【摘要】 目的了解不同胎龄早产儿动脉导管未闭(PDA)的发病率。方法对本院NICU收治的早产儿行常规心脏彩超检查,按胎龄分组,计算每组PDA发生率。结果 2427例早产儿有581例发生了PDA,按组计算发病率为:<28周86.7%,28周67.4%,29周51.8%,30周43.6%,31周36.7%,32周30.1%,33周21.2%,34周18.1%,35周12.9%,36周6.7%。结论本研究提示胎龄越小,PDA发病率越高;本研究得出不同胎龄PDA发病率的详细数据,为以后开展相关研究积累了资料。更多还原

【Abstract】 Objective To understand the incidence of PDA in premature infants with different gestational age.Methods Preterm children admitted in NICU of our hospital were routinely examined by heart color Doppler ultrasound and devided into groups according to gestational age.The incidence of PDA in each group was calculated.Results In 2427 cases of premature children,there were 581 cases of PDA.And the incidence was calculated by group,with <28 weeks 86.7%,28 weeks 67.4%,29 weeks 51.8%,30 weeks 43.6%,31 weeks 36.7%,32 weeks 30.1%,33 weeks 21.2%,34 weeks18.1%,35 weeks 12.9%and 36 weeks 6.7%.Conclusion It was found that the smaller the gestational age,the higher the incidence of PDA.And the detailed data of PDA incidence of different gestational age were obtained to accumulate information for carrying out related research in the future.更多还原
