Participant Flow
All patients included were evaluated by the vascular surgery service and had lower extremity amputation deemed necessary based on ischemic disease, infectious disease, and/or disfiguration. Patients were selected from 2018-2020 at the following sites; Community Regional Medical Center, Clovis Community Medical Center, and Fresno Heart and Surgical Hospital.

Treatment
Patients randomized to the treatment group will receive regional nerve blocks (sciatic and femoral) with bupivacaine at the dose of 1 mg/kg.
Bupivacaine: Patients randomized to the treatment group will receive regional nerve blocks (sciatic and femoral) with bupivacaine at the dose of 1 mg/kg.

Control
Patients randomized to the control group will receive two needle sticks (in the sciatic and femoral distributions) with normal saline to maintain the double-blinded investigation.
