This study is looking at different types of anesthesia for people having surgery for lumbar spinal stenosis (a narrowing of the spinal canal in the lower back). Researchers want to see if using a local anesthetic (Lidocaine) combined with a relaxing medication (Propofol) is as effective and safe as general anesthesia (being completely asleep). You could be eligible if you are between 40 and 95 years old and need surgery for lumbar stenosis in 1 to 3 segments of your spine. The study will measure changes in your disability (using the Oswestry Disability Index score) and your pain levels for up to two years after surgery to see how well each anesthesia method works. The current recruitment status is unclear, but the study plans to enroll 100 participants.

Study design

This is an interventional study where 100 participants aged 40-95 will be randomly assigned to receive either general anesthesia or local anesthesia with Propofol for their lumbar decompression surgery.
