【摘要】：目的探讨超声血流参数预测早产儿动脉导管早期是否自然关闭的价值。方法对2013年10月至2014年12月在重庆市妇幼保健院住院且生后24h内进行超声心动图检查有动脉导管未闭(PDA)的早产儿130例进行前瞻性研究,分别于72h及7d对早产儿行超声心动图检查,7d内动脉导管未自然关闭者为动脉导管早期未自然关闭组(PDA组);自然关闭者为动脉导管早期自然关闭组(对照组),对两组患者进行组间比较。首次超声检查(24h内)测量收缩期降主动脉与肺动脉的压差、肺动脉收缩压及卵圆孔分流速度。结果 (1)PDA组与对照组比较:1降主动脉与肺动脉的压差低于对照组(P0.001);2肺动脉收缩压高于对照组(P0.001);3卵圆孔分流速低于对照组(P0.05);(2)利用降主动脉与肺动脉的压差、肺动脉收缩压、卵圆孔分流速预测早产儿动脉导管早期自然关闭的最佳临界点值分别为:19.69mm Hg、33.76mm Hg及57.16cm/s。结论超声血流参数对预测早产儿动脉导管早期能否自然关闭具有重要意义。
[Abstract]:Objective to evaluate the value of ultrasonic blood flow parameters in predicting early closure of ductus arteriosus in premature infants. Methods from October 2013 to December 2014, 130 premature infants with patent ductus arteriosus (PDAs) who were hospitalized in Chongqing Maternal and Child Health Care Hospital and were examined by echocardiography within 24 hours after birth were studied prospectively. Echocardiography was performed on premature infants at 72 hours and 7 days, respectively. The group of premature infants with unnaturally closed ductus arteriosus within 7 days was the group of PDA and the group of patients with natural closure of ductus arteriosus was the group of early natural closure of ductus arteriosus (control group, two groups). The patients in the group were compared between groups. The pressure difference of descending aorta and pulmonary artery, systolic pressure of pulmonary artery and shunt velocity of foramen ovale were measured. Results compared with the control group, the pressure difference between the descending aorta and the pulmonary artery in the control group was lower than that in the control group. The systolic pressure of the pulmonary artery was higher than that of the control group (P 0.001) the mean velocity of the porus ovale was lower than that of the control group (P 0.05). The systolic pressure of the pulmonary artery was obtained by using the pressure difference between the descending aorta and the pulmonary artery. The optimal critical point for predicting the early natural closure of ductus arteriosus in premature infants was: 1 19.69 mm Hg 33.76 mm Hg and 57.16 cm / s respectively. Conclusion Ultrasonic blood flow parameters are important in predicting early closure of ductus arteriosus in premature infants.
