Optimization of anesthesia management without opioids remains an important clinical challenge.</p> <p><bold>CASE DESCRIPTION</bold><bold>: </bold>A 35-year-old female patient (height 164 cm, weight 180 kg, body mass index 66.9 kg/m<sup>2</sup>) underwent robot-assisted hysterectomy for recurrent endometrial hyperplasia under combined anesthesia (general anesthesia with epidural analgesia).</p> <p>The mean qCON (consciousness index) during surgery was 50.2. The analgesic component of anesthesia was achieved through epidural administration of 0.1% ropivacaine hydrochloride solution, 10 mL every 30 minutes, at an infusion rate of 250 mL/hour during bolus delivery. The mean qNOX (nociception index) was 29.8. The mean total duration of qNOX peaks was 98.2 seconds over the 2 hours 35 minutes of surgery. Intraoperative hemodynamics were stable: blood pressure ranged from 120/70 to 140/80 mm Hg, heart rate 70–80 bpm, and SpO<sub>2</sub> 98–100%. Muscle relaxation was not maintained by additional administration of rocuronium bromide due to adequate relaxation of the abdominal wall and absence of inspiratory triggering from the patient. The TOF neuromuscular transmission ratio ranged from 40% to 50%, and electromyography (EMG) values ranged from 10 to 25, indicating adequate relaxation of the anterior abdominal wall muscles. The postoperative period was uneventful. The patient was discharged on postoperative day 6 in satisfactory condition with no active complaints.</p> <p><bold>CONCLUSION</bold><bold>:</bold> In this clinical case, the chosen anesthesia management tactic provided effective analgesia and enabled early mobilization of the patient.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Пациенты с морбидным ожирением при общей анестезии в лапароскопической хирургии отличаются повышенным риском осложнений: транзиторная гипоксемия, гемодинамическая нестабильность, медленное пробуждение, повышенная чувствительность к опиоидам, послеоперационные лёгочные осложнения, послеоперационная тошнота и рвота. Оптимизация анестезиологического обеспечения без использования опиоидов является актуальной задачей.</p> <p><bold>Описание клинического случая.</bold> Пациентке 35 лет (рост — 164 см, масса тела — 180 кг, индекс массы тела — 66,9 кг/м<sup>2</sup>) выполнена робот-ассистированная гистерэктомия по поводу рецидивирующей гиперплазии эндометрия с применением сочетанной анестезии (общая анестезия в сочетании с эпидуральной аналгезией).</p> <p>Средний qCON (индекс сознания) за операцию составил 50,2. Анальгетический компонент анестезии достигался эпидуральным введением 0,1% раствора ропивакаина гидрохлорида — 10 мл каждые 30 мин, со скоростью введения во время болюса 250 мл/ч. Средний qNOX (индекс ноцицепции) соответствовал 29,8. Среднее общее время пиков qNOX составило 98,2 с за 2 часа 35 минут операции. Интраоперационная гемодинамика была маловариабельной: артериальное давление 120/70–140/80 мм рт. ст., частота сердечных сокращений 70–80 в минуту, SpO<sub>2</sub> 98–100%. Миорелаксацию дополнительным введением рокурония бромида не поддерживали ввиду достаточности релаксации брюшной стенки и отсутствия триггирования вдоха со стороны пациентки. Показатель нервно-мышечной проводимости по TOF находился в диапазоне от 40 до 50%, а показатель электромиографии (EMG) — в диапазоне от 10 до 25, что свидетельствовало о достаточной релаксации мышц передней брюшной стенки. Послеоперационный период протекал без осложнений. Пациентка была выписана на шестые сутки после оперативного вмешательства в удовлетворительном состоянии без активных жалоб.</p> <p><bold>Заключение.</bold> В данном клиническом случае выбранная тактика анестезиологического обеспечения позволила достичь хорошей аналгезии и провести раннюю активизацию пациентки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>opioid-free anesthesia</kwd><kwd>morbid obesity</kwd><kwd>robot-assisted surgery</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>безопиоидная анестезия</kwd><kwd>морбидное ожирение</kwd><kwd>робот-ассистированная хирургия</kwd><kwd>клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Alferova VI, Mustafina SV.
