[Role of entropy-based neuromonitoring during cardiac surgery].

The paper deals with a role of spectral entropy-based neuromonitoring at cardiac surgery. Eighty cardiosurgical patients were examined. The depth of entropy-based anesthesia was monitored in all the patients. The patients enrolled into the study were divided into 2 groups. Anesthesia was carried out in the study group (n=40), by taking into account entropic parameters, and in the control group (n=40) on clinical grounds. Information on entropic parameters in this group was accessible only to an investigator and inaccessible to an anesthesiologist who had made anesthesia. The results of the study indicated that entropy-based neuromonitoring permits more controllable and predictable anesthesia to be achieved, makes an individual adjustment of the doses of sedatives easier for each patient, at the induction of anesthesia particularly, enables hypo- and hyperhypnotic episodes to be timely revealed, thus reducing the frequency of hypo- and hyperdynamic reactions by 2.4 times.
