Resumen
Evoked potentials (EPs) occur in the peripheral and the central nervous system. The low amplitude signals are extracted from noise by averaging multiple time epochs time-locked to a sensory stimulus. The mechanisms of generation, the techniques for stimulation and recording are established. Clinical applications provide robust information to various questions. The importance of EPs is to measure precisely the conduction times within the stimulated sensory system. Visual evoked potentials to a pattern reversal checker board stimulus are commonly used to evaluate the optic nerve. Auditory evoked potentials following ‘click’ stimuli delivered by a headset are most often used to test the auditory nerve and for prognostication in comatose patients. Somatosensory evoked potentials to electrical stimulation of distal nerves evaluate the peripheral nerve and the lemniscal system, and have various indications from demyelinating diseases to the monitoring of operations and prognosis of comatose patients.

Resumen
Transcranial electrical stimulation is a well-recognized method for corticospinal tract (CT) activation. This article explains the use of TES during surgery and highlights the physiology of the motor-evoked potentials (MEPs). It describes the techniques and methods for brain stimulation and recording of responses. There are two factors that determine the depth of the current penetrating the brain, they are: choice of electrode montage for stimulation over the scalp and the intensity of stimulation. D-wave collision technique is a newly developed technique that allows mapping intraoperatively and finding the anatomical position of the CT within the surgically exposed spinal cord. Different mechanisms may be involved in the pathophysiology of postoperative paresis in brain and spinal cord surgeries so that different MEP monitoring criteria can be used to avoid irreversible damage and accurately predict the prognosis.

Resumen
This chapter describes how the activity of neurons produces electrical potentials that can be recorded at the levels of single cells, small groups of neurons, and larger neuronal networks. It outlines how the movement of ions across neuronal membranes produces action potentials and synaptic potentials. It considers how the spatial arrangement of specific ion channels on the neuronal surface can produce potentials that can be recorded from the extracellular space. Finally, it outlines how the layered cellular structure of the neocortex can result in summation of signals from many neurons to be large enough to record through the scalp as evoked potentials or the electroencephalogram.

Resumen
Intraoperative monitoring and testing is conducted to improve neurological outcomes from surgery that incurs risk of neurological injury. Many techniques are familiar from the outpatient neurodiagnostic laboratory, and can be applied with minor modifications to the operating room setting. Other techniques are specific to the operating room. Transcranial electrical motor evoked potentials cannot be applied to awake patients, but are commonly used under general anaesthesia. Monitoring teams understand the tactics for obtaining quality recordings and calling alarms when potentials change past preset limits. Surgeons and anaesthesiologists have a variety of tactics for responding to adverse neurodiagnostic changes beginning with easy actions. In experienced hands, intraoperative neurophysiological monitoring substantially reduces post-operative deficits. For example, in spinal cord monitoring the risk of paraplegia and paraparesis is reduced by 60%. Monitoring is carried out by a technologist in the operating room under the supervision of an experienced neurophysiologist. In straightforward cases, the neurophysiologist may remotely monitor from outside the operating room.

Resumen
This chapter describes the many methods that can be used to investigate neurological disorders. The application and suitability for specific disorder types are outlined, as are contraindications for use. Methods of imaging the central nervous system include computed tomography (CT) imaging, several magnetic resonance (MR) scanning methods, Single photon emission computed tomography (SPECT) and Positron Emission Tomography (PET). Invasive (angiography) and non-invasive methods of imaging the cerebral circulation are also outlined.The standard method of recording electrical activity of the brain is the electroencephalogram (EEG), which is heavily used in epilepsy to investigate regions of epileptogenesis.Other investigations described include evoked potentials, nerve conduction and electromyography studies, the examination of cerebrospinal fluid and the diagnostic use of neurological autoantibodies. Finally, neurogenetics, neuropsychological assessment and the assessment of treatments by randomized trials are discussed.

Resumen
In patients with cervical myelopathy, the spinal cord is already compromised to a point at which there is little reserve for surgical maneuvers and the slightest adverse action can result in dramatic consequences. Awake fiberoptic intubation and neurological assessment before induction of anesthesia could be the safest way to avoid waking up the patient before proceeding with surgery in the case of absent motor evoke potentials (MEPs) in spite of increasing the stimulating voltage together with increasing the rate of stimulating pulses. Hypotension is an additional factor, which may lead to irreversible neurologic deficit in a partially compressed but functionally intact spinal cord. Intraoperative neurophysiologic monitoring for cervical myelopathy should include somatosensory evoked potentials, transcranial electric MEPs, and electromyography to provide complementary information and monitor different spinal cord tracts and individual nerve roots.

Resumen
Chapter 25 introduced some basic generic principles applicable to many measurement and monitoring techniques. Chapter 43 introduces those principles not covered in Chapter 25 and discusses in detail the clinical applications and limitations of the many monitoring techniques available to the modern clinical anaesthetist. It starts with non-invasive blood pressure measurement, including clinical and automated techniques. This is followed by techniques of direct blood pressure measurement, noting that transducers and calibration have been discussed in Chapter 25. This is followed by electrocardiography. There then follows a section on the different methods of measuring cardiac output, including the pulmonary artery catheter, the application of ultrasound in echocardiography, pulse contour analysis (LiDCO™ and PiCCO™), and transthoracic electrical impedance. Pulse oximetry is then discussed in some detail. Depth of anaesthesia monitoring is then described, starting with the electroencephalogram and its application in BIS™ monitors, the use of evoked potentials, and entropy. There then follow sections on gas pressure measurement in cylinders and in breathing systems, followed by gas volume and flow measurement, including the rotameter, spirometry, and the pneumotachograph, and the measurement of lung dead space and functional residual capacity using body plethysmography and dilution techniques. The final section is on respiratory gas analysis, starting with light refractometry as the standard against which other techniques are compared, infrared spectroscopy, mass spectrometry, and Raman spectroscopy (the principles of these techniques having been introduced in Chapter 25), piezoelectric and paramagnetic analysers, polarography and fuel cells, and blood gas analysis.

Resumen
Our understanding of arrhythmias following resuscitated cardiac arrest has evolved over the past two decades to entail complex pathophysiological processes including, in part, ischaemia and ischaemia-reperfusion injury. Electrical instability after the return of spontaneous circulation (ROSC) is common, ranging from atrial fibrillation to recurrent ventricular tachycardia and fibrillation. Electrical instability following out-of-hospital cardiac arrest is most commonly due to myocardial ischaemia and post-arrest myocardial dysfunction. However, electrolyte disturbances, elevated catecholamine levels, the frequent use of vasopressors and inotropes, and underlying structural heart disease or channelopathies also contribute in the acute setting. Limited data exists that specifically address the management of arrhythmias in the immediate post-arrest period. In addition to treating any potential reversible cause, the management in the haemodynamically-stable patient includes beta-blockers, class I (lignocaine and procainamide) and III anti-arrhythmic agents (amiodarone). Defibrillation is often needed for recurrent ventricular arrhythmias.

Resumen
This article gives information on the clinical application of motor-evoked potential (MEP). Transcranial stimulation of the cerebral cortex to elicit MEPs is a noninvasive method for assessing the integrity of the central motor pathway function. Transcranial magnetic stimulation (TMS) is used in diagnosing and monitoring neurological disorders. This article highlights the neurophysiological differences between TMS and transcranial electric stimulation. All the different MEP parameters that can be measured by TMS, the latency of the MEP is generally regarded as the most reliable and useful. TMS studies have been described in many neurological disorders. The sensitivity of TMS in detecting subclinical upper motor neuron lesion varies in different disorders, depending on number of muscles and different parameters used. This article talks about the application of MEP in pathophysiology, multiple sclerosis, motor neuron diseases, meyloptahy, cerebral infarction, movement disorders, epilepsy, Lumbar spinal stenosis and radiculopathies, peripheral nerve disorders etc.
