Awakening test in scoliosis surgery using different anesthetic techniques

ABSTRACT

The intraoperative awakening test is used to detect potential damage to the spinal cord during correction of scoliosis surgery. The awakening test was compared by two anesthetic techniques with controlled hypotensive anesthesia. In group 1, halothane was used as the inhalational anesthetic; while in group 2, propofol infusion was used as the main anesthetic. Each group consisted of 12 patients. It was found that time to open the eyes and move limbs to command during the awakening test was 18.2 minutes in halothane group and 12 minutes in propofol group. There were neither violent movements, nor anxiety reactions during the test
