[Infectious endocarditis as a surgical problem in Russia].

Infectious endocarditis (IE) is mainly a surgical problem and requires an integration of efforts of specialists of different fields for its treatment. Successful treatment of this severe disease is to be based on the early diagnosis and early operation. So IE should be estimated as a surgical pathology and this nosological form must be included in all manuals on general surgery and studying infectious endocarditis must be included in the programs of training doctors at surgical series of lectures. Such interpretation of this question will change doctors' mentality and will lead to the earliest admission of the patient with this pathology to specialized cardiosurgical hospital and will allow to avoid severe disabling complications of IE, to increase the number of valve-saving operations and to improve prognosis in the treatment of this disease.

[Prevention of prosthetic heart valve infection].

Fourty patients with primary and secondary infective endocarditis of the native heart valves as well as patients with rheumatic heart diseases not complicated by infective endocarditis were operated upon in the clinic from 1996 till 1998. The prosthetic heart valves in which the tissue cuff was sutures by blanket suture along the perimeter with a silver thread were implanted to 25 patients. In the other 15 patients (a control group) prosthetics were made using unchanged construction of the prosthesis (without the silver thread). Patients with valve prostheses sutured with the silver thread had smooth postoperative period. They had no prosthetic endocarditis either at the early or at late postoperative periods. In 3 patients of the control group infective endocarditis of the valve prosthesis developed at different periods after operation. All of them were reoperated. The authors consider that defense of the tissue cuff of the prosthetic valve with the silver thread allows risk of the development of prosthetic endocarditis to be substantially reduced. In the cases described it was completely avoided.

[The early diagnosis of postoperative infectious complications in heart surgery patients].

Great surgical aggression in operations on the heart and resulting immunodeficiency create prerequisites for the appearance and grave course of infectious complications. The authors have analyzed results of operative treatment of 100 patients with acquired valvular diseases. It has been established that low parameters of the resistance index of organism (RIO) before operation can be estimated as an unfavourable prognostic sign of the development of infectious complications. The RIO dynamics at the postoperative period in many aspects reflects the character of its course. RIO and the indices of the adaptation reaction show the degree of intoxication, make the clinical estimation objective, allow the assessment of efficiency of therapy and correction of medical prescriptions.

[Hospital infection and some aspects of its immunoprophylaxis].

The review deals with the causes and main agents of the hospital infection occurring in surgical units. Special attention is given to the formation of the hospital isolate of the agent. A method of prevention of postoperative infective complications by vaccines prepared of these particular isolated has been proposed.

[The organization of the donation of autologous blood and its components in cardiac surgery].

The article analyzes an experience with the organization of autodonation of blood and its components in surgical treatment of 305 patients with congenital and acquired defects and ischemic heart disease. Methods of plasmacytapheresis and cryopreservation used at the terms from 3 days to 12 months before operation allowed storage of the autologous components of blood in 41.2% of the patients having indications for autodonation. In 29.1% of the observations the autotransfusion media were reserved under the outpatient clinic conditions which resulted in shorter terms of treatment at the hospital. The number of unfavorable reactions during the donation in patients did not exceed analogous parameters in regular donors. Autohemotransfusions 3-5 times reduced the volume of transfusions of the allogenic blood components and they were completely avoided in 20.1% of the patients.

[Cardiac abscesses].

The paper analyzes the experience in treating 75 patients with cardiac abscesses of various sites. Abscesses complicated the natural history of infectious endocarditis in all patients. The clinical features of cardiac abscesses are shown to be related to the stage of the destructive process. Echocardiography, follow-up analysis of ECH, PhCG and overall clinical data are demonstrated to play a role in their diagnosis. The paper discusses the specific features of surgical intervention into the heart if abscesses are present. Out of 75 patients who have been operated on for abscessing infectious endocarditis, 53 have had an operation and survived.

[Intensive plasmapheresis: complications and their prevention].

Upon the analysis of 246 plasmapheresis sessions performed for autoplasma provision, the correction of the blood rheology and the decrease in endogenic intoxication of 216 patients, it was stated that the frequency of various reactivity and complications comprised 12.9%. The causes of these complications and the means of their prevention were analyzed.
