Abstract
Background: Bedside chest radiography (CXR) is routinely performed on a daily basis to assess lung status for the critically ill patients. However, the technical difficulties during the procedure have led to the incorrect assessment of most common lung pathologies diagnosed in the ICUs, like pneumothorax (PTX), pleural effusion, lung consolidation, and acute interstitial syndrome (AIS). Recently, lung ultrasound (LUS) has become a new reliable, accurate, and attractive tool for diagnosing most of these lung pathologies.
Aim and objectives: The aim of the study is to evaluate the use of bedside chest ultrasound in detecting different respiratory diseases in ICU admitted patients and correlate the obtained results with the final diagnosis at discharge.
Subjects and methods: A cross sectional study was held in Fayoum General Hospital, at the radiology and ICU departments including 35 cases of critically ill, ICU admitted male and female patients with any respiratory symptoms or complications. The duration of the study ranges from 6-12 months.
Results: Regarding Ultrasound findings of the studied patients, in the study in our hands, the most prevalent finding was varied between consolidations with air bronchogram, hypoechoic wedge shaped avascular pleural based lesions and thick septate pleural collection, loculations & echogenic debris. As regard chest X-ray, the most prevalent finding was varied between lobar opacifications with obliterated costophrenic angle by effusion and opacifications & lenticular shaped pleural fluid with its concavity towards the lung. As regard CT findings, the most prevalent finding was varied between defects within pulmonary arteries and thickened pleura & loculated pleural effusion with split pleural sign.
Conclusion: The results and advantages of thoracic US make it a suitable diagnostic modality for evaluating pulmonary and pleural pathologies in the ICU that will have the upper hand over CXR and chest CT in the following decades.
