Transcranial Doppler Monitoring

  • E. B. Ringelstein

Abstract

The monitoring concept in neurology, neurosurgery and vascular surgery refers to the continuous or intermittent evaluation of nervous and/or circulatory functions in order to detect otherwise obscure alterations of the patient’s condition. The underlying idea is that monitoring delivers immediate information about potential hazards or the effectiveness of interventions and thus may lead to rapid modifications of therapy. Monitoring of representative parameters is of particular interest if the desired information cannot be acquired with more common methods, for instance, by clinical examination of the patient. This is why monitoring techniques are predominantly applied in non-cooperative or comatose patients. This is particularly the case in the operating room, during intensive care and neuroradiological or surgical interventions, where immediate information about the induced changes in the patient’s state is lacking (Hacke 1985, Ringelstein et al. 1985 b, Ringelstein et al. 1986).
