As with the following case, the intraoperative evoked reponses may be too poor to be reliably monitored. An anesthetic that would increase the amplitude of evoked responses might make the response usable for monitoring. Etomidate may be such an agent. As shown in several studies, etomidate increases the amplitude of cortically derived median nerve SSEPs. We now report a case in which the introduction of etomidate during a narcotic anesthetic improved SSEPs responses from posterior tibial nerve stimulation and allowed the patient's neural function to be monitored when it would otherwise have been considered unreliable.
