Abstract: Objective To investigate the complications and the treatments of long-term central venous catheter in maintenance haemodialysis patients. Method To retrospective review 339 cases of long-term central venous catheter indwelled in our hospital,and analyse the complications and management during catheterization and use . Results The success of catheterization is 100%.35 patients dead during follow-up process, non of them is catheter-associated.The catheters’ average retention time of the rest 304 patients is 20.0±15.9 months. The major complications during catheterization:the guide wire can not enter the blood vessels in 2 cases,errhysis in 3 cases,palpitate in 4 cases,subclavian vein injuried 1 case,angle of torsion 1 case.Complications in catheter use process:catheter infection in 11 cases,lack of flow 24 cases,the head tube cracks in 1 case.The total of extubation is 25cases. Conclusion For the persistent hemodialysis patients who were not suitable to establish the arteriovenous fistula, the long-term tunneled central venous catheter could be used as vascular access ideally, except that we should pay attention to preventing and treating the complications.
