[Implementation of modern principles of blood saving methods at cardiac surgery under extracorporeal circulation].
The introduction of principles of bloodless surgery into different areas of practical medicine is favoured by not only risks from donor blood transfusion, but also by the results of the researches dealing with the body's adaptation to acute anemia, with the determination of its allowable limits, and with much experience with bloodless operations used in Jehovah's Witnesses. The present study was undertaken to make a scientific-and-practical assessment of actual own blood funds and their introduction in order to decrease or refuse to use donor blood at cardiac surgery under extracorporeal circulation (EC). ⋯ The introduction of the above own blood saving methods may decrease the use of donor erythrocytes and freshly frozen plasma by 2.6 and 1.8 times, respectively, may completely refuse transfusing thromboplasma, assure adequate hemostasis, reduce the incidence of adverse reactions associated with donor blood transfusion in cardiac surgical patients. A complex use of the developed saving donor blood methods and pharmaceuticals aimed at improving hemostasis allowed donor blood transfusion to be completely refused in more than 70% of patients at aortocoronary bypass surgery under EC.

[Cerebral oximetry during cardiac surgery under extracorporeal circulation].
The time course of changes in rSO2 were studied in 58 patients during the uncomplicated course of cardiac operations under extracorporeal circulation (EC) and moderate hypothermia. rSO2 was also compared with central hemodynamic parameters, bioelectrical cerebral activity, and hemoglobin oxygen saturation of the bulb of the internal jugular vein (jbSO2). In the pre- and postperfusion period there was a significant correlation of rSO2 and jbSO2 (p = 0.01), yet with a low correlation coefficient (r = 0.348). During EC, no correlation was found between rSO2 and jbSO2 (p = 0.09, r = 0.386). ⋯ In patients from both groups, a reduction in rSO2 occurred at the beginning of EC and at the maximum of cooling. But if in Group 1 patients, the significant reductions in rSO2 at the beginning of EC coincided both with that in mean blood pressure (BPmean), as compared to the baseline values (from 75.55 +/- 10.68 to 66.5 +/- 11.73 mm Hg, p = 0.01), and with the change in the frequency spectrum of EEC (a decrease in the frequency of the right edge, as compared to the baseline values, from 20.77 +/- 1.44 to 19.58 +/- 1.14 Hz, p = 0.01), in Group 2 patients, all significant decreases in rSO2 were accompanied only by a significant reduction in BPmean, but without changes in the frequency spectrum of EEG. It should be noted that over the uncomplicated course of an operation all changes in rSO2 were in the normal range of age-related values.

Clinical Trial Controlled Clinical Trial[Study of analgesic efficacy of propacetamol in the postoperative period using a double blind placebo controlled method].
The efficiency and safety of postoperative use of propacetamol was estimated in 30 patients by means of double blind placebo controlled method. The first group consisted of 15 patients to whom propacetamol was introduced intravenously in single dose of 2 g along with patient controlled anesthesia with promedol. ⋯ So it permits to consider propacetamol as basic non-opioid analgesic. In early postoperative period combination of propacetamol and opioid analgesic (promedol) reduces demands in the latter by 44%.

[Preparations for peripheral and segmental level protection of the patient in the system of general anesthesia and postoperative analgesia].
The traditional general anesthetics and opioid seem to be insufficient for complete protection of the patient from operative trauma in major surgery. The prospective study has been done in 2 groups of patients undergoing abdominal oncological operations with multimodal general anesthesia based on midazolam, propofol, phentanyl and calipsol in microdose in preventive and postoperative analgesia by ketoprofen in the 1st group (35 cases) and the same general anesthesia in combination with prolonged epidural anesthesia with ropivacaine. Both complete anesthesia and postoperative analgesia have been achieved in each group of the patients, but in the 2nd group the doses of generally introduced analgesics with central action--phentanyl and calypsol--were threefold and twofold less, respectively, and restoration of gastric and intestinal peristalsis was more rapid (1.5 day) vs control group (3.5 days). The importance of using all the mentioned components of anesthesia and analgesia before, during and after operation to prevent the defects of antinociceptive protection and subsequent development of postoperative pain syndrome has been pointed out.

[Use of analgesics with peripheral action in the system of complex protection of the patient from operative trauma].
Obtained for many years experience of perioperative using of analgesics with peripheral effect is summarized. The special scientific analysis was carried out in 274 patients who got different analgesics with peripheral action (aspisol, baralgin, ketoprofen, ketorolak, contrikal) at different stages of preoperative period in combination with opioid. The control group included 30 patients who got monoanalgesia by promedol after abdominal operations. ⋯ After severe traumatic abdominal or thoracal operations non-steroid anti-inflammatory drugs are used in combination with other potent analgesic with peripheral action--cortical and opioid buprenofine in minimal dose of 0.35 mg/day with good analgesic effect. To prevent the central sensitization during general anesthesia ketamine in microdose 0.5-1.0 mg/kg*hour is always used. The conclusion is made on the important role of multimodal preventive and continuous perioperative antinociceptive protection.
