Testing the Feasibility of Using Ropivacaine in Spinal Anesthesia for Patients With Lower Back Surgery

Ropivacaine | Anesthesia, Spinal | Bupivacaine | Neurosurgery

The goal of this pilot clinical trial is to test the feasibility of conducting a randomized controlled trial that will examine the use of ropivacaine in the spinal anesthesia for patients undergoing elective 1- or 2-level lower spine surgery. This study aims to:

* Determine the rates of eligibility, recruitment, consent, and attrition
* Determine the acceptability among patients, surgeons, anesthesiologists, and nurses of doing spine surgery under spinal anesthesia
* Gather preliminary data on outcomes relevant to a future dose-finding study

Participants will be randomized to one of three treatment groups:

* General anesthesia with endotracheal tube
* Spinal anesthesia with bupivacaine
* Spinal anesthesia with ropivacaine
