Introduction to vacuum aspiration abortion

Artificial abortion is a common practice. This practice will not have much impact on women's bodies. However, when choosing such an abortion, you need to first understand it so that women can use it with confidence. Vacuum suction abortion is relatively simple and has many indications. The following is a detailed introduction so that you can have more understanding of it.

Vacuum aspiration abortion:

[Indications]

1. Pregnancy is less than 10 weeks and requires termination of pregnancy without contraindications.

2. Those who are not suitable to continue pregnancy due to certain diseases.

[Contraindications]

1. Acute inflammation of reproductive organs, such as pelvic inflammatory disease, trichomonas vaginitis, fungal vaginitis, acute cervical inflammation (surgery is allowed only after treatment)

technique).

2. Patients with acute infectious diseases at any stage or acute attacks of chronic infectious diseases, or severe systemic diseases such as heart failure, blood diseases, etc. (patients need to be hospitalized and undergo surgery after treatment and recovery).

3. Hyperemesis gravidarum acidosis requires treatment followed by surgery.

4. Those whose body temperature is above 37.5t twice with an interval of 4 hours before the operation.

[Preoperative examination]

1. Medical history inquiry? Including amenorrhea, early pregnancy reactions and past menstrual history, marital history and contraceptive measures, past medical history and current health status, etc.

2. General physical and gynecological examination? Routine leucorrhea test, urine pregnancy test, blood pressure and body temperature measurement, B-ultrasound examination of the uterus and gestational sac size. If necessary, blood and urine routine tests, liver and kidney function tests, chest X-ray and electrocardiogram tests were performed.

[Uterine aspiration procedure]

1. The patient empties his bladder and assumes the lithotomy position.

2. Perform routine disinfection of the vulva and vagina before surgery.

3. Use the cervical clamp to clamp the center of the front lip, and use your left hand to pull the cervical clamp outward and fix the uterus.

4. Hold the uterine probe in brush-like position in the right hand and gradually enter the uterine cavity along the direction of the uterus to detect the direction and measure the preoperative depth of the uterine cavity. (Note: Check whether it is consistent with the vaginal bimanual examination. If in doubt, repeat the bimanual examination again to consider whether there is any reproductive tract malformation or possible ovarian tumor).

5. Hold the cervical dilator like a brush in your right hand and probe into the uterus from No. 41/2 to No. 6, 7 or 8 gradually.

6. Connect the suction tip to the rubber tube, and connect the other end of the rubber tube to the negative pressure suction device. Gently insert the suction tip into the uterine cavity until the uterine fundus, then withdraw the suction tip a little, use the foot-operated suction switch, the suction force of the negative pressure gauge should be between 400 and 500 mm, the suction tip will rotate in the uterine cavity to find the implantation site of the fertilized egg. Generally, the fertilized egg implants are mostly in the anterior and posterior walls of the uterine fundus. When the fertilized egg is found, gently rotate the suction head at that location and pump it up and down to suck out all the tissue. Then rotate it around the cavity to suck it out once. You can feel the cavity gradually shrinking and the uterine wall sticking close to the suction head, indicating that the placental tissue has been sucked out. At this time, pinch the rubber tube first and then remove the suction head. Be careful not to bring negative pressure in and out of the cervical tube.

7. If there is embryonic tissue stuck in the mouth of the straw when you pull out the straw, you can use oval forceps to remove the tissue.

8. Use a curette to scrape the uterine wall around and check whether it is clean. If it is clean, you will feel the wall is rough around it. If a certain part of the wall feels slippery, it means it is not clean, then put the suction head into the cavity to clean the tissue there.

9. Measure the depth of the uterine cavity again, remove the cervical forceps, and use gauze forceps to wipe off the blood in the cervix and vagina. If there is active bleeding, use gauze to compress and stop the bleeding. Remove the vaginal dilator, filter the sucked out tissue with a filter, measure the amount of bleeding and tissue, and carefully check whether there are villi in the tissue and how many villi there are. If the tissue is not fresh and is accompanied by old blood clots, antibiotics will be given to prevent infection. If abnormalities are found and no villi are seen, all tissues should be sent for pathological examination.

After understanding the negative pressure abortion technique, women should actively cooperate with the doctor when undergoing such an abortion. Also, women should be careful not to be too nervous, as emotional tension is not good for the body. This is something to keep in mind.
