Peripheral nerve blocks have emerged as a viable alternative to neuraxial techniques. However, the optimal approach to analgesia for pediatric hip surgery remains unclear. Fascia iliaca compartment block (FICB) is one of the most studied and safest peripheral regional anesthesia techniques in children. The pericapsular nerve group (PENG) block has demonstrated safety and opioid-sparing efficacy in adults; however, evidence for its use in pediatric patients is currently limited to case series.</p> <p><bold>AIM: </bold>This study aimed to compare the perioperative analgesic efficacy of the pericapsular nerve group block and fascia iliaca compartment block in pediatric hip surgery.</p> <p><bold>METHODS:</bold> This single-center, prospective, randomized study included 86 children undergoing reconstructive hip surgery. Patients were allocated into two equal groups: the PENG group and the FICB group. All patients received combined endotracheal anesthesia with sevoflurane. Regional anesthesia was performed under ultrasound guidance. Postoperative outcomes included total opioid analgesic requirements, time to first opioid analgesia, pain intensity assessed using the revised Face, Legs, Activity, Cry, Consolability scale and the Numerical Rating Scale, and the Analgesia Nociception Index (ANI) measured during the first 24 hours after regional anesthesia. Intraoperative parameters included mean arterial pressure, heart rate, ANI, and fentanyl requirements.</p> <p><bold>RESULTS:</bold> The total dose of trimeperidine did not differ significantly between groups: 0.12 (0–0.48) mg/kg in the PENG group versus 0 (0–0.41) mg/kg in the FICB group.</p> <p>Additional analgesia was required in 24 patients (56%) in the PENG group and 17 patients (40%) in the FICB group. Time to first opioid requirement did not differ significantly between groups (<italic>p</italic> = 0.1) and was 11 (12.0–24.0) hours in the PENG group and 24 (5.0–24.0) hours in the FICB group.</p> <p>No differences in pain intensity were observed between groups in children according to both pain scales. Analysis of ANI values revealed a significant difference between groups at 24 hours (<italic>p</italic> = 0.02). The median ANI in the PENG group at 24 hours was lower than in the FICB group (69 vs. 81). An increase in blood pressure and heart rate at the time of skin incision was observed in the PENG group, whereas no such changes were noted in the FICB group. No adverse events or complications were reported with either technique.</p> <p><bold>CONCLUSION: </bold>The pericapsular nerve group block may be used in pediatric hip surgery as a safe and effective component of multimodal analgesia. Opioid requirements, time to first opioid analgesia, and intraoperative opioid use were comparable to those observed with fascia iliaca compartment block.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Регионарная анестезия является неотъемлемой частью концепции быстрого восстановления пациентов. Периферические регионарные блокады зарекомендовали себя как достойная альтернатива нейроаксиальным методам. Тем не менее остаётся открытым вопрос о выборе оптимальной методики при обезболивании операций на тазобедренном суставе у детей. Одним из наиболее изученных и безопасных методов периферической регионарной анестезии у детей является подвздошно-фасциальная блокада (FICB). Кроме того, метод блокады перикапсулярной группы нервов (PENG-блок) зарекомендовал себя как безопасная и эффективная опиоидсберегающая методика у взрослых пациентов, однако в педиатрии на настоящий момент данные о применении PENG-блока ограничены лишь сериями случаев.</p> <p><bold>Цель. </bold>Сравнение периоперационной анальгетической эффективности PENG-блока и FICB при оперативном вмешательстве на тазобедренном суставе у детей.</p> <p><bold>Методы.</bold> Проведено одноцентровое проспективное рандомизированное исследование. Включено 86 детей, которым выполнялись реконструктивные операции на тазобедренном суставе. Пациенты разделены на 2 равные группы: группа PENG и группа FICB. Всем пациентам проводили сочетанную эндотрахеальную анестезию с использованием севофлурана. Регионарную анестезию выполняли с использованием ультразвуковой навигации. В послеоперационном периоде оценивали суммарную потребность в наркотических анальгетиках, время до первой необходимости в аналгезии опиоидами, уровень болевого синдрома с использованием шкал r-FLACC и NRS, измеряли индекс аналгезии-ноцицепции (ANI) в течение первых 24 часов после выполнения регионарной анестезии. Интраоперационно оценивали показатели среднего артериального давления, частоты сердечных сокращений, ANI, а также уровень потребности в обезболивании фентанилом.</p> <p><bold>Результаты.</bold> Суммарная доза тримеперидина значимо не отличалась между группами: в группе PENG — 0,12 (0–0,48) мг/кг, в группе FICB — 0 (0–0,41) мг/кг.</p> <p>Дополнительное обезболивание потребовалось 24 пациентам (56%) из группы PENG и 17 пациентам (40%) из группы FICB. Время до первой потребности в опиоидах значимо не отличалось (<italic>p=</italic>0,1) при межгрупповом сравнении и составило 11 (12,0–24,0) ч в группе PENG и 24 (5,0–24,0) ч в группе FICB.</p> <p>Не было выявлено разницы в уровне болевого синдрома у детей при оценке по обеим шкалам боли. При анализе показателей ANI выявлена статистически значимая (<italic>p=</italic>0,02) разница между группами в точке наблюдения через 24 часа. Медиана ANI в группе PENG через 24 часа была ниже, чем в группе FICB, и составила 69 и 81 соответственно. Отмечено повышение показателей артериального давления и частоты сердечных сокращений на этапе кожного разреза в группе PENG, тогда как у пациентов в группе FICB таких изменений не наблюдалось. Нежелательных явлений и осложнений при выполнении обоих методов отмечено не было.</p> <p><bold>Заключение.</bold> PENG-блок может использоваться при операциях на тазобедренном суставе у детей как безопасный и эффективный компонент мультимодальной аналгезии. Уровень потребности в опиоидах, время до потребности в опиоидной аналгезии, а также интраоперационная потребность в наркотических анальгетиках сопоставимы с применением FICB.</p></trans-abstract><kwd-group xml:lang="en"><kwd>local anesthesia</kwd><kwd>epidural anesthesia</kwd><kwd>nerve block</kwd><kwd>postoperative pain</kwd><kwd>hip dislocation</kwd><kwd>pediatric regional anesthesia</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>местная анестезия</kwd><kwd>эпидуральная анестезия</kwd><kwd>блокада нервов</kwd><kwd>послеоперационная боль</kwd><kwd>вывих бедра</kwd><kwd>регионарная анестезия у детей</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Wick EC, Grant MC, Wu CL.
