目的：观察深静脉导管治疗自发性气胸的疗效。方法：深静脉导管组：从穿刺点将深静脉导管置入胸腔作闭式引流。套管针组：在穿刺点行皮肤切开,逐层分离组织,以套管针置入硅胶管行胸腔闭式引流。比较两组的疗效。结果：深静脉导管组与套管针组在平均肺复张时间、复张率及并发症的出现等三项指标上无明显统计学差异(P＞0.05),另发现深静脉导管插管胸腔闭式引流术还具有一些优点。结论：深静脉导管插管胸腔闭式引流术是一种简单、安全、实用、有效的治疗方式。
Objective: To observe the curative effect of deep vein catheter in the treatment of spontaneous pneumothorax. Methods: Deep vein catheterization group: deep venous catheters were inserted into the thoracic cavity for closed drainage from the puncture point. The trocar group: the skin at the puncture point incision, layer by layer separation of tissue to the trocar silicone tube into the chest closed drainage. Compare the curative effect of two groups. Results: There was no significant difference between the deep venous catheter group and the trocar group in the mean time of reexpansion, the recovery rate and the occurrence of complications (P> 0.05), and the deep venous catheterization was also found in the thoracic cavity Closed drainage also has some advantages. Conclusion: Deep venous catheterization of thoracic closed drainage is a simple, safe, practical and effective treatment.
