Abstract: 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.
