Brainstem auditory evoked responses in chronic renal failure and the effect of hemodialysis.
Brainstem auditory evoked responses (BAER) were recorded in patients with chronic renal failure before commencement of chronic dialysis treatment, and in patients with end-stage renal failure on chronic hemodialysis for several years. Both groups of patients had delayed latencies of the third and fifth waves. The patients on hemodialysis revealed delayed latency of interpeak I-V as well. There was no correlation between wave latency, serum urea, creatinine, PTH or duration of chronic hemodialysis treatment. A hemodialysis session led to a slight shortening of the third wave. This study suggests that neural conduction along the brainstem in patients with chronic renal failure is delayed even before hemodialysis is started. Although 1 dialysis session may have some beneficial effect, long-term hemodialysis treatment does not seem to shorten the delay in neural conduction observed in patients with chronic renal failure.
