目的:探讨中心静脉双腔导管血栓形成治疗的有效办法.方法:45例肾功能衰竭留置中心静脉双腔导管的患者,经确定采用中心静脉导管栓塞后,先用尿激酶10万U+生理盐水10 ml配成浓度为1万U/ml尿激酶溶液,予以1 ml注射器于血栓形成侧导管内缓慢注射尿激酶溶液1.0 ml,10 min后再注射尿激酶溶液0.3～0.5 ml,再过10 min注射尿激酶溶液0.3～0.5 ml,保留10 min 后用10 ml注射器抽吸导管,导管通畅即接生理盐水点滴数分钟,若血透导管不通可重复上述步骤.结果:45例采用此法治疗的患者中,43例导管再通,2例因导管栓塞时间大于3 d,溶栓治疗失败,改其他部位重新置管.结论:早期应用此法溶栓治疗导管再通率高,减少患者再次置管的痛苦及经济负担.%Objective: To investigate the effective method of the double-lumen central venous catheter thrombosis. Methods: 45 cases of renal fai1ure, indwelling central venous double-lumen catheter in patients with central venous catheter thrombosis was established, the first with Urokinase 100 000 U+saline 10 ml dubbed concentration 10 000 U/ml Urokinase solution to 1 ml syringe in thrombosis slow side of intraductal injection of Urokinase solution 1.0 ml, 10 min after the injection of Urokinase solution of 0.3～0.5 ml, another 10 min injection of Urokinase solution 0.3～0.5 ml after 10 min with 10 ml syringe to retain suction catheter, immediately following saline drip a few minutes, if the dialysis catheter barrier can repeat these steps. Results: 45 cases of patients treated with this method in 43 cases of ductal patency, catheter embolization in 2 cases because of time greater than 3 days, thrombolytic treatment failure, changed other parts of the re-tube. Conclusion: The early treatment of catheter method has been applied thrombolytic recanlization rate and reduce the suffering of patients with re-catheterization and economic burden.
