При этом незаслуженно забытым параметром при диагностике метаболического ацидоза является анионный пробел плазмы. Целью исследования было определить возможности использования анионного пробела плазмы для дифференциальной диагностики метаболического ацидоза у новорожденных с неонатальным сепсисом. Для реализации поставленной цели проведено обследование пациентов отделения реанимации и интенсивной терапии для новорожденных. Критериями включения в исследование были период новорожденности, наличие неонатального сепсиса, лабораторные признаки метаболического ацидоза. Всего под наблюдением находились 17 новорожденных детей с неонатальным сепсисом. Диагноз неонатального сепсиса устанавливался на основании подозреваемой или документированной инфекции в сочетании с остро возникшей органной дисфункцией, о развитии которой судили по индексу шкалы pSOFA на 2 балла и более от базового значения. Метаболический ацидоз был выявлен у 5 пациентов. У новорожденных с неонатальным сепсисом чаще регистрировался метаболический ацидоз с ростом анионного пробела плазмы, что обусловлено лактатным ацидозом в результате накопления молочной кислоты как маркера тканевой гипоксии. Уменьшение анионного пробела плазмы выявлялось реже и могло свидетельствовать о потерях бикарбонатного аниона через желудочно-кишечный тракт или в результате гипоальбуминемии. Показано, что анионный пробел плазмы может служить дополнительным информационным критерием для характеристики метаболического ацидоза. Расчет анионного пробела плазмы является недорогим и эффективным инструментом, способным помочь провести дифференциальный диагноз метаболического ацидоза у новорожденных с неонатальным сепсисом для назначения адекватной интенсивной терапии.</p></abstract><trans-abstract xml:lang="en"><p> In critical conditions, one of the most common acid-base disorders is metabolic acidosis. At the same time, an undeservedly forgotten parameter in the diagnosis of metabolic acidosis is the plasma anion gap. Purpose of the study: to determine the possibility of using the plasma anion gap for differential diagnosis of metabolic acidosis in newborns with neonatal sepsis. To achieve this goal, the patients of the intensive care unit and intensive care unit for newborns were examined. Inclusion criteria: neonatal period, presence of neonatal sepsis, laboratory signs of metabolic acidosis. In total, 17 newborns with neonatal sepsis were under observation. The diagnosis of neonatal sepsis was established on the basis of a suspected or documented infection in combination with acute organ dysfunction, the development of which was judged by the pSOFA index by 2 points or more from the baseline value. Metabolic acidosis was identified in 5 patients. In newborns with neonatal sepsis, metabolic acidosis was more often recorded with an increase in the plasma anion gap, which is due to lactic acidosis as a result of the accumulation of lactic acid, as a marker of tissue hypoxia. A decrease in the plasma anion gap was detected less frequently and could indicate a loss of bicarbonate anion through the gastrointestinal tract or as a result of hypoalbuminemia. It has been shown that the plasma anion gap can serve as an additional information criterion for characterizing metabolic acidosis. Plasma anion gap calculation is an inexpensive and effective tool that can help differentiate metabolic acidosis in newborns with neonatal sepsis for adequate intensive care.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кислотно-основное состояние</kwd><kwd>метаболический ацидоз</kwd><kwd>лактатацидоз</kwd><kwd>кетоацидоз</kwd><kwd>ионы сыворотки крови</kwd><kwd>анионный пробел плазмы</kwd><kwd>бикарбонатный анион</kwd><kwd>дети</kwd><kwd>новорожденные</kwd><kwd>сепсис</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acid-base state</kwd><kwd>metabolic acidosis</kwd><kwd>lactic acidosis</kwd><kwd>ketoacidosis</kwd><kwd>serum ions</kwd><kwd>plasma anion gap</kwd><kwd>bicarbonate anion</kwd><kwd>children</kwd><kwd>newborns</kwd><kwd>sepsis</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">Kraut J.
