    Abstract
    One of the most fundamental aspects of extracorporeal membrane oxygenation (ECMO) is maintaining proper anticoagulation management in order to prevent hemorrhagic or thrombotic events. Anticoagulation on ECMO is most commonly achieved with the use of unfractionated heparin to maintain a minimum anticoagulation level as monitored by activated clotting time (ACT). Heparin's main effect is exerted by binding to and potentiating antithrombin III. Many factors may contribute to a sub-therapeutic ATIII level that may decrease the effectiveness of heparin. A retrospective record review was performed on all adult ECMO patients at the University of Arizona Medical Center between 2008 and 2011, in order to determine optimal ATIII levels for maintaining proper anticoagulation. In addition, we investigated correlations between ATIII levels and hemorrhagic and/or thrombotic events. Variables measured include, ACTs, heparin dose, ATIII dose, ATIII levels, blood product use, and adverse events. Thirty-five patients received ATIII over the course of the ECMO run. Six patients did not receive ATIII and they were found to have used significantly more blood products than those who did receive ATIII. Also, heparin dose dropped significantly 24h after the first dose of ATIII. There is a significant positive correlation between the amount of ATIII given per day and the amount of packed red blood cells transfused per day. The results suggest an ideal therapeutic range of ATIII dosing, where lack of or too much ATIII administration can lead to excessive bleeding.
