Limb Occlusion Pressure Tourniquets to Decrease Pain After Surgery

Currently a standard tourniquet pressure is used for orthopedic surgeries. High tourniquet pressure had been associated with adverse side effects such as ischemia, muscle weakness, and post operative pain. Limb Occlusion Pressure, LOP, is based off the patient's systolic blood pressure plus a safety margin and is typically much lower than standard tourniquet pressure. The aim of this study is to determine if using LOP during orthopedic surgeries decreases post-operative pain and opioid consumption and improves patient's outcomes.
