Одним из основных показателей, характеризующих контактирующие с кровью механические устройства (искусственные клапаны сердца, имплантируемые насосы и др.), является травма форменных элементов крови. Последние годы в клиническую практику для лечения детей с терминальными формами сердечной недостаточности все шире внедряются методы механической поддержки кровообращения. При разработке новых насосов одним из ключевых исследований in vitro является оценка гемолиза крови, вызываемой этими насосами. Поэтому на этапах разработки отечественного детского насоса (ДОН) параллельно со снятиями расходно-напорных характеристик нами были проведены исследования по оценке гемолиза. Предварительно был проведен анализ существующих методов и выбран наиболее оптимальный.</p></sec><sec><title>Цель</title><p>Цель. Разработать стандартизированную методику гемолизных испытаний насосов для крови применительно к отечественному детскому насосу ДОН, на основании которой провести исследования на этапах его разработки.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для проведения гемолизных испытаний создан гидродинамический стенд, состоящий из резервуара, помещенного в водяную баню, поддерживающую постоянную температуру рабочей жидкости (крови), гидродинамического сопротивления, соединительных трубок, порта для забора крови, системы измерения давления и расхода и исследуемого насоса. Методика испытаний заключается в оценке уровня свободного гемоглобина плазмы pHb, получаемого с помощью забора проб крови в процессе работы насоса в рабочем режиме (для детского насоса: расход 2,5 л/мин, перепад давления 80 мм рт. ст.). На основании полученных данных вычисляются стандартизированные индексы гемолиза NIH и МIH, рассчитываемые на основании анализа свободного гемоглобина в плазме проб крови, гематокрита, общего гемоглобина, расхода крови и времени работы насоса.</p></sec><sec><title>Результаты</title><p>Результаты. Разработана и реализована методика гемолизных испытаний, с помощью которой проведена оценка гемолиза, вызываемого ДОН, результаты которой позволили оптимизировать конструкцию насоса. Полученные значения гемолиза последней версии детского насоса ДОН-3 показали, что они соответствуют требованиям минимальной травмы крови и позволяют перейти к следующему этапу исследований детского насоса – экспериментам на животных.</p></sec><sec><title>Заключение</title><p>Заключение. Разработанные метод и средства оценки гемолиза крови позволяют дать объективную информацию об одном из наиболее важных показателей разрабатываемого имплантируемого детского осевого насоса и могут быть рекомендованы для проведения гемолизных исследований других конструкций насосов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. One of the main indicators characterizing mechanical circulatory support devices (artificial valve, implantable pumps, etc.) is trauma of blood cells. Therefore, while developing new pumps, one of the key studies in vitro is to evaluate blood hemolysis. For an objective hemolysis analysis of pump it is required to create a standardized methodology of hemolysis studies. The object of the study in this paper is implantable axial pump DON for two-step heart transplantation in children.</p><p>The aim of study is to develop a standardized methodology of hemolysis studies of blood pumps and to conduct research of pediatric axial pump DON.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. To conduct hemolysis research we created a mock circulatory system consisting of a reservoir placed in water bath maintaining a constant working fluid (blood) temperature, hydrodynamic resistance, connecting tubes, ports for blood sampling and pressure and flow measurement systems, and research pump. Test method is to estimate levels of free hemoglobin pHb obtained by blood samples during pump working in operating mode (for pediatric pump: blood flow 2.5 l/min, pressure difference 80 mmHg). Using the data obtained the standardized indices of hemolysis NIH and MIH are calculated based on pHb values, hematocrit, total hemoglobin, blood flow and working pump time.</p></sec><sec><title>Results</title><p>Results. We developed and realized a standardized methodology of hemolysis research by which we evaluated hemolysis of pediatric axial pump. The results of hemolysis tests allowed us to optimize the design of DON. Obtained values of hemolysis of the latest version of pediatric pump DON-3 have shown that they do conform to the requirements of minimum blood injury and it allows us to proceed to the next step of pediatric pump research – animal experiments.</p></sec><sec><title>Conclusion</title><p>Conclusion. Developed methods and evaluation tools of hemolysis allow us to provide objective information on one of the most important indicators of developing implantable pediatric axial pump and they could be recommended for hemolysis research of others pumps.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гидродинамический стенд</kwd><kwd>гемолизные испытания</kwd><kwd>детский осевой насос</kwd><kwd>терминальная сердечная недостаточность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrodynamic mock circulatory system</kwd><kwd>hemolysis research</kwd><kwd>pediatric axial pump</kwd><kwd>end-stage heart failure.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Throckmorton AL, Chopski SG.
