ABR differences before and after dialysis

The aim of the study was the objective evaluation of the hearing organ in c hildren. Seven children aged 6-17 with end stage renal failure treated by h aemodialysis were examined. Four- to five-hour dialyses were performed 2-3 times a week. Pure-tone audiometry was normal in five children. The reactio ns of brain stem responses (latency and interpeak latency) were analysed be fore and after haemodialyses. We conclude that the ABR differences were con nected with biochemical parameters of uraemia. The present study is a preli minary one and will be continued in the future.
