Abstract: Objective To investigate the influence factors of temporary catheter obstruction after sealing in the CRRT.Methods A total of 811 patients undergoing the CRRT in ICU of our hospital from July 2015 to March 2016 were included in the study. Retrospective analysis was used to investigate the influence factors of CRRT temporary catheter obstruction.Results A number of 755 out of 811 patients were catheter unobstructed,while 56 cases (6.9%) had catheter obstruction. Single factor analysis showed that 5 factors including APTT,PLT,modes of anticoagulation,diabetes and anticoagulants,had statistically significant (t/χ2=5.133,6.092,53.548,10.646,4.765;P<0.05). Logistic multivariate linear regression analysis showed that PLT,history of diabetes,APTT and modes of anticoagulation were influence factors of catheter obstruction after sealing.Conclusions The main influences factors of the CRRT temporary catheter occlusion after sealing were PLT,diabetes,APTT and modes of anticoagulation. However,further multicenter study with large sample size is necessary.
