Clamping of the internal carotid artery (ICA) during carotid endarterectomy (CEA) is a critical step. In our neurosurgical department, CEAs are performed with transcranial Doppler (TCD) and somatosensory evoked potential (SEP) monitoring with a 50% flow velocity/amplitude decrement warning criteria for shunting. The aim of our study was to evaluate our protocol with immediate neurologic deficits after surgery for the primary end point.

Transcranial electrical stimulation (tES) can be used to modulate inhibitory circuits in primary somatosensory cortex, resulting in improved somatosensory function. However, efficacy may depend on the...
Motor learning is associated with plasticity in both motor and somatosensory cortex. It is known from animal studies that tetanic stimulation to each of these areas individually induces long-term pote...
Transcranial motor evoked potential (TcMEP) monitoring may be valuable for predicting postoperative neurological complications with a high sensitivity and specificity, but one of the most frequent pro...
The use of shunt during carotid surgery is controversial. Different experiences are found in literature with Transcranial Doppler (TCD), Electroencephalogram (EEG), Stump Pressure (SP) and Somatosenso...
Studies using time-frequency analysis have reported that somatosensory evoked potentials provide information regarding the location of spinal cord injury. However, a better understanding of the time-f...
Up to 5% of total shoulder arthroplasty patients experience transient or permanent nerve injury during surgery. In this study, we will monitor the nerve transmission of the patients' arm t...
The purpose of this study is to determine if intravenous fosaprepitant can interfere with nervous system monitoring signals in patients having surgery under general anesthesia. This medica...
The relation between burst and suppression periods in transcranial and direct cortical recorded EEG with cortical amplitudes median nerve somatosensory evoked potentials is studied. ...
Transcranial Doppler ultrasound is bedside tool use to assess cerebral blood perfusion in critically ill patients. We sought to conduct a prospective, single centre study aiming to determi...
This study aims to examine whether P30 wave of somatosensory evoked potentials (SEP) is related with outcome after cardiac arrest. The study design is a prospective, multicenter-observatio...
The recorded electrical responses from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported. Often used synonymously to event-related potentials which are associated with higher level cognitive processes.
The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.
The electric response evoked in the CEREBRAL CORTEX by stimulation along AFFERENT PATHWAYS from PERIPHERAL NERVES to CEREBRUM.
Somatosensory evoked potentials generated through the application of HEAT to the SKIN with a LASER. They are often used clinically to assess the function of the central nociceptive system and in diagnosing NOCICEPTIVE PAIN.
A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
