ObjectiveTo compare dialysis catheter function and complications according to catheter site in patients undergoing hemopurification.MethodsLiteratures were searched from PubMed, Medline, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Data, and VIP Database according to the inclusion and exclusion criteria. Publication years of these literatures ranged from April 1998 to April 2018. Meta-analysis was performed with RevMan 5.3 software. The odds ratio (OR) and 95% confidence intervals (CI) were calculated for uncontinuous outcomes, and the weighted mean difference (WMD) and 95%CI were calculated for continuous outcomes. The incidence of catheter related infection, other complications and patients outcome were compared between different sites for dialysis vascular access.ResultsA total of 9 articles were included, including 2 randomized controlled trials and 7 observational clinical studies, and 5 220 adult patients undergoing renal replacement therapy. Meta-analysis showed that there was no significant difference in incidences of catheter colonization or catheter-related bloodstream infection, as well as arterial puncture, local thrombosis, catheter dysfunction and spontaneous catheter withdrawal, between femoral and non-femoral (jugular or subclavian) catheterization (P≥0.05). Whereas the incidence of bleeding and local hematoma was lower in femoral catheterization [OR=0.44, 95%CI (0.23, 0.82), P=0.009], and the duration of catheters was shorter in femoral catheterization [WMD=–1.40 d, 95%CI (–2.17, –0.62) d, P=0.000 4]. The blood flow rate, filters clotting incidence and patients intensive case unit mortality were similar in different catheterization.ConclusionsIn patients undergoing renal replacement therapy, the bleeding and local hematoma incidence is lower in femoral catheterization but the duration of catheters is shorter. Nevertheless the patients have similar clinical outcome. This result may provide reference for clinical decision-making.
