100 Patients ages 40-95 with lumbar stenosis to be decompressed are randomized to undergo the procedure with either general anesthesia or local anesthetic with MAC.~Participants will be randomized to either group 1 General anesthesia or group 2 Local + MAC anesthetic group.~Group 1: General Anesthesia: Medically induced unconsciousness that suppresses reflexes and requires intubation (a tube inserted through the mouth and into the airway) to assist in breathing.~Group 2: Local + MAC: Local anesthetic (lidocaine) injected into the site of the incision/dissection with additional IV medication (Propofol) to achieve a state in which the patient is generally aware, but relaxed
Explore efficacy, complications, and other factors associated with anaesthetic choice- To evaluate the efficacy of local + MAC as an alternative anesthetic to general anesthesia and to analyze patients' outcomes and experiences.
