阴道B超协助选择药流最佳时机

Selection of the best opportunity of drug abortion by vaginal B-mode ultrasound assistance

目的:选择药流最佳时机。方法:通过阴道B超测定妊娠49天内的孕囊大小,监测其药流后的完全流产率,不全流产率,失败率,流血时间,流血量,不良反应,探查孕囊大小与药流的出血时间、出血量、及完全流产率等的关系,从而选择药流最佳时机。结果:孕囊大小与药流的出血时间、出血量成正比关系;孕囊大小与完全流产率成反比关系。结论:阴道B超可以测定比腹部B超更早更小的孕囊,可以帮助选择药流最佳时机。

Objectives：To study the best opportunity of drug abortion.Methods：To measure the size of aged 49-day gestation sac before conducting drug abortion by vaginal B-mode ultrasonography,monitor the details of their complete abortion rate,incomplete abortion rate,failure rate bleeding time,bleeding volume and side effects and investigate the correlations between the size of gestation sac and bleeding time,bleeding volume,complete abortion rate etc after conducting drug abortion,so as to find out the best opportunity of drug abortion.Results：There is a direct ratio relation between the size of gestation sac and the bleeding time,bleeding volume of drug abortion, and meantime a inverse ratio relation between the size of gestation sac and the complete abortion rate.Concluslon：By vaginal B-mode ultrasonography,the earlier and smaller gestation sac can be measured than by abdominal B-mode ultraonography,and it can help to select the best opportunity of drug abortion.
