В исследование включены 129 взрослых пациентов, перенесших операции на сердце в условиях ИК. Изучены показатели кислотно-основного состояния (КОС) крови, маркеры системного воспаления, доставка и потребление кислорода, параметры гемодинамики, клиническое течение послеоперационного периода.</p></sec><sec><title>Результаты</title><p>Результаты. Нарушения КОС развились в 73,6 % случаев, у 51,2 % пациентов – МетАц. В структуре МетАц на долю лактат-ацидоза пришлось 92,4 %, в 7,6 % это был гиперхлоремический ацидоз. Метаболический лактат-ацидоз представлен двумя формами. В 14,7 % это нарушение КОС было вызвано синдромом малого сердечного выброса и характеризовалось сниженными показателями доставки кислорода и производительности сердца. В 49,2 % случаев лактат-ацидоз развился на фоне системного воспалительного ответа и ассоциирован с высокой доставкой и низкой экстракцией кислорода, а также с повышенной производительностью сердца и вазоплегией. Пациенты с данными нарушениями имели бóльший уровень лейкоцитоза через 24 ч после окончания операции, выше продолжительность респираторной поддержки, период лечения в отделении реанимации и интенсивной терапии и стационаре.</p></sec><sec><title>Заключение</title><p>Заключение. Метаболический лактат-ацидоз представлен двумя формами: лактат-ацидоз на фоне синдрома малого сердечного выброса и на фоне системного воспалительного ответа. Лактат-ацидоз является предиктором неблагоприятного исхода после операций на сердце с ИК, ассоциирован с риском развития послеоперационных осложнений и летальностью.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>Aim – determine a forms of metabolic acidosis (MetAc) after cardiac surgery with cardiopulmonary bypass (CPB). Estimate signiﬁcance of MetAc in an early postoperative period.</p><sec><title>Material and methods</title><p>Material and methods. We included the 129 adult cardiac surgery patients. We studied the indicators of acid-base blood status, markers of systemic inﬂammation, an oxygen delivery and consumption, the hemodynamic parameters, the clinical course of the postoperative period.</p></sec><sec><title>Results</title><p>Results. The acid-base disorders were found in 73.6 % of cases. The metabolic acidosis was in 51.2 % of cases: the lactate acidosis was in 92.4 % and the hyperchloremic acidosis was in 7.6 %. The metabolic lactate acidosis was represented by two forms: 1. the acid-base disorders due to a low cardiac output syndrome with a decrease in oxygen delivery and contractility (14.7 %); 2. the lactate acidosis due to a systemic inﬂammatory response syndrome (49.2 % of cases). It is associated with a high delivery and a low oxygen extraction, increased cardiac output and a vasoplegia. Patients with these disorders had a higher level of leukocytosis after 24 hours of the end the operation, had a longer duration of respiratory support and a long ICU stay and hospital stay.</p></sec><sec><title>Conclusion</title><p>Conclusion. The lactate acidosis is represented by two forms: the lactate acidosis associated with the low cardiac output syndrome and lactate acidosis associated with the systemic inﬂammatory response. The lactate acidosis is a predictor of adverse outcome after cardiac surgery with CPB and associated with a postoperative complications and a mortality.</p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кардиохирургия</kwd><kwd>метаболический ацидоз</kwd><kwd>лактат-ацидоз</kwd><kwd>искусственное кровообращение</kwd><kwd>гемодинамика</kwd><kwd>синдром малого сердечного выброса</kwd><kwd>системный воспалительный ответ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac surgery</kwd><kwd>metabolic acidosis</kwd><kwd>lactate acidosis</kwd><kwd>extracorporeal circulation</kwd><kwd>hemodynamics</kwd><kwd>small cardiac output syndrome</kwd><kwd>systemic inﬂammatory response</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Landoni G, Lomivorotov VV, Nigro Neto C et al.
