The effectiveness of sedation in the ICU is routinely assessed by subjective monitor-ing of the patient’s clinical condition or by using the monitors. The aim of our study was to review the monitoring of sedation using bispectral analysis (BIS) in medical-surgical ICU. A retrospective analysis of patients who were treated in the ICU from 2008 to 2014 was made. The data of 104 pa-tients were analyzed. The average values of age are 54.38 (SD ±18,93; median 58). 39 (37,5%) of the patients died. The patients were referred to the ICU from medical (37), surgical departments (23) and trau-matology (44). The patients were treated in the ICU for 13.84 days (SD ±17.29; me-dian 8). The burst suppression pattern was noticed in 31 (29.8%) patients. Delirium occurred in 3 patients after the separa-tion from the ventilator. In heterogene-ous groups of patients, in which BIS was applied, it is not possible to make certain conclusions. The cost of the method unfor-tunately limits its wider usage. It is neces-sary to wait for the results of future studies which will set clear indications for the use of BIS in certain groups of patients.
