Study of Alpha-blockers Alone During Preoperative Preparation in Patients With Pheochromocytoma

Clinical Study of Abandonment of Intravenous Volume Expansion After Preoperative Use of α-blockers in Patients With Adrenal Pheochromocytoma

Study of the relationship between hemodynamic stability and preoperative intravenous rehydration in patients with pheochromocytoma

All patients were subclassified into either the hemodynamic stability group (HS group) or the hemodynamic instability group (HU group) according to whether intraoperative hemodynamic instability occurred. Differences in data between the two groups were examined, and the risk factors for intraoperative hemodynamic instability were analyzed using logistic regression.
