Abstract:
Objective By researching the auditory brainstem response(ABR) latency and interpeak latency intervals before and after continuous positive airway pressure through the nares(nCPAP), the experiment explored the pathophysiological and anatomical basis of electric physiological change in patients with obstructive sleep apnea/hypopnea syndrome(OSAHS).Methods The ABR of 45 OSAHS patients(90 ears) and control group(32 ears)was examined,the sleep of patients with OSAHS was monitored by polysomnography(PSG).The results of ABR before and after nCPAP were compared.Results 1.The latency of wave III? V and interpeak latency intervals of I-III,III-V,I-V of patients were longer than that of the control group.2.After nCPAP,wave III and interpeak latency intervals of I-III,III-V changed obviously.Conclusion 1.The OSAHS patients' auditory brainstem structure is impaired,which has relationship with high carbonic acid and low oxygen saturation. 2.Except wave III,produced by upper nucleus olivaris that is near the breathing center,effect of nCPAP on ABR of patients with OSAHS is not obvious.
