Our study includes 75 newborns with malformations of the gastrointestinal tract, diaphragmatic hernias, gastroschisis, necrotizing enterocolitis and sacrococcygeal teratomas treated after surgery in the ICU. The Kidney Disease: Improving Global Outcomes (nKDIGO) scale was used to detect AKI. To assess the fluid overload, the ratio of the difference between the introduced and released liquid and entering the ICU weight was used (in %). Significant overload was adopted value more than 5%. The indicator “injected fluid” consisted of the volume of infusion and enteral nutrition. The indicator of “released fluid” included diuresis, fluid loss from the gastrointestinal tract, intestinal stomas, and drainages.</p> <p><bold>Results. </bold>The frequency of AKI was 28.0% (21 of 75). The average time of AKI development from the moment of surgical intervention was 5.9 ± 3.29 days. The duration of ICU stay after surgery was 8.0 [5.0; 16.0] days. In 18 of 75 (24%) children, the fluid overload of more than 5% was observed on the 1st postoperative day. In 12 out of 75 (16%) children, the fluid overload of more than 5% was observed on the 2<sup>nd</sup> postoperative day. A fluid overload of more than 5%, observed on the 1<sup>st</sup> day after the operation, was associated with a longer ICU stay. The rate of AKI is higher when a fluid overload of more than 5% on the 2<sup>nd</sup> day after surgery was observed.</p> <p><bold>Conclusion. </bold>Severe fluid overload can be a significant factor of the AKI development. Fluid overload more then 5% on the 2<sup>nd</sup> day after surgery may lead to an increase in the incidence of AKI. Liquid overload more then 5% on the 1<sup>st</sup> day after surgery may lead to an increase in the length of ICU stay. In newborns, it is necessary to take into account the fluid load at the first two days after the operation and correct the infusion therapy in case of fluid overload detection.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Выявить связь между перегрузкой жидкостью у детей, получавших инфузионную терапию в послеоперационном периоде в условиях хирургического отделения реанимации и интенсивной терапии (ОРИТ), развитием острого почечного повреждения (ОПП) и продолжительностью пребывания в ОРИТ<italic>.</italic></p> <p><bold>Методы.</bold> Было проведено ретроспективное когортное обсервационное исследование, включающее 75 новорожденных с пороками развития желудочно-кишечного тракта, диафрагмальными грыжами, гастрошизисом, некротизирующим энтероколитом и тератомами крестцово-копчиковой области, получавших лечение в ОРИТ после оперативного вмешательства. Для выявления ОПП использовали шкалу Kidney Disease: Improving Global Outcomes (nKDIGO). Для оценки перегрузки жидкостью использовали отношение разности введенной и выделенной жидкости к весу при поступлении в ОРИТ, выраженное в процентах. Значимой перегрузкой было принято значение более 5 %. Показатель «введенная жидкость» складывался из объема инфузии и энтерального питания. Показатель «выделенной жидкости» включал диурез, потери по желудочному зонду, кишечным стомам и дренажам.</p> <p><bold>Результаты. </bold>Частота ОПП составила 28,0 % (21 из 75). Среднее время развития ОПП с момента оперативного вмешательства составило 5,9 ± 3,29 сут. Длительность пребывания в ОРИТ после перенесенного оперативного вмешательства составила 8,0 [5,0; 16,0] сут. У 18 из 75 (24 %) детей наблюдалась перегрузка жидкостью более 5 % в 1-е послеоперационные сутки. У 12 из 75 (16 %) детей наблюдалась перегрузка жидкостью более 5 % во 2-е послеоперационные сутки. Перегрузка жидкостью более 5 %, наблюдавшаяся на 1-е сутки после операции, была связана c большей длительностью пребывания в ОРИТ. Вероятность развития ОПП выше при перегрузке жидкостью более 5 % на 2-е сутки после операции.</p> <p><bold>Заключение.</bold> Выраженная перегрузка жидкостью может быть значимым фактором развития ОПП. Перегрузка жидкостью более 5 % на 2-е сутки после операции может приводить к увеличению частоты развития ОПП. Перегрузка жидкостью более 5 % в 1-е сутки после операции может приводить к увеличению продолжительности госпитализации. У новорожденных необходим учет жидкостной нагрузки в первые двое суток после операции и коррекция инфузионной терапии в случае обнаружения перегрузки жидкостью.</p></trans-abstract><kwd-group xml:lang="en"><kwd>acute kidney injury</kwd><kwd>Risk Factors</kwd><kwd>Fluid overload</kwd><kwd>Adverse outcomes</kwd><kwd>Critically ill neonates</kwd><kwd>Intensive care</kwd><kwd>Length of ICU stay</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>острое почечное повреждение</kwd><kwd>факторы риска</kwd><kwd>перегрузка жидкостью</kwd><kwd>неблагоприятные исходы</kwd><kwd>критически больные новорожденные</kwd><kwd>интенсивная терапия</kwd><kwd>продолжительность пребывания в отделении интенсивной терапии</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>McCann M, Soriano S.
