It has been proposed that anticoagulant activity during continuous renal replacement therapy with nafamostat mesilate can be monitored by using intra-circuit activated clotting time. However, it is still unclear whether activated clotting time would be useful for this purpose. We conducted a retrospective study and included 76 patients who required continuous renal replacement therapy using nafamostat mesilate. ⋯ In sensitive analysis, the duration on continuous renal replacement therapy without bleeding complications was significantly longer for filters with post-tw ACT<262 than for those with post-tw ACT≥262 (p=0.03). This result suggested that post-filter time-weighted average activated clotting time might be a good predictor of bleeding complications during continuous renal replacement therapy with nafamostat mesilate. Further study is required to refute or confirm our findings.
