The perioperative experiences of 15 children and adolescents who underwent a total of 18 surgical procedures for resection of a pheochromocytoma were analyzed to determine clinical or hemodynamic events associated with intraoperative or postoperative complications. Of the pre- and intraoperative factors assessed, only preoperative resolution of symptoms and normalization of blood pressure were predictive of uncomplicated outcome. No intraoperative factors were statistically associated with outcome, but the four patients with complicated outcomes had had aggressively administered intraoperative fluids. Noninvasive measures of cardiac function did not help predict outcome; however, echocardiography results were available only for six patients. Two of the patients with complicated outcomes had cardiac dysfunction, suggesting undiagnosed catecholamine-induced cardiomyopathy in the other two with complicated outcomes. Intraoperative fluids should be given based on intraoperative blood pressures, the presence or absence of prior adrenergic blockade, and assessment of preoperative myocardial function. If preoperative myocardial dysfunction is revealed, intraoperative measurement of right atrial and pulmonary capillary wedge pressures may be indicated.
