40 Hz auditory steady-state response and EEG spectral edge frequency during sufentanil anaesthesia.
PURPOSE The auditory steady-state evoked response (ASSR) is an evoked potential which provides a sensitive measure of the effects of general anaesthetics on the brain. We used pharmacokinetic-pharmacodynamic (PK-PD) modelling to compare the effects of sufentanil on the amplitude of the ASSR with its effect on spectral edge frequency (SEF) of the electroencephalogram. METHODS Nine patients sch...
متن کاملAuditory steady state response in auditory neuropathy.
REVIEW Auditory neuropathy is a disorder characterised by preservation of outer hair cell function, with normal otoacoustic emissions and/or cochlear microphonics, but an absent or distorted auditory brainstem response. PURPOSE This study aimed to objectively assess hearing thresholds in patients with auditory neuropathy, using the auditory steady state response. MATERIALS AND METHODS Thirt...
متن کاملAuditory sensitivity in children using the auditory steady-state response.
OBJECTIVE To determine the effectiveness of auditory steady-state response (ASSR) as a measure of hearing sensitivity in young children suspect for significant hearing loss. DESIGN Within-subject comparisons of click auditory brainstem response (ABR) thresholds and ASSR thresholds. SUBJECTS The study population comprised 42 children suspect for hearing loss and subsequently referred for hea...
متن کامل[Auditory steady-state response in the auditory evaluation: clinical application].
BACKGROUND the auditory steady state response (ASSR) is an electrophysiological procedure that evaluates, at the same time, the hearing thresholds of both ears at various frequencies. This procedure reduces the time of testing and enables the stimulation of levels close to 125dB HL, characterizing residual hearing. AIM to verify the applicability of the ASSR to determine the hearing threshold...
متن کاملAntagonism of sevoflurane anaesthesia by physostigmine: effects on the auditory steady-state response and bispectral index.
BACKGROUND Physostigmine, a centrally acting anticholinesterase, antagonizes the hypnotic effect of propofol, as shown by the return of consciousness (response to commands) or wakefulness (spontaneous eye-opening without response to commands) and by recovery of auditory evoked potentials (40 Hz auditory steady-state response (ASSR)) and the bispectral index (BIS). We measured the effects of phy...
