Under General Anesthesia Arginine Vasopressin Prevents Hypotension but Impairs Cerebral Oxygenation During Arthroscopic Shoulder Surgery in the Beach Chair Position

Abstract

A prophylactic bolus administration of AVP prevents hypotension associated with BCP in patients undergoing shoulder surgery under general anesthesia. However, it was associated with regional cerebral but not jugular venous oxygen desaturation on upright positioning.
