THE USE OF NEW LUNG ULTRASOUND SCORE AS A PREDICTOR OF WEANING OUTCOME IN MECHANICALLY VENTILATED PATIENTS

Abstract

Mechanical ventilation (MV) is the most common therapeutic modality used for critically ill patients. MV is a critical intervention to sustain life in acute or emergent settings. This procedure involves applying positive pressure breaths and relies on the airway system's compliance and resistance.To maximize the benefits of the ventilator and minimize the risk of complications in critically ill patients, it is important to avoid both premature extubation and unnecessary prolongation of MV.Using ultrasound can help to predict the weaning and extubation outcome as it is easy to use, non invasive, available and repeatable at the bedsideDiaphragm ultrasound is used to assess and measure diaphragm excursion and diaphragm thickening fraction Lung ultrasound is used to measure modified lung ultrasound score (0-24) it is better than classical LUS score (0-36) as it is easier and decreases the movement of critically ill patients at beds.AIM OF THE WORK:The aim of our work was to evaluate and assess the value of lung and diaphragm ultrasound to predict weaning and extubation outcome, using diaphragm thickening fraction (DTF), diaphragm excursion (DE), modified lung ultrasound score (mLUS score) and rapid shallow breathing index (RSBI).
