The Effect of a Single Hemodialysis Session on Cochlear Function of Patients with End-Stage Renal Disease.

Background/

Objectives

To determine the effect of single-dose hemodialysis treatment on the inner ear in patients with normal hearing functions using the Distortion product otoacoustic emissions (DPOAE) test.

Methods

A total of twenty-four (24) patients with end-stage renal disease were included in the study. For all patients, the DPOAE test was performed immediately before hemodialysis and 3 h after hemodialysis. Both amplitude and signal-to-noise ratio (SNR) values were compared.

Results

Compared to pre-dialysis values, the DPOAE test showed a statistically significant decrease in both amplitude and SNR values at all frequencies (1000, 2000, 4000 and 6000 Hz) in patients' post-dialysis measurements.

Conclusions

A single hemodialysis treatment has been found to have an adverse effect on cochlear function at both low and high frequencies.
