Abstract

Blood purification has been widely performed for critically ill patients, even in cases without renal failure. Effective anticoagulation of the extracorporeal circuit is necessary to prevent circuit clotting. We hypothesized that administration of recombinant human-soluble thrombomodulin (rhsTM) to septic patients undergoing blood purification may prevent circuit clotting, because this agent regulates coagulation. We performed a retrospective, single-center, propensity-matched cohort study in the intensive care unit of Nishichita General Hospital. We included septic patients admitted to the intensive care unit from May 2015 to August 2020 who underwent blood purification. Patients who received rhsTM during intensive care unit admission to the end of the first blood purification (rhsTM group) were matched 1:1 with other patients (control group). The primary outcome was the occurrence of circuit clotting during the first blood purification. A total of 138 patients were included in the study [43 patients (31%) in the rhsTM group and 95 patients (69%) in the control group]. After propensity score matching, 42 pairs of patients were selected, and patients in the rhsTM group had a lower incidence of circuit clotting (21 vs. 55%, P = 0.003). One case of major bleeding occurred in the rhsTM group, but there was no difference in the incidence of major bleeding between groups (2 vs. 0%, P = 1.0). In conclusion, this propensity-matched cohort study indicated that the administration of rhsTM to septic patients undergoing blood purification may prevent extracorporeal circuit clotting.
