The significance of this issue is underestimated, with a third of these patients developing a neuropathic component of chronic pain syndrome.</p> <p><bold>AIM: </bold>To assess the severity of acute and chronic postoperative pain following sternotomy and to identify predictors of the neuropathic component of chronic pain syndrome.</p> <p><bold>MATERIALS AND METHODS: </bold>Out of 115 patients who underwent elective coronary artery bypass grafting (CABG) randomized according to method of anesthesia, two study groups were formed based on the results of a telephone survey: a general anesthesia group (GA, <italic>n </italic>=28) and a combined anesthesia group (CA, <italic>n </italic>=34). As part of the <italic>post hoc </italic>analysis, a logistic regression model was built to predict chronic neuropathic pain syndrome based on gender, age, anesthesia method, and factors assessing the severity of the perioperative period and myocardial impairment.</p> <p><bold>RESULTS: </bold>Chronic postoperative pain syndrome was identified in 25.8% of patients, with a neuropathic component confirmed in 19.4% of cases. Pain severity at rest in the GA and CA groups was 2.0 (1.0) and 3.0 (3.0) points on a numeric rating scale one hour after extubation, and 2.0 (2.0) and 2.0 (2.0) points by the end of the first postoperative day (<italic>p </italic>=0.193 and 0.610, respectively). The logistic regression model achieved an AUROC of 0,82 (95% CI 0,68–0,96) with χ <sup>2 </sup>(10)=10.62, <italic>p </italic>=0.39.</p> <p><bold>CONCLUSIONS: </bold>Neuropathic pain was diagnosed in 19.4% of patients following CABG. The use of regional anesthesia and the severity of acute pain did not impact the development of neuropathic pain syndrome in the long-term period after surgery. The proposed model for predicting the neuropathic component of chronic pain syndrome after CABG requires further improvement.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>На фоне повышения безопасности и качества раннего послеоперационного периода 6,9٪ пациентов после стернотомии испытывают хроническую боль в зоне операции. Актуальность её недооценена, у трети пациентов диагностируется нейропатический компонент хронического болевого синдрома.</p> <p><bold>Цель. </bold>Оценить выраженность острой и хронической послеоперационной боли после стернотомии и выявить предикторы нейропатического компонента хронического болевого синдрома.</p> <p><bold>Материалы и методы. </bold>Из 115 пациентов, перенёсших плановое аортокоронарное шунтирование и рандомизированных согласно методикам анестезии, по результатам телефонного анкетирования сформировано 2 исследуемые группы — общей (<italic>n</italic><italic> </italic>=28) и комбинированной анестезии (<italic>n</italic><italic> </italic>=34). В рамках <italic>post</italic><italic> </italic><italic>hoc</italic><italic> </italic>анализа построена модель логистической регрессии для прогнозирования хронического нейропатического болевого синдрома на основании пола, возраста, методики анестезии и факторов, оценивающих тяжесть периоперационного периода и выраженность миокардиального повреждения.</p> <p><bold>Результаты. </bold>У 25,8% пациентов диагностирован хронический послеоперационный болевой синдром, у 19,4% пациентов подтверждён его нейропатический характер. Выраженность боли в покое в группах общей и комбинированной анестезии составила 2,0 (1,0) и 3,0 (3,0) балла по цифровой рейтинговой шкале через час после экстубации и 2,0 (2,0) и 2,0 (2,0) балла в конце первых послеоперационных суток (<italic>p</italic><italic> </italic>=0,193 и 0,610 соответственно). Модель логистической регрессии имеет AUROC 0,837 (95% ДИ 0,713–0,961) при χ <sup>2 </sup>(10)=13,43, <italic>p</italic><italic> </italic>=0,266.</p> <p><bold>Заключение. </bold>После аортокоронарного шунтирования у 19,4% пациентов диагностирована нейропатическая боль. Применение методик регионарной анестезии и выраженность острой боли не влияют на формирование нейропатического болевого синдрома в отдалённом послеоперационном периоде. Предложенная модель прогнозирования нейропатического компонента хронического болевого синдрома после аортокоронарного шунтирования требует доработки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>regional anesthesia</kwd><kwd>chronic postoperative pain syndrome</kwd><kwd>neuropathic pain</kwd><kwd>sternotomy</kwd><kwd>cardiac surgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>регионарная анестезия</kwd><kwd>хроническая послеоперационная боль</kwd><kwd>нейропатическая боль</kwd><kwd>стернотомия</kwd><kwd>кардиохирургия</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">McNichols B, Spratt JR, George J, et al.
