Summary
Patients meeting enrollment criteria will be randomized 1:1 to either the dobutamine or the control group. In the dobutamine group, 3\~6μg/kg/min dobutamine will be injected intravenously after anesthesia induction until hemostasis is completed. To ensure preload, transesophageal echocardiography (TEE) will be used to monitor left ventricular end-diastolic volume (LVEDV) and stroke volume (SV). In the control group, 3mL/h normal saline will be injected intravenously after anesthesia induction until hemostasis is completed, and the liquid will be restricted according to the currently commonly used principle of low central venous pressure(LCVP), nitroglycerin can be used if necessary.
