目的探讨更换一次性水封瓶时间长短与胸腔感染的临床意义。方法对404例行胸腔闭式引流而且排除胸腔感染者使用随机数字表分为4组，同时对404例患者的胸腔内积液或胸腔引流管前端2厘米进行细菌培养[1]，最后进行统计学分析。结果一次性水封瓶内生理盐水的细菌培养均为阴性，4组水封瓶中胸腔引流液的细菌培养结果阳性共14例，各组比较差异均无显著性(P>0.05)。结论一次性水封瓶的更换时间与胸腔感染无直接关系，水封瓶更换时间与水封瓶内细菌定植无明显相关性，在严格无菌操作下，对于胸腔引流管留置时间较长的患者，一次性水封瓶以每周更换一次较为合适。

Objective To investigate the correlation between the replacing interval of disposable water-seal bottle and thoracic infections. Methods 404 patients with thoracic closed drainage and without thoracic infections at the beginning participated in this study. Patients were randomly divided into 4 groups according to random number table. Bacterial culture was performed for normal saline and drainage fluid in the water-seal bottle as well as the thoracic transudate or effusion in 2 cm length of the drainage tube end. The results were compared statistically. Results Bacterium was not found in normal saline in the disposable water-seal bottle but was found in 14 drainage fluid specimens from 4 groups and totally 8 kinds of bacterium were found. The bacteria were firstly found in Group A when it was the third time to replace the bottle (on the third day). Group C is the last group to be found bacteria when it was the second time to replace the bottle (on the fourteenth day). No significant difference was found among the four groups (P>0. 05). Bacteria were found in 2 of 404 cases with bacterial culture of thoracic transudate or effusion in 2 cm length of the drainage tube end. The bacteria type of one case was the same with the drainage fluid in the disposable water-seal bottle while the other was different. Conclusion The replacing interval of water-seal bottle has no obvious correlation with thoracic infection and bacterium reproduction in the bottle. To replace the water-seal bottle every 7 days is reasonable for those patients requiring longer chest tube placement.
