以往自发性气胸常需手术置入较硬的胸腔导管作闭式引流 ,由于管径较粗 ,组织相容性差 ,并发症多 ,常导致病人的不适。导管过细 ,如中心静脉导管 ,由于引流量不足且管腔容易堵塞 ,往往收不到治疗效果。为此 ,我们选择管径适中的一次性吸痰管作为胸导管作闭式引流治疗自发性气胸 In the past spontaneous pneumothorax often require surgical placement of harder thoracic catheters for closed drainage, due to coarser diameter, poor tissue compatibility, complications, often lead to patient discomfort. Catheter too thin, such as the central venous catheter, due to inadequate drainage and lumen easy to plug, often do not receive treatment. To this end, we choose a moderate diameter disposable suction tube as a thoracic duct for the treatment of closed drainage of spontaneous pneumothorax
