The use of balanced crystalloid solutions in combination with an optimized infusion regimen may improve metabolic and hemodynamic parameters as well as myocardial contractility.</p> <p><bold>AIM:</bold> This work aimed to evaluate the effectiveness of an optimized restrictive infusion regimen with balanced crystalloid solutions in neonates and infants during the early postoperative period after cardiac surgery for congenital heart defects.</p> <p><bold>METHODS:</bold><bold><italic> </italic></bold>This prospective cohort study included 61 children with transposition of the great arteries and total anomalous pulmonary venous return, who underwent radical cardiac surgery. Patients were allocated into groups according to the type of solution and infusion protocol used: the control group received 0.9% sodium chloride solution using a standard regimen, whereas the main group received Ringer’s balanced solution according to the optimized method (1 ml/[kg × h] + 1 ml/[kg × h] for inotropic support).</p> <p><bold>RESULTS:</bold><bold> </bold>Patients treated with the balanced solution under the optimized regimen demonstrated more pronounced improvements in pH and base deficit, stable potassium, sodium, and chloride levels, less pronounced tachycardia, and normalization of central venous pressure. Echocardiographic parameters at 24 hours indicated improved end-diastolic volume, end-diastolic index, and ejection fraction. Extubation time was reduced by 20.2%, and length of stay in intensive care units was reduced by 14.3%.</p> <p><bold>CONCLUSION:</bold> The combination of balanced crystalloids with a restrictive infusion regimen in neonates and infants after correction of congenital heart defects promotes a more physiological restoration of homeostasis, reduces the need for inotropic support, and improves cardiohemodynamic parameters in the early postoperative period.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Выбор режима инфузионной терапии у новорожденных и младенцев после кардиохирургических операций остается актуальной задачей. Использование сбалансированных кристаллоидных растворов в сочетании с оптимизированным режимом введения может способствовать улучшению метаболических и гемодинамических параметров, а также сократительной функции миокарда.</p> <p><bold>Цель исследования.</bold> Провести оценку эффективности оптимизированного ограничительного режима инфузионной терапии с применением сбалансированных кристаллоидных растворов у новорожденных и младенцев в раннем послеоперационном периоде после кардиохирургических вмешательств по поводу врожденных пороков сердца.</p> <p><bold>Методы.</bold> В проспективное когортное исследование включен 61 ребенок с транспозицией магистральных сосудов и тотальным аномальным дренажом легочных вен, перенесший радикальные кардиохирургические вмешательства. Пациенты были разделены на группы в зависимости от применяемого раствора и схемы инфузии: в контрольной группе применяли 0,9% раствор хлорида натрия по традиционной схеме, в основной — сбалансированный раствор Рингера по оптимизированному методу [1 мл/(кг×ч) + 1 мл/(кг×ч) на инотропную поддержку].</p> <p><bold>Результаты.</bold> У пациентов, получавших сбалансированный раствор по оптимизированной схеме, отмечались более выраженные положительные изменения водородного показателя и дефицита оснований, стабильный уровень калия, натрия и хлора, менее выраженная тахикардия и нормализация центрального венозного давления. Эхокардиографические параметры через 24 ч указывали на улучшение конечного диастолического объема, конечного диастолического индекса и фракции выброса. Время экстубации было сокращено на 20,2%, а длительность пребывания в отделениях интенсивной терапии — на 14,3%.</p> <p><bold>Заключение.</bold> Сочетание сбалансированных кристаллоидов с ограничительным режимом инфузионной терапии у новорожденных и младенцев после коррекции врожденных пороков сердца способствует более физиологичному восстановлению гомеостаза, снижению потребности в инотропной поддержке и улучшению показателей кардиогемодинамики в раннем послеоперационном периоде.</p></trans-abstract><trans-abstract xml:lang="zh"><p><bold>论证</bold>。新生儿和婴儿心脏外科手术后输液方案的选择仍是一项重要任务。应用平衡晶体液并结合优化的输注模式，可改善代谢和血流动力学参数及心肌收缩功能。</p> <p><bold>目的</bold>。评估平衡晶体液优化限制性输液方案在新生儿和婴儿先天性心脏病心脏外科手术后早期阶段的有效性。</p> <p><bold>方法</bold>。前瞻性队列研究纳入61名患儿，包括大动脉转位和全肺静脉异位引流，均接受根治性心脏手术。患者根据所用溶液和输液方案分为两组：对照组采用0.9%氯化钠溶液，按常规方案输入；实验组采用优化方法输入平衡林格液[1 ml/(kg×h) + 1 ml/(kg×h)用于正性肌力支持]。</p> <p><bold>结果</bold>。接受优化方案下平衡晶体液治疗的患儿，其pH和碱缺乏改善更明显，血钾、钠、氯水平保持稳定，心动过速减轻，中心静脉压恢复正常。术后24小时超声心动图提示舒张末期容积、舒张末期指数及射血分数改善。拔管时间缩短20.2%，重症监护病房停留时间缩短14.3%。</p> <p><bold>结论</bold>。平衡晶体液联合限制性输液方案有助于机体内环境的生理性恢复，降低正性肌力药物需求，并改善新生儿及婴儿先天性心脏病根治术后早期的心脏血流动力学参数。</p></trans-abstract><kwd-group xml:lang="en"><kwd>neonates</kwd><kwd>infusion therapy</kwd><kwd>balanced solutions</kwd><kwd>optimized regimen</kwd><kwd>cardiac surgery</kwd><kwd>hemodynamics</kwd><kwd>echocardiography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>новорожденные</kwd><kwd>инфузионная терапия</kwd><kwd>сбалансированные растворы</kwd><kwd>оптимизированный режим</kwd><kwd>кардиохирургия</kwd><kwd>гемодинамика</kwd><kwd>эхокардиография</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>新生儿</kwd><kwd>输液治疗</kwd><kwd>平衡晶体液</kwd><kwd>优化模式</kwd><kwd>心脏外科</kwd><kwd>血流动力学</kwd><kwd>超声心动图</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bouma BJ, Mulder BJM.
