Abstract

In a randomized study, sequential anticoagulation for hemodialysis (citrate for the first 3.5 h, switching to 30-min anticoagulation-free hemodialysis) was compared to standard citrate anticoagulation. Fifty-two hemodialysis procedures were randomized either to sequential (n = 27) or standard citrate group (n = 25). The antithrombotic effect in the circuit was visually assessed after hemodialysis using a score from 1 (total clotting) to 5 (no clotting). The antithrombotic score for sequential versus standard group was as follows: dialyzer, 4.0 +/- 1.1 versus 4.8 +/- 0.4 (P < 0.01); arterial bubble trap, 4.0 +/- 1.2 versus 4.7 +/- 0.6 (P = 0.013); venous bubble trap, 4.0 +/- 1.3 versus 4.8 +/- 0.6 (P < 0.01). Serum citrate levels during sequential versus standard citrate anticoagulation (micromol/L) were as follows: at the beginning, 143 +/- 65 versus 148 +/- 77 (not significant [NS]); after 2 h, 317 +/- 157 versus 354 +/- 111 (NS); at the end, 125 +/- 81 versus 405 +/- 133 (P < 0.01). Sequential anticoagulation reduces the final serum citrate concentration to predialysis level. It can be a good anticoagulation strategy for patients in whom the reduction of citrate load is desired.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
