Abstract: ［Abstract］  Objective〖HTSS〗〓To investigate the effect and value of application of continuous irrigation of lesions in the surgery of spinal tuberculosis combined with paraspinal abscess.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The clinical data of 97 patients with spinal tuberculosis complicated with paraspinal abscess were selected, all patients were routinely treated with antituberculosis drugs for 2 to 4 weeks before the operations of debridement and bone grafting with internal fixation. Ninetyseven patients were randomly divided into two groups, 51 cases in the continuous irrigating group and 46 cases in the conventional drainage group. The washing time of the continuous irrigating group was 7-21 days, average（16.0±4.8）  days. Fortysix cases in the conventional drainage group were given routine drainage for 2-10 days, average（7.0±2.3） days. The drainage tube were removed when the drainage fluid<50 mL/24 h. The incision healed, local effusion, early body temperature change and bone fusion of the two groups of patients were observed.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓From day 1 to day 7 after operation, the body temperature of the continuous irrigating group decreased, while the conventional drainage group fluctuated up and down. the body temperature of the continuous irrigating group was lower than the other group. The body temperatures at different points between two groups were statistically significant（P＜005）. The difference of interaction of groups and time points were no statistically significant（P＞005）. In both groups, the erythrocyte sedimentation 21 days after operation were significantly decreased  compared with preoperation, but there were on statistically significant difference（P＞005）. The postoperative effusion rate between two groups were statistically significant（P＜005）.  The incidence of sinus and the rate of secondary surgery were no statistically significant（P＞005）. Two groups of patients achieved bony fusion 1 year after surgery.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓For the patients with spinal tuberculosis, continuous irrigation after the surgery of debridement and internal fixation can significantly reduce the postoperative effusion, empyema and the incidence of early unhealed lesions, reduce the postoperative fever incidence significantly, which is one of the effective methods of treating spinal tuberculosis.
