Preoperative examination for suction abortion

Surgery is a common method for treating diseases. You can rest assured to choose surgery for this purpose. However, when performing surgery to treat diseases, you should also pay attention to the methods used. You cannot choose it casually. You should first understand the surgical treatment methods so that you can have some understanding of whether it is helpful for the treatment of the disease. So what are the preoperative preparations for suction abortion? The following is a detailed introduction.

Preoperative examination for suction abortion:

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

2. General physical examination 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.

How to operate

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

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

3. Use a 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 with a size of 4 l/2, and gradually expand it to size 6, 7 or 8.

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 is 400-500mm, the suction tip rotates in the uterine cavity to find the implantation site of the fertilized egg. Generally, the fertilized egg implants more often on 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 scraper to scrape the uterine wall around to check whether it is clean. If it is clean, you will feel the roughness around the wall. 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 preoperative preparations for suction abortion, when performing suction abortion, you should follow the above methods. In addition, your emotions should be adjusted before the operation. Unstable emotions will also affect the suction abortion. Patients should pay attention to this when performing suction abortion.
