【摘要】：目的探讨早产儿动脉导管未闭超声参数预测早期自然关闭的价值。方法对2013年10月至2014年10月在重庆市妇幼保健院出生的早产儿110例进行前瞻性研究,早产儿分别于1、3、7d行超声心动图检查,首次检查测量左心房收缩末期内径(LA)、主动脉根部内径(AO)及动脉导管相关参数分流束最细处宽度及导管最大分流速。出生后7d内动脉导管仍开放者为动脉导管未闭组;7d内动脉导管自然关闭者为对照组,并进行组间比较。结果 (1)早产儿动脉导管于3、7d内自然关闭率分别为70.9%(78/110)、78.2%(86/110);(2)动脉导管未闭组与对照组对比:LA/AO大于对照组(P0.01);分流束最细处宽度大于对照组(P0.01);最大分流速低于对照组(P0.05);(3)动脉导管未闭早期自然关闭LA/AO、分流束导管最细处宽度及导管最大分流速的最佳临界点值分别为1.32mm、2.56mm及185.5cm/s。结论彩超对预测早产儿动脉导管未闭早期能否自然关闭具有重要意义。
[Abstract]:Objective to evaluate the value of ultrasonic parameters in predicting early spontaneous closure of patent ductus arteriosus in premature infants. Methods A prospective study was conducted on 110 premature infants born in Chongqing Maternal and Child Health Care Hospital from October 2013 to October 2014. Left atrial end-systolic diameter (LAA), aortic root diameter (AOA), the minimum width of duct-related shunt bundle and the maximum vessel velocity were measured for the first time. The patients with patent ductus arteriosus who were still open within 7 days after birth were the control group with natural closure of the ductus arteriosus within 7 days after birth, and the comparison was made between the two groups. Results 1) the natural closure rate of ductus arteriosus in premature infants was 70.9% / 78 / 110 / 78.2% / 78.2% / 110 / 2 respectively within 3 days) compared with the control group, the ratio of 10% LA-AO in the patent ductus arteriosus group was greater than that in the control group (P0.01), the width of the shunt bundle was larger than that in the control group (P0.01), and the maximum flow velocity was lower than that in the control group (P0.05 / 1). In the early stage of patent ductal closure, the optimum critical points for the thinnest width of shunt bundle and the maximum fractional velocity are 1.32mm / 2.56mm and 185.5 cm / s, respectively. Conclusion Color Doppler ultrasonography is of great significance in predicting the spontaneous closure of patent ductus arteriosus in premature infants.
