It places patients at an increased risk of major morbidities and even death. The objective of the study was to investigate the risk predictors of prolonged hypotension in patients undergoing open surgery for PPGLs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The present study adopted a retrospective, single\u2010center design. Patients who underwent open surgery for PPGLs were enrolled from January 1, 2002, to December 31, 2018, at Peking University First Hospital. Perioperative variables were screened from patients\u2019 electronic medical records. Prolonged hypotension was defined as hypotension that required continuous catecholamine support for at least 30\u00a0min to maintain a systolic blood pressure of &gt;\u200990\u00a0mmHg after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 162 patients were included in the study. Fifty\u2010two patients (31.1%) had prolonged hypotension with a median vasopressor support duration of 14 h (IQR\u2009=\u20094\u201330 h).

Patients with prolonged hypotension had a higher incidence of complication, were more frequently admitted to the intensive care unit, underwent mechanical ventilation for a longer duration, and had a
