Abstract P175: Impact of Serum Hemoglobin Level for Successful Cardiac Resuscitation

Aim: It has been recently recognized that anemia is one of risk factors for major adverse cardiac events among the patients with cardiac diseases. However, it is unknown whether serum hemoglobin level could affect the outcome of cardiac resuscitation. We hypothesize that cardiac resuscitation in patients with anemia is less successful than in those without anemia. Methods: This retrospective observation study was conducted in an academic emergency department (ED) in Tokyo. During the period of 30 months since January 2002, 164 patients with out-of-hospital cardiac arrest were brought to the ED by ambulance. Of those, 139 cardiac arrests were caused by acute illness. Excluding 51 arrests without witness, the remaining 88 patients (67±16 y/o, 66 male) with cardiac arrest including 66 presumed by cardiac etiology were entered into this study. Ventricular fibrillation was observed in 24 patients and asystole was observed in 20 patients as an initial rhythm. Bystander chest compressions were performed in 39 pa...
