Objective To evaluate the safety and efficacy of local sodium citrate anticoagulation for routine hemodialysis in high-risk patients with hemorrhage.Methods A total of 150 patients who were admitted to West China Hospital from October 2018 to March 2019 for routine hemodialysis treatment with high-risk bleeding were selected as study objects. The patients were divided into without heparin anticoagulation group (group A) and with 4% sodium citrate anticoagulation group (group B) by random number table method, with 75 cases in each group. Biochemical indicators, serum calcium ion concentration, local anticoagulation safety index of citrate and dialysis adequacy index, blood coagulation in dialyzer and tube during dialysis wre observed in the two groups.Results The coagulation events in group B were significantly lower than those in group A (Z=–4.889, P<0.001), and the urea clearance index in group B was higher than that in group A [(1.26±0.12) vs. (0.73±0.13) L/(min·1.73 m2); t=22.418, P<0.05]. There was a significant difference in the changes of urea nitrogen [(3.53±1.05) vs.(3.12±1.11) mmol/L; t=2.323, P=0.021] 24 hours after dialysis; other indicators showed no statistically significant difference (P>0.05). After the filter, serum calcium ion concentrations in group B at different time points were lower than those in group A [2 hours: (0.52±0.07) vs. (0.64±0.08) mmol/L; 4 hours: (0.56±0.09) vs.(0.63±0.09) mmol/L; t=5.198, 0.525, P<0.001], and the coagulation time was higher in group B than that in group A [2 hours: (172.56±14.78) vs. (151.45±19.81) s; 4 hours: (168.45±16.48) vs. (152.88±16.54) s; t=7.396, 5.775, P<0.001]. None of the patients had dialysis-related adverse events.Conclusion Four percent sodium citrate is effective and safe in anticoagulation therapy for hemodialysis patients, and it can reduce the risk of coagulation in dialyzer and ensure the adequacy of maintenance hemodialysis.
