Early diagnosis value of N-terminal pro-brain natriuretic peptide in children with acute lung injury/acute respiratory distress syndrome / 中华实用儿科临床杂志

ABSTRACT

Objective To study the early diagnostic value of N-terminal pro-brain natriuretic peptide (NT-pro-BNP) for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) in children and its influence on prognosis.Methods Fifty-two children with ALI/ARDS were selected as the experiment group,and 36 children with cardiac disease merging dyspnea were selected as the control group.The serum levels of NT-pro-BNP were measured in the 2 groups.The pediatric critical illness score(PCIS),lung injury score (LIS) and 28-day mortality were analyzed in the experiment group.The serum level of NT-pro-BNP,and the different condition and prognosis were compared in 2 groups,and the difference of the NT-pro-BNP levels were compared in children with ALI/ARDS.Results The NT-proBNP levels in experiment group were significantly higher than the control group (P ＜ 0.05).But the NT-pro-BNP levels in children with cardiaogenic pulmonary edema were significantly higher than ALI/ARDS(P ＜ 0.05).The NT-pro-BNP levels of the children who died in 28 d,or with LIS ＞ 2.5 scores or PCIS≤70 scores were higher than that of children who were survived,or with LIS ≤ 2.5 scores or PCIS ＞ 70 scores (P =0.001,0.013,0.002).The NT-pro-BNP levels were negatively correlated with PCIS(P ＜ 0.05),and the NT-pro-BNP levels were positively correlated with the 28-day mortality and LIS(all P ＜ 0.05).Conclusions The measurement of serum NT-pro-BNP can help to evaluate the severity and prognosis of ALI/ARDS children.
