Nineteen patients was operated on hypotensive anesthesia. Twelve cases was scoliosis, three was spinal cord injury in thoracolumbar region and four was other spinal disease. Age was ranged from eleven to forty (mean twenty five). Hypotension was maintained by use of trimethaphan camphor sulfonate. It poseses sympathetic ganglion blocker. In a retrospective study comparing normotensive and hypotensive anesthesia, the average blood loss was remarkably reduced in Harrington instrumentation and posterior spinal fusion for scoliosis. Ischemia of the surgical wound was achieved by hypotension and operative procedure was easily and strictly performed on posterior spinal surgery. None of complication was noted.
