Clinicians will carry out randomized treatments in coordination with research staff. The treatments will be: 1) Ephedrine treatment to maintain intraoperative MAP ≥60 mmHg, delayed resumption of chronic antihypertensive medications as monitoring with 5 min. Blood pressure management. The staff anesthesiologist will administer an ephedrine sulfate injection. An initial dose of 5 to 10 mg given as an intravenous bolus is advised for the treatment of clinically significant hypotension during anesthesia to provide an increase in blood pressure in case of MAP< 60 mmHg. However, the dose of each will be titrated as necessary to reach the target mean arterial pressures.
