Objective To explore the prognostic value of N-terminal pro-brain natriuretic peptide ( NT-pro-BNP) levels in critically ill infants. Methods Eighty-one critically ill infants were enrolled from January 2013 to January 2014 in pediatric intensive care unit. The minimum of pediatric critical illness score ( PCIS) and the number of dysfunction organs were calculated within 24 hour after admission. According to PCIS,the critically ill infants were divided into extremely critical group(PCIS≤70,n=25),critical group (PCIS 71-80,n=30)and non-critical group(PCIS>80,n=26). According to the prognosis,the critically ill infants were divided into survival group (n=68)and death group(n=13). The serum NT-pro-BNP levels were determined on the first day,third day and convalescent phase. The relationships of serum NT-pro-BNP levels with PCIS and the number of dysfunction organs and prognosis were observed. Results The study showed statistical significances of serum NT-pro-BNP levels among the extremely critical group, critical group and non-critical group,whether on the first day,or on the third day and convalescent phase(P<0. 01). There were statistical significances of serum NT-pro-BNP levels among different stages of the disease in each group(P<0. 01). Compared with survival group,PCIS was significantly lower and the serum NT-pro-BNP levels and the number of dysfunction organs were significantly higher in death group. The serum NT-pro-BNP level on the third day was higher than that on the first day in death group ( P<0. 01 ) , while no significant difference was found in survival group. The serum NT-pro-BNP levels on the first day and the third day and PCIS were negatively correlated(r= -0. 59,P<0. 01;r= -0. 66,P<0. 01). The serum NT-pro-BNP levels on the first day and the third day and the number of dysfunction organs were positively correlated(r=0. 40,P<0. 05;r=0. 57,P<0. 01). Conclusion The serum NT-pro-BNP levels of the critically ill infants are correlated with disease severity,and can be useful for assessing the severity of critical illness.
