Abstract

Background: The imbalance between oxygen supply and the body's need for oxygen is one of the causes leading to some complications in resuscitation after open heart surgery. Low ScvO2 index is one of the valuable indicators in predicting some major events after open heart surgery. Objectives: Survey on the value of ScvO2 index at different times after open heart surgery in children with congenital heart disease at the VietNam National Children's Hospital. Methods: The study was conducted on 119 congenital heart disease patients undergoing open heart surgery in order to investigate the distribution of ScvO2 concentrations by the times, weight and RACHS-1 score, time of aortic clamp, time of cardiopulmonary bypass at 4 time points: immediately after leaving the Surgical Cardiac Intensive Care Unit (T1), after 6h (T2), after 12h, after (T3), after 24h (T4). Results: ScvO2 index were the lowest at T2 after 6 hour arive ICU (54.42±12.76%), decreased at T3, T4 with p<0,01; ScvO2 index loss was lower in the group under 5kg at time T2, T3 and T4 with p<0.05; ScvO2 index at time T2 decreased lower in the group with high Risk adjustment for congenital heart surgery (RACHS-1≥3) with p <0.05. Conclusion: ScvO2 index was lowest at T2 time after surgery, ScvO2 index lower in group under 5kg and group with high RACHS-1.
