Abstract

It is essential during extracorporeal membrane oxygenation (ECMO) to extend the activated clotting time (ACT) using anticoagulants to prevent blood clot formation. Traditionally, heparin has been used as an anticoagulant during ECMO. Hemorrhaging due to systemic heparinization is considered a major complication of ECMO. A 48-year-old man was admitted due to cardiogenic shock with acute myocardial infarction. ECMO was instituted because of recurrent ventricular tachycardia and refractory shock. We used nafamostat mesilate (Futhan) as an anticoagulant to reduce hemorrhagic complications. The total bypass time was 153 h. The average dose of nafamostat mesilate was $2.64{\pm}1.11$ mg/kg/h; the average ACT was $128.68{\pm}21.24$ seconds. Only a few units were transfused, and there was no oxygenator failure or hemorrhagic complications. Thus, nafamostat mesilate may reduce the need for transfusions and hemorrhagic complications during ECMO.

체외막산소화장치를 사용하는 경우 항응고제의 사용은 필수적이며, 그 동안 헤파린이 널리 사용되어 왔다. 하지만 헤파린은 출혈 위험성을 증가시키며, 이로 인해 중대한 합병증이 발생할 수 있다. 이 증례에서 저자들은 심인성 쇼크를 동반한 급성 심근경색증 환자에서 체외막산소화장치의 항응고제로 nafamostate mesilate를 사용하였다. 항응고제로 nafamostat mesilate만 사용한 기간에는 nafamostat mesilate를 평균 $2.64{\pm}1.11$ mg/kg/hr의 속도로 투여하여 ACT를 평균 $128.68{\pm}21.25$초로 유지하였고, 헤파린을 함께 사용한 기간에는 nafamostat mesilate를 $1.17{\pm}0.34$ mg/kg/hr, 헤파린을 $3.83{\pm}1.0$ Unit/kg/hr 의 속도로 투여하여 ACT는 평균 $140.2{\pm}14.47$초로 유지하였다. 기존의 헤파린을 항응고제로 사용한 환자들과 비교하였을 때, 사용된 oxygenator 갯수와 수혈량이 모두 적었다. 저자들은 체외막산소화장치의 항응고제로 nafamostate mesilate를 사용하여 출혈에 의한 합병증이나 oxygenator의 교환없이 성공적으로 치료된 예를 경험하여 이를 보고한다.
