The IBIS project: data collection in London

The primary aim of the Improved Monitoring for Brain Dysfunction during Int ensive Care and Surgery (IBIS) project was to create a unique and comprehen sively annotated data library (DL) of multiple physiological, including neu rophysiological, signals. Data collection was undertaken in Kuopio, Finland and London, UK, and comparable protocols were used at all the sites. In Lo ndon, 43 patients were recruited at the Royal Brompton Hospital, followed b y nine at St. Bartholomew's Hospital, all of whom underwent cardiac or comb ined cardiac and carotid artery surgery. Thirty-seven patients underwent a single operation, while 15 underwent two procedures. The protocols and equi pment used, problems specific to the electrically hostile environment and p reliminary results are described, including those of clinical interest. The DL is being used for the development of clinically applicable neurophysiol ogical monitoring tools. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
