[Information method of EEG analysis in anesthesiology]. / Informatsionnyi metod analiza EEG v anesteziologii.

An information concept of nociceptive impulses is proposed. The device for quantitative analysis of information coming to CNS has been constructed and approved. It is demonstrated that monitoring of informative loading of EEG may be used for evaluation of anesthesia adequacy. Level of this index from 40 to 50% corresponds to effective protection.

[Target control infusion of propofol: is this method really preferable?]. / Infuziia propofola po tselevoi kontsentratsii: est' li u metoda real'nye preimushchestva?

In order to elucidate the advantages of target control infusion (TCI) over common manually controlled infusion, we evaluated the results of 54 anesthesias carried out at department of roentgeno-endovascular surgery. All 54 patients received intravenous controlled sedation with propofol. The rate of arrest of sedation signs after the end of infusion, hemodynamics during anesthesia, comfort for the patient, and convenience for the anesthesiologist were evaluated. As regards intravenous controlled sedation, we observed no obvious advantages of the TCI method for the patient over common manually controlled infusion. Performed by a skilled anesthesiologist, both methods ensure sufficient comfort for the patient, stable hemodynamics, and easy regulation of the depth of sedation. However, TCI is more convenient for physician, and this is the reason why many specialists prefer it.
