摘要
目的探讨血液透析中心静脉带涤纶套留置导管生存率及影响因素。方法随访观察利用中心静脉带涤纶套留置导管在本院行血液透析的43例患者90天,记录置管时患者年龄、性别、原发病、血压、血红蛋白、红细胞压积、血小板、凝血酶原时间、活性部分凝血活酶时间、纤维蛋白原、白蛋白、总胆固醇、低密度脂蛋白和甘油三酯;记录血液透析超滤率、留置颈内静脉临时导管时间和中心静脉带涤纶套留置导管生存时间。用Kaplan-Meier生存分析计算导管生存率;Cox风险回归分析导管存活的影响因素。结果导管90天的生存率及通畅率均为67.4%,但导管60天的生存率为88.2%,通畅率却为82.9%。颈内静脉临时导管留置时间、透析超滤率和Hct水平与导管生存时间呈显著独立负相关(均P<0.05)。结论颈内静脉临时导管留置时间、透析超滤率和Hct水平是中心静脉带涤纶套留置导管存活的重要影响因素。
Objective To investigate the survival rate and related factors of indwelling Dacron cuffed catheter in central vein for hemodialysis.Methods 43 patients with indwelling Dacron cuffed catheter in central vein for hemodialysis had been observed for 90 days.Their ages,gender,protopathy,blood pressure,hemoglobin,hematocrit,platelet,prothrombin time,activated partial thromboplastin time,fibrinogen,albumin,total cholesterol,low density lipoprotein,triglyceride were collected.Ultrafiltration rate,maintenance time of temporary catheter in internal jugular vein and survival time of cuffed catheter were recorded.Survival rate of cuffed catheter was calculated by Kaplan-Meier method,and the related factors of cuffed catheter survival was analysed by Cox regression.Results Both survival rate and petency rate of cuffed catheter were 67.4% in 90 days.However,survival rate was 88.2% while petency rate was 82.9% in 60 days.Ultrafiltration rate,main tenance time of temporary catheter in internal jugular vein and hematocrit level were independent negative correlated with survival time of cuffed catheter respectively.Conclusions Ultrafiltration rate,maintenance time of temporary catheter in in ternal jugular vein and hematocrit are critical influential factors associated with Dacron cuffed catheter survival.
