Three groups were distinguished, differing in the chosen method of regional anesthesia. Group 1 included patients with a combination of afferent canal block and IPACK block, group 2 included patients with femoral nerve block, and group 3 included patients with femoral nerve block and IPACK block. Pain at rest and during movement, the need for opioid analgesics in the postoperative period, and the possibility of early activation of patients after knee arthroplasty were assessed on a visual analog scale. The incidence of side effects associated with regional anesthesia was also noted.</p> <p><italic><bold>RESULTS</bold></italic>: The study showed that the combination of adductor canal blockade and IPACK blockade showed the best effectiveness of pain syndrome control. Patients were less likely to need narcotic analgesics, there was no development of motor block and, as a result, patients were more satisfied with anesthesia. The combination of blockades made it possible to accelerate the rehabilitation of patients in the postoperative period, due to a decrease in pain and the absence of a motor block.</p> <p><italic><bold>CONCLUSIONS</bold></italic>: The use of IPACK blockade in combination with adductor canal blockade provides effective analgesia and reduces the use of analgesics, as well as increases the patient's rehabilitation potential.</p></abstract><trans-abstract xml:lang="ru"><p><italic><bold>Цель исследования</bold></italic>: изучить эффективность и безопасность применения комбинации IPACK-блока и блока приводящего канала в сравнении с блокадой бедренного нерва после операций на коленном суставе.</p> <p><italic><bold>Материалы и методы</bold></italic>. Двойное слепое проспективное рандомизированное контролируемое исследование с участием 101 пациента. Выделено 3 группы, различающиеся выбранным способом регионарной анестезии. В группу 1 вошли пациенты с комбинацией блокады приводящего канала и IPACK-блокадой, в группу 2 – пациенты с блокадой бедренного нерва, в группу 3 – пациенты с блокадой бедренного нерва и IPACK-блокадой. Оценивались болевой синдром в покое и при движении по визуально-аналоговой шкале, потребность пациентов в опиоидных анальгетиках в послеоперационном периоде и возможность ранней активизации больных после эндопротезирования коленного сустава. Также отмечалась частота возникновения побочных эффектов, связанных с регионарной анестезией.</p> <p><italic><bold>Результаты</bold></italic>. Исследование показало, что наилучшую эффективность контроля болевого синдрома показала комбинация блокады приводящего канала и IPACK-блокады. Пациенты реже нуждались в назначении наркотических анальгетиков, отсутствовало развитие моторного блока и, как следствие, пациенты были более удовлетворены анестезией. Комбинация блокад позволила ускорить реабилитацию пациентов в послеоперационном периоде, вследствие снижения болевого синдрома и отсутствия моторного блока.</p> <p><italic><bold>Выводы</bold></italic>. Использование iPACK-блокады в комбинации с блокадой приводящего канала позволяет обеспечить эффективную анальгезию и сократить приём анальгетиков, а также повысить реабилитационный потенциал пациента.</p></trans-abstract><kwd-group xml:lang="en"><kwd>iPACK-block</kwd><kwd>adductor canal block</kwd><kwd>total knee replacement</kwd><kwd>enhanced recovery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>iPACK-блок</kwd><kwd>блокада приводящего канала</kwd><kwd>тотальное эндопротезирование коленного сустава</kwd><kwd>ранняя реабилитация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Ovechkin AM, Politov ME, Panov N.V.
