The patients were randomly divided into two groups. Tube thoracostomy was embedded for all patients. The first group was treated with tetracycline 2 g, 5 mL of lidocaine 2%, and 50 mL of normal saline injected through an embedded thoracostomy tube. The second group was performed with the same procedure without tetracycline injection.
