Abstract

Somatosensory evoked potential (SSEP) monitoring has been used to minimize neurologic morbidity during spine surgery. SSEP monitoring may be affected by technical factor including operation, physiological factor associated with patient and anesthetics used to induce and maintain general anesthesia. Several clinical studies have shown that inhaled anesthetics more decrease the amplitude of SSEP than a narcotic based general anesthesia. We have experienced 15 patients who received spine surgery under balanced anesthesia with propofol, remifentanil and 50% N2O, which is supposed to be another useful anesthesia technique for spine surgery under SSEP monitoring.

Key Words: propofol, remifentanil, somatosensory evoked potentials
