Brief Summary
Use of neuraxial agents in anesthesia for cardiac surgery is expanding. We have used combined general-spinal anesthesia for cardiac surgery for 12 years. We hypothesized that compared to general anesthesia, the combined techniques would provide comparable intraoperative hemodynamics and improved postoperative analgesia. This study subjected these techniques to a double-blind randomized trial.
