The indication for pleural decompression is not well defined. This research aims to study the overall factors determining pleural decompression. Methods: All blunt chest injury patients were retrospectively reviewed from the institutional trauma registry. Patients who underwent chest or whole‑abdomen CT within 24 h were reviewed by a radiologist to identify initial occult hemothorax defined as a negative chest X‑ray with the presence of hemothorax in the CT. The data included demographic data, mechanism of injury, complications, treatments, and characteristics of the hemothorax from the CT. Results: Six hundred and eighty-six blunt chest injury patients were reviewed over a period of 30 months. Eighty‑one (24.9%) patients had occult hemothorax. The mean time from injury to CT was 5.7 h. Most patients (87.6%) were male. Most patients (70.2%) suffered from traffic collisions and 84.4% had rib fractures. Pleural decompression was performed in 25 patients who had significantly thicker hemothorax (1.1 cm vs. 0.8 cm, P < 0.01), higher rate of occult pneumothorax (88% vs. 53.8%, P < 0.01), and lung contusion (44% vs. 15%, P < 0.05) than those who did not undergo decompression. Multivariable logistic regression showed that a thickness of hemothorax >1.1 cm was associated with increased risk of pleural decompression (odds ratio [OR]: 5.51, 95% confidence interval [CI]: 1.42–21.42) and occult pneumothorax (OR: 6.93, 95% CI: 1.56–30.77). Conclusions: Drainage of occult hemothorax after blunt chest trauma was significantly associated with concomitant occult pneumothorax, lung contusion, and hemothorax thicker than 1.1 cm.
