title: What's new in monitoring the coronary surgery patient?
abstract: Monitoring has been extensively reviewed in most textbooks of cardiothoracic surgery and anaesthesia, particularly in the recent textbooks on monitoring edited by Carol L Lake 1 and Casey D Blitt 2 and in the Journal of Clinical Monitoring. Although monitoring properly includes both pre- and postoperative periods, this review will concentrate exclusively on the operative period.  I will also concentrate on new approaches or information which relate to more traditional approaches to monitoring.  The emphasis in this review will not be on what we can monitor, but rather on what we should monitor.  In this regard, I will analyse accuracy and identify sources of error and try to answer the following questions.  Does the device or parameter measure (monitor) what we want to know?  Does it improve patient outcome and safety?  Is it cost-effective? Unfortunately, data are not always available to answer all these questions at present, but hopefully the discussions will make us aware of what we do and do not know, and what we should look for in the near future.
