[Significance of brainstem auditory evoked potential determination in chronic renal failure and maintenance hemodialysis patients].

Brainstem auditory evoked potentials (BAEP) were measured in 20 chronic renal failure patients and 8 maintenance hemodialysis patients. The BAEP in chronic renal failure patients was showed that wave I, III, V peak latencies (PL) and I-III, I-V interpeak latencies (IPL) were markedly increased. The significant reductions, although not to normal, of wave III, IV PL and I-III, I-V IPL were recorded in postdialysis (average 4.2 months) compared with that in predialysis. A correlation analysis revealed no consistent relationships between plasma proteins, hemoglobin, urea, creatinine serum electrolytes and BAEP PL or IPL. The authors realize that BAEP could be used as a subjective index in deciding the inner ear and nervous system damage in chronic renal failure, and it also provided an electrophysiologic evidence for the relationship of Kidney and ear in traditional Chinese medicine.
