Multicenter Study
Cohort study on the prevalence and risk factors for delayed pulmonary complications in adults following minor blunt thoracic trauma.
The objectives of this study are to determine the prevalence, risk factors, and time to onset of delayed hemothorax and pneumothorax in adults who experienced a minor blunt thoracic trauma. ⋯ The presence of at least one rib fracture between the third and ninth rib on the x-ray of the hemithorax is a significant risk factor for delayed hemothorax and pneumothorax.
