Comparison of pre-filter and post-filter ionised calcium monitoring in continuous veno-venous hemodiafiltration (CVVHD-F) with citrate anti-coagulation.
BackgroundIt is widespread practice during citrate anticoagulated renal replacement therapy to monitor circuit ionised calcium (iCa2+) to evaluate the effectiveness of anticoagulation.Whether the optimal site to sample the blood path is before or after the haemofilter is a common question.MethodsUsing a prospectively collected observational dataset
