Official title: Intrathecal Morphine Versus Intrathecal Dexmedetomidine Compared to Placebo for Postoperative Pain Relief After Spine Fixation Surgeries: A Randomized Double-Blinded Study
Run by Tanta University · NCT07777627 · Data updated 2026-11-12
This study tests whether delivering pain medicine into the spinal fluid with morphine or dexmedetomidine can better relieve pain after lumbar spine fixation surgery compared with placebo.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 21–60 scheduled for elective lumbar spine fixation under general anesthesia with ASA I–II.
✕Probably not a fit
Patients who do not respond to intrathecal analgesia or who have exclusions (e.g., hepatic/renal/cardiac disease, coagulation disorders, obesity, pregnancy) may not benefit.

What this trial studies
The trial compares intrathecal morphine and intrathecal dexmedetomidine to placebo in adults undergoing elective lumbar spine fixation. It aims to determine which intrathecal agent provides better postoperative pain relief and how each affects recovery. The design involves three arms and focuses on perioperative safety and analgesic efficacy in a spine surgery population. Perioperative factors such as blood loss and pain intensity are considered, with attention to potential drug-specific side effects.
Why it matters
Potential benefit: If successful, patients may experience better postoperative pain control after spine fixation with a potentially safer or more effective intrathecal option.
How similar studies have gone: Prior work has explored intrathecal analgesics for spine surgery with varying success, but direct head-to-head comparison between morphine and dexmedetomidine against placebo remains limited.
