Effects of enflurane on visual evoked potentials in humans.
Effects of enflurane on visual evoked potentials (VEP) were studied in eight healthy female patients. Control VEP were recorded from the occipital electrode (OZ-CZ), and prominent negative (N70) and positive (P100) peaks were observed following flash light stimulation. After induction of anaesthesia with thiopentone, VEP were recorded at expired concentrations of 1.2, 1.8, 2.4 and 2.7% of enflu...
متن کاملMid-latency auditory evoked potentials during ketamine anaesthesia in humans.
We studied mid-latency auditory evoked potentials (MLAEP) during induction of general anaesthesia with ketamine 2 mg kg-1. MLAEP were recorded before, during and after induction of general anaesthesia on the vertex (positive) and mastoid (negative) positions. Latencies of the peak V, Na, Pa, Nb, P1 and amplitudes Na/Pa, Pa/Nb and Nb/P1 were measured. Fast-Fourier transformation was used to calc...
متن کاملVisual evoked potentials in neurosyphilis.
The visual evoked potential (VEP) to pattern reversal was recorded in 79 patients with neurosyphilis. Sixteen patients (20%) had abnormal VEP latencies with a predominance of pathological VEP values in the group of tabes dorsalis (50%) as compared to general paresis (18%) or meningovascular forms (13%). A comparison of the frequency of abnormal VEPs with that of other ophthalmological tests (vi...
متن کاملVisual evoked potentials in neurobrucellosis.
OBJECTIVE To investigate whether visual evoked potentials (VEPs) are valuable for distinguishing between brucellosis with or without neurological involvement. METHODS A total of 23 patients who were admitted to the Department of Infectious Diseases and Microbiology, and Neurology, Ministry of Health Ankara Education and Research Hospital, Ankara, Turkey between December 2004 and August 2005 w...
متن کاملThe Effect of Oral Verapamil on the Visual Evoked Potentials in Definite Multiple Sclerosis Patients
Introduction: Ionic channel rearrangements through the demyelinated axons or supporting media play significant role in remission of the neurological deficit in MS patients. In this study the effects of Verapamil as a calcium channel blocker on central conduction have been investigated through the evaluation of changes in P100 latency of the visual evoked potential. Method: This randomized doubl...
