Abstract
The issue of acute kidney injury in children after cardiac surgery remains topical despite the constant development of modern technologies and methods. Complications arising from cardiac surgery in children have serious adverse effects, leading to increased length of stay in the infant intensive care unit and increased mortality. The aim of study: to analyse modern concepts on the role of perioperative risk factors and prognostic value of leading biomarkers in the development of acute kidney injury in children after cardiac surgery. The review was prepared using the method of searching literature on databases Scopus, PubMed, MedLine, Cyberleninka, Google Scholar, Cochrane library, TripDataBase for the period 2012-2022. Research in the academic setting has revealed that there are several risk factors associated with the development of acute kidney injury in children after cardiac surgery. These factors include early patient age, duration of artificial circulation, complexity of surgery, use of artificial ventilation and inotropic support. Despite the importance of these studies, they have not fully explored many of the issues that have recently become relevant and related to the search for new biomarkers. These biomarkers play an important role in early diagnosis and treatment of acute kidney injury.
