Abstract:

Objective To evaluate the changes of perioperative N-terminal pro-B-type natriuretic peptide(NT-proBNP) and procalcitonin(PCT) levels in children with simple and complex congenital heart disease(CHD). Methods Totally,96 children with CHD(≤6 years old)(38 simple CHD patients and 58 complex CHD patients) who underwent cardiac surgery in Xinhua Hospital of Shanghai Jiao Tong University School of Medicine from January 2020 to November 2021 were enrolled. The clinical data of these CHD patients and the NT-proBNP and PCT results at 24 h before operation(T1) and 4 h after operation(T2),24 h after operation(T3) and 48 h after operation(T4)were collected. The changes of perioperative NT-proBNP and PCT were analyzed,and the correlations were evaluated. The perioperative NT-proBNP and PCT levels in predicting the prolongation of intensive care unit(ICU) stay and hospital stay were evaluated by Logistic regression analysis. Results The levels of NT-proBNP and PCT at T3 and T4 were higher than those at T1 and T2. The levels of NT-proBNP at T1,T2,T3 and T4 were negatively correlated with age and body mass(P<0.01),and that in complex CHD children was higher than that of simple CHD children. NT-proBNP levels at T3 and T4 were positively correlated with extracorporeal circulation time and aortic occlusion time(P<0.05),and NT-proBNP at T4 was positively correlated with operation time(P<0.05). At T4,PCT was negatively correlated with age and body mass(P<0.05),and that in complex CHD children was higher than that in simple CHD children. Multivariate Logistic regression analysis showed that NT-proBNP at T3 [odds ratio(OR)=1.23] and PCT at T4(OR=1.13) were independent factors for the length of ICU stay. NT-proBNP at T3(OR=1.12) and PCT at T4(OR=1.12) were independent factors on the length of hospital stay. Conclusions Perioperative NT-proBNP and PCT levels in children with CHD are increased and then decreased after operation,and they play roles in predicting the prolongation of ICU stay and hospital stay.
