From: Heparin algorithm for anticoagulation during continuous renal replacement therapy
Algorithm for heparin anticoagulation during continuous renal replacement therapy. Algorithm is based on using 10,000 iu heparin in 40 ml of 0.9% NaCl. APC, activated protein C; APTTr, activated partial thromboplastin time ratio; CRRT, continuous renal replacement therapy; HIT, heparin-induced thrombocytopenia; INR, international normalised ratio; iv, intravenous; post-op, postoperative.
