Detection and follow-up of diaphragmatic dysfunction and lung parenchymal changes by ultrasound in intensive care patients receiving long-term mechanical ventilation
Büşra PEKİNCE, Yeşim Şerife BAYRAKTAR, Jale Bengi ÇELİK

TL;DR
This study uses ultrasound to monitor diaphragm and lung changes in ICU patients on long-term mechanical ventilation, finding no significant diaphragm dysfunction over time but noting improvements in lung ultrasound scores.
Contribution
The study provides empirical evidence on the stability of diaphragm function and lung parenchymal changes during prolonged mechanical ventilation in ICU patients.
Findings
No significant changes in diaphragm thickening fraction, amplitude, or thickness were observed over 10 days of mechanical ventilation.
Lung ultrasound scores significantly decreased from day 1 to day 10, indicating improvement in lung parenchymal conditions.
LUS scores were higher in patients with chest radiography infiltration, showing its utility in assessing lung health.
Abstract
ABSTRACT Detection and follow-up of diaphragmatic dysfunction and lung parenchymal changes by ultrasound in intensive care patients receiving long-term mechanical ventilation Introduction: Previous studies have reported that diaphragm atrophy and dysfunction might occur during mechanical ventilation (MV), but the frequency, effect on mortality, underlying causes and functional outcomes of diaphragm and lung parenchymal changes during routine MV have not yet been fully understood. Materials and Methods: The lung parenchyma and diaphragm of 50 patients were investigated using ultrasound (USG) on day 1, 5, and 10 of MV therapy. Results: Mean age of the patients was 64.90 ± 15.96 years. Mean MV duration was 90.18 ± 21.09 days. Mean thickening fraction (TFdi) on day 1, 5, and 10 was 40.77 ± 15.42, 39.85 ± 16.85, and 43.57 ± 19.10, respectively. Mean diaphragm amplitude on day 1, 5,…
