The effectiveness of sedation in the ICU is routinely assessed by subjective monitoring 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 patients 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 traumatology (44). The patients were treated in the ICU for 13.84 days (SD ±17.29; median 8). The burst suppression pattern was noticed in 31 (29.8%) patients. Delirium occurred in 3 patients after the separation from the ventilator. In heterogeneous groups of patients, in which BIS was applied, it is not possible to make certain conclusions. The cost of the method unfortunately limits its wider usage. It is necessary to wait for the results of future studies which will set clear indications for the use of BIS in certain groups of patients.
