The purpose of this study is to investigate whether perioperative hemodynamics and postoperative outcomes are related to the duration of DOX administration.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>In total, 132 patients managed preoperatively with single \u03b1-receptor blocker DOX were enrolled. All patients underwent adrenalectomy for pheochromocytoma in the Department of Urology, Peking University First Hospital, between January 2001 and July 2019. Patients were divided into three groups based on the duration of preoperative administration of DOX: group A (\u226414\u00a0days), group B (15\u201330\u00a0days), and group C (&gt;30\u00a0days). Patient and tumor characteristics, intraoperative hemodynamics, and postoperative outcomes were recorded and compared.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>These patients included 57 men and 75 women, with an average age of 48\u00a0years. Clinical characteristics, preoperative hemodynamics, medicine management and surgical approaches were comparable between the three groups. Among the three groups, we found that group C (&gt;30\u00a0days) had the lowest intraoperative minimum heart rate [group A vs. group B vs. group C\u2009=\u200960 (52\u201367) vs. 59 (50\u201361) vs. 51.5 (50\u201358.75), <jats:italic>p<\/jats:italic>\u2009=\u20090.024] and highest risk of postoperative hypotension requiring vasopressor support [group A vs. group B vs. group C\u2009=\u200914 (20.3%) vs. 12 (27.9%) vs. 10 (50.0%), <jats:italic>p<\/jats:italic>\u2009=\u20090.032].<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusion<\/jats:title>\n<jats:p>The current study indicated that preoperative management of pheochromocytoma with single \u03b1-receptor blocker DOX for more than 30\u00a0days after final dose adjustment might lead to intraoperative bradycardia and more postoperative hypotension requiring vasopressor support.
