Intraoperative monitoring of brain-stem auditory evoked potentials

Journal of Neurosurgery, 1982
✓ Brain-stem auditory evoked potentials (BAEP) were monitored during 54 neurosurgical operations in the cerebellopontine angle. The BAEP were irreversibly obliterated in five patients who required deliberate section of the auditory nerve. Technical difficulties interfered with monitoring in three cases, and three patients had deafness and absent BAEP ...

Brain-stem auditory evoked potentials and brain death

Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1991
BAEP records were obtained from 30 brain-dead patients. Three BAEP patterns were observed: (1) no identifiable waves (73.34%), (2) an isolated bilateral wave I (16.66%), and (3) an isolated unilateral wave I (10%). When wave I was present, it was always significantly delayed.

Electrically Evoked Brain Stem Auditory Potentials

Annals of Otology, Rhinology & Laryngology, 1987
University of Melbourne cochlear prostheses were driven to deliver pulse stimuli at a repetition rate of 10 Hz. Brain stem auditory evoked potentials were recorded in the customary way. The magnitude of the presumed wave V was plotted against stimulus amplitude. Also, 10-Hz square waves of current were injected through a promontory needle into totally

Auditory Brain-Stem Evoked Potentials in Bell's Palsy

Archives of Otolaryngology - Head and Neck Surgery, 1984
In an attempt to assess objectively the integrity of the auditory pathways in patients suffering from Bell's palsy, an audiometric evaluation was performed and auditory brain-stem evoked potentials (ABEP) were obtained from 24 patients within the first week from the onset of facial weakness.

Bessel filtering of brain stem auditory evoked potentials

Electroencephalography and Clinical Neurophysiology, 1981
It has been shown previously that conventional high-pass filtering of the brain stem auditory evoked potential (BAEP) results in significant wave form distortion. This distortion can be drastically reduced by using digital filters with zero-phase properties, but this approach requires the use of a digital computer. The Bessel filter is an approximation

Fentanyl Anesthesia and Human Brain-stem Auditory Evoked Potentials

Anesthesiology, 1984
The effect of incremental doses of fentanyl on brain-stem auditory evoked potentials (BAEPs) was studied in 10 patients scheduled for elective surgery. Seven sets of BAEPs were recorded in each patient starting the day before surgery, after premedication and after 10 micrograms/kg increments of fentanyl up to 50 micrograms/kg.

Brain stem auditory evoked potentials in posterior circulation surgery

Neurosurgery, 1983
Abstract The objectives of this study were to evaluate the use of brain stem auditory evoked potentials (BAEPs) in 10 adult patients with vascular disorders of the posterior circulation that were treated surgically and to compare the BAEPs with the neurological findings. The vascular lesions included basilar artery stenosis in 3 patients.

Brain stem auditory evoked potentials (BAEP) monitoring in brain death

Neurosurgical Review, 1989
In our intensive care unit, brain stem auditory evoked potentials (BAEP) are measured continuously in comatose patients. For this study we examined 15 patients who fulfilled the criteria of brain death (2). Loss of BAEP in these patients inevitably means loss of brain stem function and consecutive death.

Localizing brain stem lesions with brain stem auditory evoked potentials

Acta Neurologica Scandinavica, 2009
Based on a survey of brain stem auditory evoked potentials (BAEPs) in animals and humans with localized brain stem lesions compared to the recognizability of BAEP components in normal materials, it was concluded that BAEP examination might localize lesions to a high or low level and diffusely within the brain stem.
