IBIS Data Library: clinical description of the Finnish database

Improved monitoring of brain function in intensive care and surgery is a pr oject aiming to develop methods of biosignal processing and interpretation, in order to characterise critical events during anaesthesia and cardiac su rgery, effect of anaesthesia regimen, neurophysiological findings of differ ent sedation levels, arousal from post-anaesthesia sedation, post-cardiopul monary bypass brain dysfunction and early brain dysfunction in patients wit h multiple organ failure. A data library was collected in the three partici pating hospitals. This is a description of the data library from the Univer sity Hospital of Kuopio, Finland, which includes data from 40 patients afte r cardiac surgery and from seven patients with multiple organ dysfunction. This project demonstrates that active neuromonitoring can be performed in t he intensive care unit without interference with the normal treatment and c are. The presented database may serve other scientific workers as a referen ce for a typical spectrum of perioperative data with respect to severity of disease, length of cardiopulmonary bypass, postoperative levels of sedatio n and length of hospital stay in cardiac surgery patients, and for types of diseases and outcome in patients with multiple organ dysfunction.
