diagnostic in ICU-AW patients need to be explored in further studies with control indicators and larger sample sizes.
