Neuromonitoring

It is assumed that the early detection of insults to the brain is possible and that potential injury can thus be avoided. Technology for continuous neuromonitoring has gained popularity in situations where clinical detection is limited, such as in the state of unconsciousness found in anaesthesia or intensive care. Although a variety of devices are available for neuromonitoring, there is little objective evidence that their use improves outcome. This article summarizes the basic principles that underpin their use.
