Summary
The purpose of this prospective randomized double-blind study is to determine if the novel
technique of ultrasound guided peri-arterial injection of local anesthetic around the femoral
artery decreases ischemic hypertension associated with prolonged lower extremity tourniquet
time during total ankle arthroplasty (TAA) and foot fusion surgeries. Patients will be
randomized 1:1 to receive either local anesthetic or saline, which will be injected
superomedially to the femoral artery in an attempt to block sympathetic afferents and
decrease tourniquet associated hypertension intraoperatively.
