[Effect of hyperbaric oxygenation on pulmonary function, acid-base state and the blood gas composition in mitral heart defect patients].

Improvement of external respiration, acid-base balance and gas composition of blood was noted after application of a complex of therapeutic measures in combination with hyperbaric oxygenation. The fact that positive changes in external respiration were less pronounced in patients with stenosis of the left venous orifice than in those with mitral incompetence may evidently be explained by the presence of long-term and high pulmonary hypertension and certain increase in the volume of blood in pulmonary circulation in noncorrected stenosis of the left venous orifice. A decrease in metabolic acidosis is noted, which is a complication leading to deterioration of systemic and peripheral hemodynamics, inhibition and myocardial function and blood supply to the brain.

[Effect of hyperbaric oxygenation on the circulatory function in rheumatic mitral valve disease].

The effect of a hyperbaric oxygenation course (10-14 exposures, one exposure daily at 0.7-1.0 ATA) upon the circulation function was studied in 61 patients with rheumatic mitral valve disease combined with systemic circulation insufficiency. The obtained results (reduction of the heart volume, acceleration of the blood stream within the heart and the body, increase of the stroke index, of the blood flow in the muscles of the extremities, reduction of the arterial and central venous pressure) demonstrate that the contractility of the myocardium and redistribution of the cardiac output between separate vascular regions is improved under the effect of hyperbaric oxygenation. The authors suggest that the increase of contractility in the right or left heart predominantly depends on the prevalence of mitral stenosis or circulatory insufficiency.

[Bacterial toxic shock in urological diseases].

It is a review of present-day and historical aspects of bacterial toxic shock arising in urological setting. It is noted that conditions of its onset are changing, therapeutic approaches undergo revision, critical care facilities are updated. Among the causes of this complication the authors single out endoscopic procedures, transurethral interventions in the presence of infectious process, hospital infection, long stay at hospital. Forty-eight cases of bacterial toxic shock are reviewed in relation to classification, causes of development, treatment, bacteriological evaluation.

[The effect of psychoemotional stress on kidney function].

Psychoemotional stress, like other kinds of emergency states, is accompanied by renal functional changes and accumulation of biologically active substances in the human body, among which middle molecular oligopeptides are classified. In inadequate or untimely premedication, an operative intervention of any scope occurs initially under unfavourable conditions due to accumulation of biologically active substances in blood and decrease in renal functions. The proposed method of preoperative measurement of the middle molecular oligopeptides and their correlations in plasma and urine may become an indirect indicator of premedication adequacy and a screening test of renal function.

[The characteristics of proteinuria during intensive physical loading].

Intensive physical exercise result in certain changes in the body, kidneys in particular. A total of 23 highly qualified sportsmen were investigated for plasma proteins in the urine before and after the graded bicycle ergometry. The impairment of renal reabsorption due to physical load was evidenced by significant amounts of albumin in the afterload urinalyses of all the examinees, and the appearance of IgG in urinalysis of 6 sportsmen in comparison to the urinalysis before the exercise which reported insignificant levels of albumin in 6 subjects only.

[Effect of intensive physical loads on renal function].

The purpose of the study was to evaluate the extent of renal functional disorders, developing in response to muscular exercise of varying intensity and duration in 64 professional athletes, aged 17 to 26 years. Comparative characteristics of 131I-hippuran kinetics through the urinary tract both at rest and after "acute" (single) and chronic (many years') physical exercise are obtained. There was a direct relationship between effective renal blood flow and the magnitude of muscular exercise. It is demonstrated that post-exercise renal changes disappear without trace, while individuals, exposed to extreme muscular stress for long periods of time, i.e. the professional athletes, may develop irreversible functional changes. Impaired renal function can hardly be attributed to the emergence of yet another compensatory mechanism, for such notions as 'compensation' and "persistent impairement of functional potentials of an organ" are mutually exclusive.

[The detection of latent circulatory and respiratory failure in urologic patients at the prehospital stage].

Elderly patients admitted to urological hospitals and departments with increasing frequency have the disease complicated with age-specific and associated circulatory and respiratory affections. Occasionally, these complications are not clinically evident, but may acquire unwanted decompensated course. Subclinical forms of circulatory and respiratory insufficiency can be managed using relatively simple methods of functional assessment applicable in outpatient setting. Recommendations are provided on operative preparations which can be made at home or in outpatient department thus reducing the cost of hospital stay.

[The disseminated intravascular coagulation syndrome in urological diseases].

The authors consider causes and mechanisms underlying DIC syndrome onset in complications of urological diseases. The syndrome may originate from azotemia-induced intoxication, injury to the kidneys and urinary tracts, complications of surgical interventions. Etiologically and pathogenetically validated approaches to DIC syndrome treatments, their regimens, combinations and dosages are presented.
