Risk Stratification for Embolic Events in Surgical Patients with Left-Sided Infective Endocarditis
Abstract
The purpose of the study This study was aimed to determine the structure and identify risk factors associated with the development of embolic events in surgical patients with left-sided infective endocarditis. Materials and methods The cohort includes 238 patients with left-sided infective endocarditis who underwent valve replacement surgery. All thromboembolic events which have occurred before, during and after surgery were studied. The influence of the basic epidemiologic, clinical, microbiological, echocardiographic, and laboratory data on the cases of embolism was analyzed. Results and their discussion In-hospital mortality in general cohort was 9.24%; in the group of patients with embolic events it was 11.54%, and in the event-free group it was 8.60%. The mortality in the sub-group with pre-surgical embolic events was 8.33%, and in the sub-group with post-surgical embolic events it was 18.75% (all deaths occurred in this sub-group were related to embolisms). In patient group with embolic events and in the event-free group mitral valve impairment was reported to occur in 44.23% and 31.72% of cases, respectively. Vegetations were reported in 93.28% of patients. Transesophageal echocardiography showed higher sensitivity in comparison with transthoracic echocardiography for vegetations located on mitral valve only (p≤0.05). The relation was confirmed between pre-surgical embolic episodes and bulky mobile vegetations (p<0.05). In 43.75% of cases thromboembolic episodes in post-surgical period took place after both mitral and aortic valves replacement, most post-surgical embolisms occurred within the first three days after the surgery. Conclusion Major risk-factors associated with pre-surgical embolic events in patients with left-sided infective endocarditis were: active infective endocarditis, mitral valve lesion, and large mobile vegetations. The embolic events which have occurred before surgery did not affect hospital mortality. Intra- and post-surgical embolic events in left-sided IE patients were not related to the risk factors associated with pre-surgical embolisms and were found to increase in-hospital mortality risk. The highest risk of postoperative embolism appeared to be in early post-surgical period. Key words Infective endocarditis, surgical treatment, embolic events, risk factors.

The Role of Microsomal-Monooxygenase System of Liver and Indirect Electrochemical Oxidation of Blood in the Formation Mechanism of Endogenous Intoxication Syndrome in Animals with Experimental Bile Peritonitis
Abstract
Relevance On the background of growth in the number of patients JCB problem ha is of particular relevance. Ha leads to the development of systemic inflammatory response, which is accompanied by excessive generation of cytokines, are able to inhibit the activity of cytochrome P-450-dependent MOS liver, responsible for the biotransformation of endogenous compounds. The purpose of the study Is to evaluate the modulating effect NGH on MOS liver in experimental. Materials and methods Study of cytochrome P-450-dependent MOS liver conducted on 120 mongrel rats-males, weighing 160-200, by the method of A.I. Archakov (1975) and I.I. Carosino et al., (1977). The protein content in a fraction of microsomes determined by O. Lowry (1951). The number of microsomal cytochrome P-450 were determined by the method of T. Omura, R. Sato (1964). State MOS liver was estimated by the rate N-demethylation of antipyrine and gidrauxilirovania aniline (I.I. Karuzina, A.I. Archakov, 1977). Results and their discussion Experiments indicate the development of the syndrome of EI in animals with ha oppression antitoxic function of the liver. Introduction of 0.03% solution NGH causes a significant increase of cytochrome P-450 and b5, indicating that it permantently activity, at the same time as the use of 0.1% solution NGH causes a decrease of their content, indicating fermentarii effect. Conclusion Obtained result is of considerable clinical importance, because the biotransformation of many of the antibiotics used in the treatment of acute abdominal pathology occurs almost exclusively microsomal enzymes hepatocytes that against bacterial infection there is a significant risk of overdose, therefore, the use of 0.03% solution NGH can contribute to the induction of cytochrome P450 liver

The Ways to Study the Effectiveness of Various Schemes of the Antibiotic Prophylaxis of Postoperative Septic Complications, and the State of the Lymphatic System Drainage in the Experimental Postoperative Period
Abstract
The purpose of the study Another option, proposed by the author, is a parallel combination of antibiotic prophylaxis and varying lymph stimulation. Materials and methods The study was conducted on 36 Wistar male rats. The effectiveness of antibiotic prevention in the conditions of new model of infectious complications in surgical area was studied in groups of 6 animals. Results and their discussion It is experimentally proved that for a given simulation of postoperative complications ABP is really effective, i.e. the number of operations undergone by animals increases. Means, this model takes place on existence and can be used to study various methods of ABP. The condition of a lymphatic drainageis oppressed during the development of pyoinflammatory complications in regional and distal lymph areas concerning a surgery zone. Conclusion Antibiotic dose used in the ABP does not affect the frequency of development of SSIs (p> 0,05), but severity of other complications depends on it (peritonitis, death) p≤0,05. Combining it with lymphostimulation using minimal doses improving its efficiency p ≤ 0,05. The isolated lymphostimulation in the experiment is prevention of development of SSIs

Contact Ultrasonic Lithotripsy in the Lumen of the Common Bile Duct
Abstract
Relevance Choledocholithiasis occurs in about 18-36% of patients with calculous cholecystitis, and in elderly patients is more common than in the young. Available methods of laparoscopic common bile duct revision enough laborious and not always successful. Using endoscopic papillosphincterotomy subsequently leads to disruption of the reflex sphincter function and development of papillary insufficiency, also does not guarantee the removal of large stones. Consequently, the need and urgency of finding solutions to low-traumatic removal of stones from the common bile duct in individuals at high risk of surgical intervention, especially when the residual choledocholithiasis. The purpose of the study To decrease trauma treatment of choledocholithiasis using contact ultrasound lithotripsy in the lumen of the common bile duct. Materials and methods To perform lithotripsy in the lumen of the common bile duct was created waveguide original design. In in vitro experiments produced crushing stones extracted from the gall bladder of patients operated on for gallstones, various compositions. In in vivo experiments used 20 adult mongrel rabbits after modeling cholelithiasis by replanting calculus gallbladder voiced its cavity for 4 minutes. To study the pathological effects of these parameters ultrasound articulated wall of the intestine and the diaphragmatic surface of the liver for 3-7 minutes. Results and their discussion It was established experimentally that the optimal parameters for performing lithotripsy: output power 35%, from 40 to 65 watts, 26500-26700 Hz frequency. More mineralized, pigment stones are fragmented faster than cholesterol, medium and low-mineralized stones. In vivo experiments, in all cases in the cavity of the gallbladder found the remains of the calculus in the form of small fragments of sizes up to 0.5 mm. Pathological changes in irradiated tissues is minimal and completely leveled to 14 days after exposure to ultrasound. Conclusion Thus, in an effort to preserve the sphincter apparatus major duodenal papilla, the proposed waveguide can be successfully used in the treatment of gallstone disease without the threat of deep soft tissue injuries. Design of the waveguide allowsduring laparoscopic surgery to penetrate into the lumen of the common bile duct stones and make the fragmentation that would significantly reduce traumatic intervention.

New Methods of Treatment of the Diffused Peritonitis
Abstract
Despite the achievements of the modern medicine, diffused peritonitis until the present time remains the urgent problem in the emergent abdominal surgery. According to the data of the leading Russian and foreign clinics, mortality rate in this pathology in the last decades has not showed any reduction tendency and varied in the range of minimum 20-30%, achieving at maximum 50-70%. The article presents analytical review of new approaches to the treatment of the diffused peritonitis. The authors describe in detail their own developed three methods of treatment of peritonitis and indications for their application. In traditional (semi-closed method of treatment) sanitation of the abdominal cavity was conducted with the use of immobilized forms of sodium hypochlorite in the gel of carboxymetilcellulose. Deponent of the antiseptic prolongs its bactericidal action, while the gel of carboxymetilcellulose prevents the gluing of the organs’ surfaces , by which reduces the severity of adhesive process. In surgical-laporoscopic method of treatment video-endoscopic sanitations of the abdominal cavity were done by pulsating irrigation of antiseptic. To close the defects of the abdominal cavity in semi-open method of treatment there was used large-net endoprothesis made from polypropylene. Between the edges of the wound there was left diastases, at which intra-abdominal pressure was below 15 mm. of mercury column. For selection of the appropriate method of treatment there was used the original scale of quantitative evaluation of factors, influencing lethality rate of patients. It was proved that semi-closed method of treatment is reasonable to use in patients without signs of the abdominal sepsis, while programmed video-laparoscopic sanitations should be used in cases of abdominal sepsis without poly-organic dysfunction and intra-abdominal pressure below 20 mm. of mercury column, programmed surgical sanitations are indicated for patients with severe abdominal sepsis with poly-organic insufficiency and abdominal hypertension above 20 mm of mercury column. Introduction of new methods of treatment to practice enabled to decrease the number of postoperative complications by 10% and lethality – by 8,2%
