Pneumatic Leg Compression and Norepinephrine Requirements in Patients Having Non-cardiac Surgery

Patients assigned to the PLC group will receive a pneumatic leg compression sleeve encompassing the calf and thigh, with sleeve size adjusted according to thigh circumference and manufacturer recommendations. The compression pump will be activated before the start of surgery. After surgery, the responsible trial personnel will deactivate the pump and remove the compression sleeves in the PLC group. There will be no standardized anesthesia management protocol; all decisions regarding hemodynamic management will be made at the discretion of the treating anesthesiologist
