Abstract:
Objective To investigate the effect of different pipe flush methods on the life of the filter used in CRRT without heparin.Methods 108 patients of CRRT without heparin were randomly divided into observation group (56 cases) and control group (52 cases).The control group used conventional 100 ml 0.9％sodium chloride solution to flush the filter and pipe once for an hour,while the observation group stopped the treatment every 6 hours,first used heparin saline (50 mg/L),second 0.9％ sodium chloride solution to flush,and then continued the treatment.The number of filter and its average service time were compared during the process.Results The number of filter used to treat patients with secondary renal failure,MODS,severe pancreatitis,poisoning,epidemic hemorrhagic fever and cerebrovascular accident complicated by pneumonia in the observation group was respectively 68,26,39,28,21 and 26,all of which were higher than that of the control group (71,35,55,36,24,30,respectively),and the differences were not statistically significant (x2 =28.34,15.61,18.08,19.31,18.50,respectively; P ＜ 0.05 ).The service time of the filter in the observation group was (11.60 ± 1.51 )h,higher than that of the control group which was (9.48 ± 1.29 )h,and the difference was statistically significant ( t =2.79,P ＜ 0.05 ).Conclusions In the CRRT without heparin treatment,the method of intermittent saline with heparin and 0.9％ sodium chloride solution can reduce the clotting of the filter,extend its life and cut patients' treatment cost.
