Four patients with pheochromocytoma underwent pre-surgical treatment with phenoxybenzamine and volemic expansion. The postural hypotension was evaluated by daily monitoring of the arterial pressure and heart rate in clino orthostatism. The patients underwent surgery and hemodynamic monitoring by Swan-Ganz catheter when postural hypotension was at the lowest level. Hemodynamic data were: elevated cardiac output, normal systemic vascular resistance and filling pressure. These results confirm that the orthostatic hypotension reduction is a valid indication to evaluate the effectiveness of the treatment period with phenoxybenzamine and volemic expansion.
4例嗜铬细胞瘤患者在术前接受了苯苄胺治疗和血容量扩充。通过在临床直立位时每日监测动脉压和心率来评估体位性低血压。当体位性低血压处于最低水平时，患者接受手术，并通过 Swan-Ganz 导管进行血流动力学监测。血流动力学数据显示：心输出量升高，体循环血管阻力和充盈压正常。这些结果证实，体位性低血压的减轻是评估苯苄胺和血容量扩充治疗期有效性的有效指标。
