All patients underwent postoperative epidural analgesia.</p> <p>A method for assessing the degree of external dislocation of an epidural catheter and an algorithm of actions when detecting a dislocation of an epidural catheter has been developed. The degree of dislocation of the epidural catheter was assessed when changing the fixing aseptic sticker and additional measures were taken to enhance the fixation of the epidural catheter when a pronounced dislocation was detected.</p> <p><italic><bold>RESULTS</bold></italic>: The use of the method for assessing the degree of external dislocation of the epidural catheter and the implementation of the algorithm of actions upon the detection of the epidural catheter dislocation made the conduction of high-quality postoperative anesthesia in 61 patients possible. In 10 patients, when a pronounced dislocation was detected and the threat of the epidural catheter was loss (dislocation of 4–5 degrees, 15–30 mm), special fixation devices “Epi-Fix” were used for additional fixation, which made the continuation of the epidural analgesia possible.</p> <p>In the first case (1.61%), wherein epidural analgesia had to be discontinued after 48 h, the 6th degree of dislocation of the epidural catheter (33 mm) was established and the catheter was removed. Postoperative pain relief was continued with the introduction of non-steroidal anti-inflammatory drugs.</p> <p><italic><bold>CONCLUSIONS</bold></italic>: Using the method for assessing the degree of external dislocation of an epidural catheter in the daily practice of an anesthesiologist-resuscitator assessed the risk of deterioration and termination of epidural anesthesia possible, thus prevention measures were performed.</p></abstract><trans-abstract xml:lang="ru"><p><italic><bold>Цель</bold></italic>. Показать практическую значимость предлагаемого способа оценки степени наружной дислокации эпидурального катетера в ежедневной работе врача анестезиолога-реаниматолога, с помощью которого врач может оценить риск ухудшения качества проводимого обезболивания и, используя разработанный алгоритм, принять меры для недопущения выпадения эпидурального катетера и прекращения эпидуральной анальгезии.</p> <p><italic><bold>Материалы и методы</bold></italic>. В целях проводимого исследования было отобрано 62 пациента, которым была проведена двухуровневая комбинированная спинально-эпидуральная анестезия (ДКСЭА) с фиксацией эпидурального катетера в подкожном канале при операциях по поводу переломов костей нижней конечности. Всем пациентам проводилась послеоперационная эпидуральная анальгезия. Разработан способ оценки степени наружной дислокации эпидурального катетера и алгоритм действий при обнаружении дислокации эпидурального катетера. При смене фиксирующей асептической наклейки проводилась оценка степени дислокации эпидурального катетера и при обнаружении выраженной дислокации предпринимались дополнительные меры для усиления фиксации эпидурального катетера.</p> <p><italic><bold>Результат</bold></italic>. Использование способа оценки степени наружной дислокации эпидурального катетера и выполнение алгоритма действий при обнаружении дислокации эпидурального катетера позволили провести качественное послеоперационное обезболивание 61 пациенту. У 10 пациентов при выявлении выраженной дислокации и при угрозе выпадения эпидурального катетера (дислокация 4–5-й степени, 15–30 мм) для дополнительной фиксации были использованы специальные фиксирующие устройства «Epi-Fix», что позволило продолжить проведение эпидуральной анальгезии. В 1-м случае (1,61%) эпидуральную анальгезию пришлось прекратить, т.к. через 48 ч была установлена 6-я степень дислокации эпидурального катетера (33 мм) и катетер был удалён. Послеоперационное обезболивание продолжено введением нестероидных противовоспалительных препаратов.</p> <p><italic><bold>Выводы</bold></italic>. Использование способа оценки степени наружной дислокации эпидурального катетера в ежедневной практике врача анестезиолога-реаниматолога позволяет оценить риск ухудшения и прекращения проводимого эпидурального обезболивания и принять меры для недопущения этого.</p></trans-abstract><kwd-group xml:lang="en"><kwd>two-level combined spinal-epidural anesthesia</kwd><kwd>dislocation of an epidural catheter</kwd><kwd>a method for assessing the degree of dislocation of an epidural catheter</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>комбинированная двухуровневая спинально-эпидуральная анестезия</kwd><kwd>дислокация эпидурального катетера</kwd><kwd>способ оценки степени дислокации эпидурального катетера</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">Ovechkin AM, Bayalieva AZ, Ezhevskaya AA, et al.
