It often leads to death. At present method of coagulationby "nonequilibrium plasma" is developed.Aim: study the effect of "non-equilibrium plasma" on the hemostatic system and morphofunctional state of the spleen.Materials and Methods: The experiment was carried out on 45 male rabbits weighing 3000 - 3200 g. 1st group (control; n=5) -intact animals without surgery; 2nd group (experimental, n=40) - animals after atypical resection of the spleen and hemostasisby "nonequilibrium plasma". The volume of blood loss, FBC, histological data (specific volume of red and white pulp, vessels,connective tissue, the density of the cellular infiltrate), splenogram analysis (microscopy of spleen impression smears) data wereassessed at defined periods (60 min, 3rd, 5th, 7th, 14th, 30th, 90th, 180th days) after surgery. Them were compared with data of thecontrol group.Results and discussions: The volume of blood loss during the resection of the spleen with hemostasis by "nonequilibrium plasma"was 16,6 [15,98;17,22] ml. Increase of neutrophil to 38 [24; 39] (control group 17 [13, 18], p=0,009), monocytes to 15 [14, 18](control group 8 [6, 11], p=0,036) is revealed in the FBC in the early period after hemostasis with nonequilibrium plasma. It isreduced to the norm on 30 day. Histological examination revealed leukocyte infiltration, edema, microvascular stasis, dilatation ofvessels in the early period. At long-term period structure of the organ is normalized. Splenogramm analysis revealed a statistically </p><p>significant (p = 0,023) decrease in the relative number of small lymphocytes by 28% in animals after hemostasis with nonequilibriumplasma as compared to control (23.3 [17.9; 26.7] versus 30.8 [29.25; 34.3] in the control group).Conclusion: treatment of bleeding surface by plasma flow for 1.5-2 min is required order to achieve effective hemostasis duringsurgery of spleen injuries in the experiment. After hemostasis by "nonequilibrium plasma" there is minimal damage of the spleenparenchyma, which manifests itself as "activation reaction" in the first minutes after exposure. At long-term period parenchyma ofthe spleen completely regenerates with the formation of cicatrical tissue that does not affect the functioning of organ.Key words: haemostasis of spleen, nonequilibrium plasma, spleen trauma, morphofunctional changes.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность: при повреждении селезенки развивается обильное кровотечение, приводящее к летальному исходу. В на-стоящее время разрабатывается метод гемостаза «неравновесной плазмой».Цель: изучить влияние «неравновесной плазмы» на систему гемостаза и морфофункциональное состояние селезенки.Материалы и методы: Эксперимент проводили на кроликах-самцах. 1-я группа (контроль; n=5) – интактные животныебез оперативного вмешательства; 2-я группа (экспериментальная, n=40) – животные после атипичной резекции селезен-ки и гемостаза «неравновесной плазмой». В заданные временные промежутки (60 мин, 3-е, 5-е, 7-е, 14-е, 30-е, 90-е, 180-есут) после оперативного вмешательства оценивались объём кровопотери, ОАК, гистологические данные (удельный объемкрасной и белой пульпы, сосудов, соединительной ткани, плотность клеточного инфильтрата), проводился анализ сплено-грамм (микроскопия мазков-отпечатков срезов селезенки).Результаты и их обсуждение: Объём кровопотери при резекции селезенки с гемостазом «неравновесной плазмой» соста-вил 16,6 [15,98;17,22] мл. В ОАК на ранних сроках после гемостаза неравновесной плазмой выявляется увеличение нейтро-филов до 38 [24; 39] (группа контроля 17[13;18], p=0,009) и моноцитов до 15 [14;18] (группа контроля 8[6;11], p=0,036),которое снижается до нормы к 30 сут. При гистологическом исследовании на ранние сроки выявляется лейкоцитарнаяинфильтрация, явления отёка, стаз сосудов микроциркуляторного русла, расширение сосудов. На поздние сроки структу-ра органа нормализуется. Анализ спленограмм выявил статистически значимое (p=0,023) снижение лишь относительногоколичества малых лимфоцитов на 28% у животных после гемостаза неравновесной плазмой по сравнению с контролем(23,3 [17,9; 26,7] против 30,8 [29,25; 34,3] в контрольной группе).Выводы: эффективный гемостаз селезенки в эксперименте наступает после обработки плазменным потоком кровото-чащей поверхности в течение 1,5-2 мин. После гемостаза «неравновесной плазмой» отмечается повреждение паренхимыселезенки, проявляющееся «реакцией активации». В отдалённые сроки паренхима селезенки регенерирует с образованиемсоединительнотканного рубца, функция органа не страдает.Ключевые слова: гемостаз селезенки, неравновесная плазма, повреждения селезёнки, морфофункциональные изменения.</p></trans-abstract><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
