The surgical process of negative pressure aspiration for abortion

Artificial abortion refers to the termination of pregnancy by surgical methods within 3 months of pregnancy, including vacuum aspiration and forceps curettage. Vacuum aspiration is suitable for those who want to terminate pregnancy within 10 weeks of pregnancy without contraindications; for those who are not suitable for continuing pregnancy due to certain diseases within 10 weeks of pregnancy, the surgical process includes the following:

1. Body position and disinfection

After emptying the bladder, the woman takes the lithotomy position. After routine disinfection and laying a drape, the position, size, curvature and adnexa of the uterus are reviewed by bimanual examination. The cervix is ​​exposed and disinfected with a vaginal speculum.

2. Detection of the uterine cavity

The cervical forceps clamp the anterior lip of the cervix, and the uterine probe is used to detect the flexion and depth of the uterus along the direction of the uterus.

3. Dilate the cervix

The cervix is ​​dilated with a cervical dilator from small to large. For patients who are nervous or sensitive to pain, cervical mucosal anesthetics, paracervical block anesthesia or intravenous anesthesia should be used before cervical dilation.

4. Straw suction

Before suction, conduct a negative pressure suction test. After confirming that it is correct, select the thickness of the suction tube and the size of the negative pressure according to the gestational age. Generally, the uterine cavity is suctioned in a clockwise direction for 1 to 2 weeks to suck out the pregnancy.

5. Check whether the uterus is completely clean

Use a small curette to gently scrape the uterine cavity, paying special attention to the uterine fundus and the uterine corners on both sides to prevent incomplete uterine suction. Check whether the aspirated material contains villi or embryonic tissue, and whether it is consistent with the month of pregnancy. If any abnormality is found, it should be sent for pathological examination in time.
