However, because of the variety of regional analgesia techniques, the superiority of the quadratus lumborum block over the transversus abdominis plane block remains a subject of debate.</p> <p><bold>AIM:</bold> This study aimed to compare the analgesic effectiveness of the transversus abdominis plane block and the quadratus lumborum block in the early postoperative period after cesarean section.</p> <p><bold>METHODS:</bold> This prospective, randomized study was based on the analysis of analgesic effectiveness in 78 women who underwent cesarean section and received analgesia using two methods: transversus abdominis plane block and quadratus lumborum block. Patients were randomized into two groups: group 1 consisted of 39 patients who received the transversus abdominis plane block as postoperative analgesia; group 2 included 39 patients who received the quadratus lumborum block. The quality of analgesia, its analgesia, overall need for additional analgesia, pain intensity before block placement, and the impact of the block on postoperative analgesia quality were assessed. Pain was evaluated using the visual analog scale at rest at the following time points: before analgesia, at 6 hours, at 12 hours, and 12 hours after transfer to the postpartum ward. The need for additional analgesia was also recorded.</p> <p><bold>RESULTS:</bold> Pain intensity before analgesia varied considerably between groups; however, intergroup differences in frequency distributions of visual analog scale scores were not significant (<italic>p</italic> = 0.061). Pain intensity at 6 and 12 hours after the block did not differ significantly between the groups. No statistically or clinically significant difference in the frequency of additional analgesia was observed (<italic>p</italic> = 0.062). These data indicate comparable analgesic effectiveness of both methods. The analysis of analgesia quality after cesarean section prior to block administration revealed a significant difference in analgesia satisfaction curves between the studied groups. Specifically, in the transversus abdominis plane block group, a nerve block was required substantially earlier after surgery compared with the quadratus lumborum block group (<italic>p</italic> = 0.0012).</p> <p><bold>CONCLUSIONS:</bold> The use of interfascial blocks (transversus abdominis plane block and quadratus lumborum block) provided a comparable analgesic effect in the early postoperative period after cesarean section.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Смешанный характер боли (висцеральный и соматический компоненты) после операции кесарево сечение (КС) и использование межфасциальных блокад значительно повлияло на эффективность послеоперационного обезболивания пациенток. Однако в связи с многообразием методов регионарной аналгезии вопрос о преимуществе блокады квадратной мышцы поясницы над блокадой поперечного пространства живота остаётся открытым.</p> <p><bold>Цель</bold> — сравнение анальгетической эффективности в раннем послеоперационном периоде операции кесарево сечение блокад поперечного пространства живота и квадратной мышцы поясницы.</p> <p><bold>Методы</bold>. В основу проспективного рандомизированного исследования положены результаты анализа эффективности обезболивания 78 родильниц, перенёсших операцию кесарево сечение, которым проводилась аналгезия двумя методами: блокада поперечного пространства живота и блокада квадратной мышцы поясницы. Пациентки были рандомизированы на 2 группы: Группу 1, в которой в качестве метода послеоперационного обезболивания использовалась поперечная блокада живота, составили 39 пациенток; Группу 2, с использованием блокады квадратной мышцы поясницы, — также 39 пациенток. Оценивались качество аналгезии, продолжительность обезболивания, общая потребность в дополнительной аналгезии, интенсивность болевого синдрома до выполнения блокады и её влияние на качество послеоперационного обезболивания. Для оценки использовались визуальная аналоговая шкала у пациенток в покое с интервалами: до аналгезии, через 6 часов, через 12 часов и спустя 12 часов после перевода в послеродовое отделение. Помимо этого, регистрировалась потребность в дополнительной аналгезии.</p> <p><bold>Результаты.</bold> Выраженность болевого синдрома до обезболивания значительно варьировала между группами, однако межгрупповые различия распределений частот по баллам визуальной аналоговой шкале не достигли статистической значимости (<italic>p</italic> = 0,061). Интенсивность болевого синдрома через 6 часов и через 12 часов после выполнения блокады существенно не отличалось в исследуемых группах. Не было получено статистически и клинически значимого различия частоты дополнительного обезболивания (<italic>p</italic> = 0,062). Эти данные свидетельствуют об одинаковой эффективности обезболивания обоих методов. В результате анализа качества обезболивания у пациенток после операции кесарево сечение до выполнения блокады отмечалось статистически значимое различие кривых удовлетворённости обезболиванием между исследуемыми группами. Так, в группе блокады поперечного пространства живота проведение блока требовалось значительно раньше после операции, чем в группе блокады квадратной мышцы поясницы (<italic>p</italic> = 0,0012).</p> <p><bold>Заключение.</bold> Применение межфасциальных блокад (поперечного пространства живота и квадратной мышцы поясницы) обеспечивало сопоставимый анальгетический эффект в ранний послеоперационный период операции кесарева сечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cesarean section</kwd><kwd>pain</kwd><kwd>transversus abdominis plane block</kwd><kwd>analgesia</kwd><kwd>postoperative analgesia</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кесарево сечение</kwd><kwd>боль</kwd><kwd>блокада поперечного пространства живота</kwd><kwd>обезболивание</kwd><kwd>послеоперационное обезболивание</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Upryamova EY, Shifman EM, Degtyarev PA, Snezhko VD, Maksimkina TA.
