Fig. 1. Neurologic performance scores on postoperative day (POD) 1 (n = 12), POD 2 (n = 7), POD 3 (n = 7), and POD 7 (n = 3) after deep hypothermic circulatory arrest (DHCA) and for cardiopulmonary bypass (CPB)-only animals (n = 3). Scoring system ranged from 0 to 95, corresponding to no neurologic deficits (normal examination findings) to severe damage (brain death), respectively. Box shows 25–75 interquartile range;bar shows median score. Performance score increased significantly at POD 1 and 2, indicating impaired neurologic function (*P < 0.05).
