About
The aim of this study is to evaluate the effect of leg elevation on the prevention of intraoperative hypotension during shoulder surgery in the Beach-chair position. patients undergoing shoulder surgery in the Beach-chair position will be randomly assigned to Group L (with leg elevation) or Group C (no intervention). The primary outcome is the incidence of intraoperative hypotension (mean blood pressure < 60mmHg or systolic blood pressure < 80% of baseline). Secondary outcomes are the incidence of intraoperative cerebral desaturation (cerebral oxygen saturation < 80% of baseline, longer than 30 seconds), total amounts of administered inotropic agents, and systolic blood pressure, heart rate, and cerebral oxygen saturation at various time points.
