目的探讨产前超声在先兆流产出血中的诊断价值,并进一步分析产前超声在保胎治疗后对妊娠结局的指导意义。方法选取2013年12月-2014年12月在该院初诊为早孕出血的患者120例为实验组,另选取同期体检正常孕妇40例为对照组,利用超声诊断仪(型号为ALOKA 4000)以3.6 MHz的频率进行超声检查,观察患者早孕胎膜后的出血状况,并分析保胎治疗后的疗效。结果对照组患者经超声诊断后均未出现先兆流产现象,实验组患者95例确诊为先兆流产,检出率达79.2%。超声观察确诊患者69例(72.6%)可见出血暗区,其中轻症36例(52.2%)、重症33例(47.8%)。对患者进行临床保胎治疗,轻症患者治疗成功率为80.6%,重症患者治疗成功率为39.4%,轻症患者与重症患者保胎成功率比较,差异有统计学意义(χ~2=15.280,P=0.001)。结论产前超声诊断可以有效地检查出早孕胎膜后的出血状况,在先兆流产保胎治疗过程中具有重要的临床指导意义。
Objective To investigate the diagnostic value of prenatal ultrasound in the hemorrhage of threatened abortion, and to further analyze the guiding significance of prenatal ultrasound in pregnancy outcome after tocolytic treatment. Methods A total of 120 patients with early pregnancy bleeding in our hospital from December 2013 to December 2014 were selected as the experimental group. Forty pregnant women of the same period were selected as the control group, and the control group (ALOKA 4000) MHz frequency ultrasonic examination to observe the bleeding after the early gestational membranes in patients with and analyze the effect of tocolytic treatment. Results In the control group, no diagnosis of threatened abortion occurred after ultrasound diagnosis. 95 cases of experimental group were diagnosed as threatened abortion, the detection rate was 79.2%. In 69 cases (72.6%) diagnosed by ultrasonography, dark areas were observed, of which 36 (52.2%) were mild and 33 (47.8%) were severe. The patients with clinical miscarriage treatment, the success rate of mild disease treatment was 80.6%, the successful treatment of critically ill patients was 39.4%, mild and severe cases of miscarriage success rate, the difference was statistically significant (χ ~ 2 = 15.280 , P = 0.001). Conclusions Prenatal ultrasound can effectively detect the bleeding after early pregnancy, which plays an important clinical significance in the treatment of threatened abortion.
