Human auditory brain stem response during induced hyperthermia.
A continuous monitoring of auditory brain stem response (ABR) and esophageal (Tes) and rectal temperatures (Tre) were recorded in male undergraduate subjects to investigate a relationship between the interpeak latencies (IPLs) and core temperature. The average change of Tes (36.8-39.5 degrees C) was achieved by immersing the subjects in a temperature-controlled water bath (30-42 degrees C). The IPLs became shorter with the rise in body temperature and were correlated with both Tes and Tre. The average slopes for IPL(I-III) and IPL(I-V) were significantly higher than those for IPL(III-V). The present study of humans indicated that changes of IPL(I-III) and IPL(I-V) were 0.11 and 0.16 ms, respectively, per 1 degree C change in core temperature during induced hyperthermia.
