[OBSTRUCTION OF THE OUTFLOW TRACT OF THE LEFT VENTRICLE DURING CARDIAC SURGERY].

Obstruction of the outflow tract of the left ventricle is well understood as a complication of hypertrophic cardiomyopathy. But other clinical situations are not described in Russian. The aim of this work was the description of the clinical, echocardiographic criteria and pathogenetically substantiated therapy dynamic subaortic obstruction in operations with extracorporeal circulation. Routine echocardiographic monitoring allowed to register obstruction of the outflow tract of the left ventricle in 10 patients during heart surgery (7 men, 3 women) aged 71 ± 16 years, when dealing with extracorporeal circulation (66 ± 22 min): 2 cases--correction of defects of the heart valves, 7--coronary artery bypass grafting. Early diagnosis of this complication in 8 cases, provided a rational choice of effective treatment strategy providing for the rejection of cardiotonics, the appointment of a beta-blocker, infusion therapy maintaining a relative of hypertension. Two patients died, despite the measures taken. Thus, obstruction of the outflow tract of the left ventricle is a rare but dangerous complication of cardiac surgery. Its timely diagnosis is possible using intraoperative echocar- diography.

[The use of lysosomotropic preparations in treating severe experimental chemical eye burns]. / Primenenie lizosomotropnykh preparatov v lechenii tiazhelykh khimicheskikh ozhogov v éksperimente.

The action of membranotropic preparations--mildronat and phosphaden on the course of a severe burn process of the cornea with changes in lysosomal membranes revealed in pathogenesis has been studied in 80 rabbits. As a marking lysosomal enzyme, acid phosphatase was used. Besides this, peculiarities of the clinical course of the burn process have been studied, when treated by common methods and in a complex with the mentioned preparations. The results of the study have shown expressed stabilizing action of the preparations on lysosomal membranes of the cornea in early terms of the treatment, correlative relationship between results of biochemical investigations and clinical manifestations of the action of membranotropic preparations, high effectiveness of therapeutic action of mildronat as compared with phosphaden. The results obtained can serve as a foundation for the usage of the preparations in complex treatment of patients with severe chemical burns of the eye.
