Comparative Study[A comparative evaluation of "cerebral oximetry" during anesthesia with xenon and other anesthetics].
The oxygen status dynamics during the general anesthesia is one of the most important issues of anesthetic monitoring. The set target was to study the cerebral oximetry (rSO2) in anesthesia with xenon as compared with other anesthetics. A total of 80 patients (class ASA I-II) were examined in the venectomy surgery. ⋯ Xenon and ftorotan were shown to contribute to a higher oxygen status and an increased volume of the cerebral blood circulation. In case of xenon mono-anesthesia, there was a smaller increase in the cerebral blood circulation as compared to N2O + ftoratan anesthesia. Further special investigations are needed to give a final answer to the question on whether it is possible to use xenon in neuroanesthesiology and in intensive care of patients with a neuroresuscitation-type pathology of the brain.

[Correction of arterial hypoxemia during early postoperative period].
The article is dedicated to investigating the reasons of development of hypoxemia during the early postoperative period when the patient is switched to an unassisted air breathing. It was established that hypoxemia develops, after abdominal operations with a multi-component total anesthesia, in 68% of patients, although there is a recovery of adequate ventilation of the lungs, and it is related with an insufficient anesthesia, which results in an increased volume of expiratory closure. Epidural anesthesia prevents an increase in the closure volume and development of hypoxemia.

[Normovolemic hemodilution during surgical revascularization of the myocardium].
The hemodynamic efficiency of hydroxyethyl tarch 130/0.4 "Voluven" (HET) was investigated within a method of acute normovolemic hemodilution in 11 patients with ischemic heart disease (IHD) during the implementation of surgical revascularization of the myocardium under the conditions of extracorporeal artificial blood circulation. It was shown, that in case of invasive monitoring of central hemodynamic and of the oxygen-transport function of the blood circulation system, an exfusion of 13.28 +/- 1.53 ml/kg can be regarded as a permissible blood-saving procedure in IHD patients during revascularization of the myocardium. The application of HET 130/0.4 "Voluven" provides for an adequate correction of shifts in the blood circulation system and in its oxygen function--such shifts occur in implementing the acute normovolemic hemodilution in IHD patients.
