Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Aim: This article aims to investigate the dynamics of the total extracellular water of the body when performing modified ultrafiltration after artificial circulation.Methods: 50 patients were examined, from 1 to 8 years.Half of them -with congenital heart defects (the main group) under conditions of modified ultrafiltration of blood after artificial circulation, the other -a control group of children operated under conditions of artificial circulation, without performing a modified ultrafiltration of blood.Results: In the course of the study, the authors presented the drawings showing their own scheme for carrying out the modified ultrafiltration, the effect of modified ultrafiltration on the perioperative changes in the total extracellular water of the body in the control and main groups, as well as the perioperative dynamics of total extracellular water in 45% of the children in the main group.Particular attention is drawn to Table 1, which presents the numerical values of bioelectroimpedance determined in the study groups at different stages of the operation and in the postoperative period, and an assessment of its dynamic changes is given. Conclusion:The obtained results of the studies allow us to recommend a method of modified ultrafiltration of blood for correction of water metabolism disorders in children during heart operations with artificial circulation.In the conclusions, data analysis showed that carrying out artificial circulation promotes the accumulation of fluid in the extracellular extravascular space (an average of 25.8 ± 2.7%).Conducting a modified ultrafiltration of blood after an artificial circulation helps to prevent the accumulation of fluid in the extravasal space.
