结局指标
主要结局
blood loss (ml)
时间窗: up to 5-10 minutes
It always takes 5-10 minutes to finish the induced abortion in the outpatient, so the investigators will measure the blood loss during the operation time.
the rate of induced abortion syndrome (%);
时间窗: up to 5-10 minutes
It always takes 5-10 minutes to finish the induced abortion in the outpatient, so the investigators will observe whether induced abortion syndrome happens to our patients during the operation time.
次要结局

- operation time (minutes)(up to 5-10 minutes until the operation finished)
- evaluate pain grade (0, I, II, III) by questionnaire(up to 5-10 minutes)
- the success rate of induced abortion (%)(up to 15 days after the surgery)
