At the end of the operation, a 22 cm multiperforated catheter was placed in the surgical wound under the aponeurosis. 3 hours after spinal anesthesia a loading dose — 8 ml of 0.2% ropivacaine was administered and followed by continuous infusion at rate 4 mL/h for 48 hours. Aside from CWI, all patients received systemic anesthesia: acetaminophen 4000 mg per os, ketorolac 90 mg IV and rescue opioid — tramadol up to 400 mg (as-needed) daily. Breast milk (colostrum) samples were collected after 24 and 48 hours after a loading dose and were analyzed by gas chromatography with a mass selective detector for total ropivacaine concentrations.</p> <p><bold>Results.</bold> The number of patients included in the study was 8. During the study neither cases of the onset of symptoms associated with systemic toxicity of ropivacaine, nor allergic and infectious complications, were observed. The mean +- SD Cmax total colostrum ropivacaine concentration was 0.005 ± 0.002 (0.002 – 0.007) μg / ml.</p> <p><bold>Conclusion. </bold>In this limited sample, increasing the concentration or/and infusion rate seems to be a safe (for both mother and newborn) alternative or adjunct to standard systemic analgesia after CS in order to provide proper postoperative pain control.</p></abstract><trans-abstract xml:lang="ru"><p>Ежегодно в России отмечается рост частоты кесарева сечения. Важным условием гладкого протекания послеоперационного периода является достаточный уровень анальгезии, позволяющий обеспечить раннюю активизацию пациентки, а также начало грудного вскармливания. Опиоиды в наибольшей степени проникают в грудное молоко, а основные системные препараты, обладающие опиоид-сберегающим эффектом, не зарегистрированы в РФ для применения с целью послеоперационной анальгезии при грудном вскармливании. Поэтому всё большую актуальность приобретает разработка методик продлённой регионарной анальгезии. На сегодня нет унифицированной схемы, определяющей оптимальную концентрацию и скорость введения местного анестетика.</p> <p><bold>Цель.</bold> Оценить безопасность грудного вскармливания при выбранной схеме длительной анальгезии послеоперационной раны (ДЛАР) раствором ропивакаина путём определения концентрации общего ропивакаина в грудном молоке (молозиве).</p> <p><bold>Материал и методы.</bold> Набор материала проводился на базе родильного дома МАУ «ГКБ № 40» г. Екатеринбурга в 2018–2020 гг. В исследование включено 8 пациенток после операции кесарева сечения в условиях спинальной анестезии раствором 5% бупивакаина — 2 мл. В послеоперационном периоде пациенткам с ДЛАР через 22-см мультиперфорированный катетер установлен под апоневроз мышц передней брюшной стенки. Режим введения анестетика: нагрузочная доза 0,2% ропивакаина – 8 мл, затем постоянная инфузия со скоростью 4 мл/ч в течение 48 ч. Забор грудного молока (молозива) производился через 24 и 48 ч после введения нагрузочной дозы. Количественное определение общей концентрации ропивакаина проводилось методом газовой хроматографии.</p> <p><bold>Результаты.</bold> Концентрация общего ропивакаина в грудном молоке составила Сm = 0,005 ± 0,002 (0,002–0,007) мкг/мл. Не было выявлено клинических признаков системной токсичности местных анестетиков ни у матерей, ни у новорождённых.</p> <p><bold>Вывод.</bold> Данное исследование позволяет говорить о безопасности выбранной схемы ДЛАР и подтверждает возможность её проведения без отсрочки начала/отмены грудного вскармливания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>wound analgesia</kwd><kwd>ropivacaine</kwd><kwd>local anesthetics</kwd><kwd>caesarean section</kwd><kwd>pain</kwd><kwd>postoperative pain relief</kwd><kwd>breastfeeding</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>анальгезия раны</kwd><kwd>ропивакаин</kwd><kwd>местные анестетики</kwd><kwd>кесарево сечение</kwd><kwd>боль</kwd><kwd>послеоперационное обезболивание</kwd><kwd>грудное вскармливание</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">Matsota PK, Markantonis SL, Fousteri MZ et al.
