Ketamine for Pain, Opioid Use, and Mental Health in Orthopedic Trauma Patients

Participants in this group will receive a single intravenous (IV) dose of ketamine at 0.5 mg/kg, administered within 30 minutes of anesthesia induction during surgical fixation for musculoskeletal trauma. The purpose of the intervention is to evaluate ketamine's effect on postoperative pain, opioid consumption, and psychological recovery, including symptoms of depression and post-traumatic stress disorder (PTSD).

Participants in this group will receive standard general anesthesia during surgical fixation for musculoskeletal trauma. No ketamine will be administered. This group serves as a comparison to evaluate the effects of ketamine on pain, opioid use, and psychological recovery.
