How Lidocaine Affects Outcomes In Orthopedic Surgery Patients

This study will evaluate the effect of intraoperative lidocaine infusion on postoperative orientation and concentration in elderly patients having general anesthesia for orthopedic surgeries requiring a minimum 2 days hospitalization. This study will also aim to determine whether intraoperative lidocaine infusion during general anesthesia improves recovery and patient outcome, as well as to determine whether lidocaine infusion decreases postoperative opioid (pain medication) usage.
