Заболевания сердца и сосудов, ассоциированные с атеросклерозом, на протяжении 20 лет являются лидерами среди причин смертности людей во всем мире. По официальным данным Глобальных оценок состояния здоровья ВОЗ из Информационного Бюллетеня ВОЗ от 09.12.2020, именно они занимают первую позицию в списке десяти ведущих причин смертности [1]. Что касается Узбекистана, вопросы заболеваемости и смертности от сердечно-сосудистых заболеваний были предметом рассмотрения Президентом Узбекистана Ш.М. Мирзиёевым на видеоселекторном совещании, прошедшем 9 ноября 2021 года и посвященном проблемам заболеваемости и смертности населения страны от этой патологии, которая достигла величины в 53% от общей смертности [2].
The aim of the study is to development of an algorithm for managing pregnancy and childbirth by studying the functional state of the mother-placenta-fetus system in pregnant women who have undergone COVID-19 in different trimesters of pregnancy.
The object of the study was 105 pregnant women who, were treated at the Samarkand Regional Perinatal Center and a specialized maternity center for pregnant women with COVID-19
Тhe scientific novelty of the research consists of the followings: for the first time in pregnant women infected with COVID-19, a relationship was established between the course of pregnancy, childbirth, the postpartum period and the development of complications depending on the trimester and severity of the disease; a direct correlation has been established between the state of the vessels of the mother-placenta-fetus system (resistance and pulsation indices, Endothelin-1 indicators), disorders in the hemostasis system (D-dimer, platelet aggregation) and the clinical course of the disease in pregnant women who underwent COVID-19; it has been established for the first time that the developed scale for assessing risk factors for non-developing pregnancy in women infected with COVID-19 (age, BMI, obstetric history, gestation period, hemostasis system status, endothelial function and severity of the disease) can serve as a prognostic marker of the degree of risk of pregnancy complications; it was proved for the first time that the choice of effective therapy for restoring hemodynamics in the mother-placenta-fetus system, in women who underwent COVID-19 at different stages of pregnancy, leads to a decrease in the number of thrombophilic complications.
Implementation of the research results. The results of the scientific research were introduced into the practical activities of the Samarkand Regional Perinatal Center by Order No. 128/1 of 01.09.2022 and the Samarkand City Maternity Complex No. 1 by order No. 58/1 of 03.10.2022. In pregnant women who underwent COVID-19 at different periods of pregnancy, changes in the mother-placenta-fetus system were determined using simple and effective research methods, such as ultrasound and Dopplerography, and this saved 53,000 soums; obstetricians and gynecologists, as well as neonatologists and therapists, are needed to diagnose signs of complications in the echocartin, that is, it has been proven that there is no need for other highly qualified specialists for this, due to the lack of need to train new personnel, state budget funds have been saved. With early detection of disorders in the hemostasis system in pregnant women with COVID-19: the period of stay of patients in the hospital was reduced from 10.5 days to 7.5 days and the number of hospital bed days was reduced; due to the reduction of the period of stay in the hospital for several days, the number of necessary drugs was reduced (on average, drugs are used for 1 day in the amount of 130,000 soums). Examination of pregnant women infected with viral diseases using simple and effective research methods such as ultrasound and Dopplerography served to save 85,000 soums: in the early stages up to 16 (10-11 weeks. - fetometry), 19-21, 32-34, 38-40 weeks of pregnancy; due to the absence of the need to use other research methods, it was possible to reduce costs by 23.5%; early detection of changes in the hemostasis system and endothelial dysfunction using fast, budgetary and effective research methods, contributed to the prevention of possible pregnancy complications, as well as the absence of the need to use long-term and expensive research methods, and this saved 106 000 soums: the coagulogram was checked in 105 (100%) patients, time was saved and efficiency was increased; endothelin-1 was also determined in 105 (100%) patients, efficiency was increased by 78.6%.
Improving the functionality of blood circulation in the uteroplacental and fetal-placental systems, a comprehensive analysis of possible complications during pregnancy and childbirth in women who have had viral infections, improving diagnostic, preventive and prognostic measures for managing pregnancy and childbirth contributed to the birth of live, full-term and healthy newborns in women who experienced COVID-19 during pregnancy, as well as a decrease in maternal mortality and perinatal mortality, 43% of women underwent rehabilitation in the postpartum period, 23.8% of women who underwent severe COVID-19 improved their quality of life.

In modern abdominal surgery, one of the current areas for research continues to be the improvement of various options for plastic surgery of postoperative hernias. More than 2,100,000 operations for ventral hernia are performed annually in the world, and 42% of them are postoperative hernias. In recent years, there has been a clear trend toward the expanded use of various types of biological meshes in hernioplasty. “A pooled analysis of seven PCSTAR studies for incisional hernias using retromuscular mesh showed a hernia recurrence rate of 5.7%”[1]. The use of standard surgical interventions such as alloplasty in the onlay position does not solve the problem of early postoperative complications: seroma discharge, mesh migration, adhesive disease, high frequency of hernia recurrence, etc. At the same time, hernia repair with local tissue creates the problem of increased intra-abdominal pressure and late complications in the form of recurrent hernias. “An increase in postoperative intra-abdominal pressure leads to multiple organ failure, then abdominal compartment syndrome, and even death.” [2]. Currently, there is no consensus on the surgical approach for giant postoperative abdominal wall hernias, and therefore the need to continue to develop new technologies and improve There is no doubt about the tactics. In world practice, at present, the most relevant studies continue to be studies aimed at studying the morphological and functional aspects of recurrent postoperative ventral hernias; electron microscopy reveals ultrastructural destructive changes in skin cells, aponeurosis and muscles, which indicates morphofunctional insufficiency of abdominal wall tissues; issues of cell engineering are discussed new innovative materials, experimental studies are being carried out on animals testing the biotechnical properties, texture and elasticity of new polymers, research is being conducted on open approaches with division of the posterior component with the release of the transverse abdominis muscle and a retrograde mesh, robotic operations have begun. Modern aspects of the development of domestic healthcare include many measures aimed at improving the results of treatment of patients with postoperative ventral hernias and associated pathological conditions through the introduction of modern principles of intensive care and surgical tactics. The development strategy of New Uzbekistan for 2022-2026 in seven priority areas includes tasks to improve the quality of provision of qualified medical services to the population[3]. The implementation of these tasks, including by optimizing tactical and technical approaches to the choice of hernioplasty method, as well as the development of methods for the prevention of purulent-inflammatory complications in the field of alloplastic material, is one of the current areas of abdominal surgery and medicine in general, due to the high medical and social the significance of this pathology.

As a result of studies conducted around the world to increase the effectiveness of alloplasty for postoperative ventral hernias and reduce the risk of complications in the postoperative period, a number of scientific results were obtained, including: it was determined that patients who underwent reconstruction of the abdominal wall have an increased risk of postoperative respiratory failure, understanding the epidemiology of this complication can improve prevention (the Division of Plastic and Reconstructive Surgery, Department of Surgery, Oregon Health & Science University, USA); It has been proven that the larger the hernia, the higher the risk of early surgical complications, including such as respiratory decompensation, since hernias often increase in size over time, delaying surgery can lead to an increase in the size of the hernia and, therefore, a greater risk of complications (CentreforDigestiveDiseases, KarolinskaUniversityHospital, Stockholm, Sweden); it has been shown that the ratio of the hernia volume to the volume of the abdominal cavity <20% is an independent factor in tension-free closure, which justifies the interest in preoperative volumetry to adapt the tactics of surgical care (Servicedechirurgiegénérale, digestiveetendocrinienne, CHU LyonSud, HospicescivilsdeLyon, France); It has been determined that in patients undergoing elective laparoscopic hernia repair, predictors of mortality are older age and certain concomitant diseases: congestive heart failure, pulmonary circulatory disorders, coagulopathy, liver disease, metastatic cancer, neurological disorders and paralysis (Department of Surgery, College of Medicine, University of Oklahoma, Tulsa , USA); Older age, ascites, preoperative renal and pulmonary insufficiency have been found to be independent predictors of 30-day mortality, and in the presence of these risk factors, conservative treatment should be seriously considered (Department of Surgery, University of Kentucky College of Medicine, Lexington, USA); The American College of Surgeons (ACS) Universal Surgical Risk Calculator has been shown to accurately predict thirty-day outcomes, including major complications: venous thromboembolism, medical morbidity, surgical site infection, unplanned reoperation, mortality, and length of hospital stay (Department of Plastic Surgery, Brown University and Rhode Island Hospital, Providence, USA). At the present time in the world, the most relevant research in surgery continues to be the development of new methods of hernioplasty for large and giant ventral hernias, each of which has its own pros and cons depending on the complexity of implementation, the risk of postoperative complications and relapse, large randomized clinical trials are being conducted, comparing existing methods of traditional hernioplasty with laparoscopic access and robotic surgery, which has become increasingly widespread in the last 10 years, a search is being made for new synthetic and biological materials developed for the production and use of composite meshes that have the necessary strength and the ability to prevent fatal local complications in a contaminated environment. However, despite technical advances in this field, no modern hernia repair method or prosthesis meets all the requirements. One of the key problems is that existing synthetic endoprostheses do not have sufficient elasticity, resistance to infection, high mechanical strength and integrity over a long period of time. Further research into these clinical aspects will undoubtedly improve the current understanding of the capabilities of biocompatible endoprostheses and will make it possible to develop an optimal method for their placement during allohernioplasty. The degree of knowledge of the problem. The current period of development of abdominal surgery is characterized by an emphasis on the problems of the effectiveness of introducing new installation methods and techniques for attaching bioprostheses, options for various suture materials to determine the most promising directions for the development of these technologies [5]. Researchers led by BittnerR.[6] (2019) state that a giant postoperative abdominal wall hernia, the maximum diameter of which exceeds 12 cm or the ratio of the volume of the hernial sac to the abdominal cavity more than 20%, is difficult to treat, with a high recurrence rate and a large number of complications. One of the most challenging problems is that after the hernia contents return to the abdominal cavity, postoperative intra-abdominal pressure will increase, leading to multiple organ failure, then abdominal compartment syndrome (ACS), and even death. There is currently no agreement on the surgical approach for these giant incisional abdominal wall hernias. To prevent recurrences, some articles recommend placing the hernia mesh in the sublayer position and or linings (KirkpatrickAW.)[7]. According to CornetteB.[8], to prevent recurrence, it is recommended to place the hernia mesh in a sublayer or underlay position, and to achieve better mesh expansion, a component separation technique (CST) may be a suitable solution, but with a significant risk of complications and recurrence. JensenKK, et al. believe that truly successful giant hernia repair requires effective bridging or augmentation that will prevent recurrence with an acceptable risk of complications[9]. Another pressing issue in abdominal surgery is that patients with incisional hernias are extremely difficult to treat due to a number of factors including obesity, previous hernia repair, previous mesh placement, domain loss, and other variables.
The approach to patients with incisional hernias has changed significantly over the past 20 years due to both advances in mesh technology and surgical approaches. Key factors for successful outcome include modification of risk factors preoperatively, such as smoking cessation and weight loss, selection of mesh appropriate for the type of hernia and planned mesh location, and wide mesh coverage beyond the hernia defect. New techniques such as transabdominal muscle release and component separation with retrograde mesh placement and robotic approaches to abdominal wall hernia are increasingly being used in these patients[10]. Recent years have seen an increase in the number of biological meshes available for abdominal wall hernia repair. Biological meshes typically consist of materials obtained from humans, pigs, or cattle. The rationale for using biological meshes is that they can act as a scaffold for the growth of natural tissues. In addition, there are absorbable synthetic meshes that have properties similar to those of biological meshes, but with theoretically less risk because they are not derived from animal or human material. The choice of mesh for a ventral hernia depends on many factors, which include both the properties of the mesh and its location, for example, whether it should be placed intraperitoneally, preperitoneally, or retrorectus. BaierKF[11](2021) believes that the guiding principle should be to avoid placing uncoated polypropylene mesh in an intraperitoneal location where it may be in direct contact with internal organs. In addition, the type of hernia defect is another risk factor, such as whether the wound is clean or dirty, and whether the repair is performed with a bridge or abutment. Lightweight or biologic meshes to bridge the defect should be avoided due to increased recurrence rates. Holihan JL [12] (2016), Hodgkinson JD [13] (2018) believe that the principle of anatomical restoration to achieve a reliable, tension-free repair with reinforced mesh reduces the incidence of early postoperative complications and late recurrence of hernia compared with bridging mesh. The analysis of the literature concerning the theoretical aspects and clinical experience of using technologies for improving modern synthetic and biological prostheses that can provide a better plastic effect, as well as methods for preventing recurrence of ventral hernias, indicates that this is one of the priority areas in modern abdominal surgery. An unresolved issue remains the choice of the optimal endoprosthesis, which is highly effective and meets international standards for such properties as biological inertness and mechanical strength, as well as the method of positioning the mesh in relation to the layers of the abdominal wall. Considering that many of the allohernioplasty methods used today are not without drawbacks, the current direction is the development of new methods of repair for giant ventral hernias and methods for the prevention of postoperative complications in conditions of a contaminated wound, with justification of their effectiveness in a clinical experimental study. The connection between the dissertation research and the research plans of the research institution where the dissertation was completed. The dissertation research was carried out within the framework of the research work plan of the State Institution “RSNPMCH named after. acad. V. Vakhidov" under the project AL-422105574 "Development of new biocompatible mesh implants made of composite materials for reconstructive surgery of abdominal and diaphragmatic hernias" (2022-2024).
The purpose of the study is to improve the results of surgical treatment of large and giant postoperative ventral hernias by introducing new laser technologies and improving the tactical and technical aspects of surgical treatment. Objectives of the study: to study the structure of immediate complications after various types of prosthetic plastic surgery; to clarify the influence of obesity factors, primary or repeat hernioplasty on the incidence of immediate and long-term complications; to evaluate the role of the immediate complicated course of the postoperative period in the incidence of long-term complications of hernioplasty; to improve the technical aspects of alloplasty for large and giant postoperative ventral hernias (POVH); to improve the technique of photodynamic therapy (PDT) of the wound surface after prosthetic plastic surgery; to study in an experiment the effectiveness of using the proposed technique of alloplasty and PDT; evaluate the morphological features of the condition of tissues during prosthetic plastic surgery using the proposed method; in a comparative aspect, evaluate the clinical effectiveness of the proposed alloplasty options in the immediate and long-term periods. The object of the study was the results of allohernioplasty in 448 patients with extensive (large) and giant POVH, who were operated on at the surgical department of the 1st clinic of the Samarkand State Medical Institute in the period from 2012 to 2021, as well as experimental animals on which the effectiveness was assessed developed a technique for prosthetic repair of postoperative ventral hernias and applied the technique of photodynamic therapy.
The subject of the study is to analyze the effectiveness of the developed alloplasty of postoperative ventral hernias and intraoperative photodynamic therapy in abdominal surgery in experiments and in the clinic. Research methods. To achieve the goal of the study and solve the assigned problems, general clinical, instrumental, biotechnological, experimental, histomorphological, microbiological and statistical research methods were used. The scientific novelty of the study is as follows: it was established that the need for extensive tissue mobilization and, as a consequence, the intersection of lymphatic capillaries during implantation of the prosthesis in the onlay position, as well as the lack of sufficient resorption function of the hernial sac in the inlay position causes a high risk of the formation of clinically significant seromas; It was determined that with prosthetic hernioplasty, along with the volume of the defect, the type of plastic surgery and the degree of obesity, the most significant predictor of the risk of developing immediate complications is the factor of re-intervention in case of recurrent hernia with the presence of a “dormant infection” hidden in the remaining ligature granulomas or scar tissue; the structure and clinical features of the course of long-term complications of hernioplasty for giant and extensive hernias were clarified, taking into account the results of the immediate postoperative period, as well as the option of fixing the prosthesis, primary or repeated hernioplasty and the degree of obesity; the method of surgery for large hernias of the anterior abdominal wall has been improved, characterized by a combination of factors such as the formation of tension-free prosthetic repair, preservation of local resorptive function to prevent the development of fluid accumulations and reducing the risk of infection; the method of preventing the development or progression of wound infection during alloplasty of ventral hernias has been improved, aimed at enhancing the antibacterial effect and stimulating reparative activity through the photosensitizing and photodynamic effect of low-energy laser radiation; It was determined in an experimental model of prosthetic plastic surgery that the proposed method of fixing the prosthesis in combination with the use of the effect of photodynamic therapy through laser radiation helps to enhance reparative processes with a reduced risk of wound complications; It has been proven that all methods of antiseptic exposure and laser stimulation of the wound surface after prosthetic plastic surgery enhance preventive measures against the development of local infection, but are ineffective in the case of an already developed purulent-inflammatory process against the background of the use of alloplastic material. The practical results of the study are as follows: it has been determined that the implantation of synthetic materials for giant and extensive hernias is accompanied by a significant number of wound complications caused by both the surgical technique itself and the reaction of surrounding tissues to a foreign body, requiring improvement of tactical and technical approaches when performing hernioplasty; it was clarified that scar-degenerative changes in the tissues of the aponeurosis in giant and extensive hernias are a predisposing factor to the occurrence of post-prosthetic hernias, especially when implanting the prosthesis in the “inlay” position and, accordingly, require increasing the efficiency of their fixation and engraftment, as well as reducing the risk of developing local complications; it was determined based on the data of an experimental study that the proposed method of alloplasty for large ventral hernias makes it possible to achieve adequate reconstruction of the anterior abdominal wall, reduce the incidence of infection in the wound, and also use a smaller size of prosthetic material; it was determined that the proposed method of tension-free repair of large hernias of the anterior abdominal wall with strengthening of the aponeurosis with a mesh implant allows maintaining physiology, reducing the number of complications, shortening treatment time and reducing the risk of hernia recurrence; It has been determined that the proposed method for preventing the development or progression of wound infection during alloplasty of ventral hernias can reduce the frequency of suppuration, shorten the treatment time and the likelihood of relapse; It has been proven that the use of the proposed tactical and technical aspects of prosthetic repair for postoperative ventral hernias can reduce the incidence of specific complications, reduce rehabilitation time and the risk of hernia recurrence. Reliability of the research results. The reliability of the results is justified by the use of objective criteria for assessing the condition of patients, modern methods of diagnosis and treatment, the correct application of methodological approaches and sets of statistical analysis, methods for solving the problems discussed in the dissertation are based on modern scientific and practical concepts and approaches to the diagnosis and surgical treatment of patients with giant postoperative hernias. Scientific and practical significance of the research results. The results obtained make a significant contribution to the expansion of irradiation of existing ideas about the structure and clinical features of complications of hernioplasty for giant and extensive ventral hernias by identifying the morphological features of the development of a purulent-inflammatory process against the background of the use of alloplastic material, studying predictors of the risk of developing immediate complications, mechanisms for enhancing reparative processes through the use of an improved method of fixing the prosthesis in together using the effect of photodynamic therapy through laser radiation, which made it possible to enhance the antibacterial effect and improve the wound healing process. The practical significance of the study is that, based on the results obtained, the tactical and technical aspects of prosthetic hernioplasty have been optimized, the features of methods of antiseptic exposure and laser stimulation of the wound surface after prosthetic repair have been revealed, enhancing preventive measures for the development of local infection, and the method of surgery for large anterior abdominal hernias has been improved walls, characterized by a combination of factors such as the formation of tension-free prosthetic plasty, preservation of local resorptive function to prevent the development of fluid accumulations, thereby reducing the risk of developing postoperative complications, reducing the frequency of unsatisfactory results, length of hospitalization and the likelihood of relapse. Implementation of research results. According to the results of a scientific study to optimize the tactical and technical aspects of surgical treatment of large and giant postoperative ventral hernias: the “method for plastic surgery of giant hernias of the anterior abdominal wall” has been improved (invention patent No. IAP 2022 0148 dated April 18, 2022). The proposed method of tension-free repair of large hernias of the anterior abdominal wall with strengthening of the aponeurosis with a mesh implant made it possible to reduce the number of complications, shorten the treatment time and reduce the risk of hernia recurrence; the “method for preventing the progression of infection during alloplasty of infected hernias” has been improved (certificate of the Ministry of Health No. 08-32071 dated October 17, 2022). The proposed method made it possible to reduce the frequency of wound purulent-inflammatory complications and shorten the period of rehabilitation of patients after allohernioplasty; methodological recommendations “Tactical and technical aspects of prosthetic repair for large and giant postoperative ventral hernias” have been developed (certificate of the Ministry of Health No. 08-32071 dated October 17, 2022) . The developed recommendations made it possible to optimize the tactical and technical aspects of allohernioplasty in patients with large and giant postoperative ventral hernias; The scientific results obtained were introduced into the practical activities of healthcare, in particular, in the departments of surgery of the Khorezm and Andijan regional multidisciplinary medical centers, the clinic of the Samarkand State Medical University (certificate of the Ministry of Health No. 08-32071 dated October 17, 2022). Improving the tactical and technical aspects of prosthetic repair for postoperative ventral hernias has made it possible to reduce the incidence of specific immediate complications from 40.9% to 15.6%, to reduce rehabilitation time from 8.6±2.7 to 7.1±1.5 days, and also reduce the likelihood of long-term complications from 11.7% to 3.1%.

The article is devoted to the study of the semantic analysis of the circumstances of the way of action, types of circumstances of the way of action, which determine the quality of the action, the degree of manifestation of the action or feature, indicating the state of the action, as well as the quality of the action and the way of performing the action. According to the semantic features of the circumstances of the course of action, it is worth noting that it is always an adverb in a sentence. For example, the circumstances of time, place, degree, or mode of action. In the Pashto language, a circumstance is divided according to semantics into the following ways of expression: circumstances that determine the quality of an action, the degree of manifestation of an action or a sign, circumstances that indicate the state of the action, circumstances of an action that indicate the quality of the performance of an action, as well as circumstances of an action that indicate a way to perform an action.
Creativity is a complex area that is explored and discussed from many different perspectives. This is one of the reasons why there is no universally accepted definition, and we must always know from what point of view we define creativity. A creative approach to language teaching is an approach that presents creativity as one of our many innate skills, a talent that every person and every language learner possesses. This approach is based on the idea that we can all be creative under certain conditions; that we all have many different forms and levels of creativity, and that it is the teacher's job to stimulate the creativity of students. This is why this article presents theories on this topic.

В современной абдоминальной хирургии одним из актуальных направлений для исследований продолжает оставаться совершенствование различных вариантов пластики послеоперационных грыж. В мире ежегодно выполняется более 2100000 операций по поводу вентральной грыжи и 42% из них -послеоперационные грыжи. В последние годы наблюдается явная тенденция к расширенному применению при гсрниопластикс различных вариантов биологических сеток. «Объединенный анализ семи исследований PCSTAR для послеоперационных грыж с использованием ретромускулярной сетки показал, что частота рецидивов грыжи составляет 5,7%». Применение стандартных оперативных вмешательств по типу аллопластики в положении onlay не решает проблему ранних послеоперационных осложнений: отхождение сером, миграция сетки, спаечпая болезнь, высокая частота рецидива грыж и др. В то же время пластика грыж местными тканями создает проблему повышения вну-трибрюшного давления, и поздним осложнениям в виде рецидивов грыж. «Рост послеоперационного внутрибрюшного давления приводит к полиорган-ной недостаточности, затем абдоминальному компартмент синдрому, и даже смерти». В настоящее время не существует консенсуса о хирургическом подходе при гигантских послеоперационных грыжах брюшной стенки, в связи с чем необходимость продолжения разработки новых технологий и совершенствования тактики не вызывает никаких сомнений.
В мировой практике в настоящее время наиболее актуальными продолжают оставаться исследования, направленные на изучение морфологических и функциональных аспектов рецидивных послеоперационных вентральных грыж, электронная микроскопия выявляет ультраструктурные деструктивные изменения клеток кожи, апоневроза и мышц, что свидетельствует о морфофункциональной недостаточности тканей брюшной стенки,обсуждаются вопросы клеточной инженерии новых инновационных материалов, проводятся шментальные исследования на животных с испытанием биотехнических свойств, текстуры и эластичности новых полимеров, проводятся исследования открытых доступов с разделением заднего компонента с выпуском поперечной мышцы живота и ретроградной сеткой, начаты роботизированные операции.
Современные аспекты развития отечественного здравоохранения включают множество мер, направленных на улучшение результатов лечения больных с послсопсрациоными вентральными грыжами и связанными с ними патологическими состояниями за счет внедрения современных принципов интенсивной терапии и хирургической тактики. В стратегию развития Нового Узбекистана на 2022-2026 годы по семи приоритетным направлениям включены задачи по повышению качества оказания населению квалифицированных медицинских услуг. Реализация данных задач, в том числе, путем оптимизации тактико-технических подходов к выбору метода герниопластики, а также разработка методов профилактики гнойно-воспалительных осложнений в области аллопластического матераиала, является одним из актуальных направлений абдоминальной хирургии и медицины в целом, ввиду высокой медико-социальной значимости данной патологии.
В результате исследований, проведённых в мире, по повышению эффективности аллопластики при послеоперационных вентральных грыжах и снижению риска осложнений в послеоперационном периоде получен ряд научных результатов, в том числе: определено, что пациенты, перенесшие реконструкцию брюшной стенки, имеют повышенный риск послеоперационной дыхательной недостаточности, понимание эпидемиологии этого осложнения может улучшить профилактику; доказано, что чем крупнее грыжа, тем выше риск ранних хирургических осложнений, в том числе таких как дыхательная декомпенсация, поскольку грыжи со временем часто увеличиваются в размерах, откладывание операции может привести к увеличению размеров грыжи и, следовательно, к большему риску осложнений; показано, что отношение объема грыжи к объему брюшной полости <20% является независимым фактором при закрытии без натяжения, что обосновывает интерес к предоперационной во-люметрии для адаптации тактики хирургической помощи; определено, что у пациентов, перенесших плановую лапароскопическую гсрниопластику, предикторами смертности являются более старший возраст и некоторые сопутствующие заболевания: застойная сердечная недостаточность, нарушения легочного кровообращения, коагулопатия, заболевания печени, метастатический рак, неврологические расстройства и паралич; установлено, что пожилой возраст, асцит, предоперационная почечная и легочная недостаточности являются независимыми предикторами 30-дневной смертности, при наличии этих факторов риска следует серьезно рассмотреть консервативное лечение; доказано, что универсальный калькулятор хирургического риска Американского колледжа хирургов (ACS) точно предсказывает тридцатидневные исходы, включающие серьезные осложнения: венозную тромбоэмболию, соматическую заболеваемость, инфекцию области хирургического вмешательства, незапланированную повторную операцию, смертность и продолжительность пребывания в стационаре.
В настоящий период в мире наиболее актуальными исследованиями в хирургии продолжают оставаться разработка новых методов герниопластики при больших и гигантских вентральных грыжах, каждый из которых имеет свои плюсы и минусы в зависимости от сложности выполнения, риска развития послеоперационных осложнений и рецидива, проводятся крупные рандомизированные клинические исследования, сравнивающие существующие методы традиционной герниопластики с лапароскопическим доступом и роботизированной хирургией, все более распространяющейся в последние 10 лет, проводится поиск новых синтетических и биологических материалов, разрабатываемых для производства и использования композитных сеток, обладающих необходимой прочностью и способностью предотвращать фатальные местные осложнения в условиях контаминированной среды. Однако, несмотря на технические достижения в этой области, ни один современный метод герниопластики и протезы не отвечают всем требованиям. Одна из ключевых проблем заключается в том, что существующие синтетические эндопротезы не имеют достаточной эластичности, устойчивости к инфицированию, высокой механической прочности и целостности в течение длительного времени. Дальнейшие исследования этих клинических аспектов несомненно улучшат современное представление о возможностях биосовместимых эндопротезов и позволят разработать оптимальный метод их расположения при аллогсрниопластикс.
Подход к пациентам с послеоперационными грыжами значительно изменился за последние 20 лет благодаря как достижениям в технологии создания сетки, так и хирургическим подходам. Ключевые факторы успешного исхода включают изменение факторов риска до операции, таких как отказ от курения и снижение веса, выбор сетки, соответствующей типу грыжи и запланированному расположению сетки, а также широкое перекрытие сетки за пределами грыжевого дефекта. У этих пациентов все чаще используются новые методы, такие как высвобождение трансабдоминальной мышцы и разделение компонентов с установкой ретроградной сетки и роботизированные подходы к грыже брюшной стенки. В последние годы наблюдается увеличение количества биологических сеток, доступных для герниопластики брюшной стенки. Биологические сетки обычно состоят из материалов, полученных от человека, свиньи или крупного рогатого скота. Обоснование использования биологических сеток заключается в том, что они могут действовать как каркас для прорастания естественных тканей. Кроме того, существуют рассасывающиеся синтетические сетки, которые обладают свойствами, аналогичными свойствам биологических сеток, но с теоретически меньшим риском, поскольку они не получены из животного или человеческого материала. Выбор сетки для вентральной грыжи зависит от множества факторов, которые включают в себя как свойства сетки, так и се расположение, например, внутрибрюшинно, предбрю-шинно или ретроректусно ее размещать. Кроме того, тип грыжевого дефекта является еще одним фактором риска, например, является ли рана чистой или грязной, и выполняется ли пластика мостовидным протезом или с опорой. Следует избегать легких или биологических сеток для перекрытия дефекта из-за повышенного количества рецидивов. Проведенный анализ литературы, касающейся теоретических аспектов и клинического опыта применения технологий совершенствования современных синтетических и биологических протезов, способных обеспечить более лучший пластический эффект, а также методов профилактики рецидивов вентральных грыж свидетельствует о том, что это является одним из приоритетных направлений в современной абдоминальной хирургии. Нерешенным вопросом остается выбор оптимального эндопротеза, обладающего высокой эффективностью и соответствующего международным стандартам, предъявляемым к таким свойствам как биологическая инертность и механическая прочность, а также метода расположения сетки по отношению к слоям брюшной стенки. Учитывая, что многие применяемые на сегодняшний день методы аллогерниопластики не лишены недостатков, актуальным направлением является разработка новых методов пластики при гигантских вентральных грыжах и способов профилактики послсопсрацитонных осложнений в условиях контаминированной раны, с обоснованием их эффективности в клинико-экспериментальном исследовании.
Atherosclerosis is a chronic lesion of the arteries caused by the growth of multiple dense nodular thickenings of the walls of the artery (plaques), narrowing its lumen and contributing to the formation of a blood clot - a thrombus, which can clog the vessel. Atherosclerosis develops as a result of complex structural changes that occur in the intima (inner layer) and in the media (muscle layer) of the arteries, and it is associated with the accumulation of lipids and mucopolysaccharides in the blood vessels, the growth of connective tissue and the deposition of calcium. Cardiovascular pathology, and this is ischemic heart and brain disease, occlusive diseases of peripheral arteries, is the most common cause of morbidity, mortality and disability in the population of industrialized countries. According to the statistics of the World Health Organization, in the structure of total mortality in Russia, cardiovascular diseases account for 57%. Most of these cases are associated with diseases caused by atherosclerosis [3]. The development of atherosclerotic lesions of the vascular wall is a complex multi-stage process. It has now been established that even before endothelial damage, blood components begin to interact with the endothelial surface. In particular, low-density lipoprotein cholesterol (LDL-C) and their active component apolipoproteins are able to penetrate into the subendothelial space and, being oxidized, affect endothelial cells. In this regard, the initial stage of atherosclerosis is characterized as a response to the retention of atherogenic particles [2]. The main risk factors that play a significant role in endothelial damage are smoking, arterial hypertension and hypercholesterolemia. It has been shown that with an increase in cholesterol levels of more than 8.5 mmol/l, the risk of fatal cardiovascular complications increases by 4 times, when combined with arterial hypertension by 9 times, with smoking, the presence of hypercholesterolemia and arterial hypertension by 16 times [1]. The problem of primary and secondary prevention of ischemic stroke is not only medical, but also of great social importance, since patients who have had it become disabled in more than 80% of cases and often need outside help. Statins are considered highly effective drugs with the greatest evidence in reducing the risk of cardiovascular events in patients with coronary artery disease.
Распространенность заболеваний желудочно-кишечного тракта (ЖКТ) у детей крайне велика и продолжает ежегодно увеличиваться. Диарея является основной причиной заболеваемости и смертности во всех возрастных группах и регионах мира. Тяжесть диареи у детей колеблется в широких пределах, точное оценить состояние обезвоживания имеет решающее значение для предотвращения смертности и заболеваемости. Исследования обнаружили, что ни один лабораторный тест или клиническим признаком не продемонстрировал адекватную чувствительность, специфичность и надежность для выявления тяжелой обезвоживания у детей.
The Convention on the Rights of the Child, which has been committed by almost all countries of the world, provides for the implementation of a wide range of legislative and administrative measures to ensure the interests of children, and, first of all, in the field of protecting their health. The health of children and adolescents is of exceptional importance in preserving the gene pool of the nation, the labor and defense potential of the country. In this regard, the reduction of infant and child mortality in the Republic of Uzbekistan is a national task. In children, due to anatomical and physiological features and rather significant differences in the nature of pathological processes, critical conditions occur much more often than in adults. Accidents (drowning, injuries, overheating, poisoning, bites, etc.), critical conditions and decompensation of chronic diseases in children and adolescents require timely specialized resuscitation care. The availability and quality of medical care at the resuscitation stage of treatment, regardless of the location of the patient, largely determines the outcome of the underlying disease. Therefore, the decisive role in reducing child mortality belongs to the resuscitation service.
