IBIS data library: clinical description of the Finnish database. Improved Monitoring for Brain Dysfunction during...

Improved monitoring of brain function in intensive care and surgery is a project aiming to develop methods of biosignal processing and interpretation, in order to characterise critical events during anaesthesia and cardiac surgery, effect of anaesthesia regimen, neurophysiological findings of different sedation levels, arousal from post-anaesthesia sedation, post-cardiopulmonary bypass brain dysfunction and early brain dysfunction in patients with multiple organ failure. A data library was collected in the three participating hospitals. This is a description of the data library from the University Hospital of Kuopio, Finland, which includes data from 40 patients after cardiac surgery and from seven patients with multiple organ dysfunction. This project demonstrates that active neuromonitoring can be performed in the intensive care unit without interference with the normal treatment and care. The presented database may serve other scientific workers as a reference for a typical spectrum of perioperative data with respect to severity of disease, length of cardiopulmonary bypass, postoperative levels of sedation and length of hospital stay in cardiac surgery patients, and for types of diseases and outcome in patients with multiple organ dysfunction.
