Ultrasonic cardiac output monitor for evaluation of cardiac function in neonatal sepsis / 中国小儿急救医学

ABSTRACT

Objective To monitor the change of cardiac function in neonatal sepsis by using the ultrasonic cardiac output monitor(USCOM).Methods Thirty two cases of mild sepsis neonates and nineteen cases of severe sepsis neonates were enrolled and thirty three cases of healthy neonates were enrolled in the control group.The cardiac output indicators of three groups were monitored by USCOM.The differences of cardiac function among 3 groups and the changes of candiac function after treatment in septic neonates were investigated.Results Compared with control group,the heart rate,systemic vascular resistance of mild sepsis neonates group and severe sepsis neonates group were significantly higher,and the cardiac output,systolic volume,cardiac index,aortic peak velocity were significantly lower,the differences were statistically significant(P<0.05).The cardiac index,cardiac output were significactly lower in severe sepsis neonates group than those in mild sepsis neonates group(P<0.05).After improving cardiac function treatment,all cardiac function indexes of sepsis neonates were improved than before treatment,the differences were statistically significant(P<0.05).Conclusion There are significant cardiac function changes in sepsis neonates.The cardiac function and overall circulation state monitoring by USCOM is fast and convenient,and USCOM can provide the basis for treatment and evaluation of the neonatal sepsis.
