Quadratus lumborum block (QLB) has demonstrated these effects in abdominal surgery; however, its application in trauma and orthopedics remains understudied.</p> <p><bold>Aim:</bold> To evaluate the efficacy and safety of combining lateral and posterior approaches to QLB as a component of multimodal analgesia for postoperative pain management after THA.</p> <p><bold>Materials and methods:</bold> This single-center prospective randomized study included 153 patients aged 48–65 years undergoing THA. Participants were divided into two groups: Group 1 received preoperative QLB, while Group 2 served as the control. All patients underwent spinal anesthesia with intravenous sedation and received analgesia as part of multimodal pain management. Postoperative outcomes on the first day were assessed by measuring pain intensity using the visual analog scale (VAS) at rest and during mobilization, walking distance, opioid consumption, and the incidence of side effects from opioid use.</p> <p><bold>Results:</bold> VAS pain scores at 6, 12, and 24 hours postoperatively were significantly lower in the QLB group compared to the control group (<italic>p</italic> &lt;0.001). Walking distance also differed: Group 1 patients walked 10 [5; 20] m within the first 12 hours and 40 [30; 50] m within 24 hours, compared to 5 [0; 10] m and 30 [20; 40] m, respectively, in the control group (<italic>p</italic> &lt;0.017). In Group 1, 28 (50.67%) patients did not require opioids, and 37 (49.33%) needed them only once. In the control group, all patients required opioids, with 38 (50.67%) requesting repeated doses (<italic>p</italic> &lt;0.001).</p> <p><bold>Conclusion:</bold> This study demonstrated that QLB effectively reduces pain, opioid consumption, and associated complications while increasing mobility, confirming its efficacy and safety as a postoperative analgesic method for THA.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Использование регионарных методик для послеоперационного обезболивания при тотальном эндопротезировании тазобедренного сустава (ТЭТБС) позволяет минимизировать болевые ощущения и потребление опиоидов с сохранением двигательной активности пациентов. Блокада квадратной мышцы поясницы (БКМП) демонстрирует эти эффекты в абдоминальной хирургии, однако в травматологии и ортопедии её применение изучено недостаточно.</p> <p><bold>Цель.</bold> Оценить эффективность и безопасность комбинации латерального и заднего доступа БКМП в качестве компонента мультимодальной аналгезии в послеоперационном обезболивании после ТЭТБС.</p> <p><bold>Материалы и методы.</bold> Проведено одноцентровое проспективное рандомизированное исследование среди 153 пациентов в возрасте от 48 до 65 лет с показаниями к ТЭТБС, в итоговом анализе данных приняли участие 150 человек. Исследуемых разделили на 2 равные группы: в группе 1 перед операцией выполнили БКМП, группа 2 — сравнения; анестезиологическим обеспечением у всех пациентов была спинномозговая анестезия с внутривенной седацией, все пациенты получали обезболивание в рамках мультимодальной аналгезии. В первые сутки после операции оценивали интенсивность болевого синдрома по визуальной аналоговой шкале (ВАШ) в покое и при активизации пациента, пройденное ими расстояние, потребность в опиоидах и частоту возникновения нежелательных реакций после их введения.</p> <p><bold>Результаты.</bold> Интенсивность болевого синдрома по ВАШ в группе БКМП через 6, 12 и 24 ч после операции была ниже, чем в группе сравнения (<italic>р</italic> &lt;0,001), различалось и пройденное расстояние: в группе БКМП в первые 12 ч пациенты прошли 10 [5; 20] м, а в течение 24 ч — 40 [30; 50] м, в то время как пациенты группы сравнения преодолели 5 [0; 10] и 30 [20; 40] м соответственно (<italic>р</italic> &lt;0,017). От введения опиоидов отказались 50,67% (<italic>n</italic>=38) пациентов в группе БКМП, остальным 49,33% больным (<italic>n</italic>=37) эти препараты потребовались однократно; в группе сравнения опиоиды потребовались всем пациентам, причём 50,67% из них (<italic>n</italic>=38) — повторно (<italic>р</italic> &lt;0,001).</p> <p><bold>Заключение.</bold> БКМП снижает интенсивность болевого синдрома, потребление опиоидов и ассоциированных с ними осложнений, увеличивает пройденное пациентами расстояние, что свидетельствует о её эффективности и безопасности для послеоперационного обезболивания при ТЭТБС.</p></trans-abstract><kwd-group xml:lang="en"><kwd>total hip arthroplasty</kwd><kwd>quadratus lumborum block</kwd><kwd>fascial block</kwd><kwd>postoperative pain</kwd><kwd>regional anesthesia</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тотальное эндопротезирование тазобедренного сустава</kwd><kwd>блокада квадратной мышцы поясницы</kwd><kwd>фасциальный блок</kwd><kwd>послеоперационная боль</kwd><kwd>регионарная анестезия</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">Sereda AP, Kochish AA, Cherny AA, et al.
