Оценить влияние проводниковых блокад нервов на обезболивание и двигательную функцию нижней конечности после тотального эндопротезирования коленного сустава (ТЭКС) .</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены 63 пациента, которым выполнено ТЭКС. Группу 1 составили 29 пациентов, которым после операции провели блокады периферических нервов нижней конечности (n. tibialis, n. saphenus, n. vastus medialis, n. obturatorius и передних кожных ветвей бедренного нерва). Группу 2 составили 34 пациента без проводниковых блокад. Оценку болевого синдрома проводили с помощью визуальной аналоговой шкалы (ВАШ) через 2, 3, 4, 5, 6, 8, 12, 24, 36 и 48 ч после операции. Для оценки силы квадрицепса бедра использовали шкалу Medical Research Council Muscle Scale (MRC) через 3, 6, 12, 24 и 36 ч после эндопротезирования.</p></sec><sec><title>Результаты</title><p>Результаты. На всех послеоперационных этапах исследования значимо меньшие оценки боли были выявлены в группе пациентов, которым после тотального эндопротезирования коленного сустава выполнили проводниковые блокады нервов, р &lt; 0,05. Достоверные различия в силе квадрицепса между группами выявлены через 3 ч после операции: в группе 1 — 3 [2; 4] балла, а в группе 2 — 4 [3; 5] балла (р &lt; 0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Блокады периферических нервов нижней конечности эффективно снижают боль после эндопротезирования коленного сустава и в 20,7 % случаев позволяют приступить к ранней активизации пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To assess the effect of nerve blocks on pain relief and motor function of the lower limb after total knee arthroplasty.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 63 patients who underwent total knee arthroplasty. Group 1 consisted of 29 patients who underwent blockades of the peripheral nerves of the lower limb (n.tibialis, n.saphenus, n. to vastus medialis, n.obturatorius and anterior cutaneous branches of the femoral nerve) after surgery. Group 2 consisted of 34 patients without blocks. Pain syndrome was assessed using a visual analog scale (VAS) in 2, 3, 4, 5, 6, 8, 12, 24, 36 and 48 hours after surgery. The Medical Research Council Muscle Scale (MRC) was used to assess the strength of the quadriceps of femor in 3, 6, 12, 24 and 36 hours after surgery.</p></sec><sec><title>Results</title><p>Results. Throughout all postoperative stages of the study, significantly lower pain scores were found in the group of patients who underwent nerve blockade after total knee arthroplasty, p&lt;0.05. Significant differences in quadriceps strength between the groups were found only in 3 hours after surgery: in the group 1 – 3 [2; 4] points, and in the group 2 – 4 [3; 5] points (p&lt;0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Nerve blocks of the lower limb effectively reduce pain after knee arthroplasty, and in 20.7% of cases allow early mobilization of patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>артропластика коленного сустава</kwd><kwd>регионарная анестезия</kwd><kwd>послеоперационная боль</kwd><kwd>сила квадрицепса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>knee arthroplasty</kwd><kwd>regional anesthesia</kwd><kwd>postoperative pain</kwd><kwd>quadriceps strength</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">Kurtz SM, Lau E, Ong K, Zhao K, Kelly M, Bozic KJ.
