Abstract:
Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.
