Spontaneous pneumothorax was more frequently seen in patients with COVID-19 compared to patients without COVID-19, and may be associated with worse outcomes than spontaneous pneumothorax alone or COVID-19 without spontaneous pneumothorax.
The incidence and prevalence of a first-ever spontaneous pneumothorax in patients with chronic obstructive pulmonary disease (COPD) and emphysema are increased significantly in men and in Black patients.
Regardless of the type of trauma, type of chest ultrasonography operator, or type of CUS probe used, the overall sensitivity of CUS is superior to supine chest x-ray for diagnosing pneumothorax.
Conservative management with initial observation may be noninferior to immediate interventional management for carefully selected patients with primary spontaneous pneumothorax.
