Abstract

BACKGROUND: Radiologic data remains the gold standard for the diagnosis of pneumothorax (PTX). The use of ultrasonography (US) has recently emerged as the method of choice with physicians who can perform bedside US.

PURPOSE: To compare the diagnostic accuracy of lung US against bedside chest radiography (CR) for the detection of PTX using thoracic computed tomography (CT) as the gold standard.

MATERIALS AND METHODS: We conducted a prospective, single-blind study on 192 critically ill patients; each patient received lung US examination, bedside CR, followed by thoracic CT scan searching for PTX.

RESULTS: Of the studied patients, CT of the chest confirmed the diagnosis of PTX in 36 (18.75%) patients of which 31 were diagnosed by thoracic US while CR detected only 19 cases. Overall lung US showed a considerable higher sensitivity than bedside CR (86.1% vs. 52.7%), lung US also showed higher, negative predictive values, and diagnostic accuracy against CR (96.8% vs. 90.1%), and (95.3% vs. 90.6%), respectively. CR had a slightly higher specificity than lung US (99.4% vs. 97.4%), and higher positive predictive values (95.0% vs. 88.6%).

CONCLUSION: Lung US is an accurate modality more than anteroposterior bedside CR in comparison with CT scanning when evaluating critically ill mechanically ventilated patients, patients underwent thoracocentesis, central venous catheter insertion, or patients with polytrauma.
