[Activation of the blood kallikrein-kinin system in disseminated intravascular coagulation in rats. The significance of the pulmonary component and an attempt at correction with aspirin].

It has been shown that the development in animals of disseminated intravascular coagulation (DIC) caused by long-term intravenous infusion of thrombin was accompanied by appreciable activation of the kallikrein-kinin system, being characteristic of acute pathological processes. In the initial stages of the process development, prekallikrein and kallikrein inhibitor were observed to be secreted from the lungs to arterial blood. Further development of DIC led to the depletion of the reserves of the kinin system. Pretreatment with a single low dose of acetylsalicylic acid considerably reduced the total animals' lethality and postponed blood kinin system activation determined by the development of DIC.

[Indicators of lipid metabolism in patients in critical condition].

Plasma lipid metabolism was studied in critical patients with severe combined injuries. Decrease in cholesterol concentration and increase in triglyceride concentrations were more pronounced in patients with lethal outcomes. The authors conclude that plasma cholesterol and triglyceride concentrations can be used as prognostic signs in patients with severe combined injuries.

[Comparative evaluation of methods of analgesia after operations on the stomach].

A general somatic syndromal approach to evaluation of clinical status by SAPS II and APACH II scores was used in 41 patients operated on for gastric cancer. Epidural analgesia in these patients promoted rapid regression of the severity of condition, did not require high opioid doses, had a positive effect on the peristaltic activity of the intestine, and accelerated treatment in intensive care wards.

[Acute hemorrhage. View on the problem].

Acute hemorrhage is a main cause of reduction of blood oxygen capacity. The main aim of correction of sequels of acute hemorrhage is to maintain effective gas exchange by restoring central circulation and microcirculation, the rate of diuresis, by normalizing water-salt exchange, to eliminate anemia, hypoproteinemia, and acute blood coagulability disorders. The values of oxygen budget with calculated oxygen delivery and consumption and those of hemoglobin and hematocrit which are of great value only after recovery of circulating blood volume are considered to be major indications for hemotransfusion. A relationship is established between the extraction and uptake of oxygen and its delivery. The concept of the critical level of oxygen delivery is considered, ways of correcting oxygen indebtedness are presented. Alternatives to the use of hemotransfusions by employing the solutions of modified hemoglobulin and perfluorocarbon-containing emulsions are under consideration. A possible algorithm of aid rendering in acute hemorrhage is given.

[Assessment of unbalance in water compartments of patients with gestosis].

The water-sector misbalance was studied in 53 puerperants. The method of bio-impedance spectrometry was made use of to determine the total body water, extra-cellular- cellular- and interstitial water as well as the circulating blood volume. The levels of extra-cellular and interstitial water were found to be reliably higher in patients with moderate gestosis on day 1 after delivery versus healthy subjects. Stable trends towards normalizing the volumes of extra-cellular and interstitial water were registered by day 5. As for patients with sever gestosis, a reliably increasing total body water as well as extra-cellular and interstitial water persisted in them by day 5 after delivery versus the controls.

[Dynamics of prekallikrein and kallikrein inhibitors in development of acute pulmonary lesion (experimental study)].

The reaction of the kallikrein-kinin blood system was studied in an experimental acute pulmonary lesion caused by a prolonged intravenous infusion of thrombin solution. It was established that the progressing of the acute pulmonary lesion brings about an increasing activation of the kallikrein-kinin blood system with a limited check by the lungs. It is displayed by lower levels of prekallikrein and its inhibitors observed first in the venous and later in the arterial blood. Bradykinin was shown to exhaust and impair the metabolic pulmonary activity. The conclusion is that the indices of the kallikrein-kinin blood system reflect the integrity of the pulmonary metabolic activity and can be biochemical markers of an acute pulmonary lesion.

[Choice of the parameters of artificial ventilation in patients with acute respiratory distress syndrome].

The paper presents the results of use of two modes of controlled artificial ventilation (ALV) in adult patients with acute respiratory distress syndrome of various genesis: 1) ALV with its controlled volume, the descending pattern of inspiratory flow, the limitation of respiratory volume in the airways (RV, 6-8 ml/kg; Ptr.peak < 30 cm H2O), 2) ALV with its controlled volume, the orthogonal pattern of inspiratory flow (RV, 12-15 ml/kg, Ptr.peak > 35 cm H2O). It also shows the advantages and disadvantages of these respiratory procedures in this group of patients.
