采用全自动化学免疫系统和全自动生化分析仪测定新生儿窒息组92例和对照组40例血清心肌肌钙蛋白(cTn)I水平,探讨窒息后血清cTnI变化及其临床应用价值。结果显示,各组窒息新生儿血清cTnI浓度均明显升高,差异显著(P<0.05)。围产期窒息组无心脏损害和有心脏损害的患儿血清cTnI浓度比较有显著差异(P<0.05),且与有重度心脏损害患儿血清cTnI比较,差异更显著(P<0.01)。因此,围产期窒息后,血清cTnI水平增高,其可作为判断围产期窒息后所导致心肌损害的诊断指标之一。
Serum cardiac troponin (cTn) I level was measured in 92 neonates with asphyxia group and 40 in control group by automatic chemical immunization system and automatic biochemical analyzer, and the changes of serum cTnI in asphyxia and its clinical value were discussed. The results showed that serum concentrations of cTnI in neonatal asphyxia group were significantly increased, the difference was significant (P <0.05). Serum levels of cTnI in children with perinatal asphyxia had no significant difference (P <0.05), and the difference was significant (P <0.01) compared with that of children with severe heart damage. Therefore, perinatal asphyxia, serum cTnI levels increased, which can be used as a judge perinatal asphyxia myocardial damage caused by one of the diagnostic indicators.
