Fig. 3. MN-SSEP latencies of cortical N20 and cervical N13 at arterial normotension in relation to esophageal temperature. Central conduction time (CCT), i.e. , the difference between N13 and N20, is also presented. Means ± SDs from 11 patients undergoing resection of intraocular melanoma during hypothermia of approximately 32°C.
