Visual evoked potential monitoring of optic nerve function during surgery.
A study was made with intra-operative flash--visual evoked potentials (VEP) monitored using a fibre-optic/contact lens photo stimulator in 57 patients undergoing intra-orbital surgical procedures with potential risk to the optic nerve. The VEPs recorded under enflurane and nitrous oxide anaesthesia did not differ significantly in latency or amplitude from the pre-operative recordings. Transient...
متن کاملIntraoperative neurophysiologic monitoring during spinal surgery.
Intraoperative neurophysiologic monitoring (IONM) is a battery of neurophysiologic tests used to assess the functional integrity of the spinal cord, nerve roots, and other peripheral nervous system structures (eg, brachial plexus) during spinal surgery. The underlying principle of IONM is to identify emerging insult to nervous system structures, pathways, and/or related vascular supply and to p...
متن کاملIntraoperative monitoring of flash visual evoked potential under general anesthesia
In neurosurgical procedures that may cause visual impairment in the intraoperative period, the monitoring of flash visual evoked potential (VEP) is clinically used to evaluate visual function. Patients are unconscious during surgery under general anesthesia, making flash VEP monitoring useful as it can objectively evaluate visual function. The flash stimulus input to the retina is transmitted t...
متن کاملIntraoperative Somatosensory and Motor Evoked Potential Recording and Electroencephalographic Monitoring Usefulness During Aneurysm Surgery
In the last 20 years, there have been advances in techniques and instrumentation for intracranial aneurysm exposure and obliteration [94]. However, it seems that 32% of the patients, who underwent surgery, suffer a fatal outcome or some form of sequelae [20]. Primary brain damage due to subarachnoid haemorrhage (SAH) and to a vasospasm, is the major cause of mortality and morbidity; but surgery...
متن کاملMonitoring evoked potentials during spinal surgery in one institution.
PURPOSE To review the experience of one tertiary care institution with somatosensory evoked potential (SSEP) monitoring during spinal surgery in order to assess the ability to monitor and predict neurological outcome effectively. METHODS Records of all patients undergoing spinal surgery during 18 mo were retrospectively reviewed. Information from the patient chart included preoperative neurol...
