[Pharmacological and mechanical support of the myocardium in perioperative period in cardio-surgical patients with chronic heart failure].

The article deals with a retrospective study devoted to the combined methods of myocardial support in cardiosurgical patients with chronic heart failure (III-IY FC according to NYHA) and low myocardial reserves capacity (LVEF 28.3 +/- 9.4%).

Hemispheric differences in the mesostriatal dopaminergic system.

The mesostriatal dopaminergic system, which comprises the mesolimbic and the nigrostriatal pathways, plays a major role in neural processing underlying motor and limbic functions. Multiple reports suggest that these processes are influenced by hemispheric differences in striatal dopamine (DA) levels, DA turnover and its receptor activity. Here, we review studies which measured the concentration of DA and its metabolites to examine the relationship between DA imbalance and animal behavior under different conditions.

[Preventive intraaortic balloon counterpulsation during surgical myocardial revascularization].

Fifty patients with low myocardial functional reserves (left ventricular ejection fraction less than 40%, disseminated cardiosclerosis, multiple affection of coronary arteries, NYHA class III-IV) after coronary artery bypass surgery (CABS) were examined. All the patients were divided into 2 groups. Preventive intraaortic balloon counterpulsation (IABC) was used in 24 patients (group 1).

[Effects of free oxygen radicals on impaired lung oxygenating function at aortocoronary bypass surgery].

Fifty five patients with coronary heart disease were examined. Of them 10 patients underwent multiple aortocoronary bypass surgery using intrathoracic or radial arteries under natural circulation, 45 had the same surgery under extracorporeal circulation (ECC). In the patients operated on without ECC, increases in active oxygen forms were rather moderate and practically always occurred with enhancement of antioxidative protective enzymes, the oxygen balance of arterial blood was in the normal range during and after surgery.

[Methods of the use of ketorolac tromethamine in patients during the early postoperative period].

Analgesia with nonsteroid antiinflammatory drugs (NSAID) becomes a pressing problem today. One such drug is ketorolak tromethamine (KT), characterized by expressed analgesic activity comparable with that of opioid analgesics morphine or promedol. Our purpose was to assess KT efficacy in analgesia performed by different methods, including analgesia controlled by the patient (ACP) after surgery.
