Effects of sleep deprivation on anaerobic exercise-induced changes in auditory brainstem evoked potentials

BACKGROUND: The present study was designed to assess how anaerobic exercise affects auditory brainstem response (ABR) parameters, and whether one night of sleep deprivation could alter these possible exercise-induced changes in ABRs. METHODS: Seven healthy, audiologically normal male students (mean age 22.4 +/- 1.0 years) participated in the study. All subjects underwent anaerobic Wingate test for three times: (i) baseline, (ii) following a full-night of habitual sleep and (iii) following one night of sleep deprivation. ABR measurements were performed before and after the second and the third Wingate tests. Oral body temperatures were recorded at the beginning of all ABR measurements. RESULTS: The latencies of wave III and V significantly shortened by anaerobic loading performed in the day after habitual sleep (4.13 +/- 0.10 versus 4.01 +/- 0.17 ms, P<0.02; and 5.84 +/- 0.26 versus 5.65 +/- 0.23 ms, P<0.03, respectively). One night of total sleep deprivation shortened pre-exercise latencies and altered exercise-induced changes in ABRs. CONCLUSION: The findings obtained in the present study show that acute anaerobic exercise is effective on ABR wave latencies independent from body temperature changes, and sleep deprivation has some modulatory effects on exercise-induced changes in ABR.     

脑干听觉诱发电位和体感诱发电位对昏迷患者预后的判断

目的脑干听觉诱发电位(BAEP)和体感诱发电位(SEP)与昏迷患者预后密切相关,探讨BAEP和SEP判断昏迷患者脑功能状态的可行性和准确性。方法采用丹麦Dantec公司生产Neuromatic2000型肌电图诱发电位仪。检查ICU病房中36例昏迷患者的BAEP和SEP。BAEP分析III-V波,SEP分析P15、N20、P25波。检查结果分为正常和异常。预后分为好转和死亡。结果36例患者,BAEP正常12例,异常24例。SEP正常13例,异常23例。好转13例,死亡23例。当SEP异常时,死亡率明显高于SEP正常时。而同时伴有BAEP异常时,死亡率更高。14例患者SEP检查P15、N20、P25波均消失,12例死亡,病死率为86%。5例患者BAEP检查III-V波和SEP检查P15、N20、P25波均消失,全部死亡,病死率为100%。结论BAEP和SEP的正常与否与昏迷患者的预后有密切关系(P=0.011)。SEP异常是判定的主要根据。BAEP和SEP相结合,则可以提高判断的准确性。对昏迷患者进行动态的BAEP和SEP观察可提高判断的准确性。     

Use of brainstem auditory evoked potentials in pediatric brain death

Brainstem auditory evoked potentials (BAEPs) were examined prospectively in ten clinically brain-dead and 13 comatose nonbrain-dead children. All clinically brain-dead children failed to demonstrate brainstem impulse transmission, displaying no waves or only wave I. The comatose, nonbrain-dead children maintained evidence of brainstem electrical activity, manifested by at least two waveforms. This suggests that BAEPs are a useful noninvasive method of supporting the clinical diagnosis of brain death in children.

Automated monitoring of brainstem auditory evoked potentials in the operating room

We monitored brainstem auditory evoked potentials in 112 patients undergoing retromastoid craniectomies for microvascular decompression. To provide information on latency changes as quickly as possible, we implemented a block averaging technique of data acquisition with automatic tracking of wave V latency, which is the most clinically useful information. A change in peak latency probably due to surgical manipulation was observed in 63% of the patients, and the change could be at least partially corrected by modification of surgical technique. Twenty percent ot the 89 patients who underwent preoperative and postoperative audiometric testing showed a postoperative hearing decrement. Some patients had large intraoperative increases in latency without suffering postoperative hearing deficits, and some incurred hearing deficits even though the intraoperative latency increases were relatively small. However, patients whose brainstem auditory evoked potentials were lost during surgery, even temporarily, were likely to have postoperative hearing decrements. Patients who had deficits tended to have slightly greater increases in latency than patients without deficits, but the difference in the mean increases ot the two groups was not statistically significant. Most of the deficits were small, and all resolved over time.
