The value of bedside ultrasound is increasingly being recognised in the ICU, to assist in diagnosis and allow therapeutic interventions to be performed effectively and safely. This study examines the role of ultrasound in the diagnosis of radio-occult pneumothorax in the ICU.
Prospective study of 70 proven consecutive pneumothoraces in 64 ICU patients (60 proven on chest X-ray and the remainder only on CT scan)
Control group consisted of 238 lungs in 119 consecutive ICU patients (absence of pneumothorax proven by CT scan). In 17 of these patients pneumothorax was suspected
Ultrasound examination of all patients to identify the relationship between the presence/absence of 'lung sliding', 'comet-tail artifacts', and 'lung point', and pneumothorax (for description of these terms please see original article)
In the study group of 66 analyzable pneumothoraces, 'lung sliding' and 'comet-tail artifacts' were absent. 'Lung point' was present in 44 of the pneumothoraces. However, in the control group of 233 analyzable lungs however, 'lung point' was absent, whereas 'lung sliding' was present in 182 and 'comet-tail' artifacts was present in 146. The 'lung point' had a sensitivity of 66% and a specificity of 100% for the diagnosis of pneumothorax.
