BACKGROUND Spontaneous EEG, mid-latency auditory evoked potentials (AEP) and somatosensory evoked potentials (SSEP) have been used to monitor anaesthesia. This poses the question as to whether or not EEG, AEP and SSEP vary in parallel with varying conditions during surgical anaesthesia. METHODS A total of 81 variables (31 EEG, 22 SSEP, 28 AEP) were simultaneously recorded in 48 surgical patie...

Acute focal ischemia was created in 10 cats by unilateral retro-orbital middle cerebral artery (MCA) occlusion. Regional cerebral blood flow (CBF) was determined utilizing the hydrogen clearance technique from electrode recordings within the gray matter and white matter of the ectosylvian gyrus of both hemispheres. The somatosensory evoked potential (SSEP) was obtained during contralateral medi...

A L T H O U G H anaesthetists routinely use a myriad of monitors to assess the integrity of many organ systems, we do not commonly monitor the nervous system. During many operative procedures nervous tissue is placed at considerable risk of injury yet, for the most part, continues to go unmonitored. One of the most common operative procedures which places nervous tissue at risk is spinal surger...

INTRODUCTION Early prediction of a good outcome in comatose patients after cardiac arrest still remains an unsolved problem. The main aim of the present study was to examine the accuracy of middle-latency SSEP triggered by a painful electrical stimulation on median nerves to predict a favorable outcome. METHODS No- and low-flow times, pupillary reflex, Glasgow motor score and biochemical data...

The afferent input following stroke has an important role in motor relearning. The purpose of this study is to describe the relationship between upper limb clinical motor function and the status of the afferent system among chronic stroke survivors. Twenty-four chronic stroke survivors participated in the study. Clinical motor function of the paretic arm was assessed with the upper extremity po...

OBJECTIVE Somatosensory evoked potential (SSEP) is an electrophysiological test used to evaluate sensory innervations in peripheral and central neuropathies. Pudendal SSEP has been studied in dysfunctions related to the lower urinary tract and pelvic floor. Although some authors have already described technical details pertaining to the method, the standardization and the influence of physiolog...
