Abstract The study was conducted prospectively on 50 consecutive patients with acute respiratory failure, 20 patients were admitted to the Chest Departments at Menoufia University Hospital and 30 patients admitted to Kafr El-sheikh Chest Hospital from the period between January 2019 to January 2020. Thoracic Ultrasonography is a low cost, noninvasive, practical, and rapid method for visualization of different chest pathology. There is a growing body of evidence about the high diagnostic accuracy of thoracic UC in the diagnosis of chest diseases and in guiding related interventions. Thoracic US exhibited high sensitivity and specificity in the previous studies assessed its accuracy in the diagnosis in different chest disorders. Patients were diagnosed ARF and included to the study according to ABG. The diagnosis of these cases was based on clinical features, ABG, Chest xray, CT scan, Lung Ultrasonography. Thoracic US chest examination was done by Philips Affiniti 50G machine using grayscale (B-mode), or time-motion mode (M-mode). The patient was positioned in a semi-recumbent position After application of ultrasound gel the selected probe was positioned on the chest wall perpendicular to the skin with the index marker (dot or grove) always pointing at the patient‟s head. The image marker on the screen corresponded to the index marker on the probe and was positioned to the right of the screen when cardiology convention was used and on the left with radiology convention. Radiology convention was used. Gain and depth were adjusted to obtain clear distinction of shades of grey and to cover the whole lung depth. Anterior and posterior axillary lines divided the chest wall into three fields: Anterior, Lateral and Posterior. The fields were further divided into equal quadrants for a total of six areas on each side. The lung was scanned longitudinally moving cranio-caudally to cover all quadrants. To access the posterior quadrant a lateral rotation of the patient is often necessary. |
