Lim EK, et al. - This prospective, open label, cross over study was designed to compare a simple regional citrate anticoagulation (RCA) regime with saline flushes for heparin-free low flux haemodialysis, with a focus on the efficacy as well as safety. Findings corroborated that RCA is superior to saline flushes for circuit patency. Furthermore, researchers considered it a simple and safe protocol, that can be followed for low flux haemodialysis.
