Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 40-95 with lumbar stenosis who are appropriate for general anesthesia.

Probably not a fit

Patients with significant nerve root retraction planned, previous fusion operations, or known hypersensitivity to the anesthetics used may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness and safety of using local anesthesia combined with monitored anesthesia care (MAC) compared to general anesthesia for patients undergoing lumbar decompression surgery due to spinal stenosis. A total of 100 patients aged 40 to 95 will be randomly assigned to receive either general anesthesia or local anesthesia with MAC during their procedure. The study aims to analyze patient outcomes, complications, and overall experiences associated with each anesthetic approach.

Why it matters

Potential benefit: If successful, this study could provide a safer and more comfortable anesthesia option for patients undergoing lumbar decompression surgery.

How similar studies have gone: Other studies have shown promising results with local anesthesia and MAC in similar surgical settings, indicating potential for success in this approach.
