AbstractMany common elective surgeries are associated with moderate-to-severe postoperative pain. These common surgeries include total knee and total hip arthroplasty, thoracotomy, and multilevel lumbar spine surgery. Unfortunately, many patients requiring these surgeries are already in moderate-to-severe pain, necessitating high doses of oral or transdermal opioids preoperatively. This is an established risk factor for difficult-to-control postoperative pain.(1,2) Opioid-sparing interventions are important elements in these patients to promote convalescence and reduce common opioid side effects such as constipation, confusion, pruritus, nausea, vomiting, and urinary retention. Potential interventions to reduce postoperative pain can include nonsteroidal anti-inflammatory drugs, acetaminophen, gabapentin, and even invasive therapies such as epidural or peripheral nerve blockade. Ketamine is a well-known anesthetic agent that has opioid-sparing analgesic properties, is noninvasive, and in analgesic doses, has few contraindications. This article will review the basic science behind ketamine, some of the evidence supporting its perioperative use, and the logistics of how the Department of Anesthesia at Mayo Clinic in Jacksonville, Florida rolled out a hospital-wide ketamine infusion protocol.
