Chart showing the change in intraoperative hemodynamics with the values of circulatory monitors. Compared with pulmonary arterial catheter-based cardiac output (PACO), arterial waveform-based cardiac output (APCO) fluctuated more wildly in a different way from arterial blood pressure (ABP), especially while the right adrenal gland vessels were being resected, though the continuous infusion dose of propofol and remifentanil remained unchanged. (1) 12:35—there was a sudden surge in ABP immediately after the surgeons began operating the right adrenal gland, and a subsequent bolus injection of phentolamine mesylate decreased ABP. (2) 13:00—devascularization of the tumor was completed. (3) 13:08—stroke volume variation (SVV) increased from 10 to 17 after the devascularization. (4) 13:30—a rapid infusion of albumin stabilized circulatory hemodynamics. (5) 13:38—resection of the right adrenal gland tumor was completed
