Разработка оптимальных методов интраоперационной защиты, таких как локальная фармакохолодовая перфузия, остаётся актуальной задачей.</p><p>Целью данного исследования на кроликах стала сравнительная гистологическая оценка нефропротекторной эффективности двух режимов перфузии (непрерывной капельной и фракционной) охлаждёнными растворами на основе Рингера и «Кустодиола» при 60-минутной ишемии.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование выполнено на 22 кроликах, разделённых на 6 групп: интактный контроль, модель ишемии без защиты и 4 группы с разными методами перфузии (непрерывная/фракционная, раствор «Рингер-ФГ»/«Кустодиол»). После 60 минут ишемии почечной артерии с параллельной перфузией и 48 часов реперфузии проводили гистологическое и морфометрическое исследование почечной ткани.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Ишемия без защиты вызывала выраженные повреждения: полнокровие, атрофию клубочков, дистрофию и некроз канальцев. Все протоколы перфузии значимо снижали тяжесть повреждений. Ключевым фактором эффективности оказался режим введения: непрерывная капельная перфузия была достоверно эффективнее фракционной (p ≤ 0,05). Наиболее сбалансированный защитный эффект на оба отдела нефрона продемонстрировала непрерывная капельная перфузия охлаждённым раствором «Рингер-ФГ» под низким давлением (35–45 мм рт. ст.).</p></sec><sec><title>Заключение</title><p>Заключение. Непрерывное капельное введение растворов для фармакохолодовой перфузии превосходит по эффективности фракционный режим. Оптимальным методом в условиях эксперимента является непрерывная капельная перфузия охлаждённым раствором «Рингер-ФГ» под низким давлением, обеспечивающая наилучшую сохранность как клубочкового, так и канальцевого аппарата почки.</p></sec></abstract><trans-abstract xml:lang="en"><p>Acute ischemic kidney injury is a serious complication in aortic and renal artery surgery. The development of optimal methods of intraoperative protection, such as local pharmaco-cold perfusion, remains a pressing issue.</p><p>The aim of this study in rabbits was to comparatively evaluate the histological efficacy of two perfusion regimens (continuous drip and fractional) with cooled Ringer’s and Custodiol-based solutions during 60-minute ischemia.</p><sec><title>Materials and Methods</title><p>Materials and Methods. The study was performed on 22 rabbits divided into 6 groups: intact control, an ischemia model without protection, and 4 groups with different perfusion methods (continuous/fractional, Ringer’s-FG/Custodiol solution). After 60 minutes of renal artery ischemia with parallel perfusion and 48 hours of reperfusion, histological and morphometric examination of the renal tissue was performed.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Ischemia without protection caused significant damage: glomerular congestion, atrophy, and tubular degeneration and necrosis. All perfusion protocols significantly reduced the severity of damage. The key factor in efficacy was the administration mode: continuous drip perfusion was significantly more effective than fractional perfusion (p ≤ 0.05). Continuous drip perfusion with cooled Ringer’s solution at low pressure (35–45 mmHg) demonstrated the most balanced protective effect on both nephron compartments.</p></sec><sec><title>Conclusion</title><p>Conclusion. Continuous drip perfusion of solutions for pharmaco-cold perfusion is superior to fractional perfusion. The optimal method for experimental conditions is continuous drip perfusion with chilled Ringer’s-FG solution under low pressure, ensuring the best preservation of both the glomerular and tubular apparatus of the kidney.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острое ишемическое повреждение почек</kwd><kwd>интраоперационная защита</kwd><kwd>фармакохолодовая перфузия</kwd><kwd>гистология</kwd><kwd>эксперимент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute ischemic kidney injury</kwd><kwd>intraoperative protection</kwd><kwd>pharmaco-cold perfusion</kwd><kwd>histology</kwd><kwd>experiment</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">Identification and kinetics of leukocytes after severe ischaemia/reperfusion renal injury / D.K.
