Diaphragmatic Shortening Fraction and Pulmonary Ultrasound Combined Analysis for Extubation Success Prediction in Critical Care Patients
In Brief
An observational study evaluating Thoracic ultrasound for Airway Extubation. Completed, enrolled 82 participants across 1 site.
Detailed Summary
The primary objective is to assess whether the fraction of diaphragmatic shortening in combination with the presence / absence of alveolar-interstitial syndrome evaluated through chest ultrasound may predict successful extubation in adult patients hospitalized in the intensive care unit.
Study Details
Timeline
Interventions
The ultrasound will be performed using the ultrasound system GE Logiq XP equipped with a linear probe of 10 MHz. The diaphragm is visualized as two parallel echogenic lines at the eighth intercostal space in the mid-axillary line. The images will be captured during the inspiratory and expiratory tidal volume to and during maximum inspiration and expiration. Each image will be frozen in B mode and the diaphragm thickness will be measured from the center line pleural half the peritoneal line. The fraction of diaphragmatic thickening it is calculated by the formula: diaphragmatic thickness at the end of inspiration - thickness to diaphragmatic at the end of exhalation / diaphragmatic thickness at the end of exhalation x 100. The number of areas with lines B also will be measured.
