Abstract
Abstract
Introduction: The diaphragm is the main muscle that powers breathing. Impaired function of the diaphragm can lead to respiratory complications and often prolongs the duration of mechanical ventilation. Conversely, mechanical ventilation itself may lead to diaphragm atrophy and dysfunction, which are well-recognized features of critically-ill patients, a condition that may contribute to the failure of weaning from mechanical ventilation.
Bedside ultrasonography has been recently proposed as a simple and non-invasive method of quantification of diaphragmatic contractile activity in ICU. Ultrasound can be used to determine diaphragm excursion which may help to identify patients with diaphragm dysfunction. Ultrasound examination can also allow for the direct visualization of the diaphragm thickness in its zone of apposition. Thickening during active breathing has been proposed to reflect the magnitude of diaphragmatic effort, similarly to an ejection fraction of the heart.
Objectives: This work aims to make a systematic review on the role of diaphragm ultrasound in guiding weaning from mechanical ventilation.
Data sources: Medline databases (Pubmed, Medscape, Science Direct, EMF-Potal) and all materials available in the Internet till 2017.
Summary: Ultrasound can be used to assess diaphragmatic function in mechanically ventilated patients which is so important because diaphragm is the main respiratory muscle and prolonged mechanical ventilation may cause diaphragmatic dysfunction.
