Conferences and Meetings: Monitoring in Anaesthesia

A seminar on monitoring in anaesthesia was held by the Faculty of Anaesthetists at the Royal College of Surgeons on 27 and 28 February. Introducing the speakers, the chairman, Dr. M. K. SYKES (Royal Postgraduate Medical School, London), said that the purpose of the meeting was to discuss the fundamentals of monitoring-rather than details of new devices-and to define its place in practice. Monitoring equipment could be used both to take continuous measurements, thus replacing the anaesthetist or nurse, and to extend the range of perception-as in determining gas concentrations. Monitoring, however, was not simply a matter of measurement. Its true function was to warn or advise about changes, a task that required comparing both the past and present condition of the patient. This was particularly important in those systems-notably the cardiovascular and respiratory systemswhich had little buffer capacity and whose failure immediately endangered life.
