Descriptive Information
Brief Title  ICMJE Post-op Ketamine Study
Official Title  ICMJE Evaluation of Post Operative Pain Following Primary Total Knee Arthroplasty (TKA) With Intraoperative Subanesthetic Ketamine Administration and Spinal Anesthesia
Brief Summary The purpose of this study is to establish the effect of sub-anesthetic dosing of ketamine with spinal anesthesia during total knee arthroplasty on post-operative pain and narcotic consumption. We hypothesize that sub-anesthetic ketamine will decrease post-operative pain and narcotic consumption and may secondarily lead to shorter lengths of stay, faster rehabilitation, improved postoperative outcomes and patient satisfaction.
