Artificial Blood Circulation

Achilles Mario Dogliotti, the surgeon station wagon, the author a set of new interventions in neuro, onko-and a heart surgery performed the first-ever successful operation with use of the cardiopulmonary bypass on August 7, 1951. Dogliotti paid special attention and fruitfully was engaged in surgery of a liver and biliary tract. He developed a way of removal of bile in cases when it is impossible to use the general bilious channel with a resection of a part of the left share of a liver (Dogliotti’s way); operation at damage of outside bilious ways with sewing together of a channel on a rubber tube and removal of its disteel end through a front wall of a stomach and a front belly wall outside (Dogliotti’s operation); a way of drainage of biliary tract with carrying out a drainage tube with several side openings outside through the general bilious channel in a duodenum (Dogliotti’s way). A number of interesting innovations offered Dogliotti in cardiovascular surgery. So, it possesses a way of prosthetics of the mitralny valve the pericardium rag on a leg entered into a heart cavity through its wall and attached between the papillary muscles (Dogliotti’s method). He offered some modifications of operations at the inborn and acquired heart diseases. For partial compression of large vessels of Dogliotti developed the tool having three working bransh (a surgical clip of Dogliotti-Vishnevsky), I developed the device for artificial blood circulation and some other original tools for cardiovascular surgery. One of first-ever it made operation with use of extracorporal blood circulation in clinic. Also its researches and clinical application of a moderate and deep hypothermia in heart surgery are known. A. Dogliotti “The treatise on anesthesiology” (1952), “The operational equipment” (1956), “Surgery of bilious ways” (1958) published about 300 scientific works on surgery, including the monograph “Surgical Semiotics and Diagnostics” (1948). I created a number of original tools for cardiovascular surgery, I designed the device for artificial blood circulation, I offered some modifications of operations at the inborn and acquired heart diseases. One of first-ever I made operation in the conditions of extracorporal blood circulation.

Hydrogen Peroxide Generation

The search of the prognostic criterion of postperfusion period course is performed. The informativity of one of the nonspecific organism protection indices luminoldependent chemoluminescence of blood is estimated. Spontaneous chemoluminescence expresses phagocytes activity by the intensity of hydrogen peroxide generation. Stimulated chemoluminescence allows to establish the functional leykocytes reserve. As many as 54 patients with heart diseases are examined in dynamics. The increase of both of chemoluminescence types is observed in the cases of the uncomplicated course, during artificial blood circulation and after operation. The sharp decrease of indices with reduction of the stimulated chemoluminescence level below spontaneous level is noted during complications.

Cardioplegic Solutions

Relevance. Surgical treatment of cardiovascular diseases with the use of artificial blood circulation is associated with the need to protect the myocardium. Various cardioplegic solutions are widely used in cardiac surgery to stop and protect the heart. Currently, a significant number of mixtures of drug solutions are used in "open" heart surgery. However, not all of them have been officially registered as cardioplegic solutions and not all have the appropriate indications in the instructions for medical use of the drug, which jeopardizes the safety and quality of medical care for patients. Goal. To study the pharmaceutical market of registered drugs for cardioplegia and to estimate the share of heart operations with the connection of artificial circulation performed without the use of officially registraited drugs for cardioplegia. Materials and methods. The following methods were used in the work: content analysis, statistical, marketing, graphic. The main information sources were: the State Register of Medicines; statistical indicators of surgical interventions in cardiac surgery, information on public procurement of medicines, instructions for the medical use of medicines, regulatory documents. Results. This study presents the results of a marketing analysis of the pharmaceutical market of drugs officially registered for cardioplegia. Three medicines have been registraited in Russia, which, in accordance with the instructions for use, can be used during surgical interventions in the quality of cardioplegic solutions. According to the ATC classification, all of them belong to the subgroup of the fifth level B05XA16 "Cardioplegic solutions". For the period 2018-2020. the volumes of purchases of cardioplegic solutions for the needs of medical organizations have been established and the volumes of drugs for surgical intervention in cardiac surgery during operations on the "open" heart have been determined. The comparison of morbidity rates and the estimated number of surgical interventions of the cardiac surgery service based on the data of public procurement of drugs for cardioplegia, revealed a discrepancy between the volumes of purchased cardioplegic solutions and the care provided. The data analysis shows that at least 23 thousand cardiac surgeries in Russia are performed annually without the use of registraited medicines for cardioplegia. Conclusion. When performing surgical interventions on an "open" heart with the connection of artificial blood circulation, it is necessary to use cardioplegic solutions that have an official indication in the instructions for medical use, in order to ensure the safety of patients and to perform medical interventions of appropriate quality.

Artificial Blood Circulation

The article considers evaluation of indicators of inflammation, antioxidant defense and myocardium ischemia in patients with ischemic heart disease exposed to coronary bypass surgery using artificial blood circulation or on functioning heart. The sampling included 96 patients distributed to two groups. The first group included 84 patients (81% of males, average age 62,2±7,7 years) exposed to coronary bypass surgery in conditions of artificial blood circulation. The second group included 12 patients (91,7% of males, average age 59,8±8,0 years) exposed to coronary bypass surgery on functioning heart without artificial blood circulation. The study demonstrated significant increasing of level of interleukin-6 in patients with ischemic heart disease after application of coronary bypass surgery with extra-corporal blood circulation that confirms high activity of inflammation factors at the given disease. The reconstructing operations on hearts in conditions of artificial blood circulation are accompanied by decreasing of concentration of superoxiddismutase. At that, the level of analyzed bio-marker remains as compared with operation on functioning heart. This occurrence testifies activation of oxidative process and intensified consumption of as factor of antioxidant defense in the course of direct re-vascularization of myocardium. The concentration of troponin increases in post-operational period of reconstructing operation but differences are unreliable when analyzed groups are compared.
