Survival rate analysis in elderly patients with long-term catheters hemodialysis / 中华老年医学杂志

ABSTRACT

Objective To investigate the survival rate in elderly patients with long-term catheters hemodialysis.Methods A total of 127 elderly patients receiving maintained hemodialysis were included in this study.Patients were divided into two groups according to catheter locationlong term indwelling internal jugular vein catheter group and long term indwelling vena iliac external catheter group.The baseline anthropometric and laboratory parameters were measured.The catheter dysfunction and catheter related complications were observed.Results The incidence of catheter dysfunction was higher in iliac vein catheter group than in internal jugular vein catheter group (51.5 ％ vs.24.5％,x2 =8.459,P=0.015),and there were no significant differences in the catheter related infection rate and cardiovascular (CVD) event rate between the two groups.Kaplan-Meier survival curves showed that mean survival time was lower in vena iliac external catheter group than in internal jugular vein catheter group (1.9 years vs.2.5 years,x2 =10.847,P=0.001),and still was lower after controlling the catheter dysfunction and cardiovascular events (x2 =9.915,P=0.002;x2=4.368,P =0.037).Multivariate logistic regression analysis showed that levels of hemoglobin,creatinine,systolic blood pressure,parathormone and age were the independent risk factors for mortality in elderly patients with long term catheter hemodialysis.Conclusions There is a high incidence of CVD events in elderly patients with long-term catheter hemodialysis.The incidence of catheter dysfunction is higher and the survival rate is lower in elderly patients with long-term indwelling vena iliac external catheter hemodialysis.
