Fig. 2. Neurologic performance score on postoperative days 1 and 2 after cardiopulmonary bypass and deep hypothermic circulatory arrest in the desflurane and fentanyl groups. A neurologic performance score of 0 (best) represents no deficits (normal examination findings), and a score of 95 (worst) represents severe deficits (brain death). Horizontal bars represent medians; n = 10 per group.
