Abstract: Abstract］ ObjectiveTo explore the effect of continuous negative pressure drainage in the postoperative recovery of tuberculous empyema necessitatis. MethodsSixtyeight patients with tuberculous empyema necessitatis were researched, 34 patients treated by continuous negative pressure drainage were in the observation group,and the other 34 patients treated by passive drainage were in the control group. The amount of postoperation drainage, drainage duration, postoperative visual analogue scale(VAS) score, postoperative hospital stay, lung recruitment, and the rate of poor incision healing were compared between the two groups. ResultsThe drainage duration and the postoperative hospital stay of the observation group was shorter than the control group, the difference was statistically significant(P＜005). The amount of postoperation drainage and the postoperative VAS score of the two groups were not significantly different(P＞0.05). The rate of poor incision healing of the observation group was lower than the control group, the difference was statistically significant(P＜005). ConclusionOn the basis of strict indications, continuous negative pressure drainage showed many positive effects in postoperative recovery of tuberculous empyema necessitates.
