Hejazi MS, et al. - Among children with severe or profound bilateral sensorineural hearing loss undergoing cochlear implant surgery, researchers compared the impacts of the intravenous anesthesia (propofol and remifentanil) and inhalation anesthesia (sevoflurane) techniques on neuroauditory threshold and stapedial reflex threshold responses of patients. They noted that stapedial reflex may be suppressed or even fully eliminated by using inhalation anesthetics and hence, the use of inhalation anesthetics for achieving controlled hypotension during the cochlear implant surgery should be avoided. A slight impact of remifentanil and propofol infusion on hearing thresholds was evident, and is recommended for determining hearing thresholds during cochlear implant surgeries.
