目的探讨阴道超声监测孕囊大小及子宫位置与药物流产临床结局的相关性及临床应用价值。方法回顾性分析950例要求药物流产的孕妇,用药前阴道超声检查,服药后8天未排出孕囊为药流失败,服药孕囊自行排出后10天阴道超声复查仍有异常回声组织或阴道出血过多淋漓不净最终清宫者为药流失败。结果子宫位置中,后倾后屈位者药流失败率明显高于其他位置;孕囊<8mm组及>25mm组药物流产失败率高有显著差异(P<0.05)。结论阴道超声监测具有方便准确的优点,可监测药物流产效果,并指导临床处理。
Objective To investigate the correlation between vaginal ultrasound for gestational sac size and uterine position and the clinical outcome of medical abortion and its clinical value. Methods A retrospective analysis of 950 pregnant women who required medical abortion was performed. Vaginal ultrasonography was performed before treatment and the gestational sac was not discharged for 8 days after the medication. The vaginal ultrasound examination still had abnormal echogenic tissue or vaginal bleeding 10 days after the administration of gestational sac Mostly Purified Purify the ultimate Purge for medical abortion. Results In uterine position, the failure rate of backward flow and backward flexion was significantly higher than that of other positions. There was a significant difference (P <0.05) in failure rate of medical abortion between gestational sac <8mm group and> 25mm group. Conclusion Vaginal ultrasound monitoring has the advantages of convenience and accuracy, can monitor the effect of medical abortion, and guide the clinical treatment.
