Background
Regional Citrate Anticoagulation (RCA) is the preferred CRRT anticoagulation strategy for children in the US. Nafamostat Mesilate (NM), a synthetic serine protease, has been used widely for CRRT anticoagulation (ACG) in Japan and Korea. While NM is considered safe and effective, there is a paucity of evidence in pediatric CRRT. We compare the safety and efficacy of NM to RCA for pediatric CRRT.
Methods
Using one pediatric hospital in Japan and one in the US, medical records of patients (pts) <21 years of age on CRRT between 2016-2019 were reviewed, excluding pts receiving CRRT with ECMO. Pt demographics, CRRT characteristics, and outcomes were compared between RCA and NM groups. Filter life (FL), defined as the number of hours a single CRRT filter was in use, was the primary outcome. Safety is assessed by bleeding complications.
Results
76 pts (248 filters) received RCA and 89 pts (226 filters) received NM. Baseline characteristics are shown Table 1. RCA pts were older and received higher Qb. Median FL (hours) did not differ by ACG type (RCA: 35 [16,67] vs. NM: 38 [22,68]. The lack of difference in FL between groups persisted when controlling for pt age and CRRT Qb.
Conclusion
RCA and NM are safe and appear to be equally effective ACG for children receiving CRRT. A prospective randomized trial is required to validate these findings.
