What are the advantages and disadvantages of Sheung Wan? Please, great gods.

"Ring" is the most commonly used long-term contraceptive measure for women of childbearing age in China, and often a ring can be placed in the body for more than ten years. But how many women can understand this "ring" left in their bodies all the year round, and how many women have chosen the type that really suits them? 1. How many "rings" are called intrauterine devices, which are placed in the uterus of women of childbearing age to achieve contraceptive purposes through mechanical stimulation and chemical interference, without inhibiting ovulation and affecting women's endocrine system, thus avoiding the adverse reactions of general contraceptive drugs. After years of practice and improvement, most of the intrauterine devices currently used in clinic are copper-containing or drug-containing intrauterine devices, and the stent materials are plastic, polyethylene, memory alloy and so on. And their shapes are not single, such as round, T-shaped, V-shaped, Y-shaped, chain-shaped and so on. Different materials and shapes of intrauterine devices have their own characteristics, which can be applied to women with different constitutions and needs. 2. The correct time to place the IUD. Women who place IUD for the first time especially want to know when it is best to place IUD. In fact, at present, apart from the contraindications of IUD release, there are few restrictions on the release time of IUD. After a lot of practice and scientific appraisal, scientific and technical personnel believe that it is safe and feasible to place intrauterine devices in the following periods: (1), when menstruation is unclean. On the 3rd-5th day of menstrual cramps, there are three advantages during this period: First, the cervix is loose and easy to put in. Second, when menstruation has just arrived, pregnancy can be ruled out and the ring will not be placed in the pregnant uterus by mistake. Third, it avoids the worry and inconvenience caused by a small amount of bleeding after releasing the ring. (2), placed after menstruation is clean. It is advisable to ring the ring 3-7 days after menstruation is clean and there is no sexual history, because the endometrium has just begun to grow and is thin at this time, so bleeding can be avoided when placed, and there is no sexual life after menstruation, which also avoids the possibility that fertilized eggs have grown on the endometrium when ring it. Generally, most women will choose to release the ring at this time. (3) Release the ring immediately after delivery. At this time, the operation is simple and easy, and contraceptive measures can be implemented in time, but it can only be placed after approval by obstetricians. (4) Placed 42 days after delivery. That is, about 42 days after delivery, it should be placed at the same time as health examination. The advantages of placing at this time are: first, cervical relaxation. Second, the uterus has returned to normal size and has not shrunk due to long-term breastfeeding. Third, contraceptive measures were implemented in time, which facilitated women and avoided the occurrence of "hidden fetus". (5) It can be released more than three months after delivery. However, it should be noted that if this time is lactation, although there is no menstruation, there is still the possibility of pregnancy, which is what people usually call a "dark fetus." Therefore, women who haven't menstruated after delivery should first check with a doctor to see if they are pregnant, and they can be released if they are not pregnant. (6) Curettage immediately after induced abortion or operation. The advantage is that contraceptive measures are implemented at the same time in one operation, which reduces the pain and is convenient for women. (7) Curettage after spontaneous abortion or induced abortion returns to normal menstruation. (8), caesarean section at the same time or surgery for half a year, the situation is normal, you can also consider releasing the ring. (9) If the previously placed ring has expired and needs to be replaced, a new ring can be put in while removing the ring. You can also put in a new ring after the next menstrual period is clean. But you must remember to pay attention to contraception this month after taking the ring. 3. For people who are not suitable for placing intrauterine devices, lifelong self-observation and health care are very important, and there are many contents of self-care. So what do you need to pay attention to after placing intrauterine devices? How to deal with specific problems correctly? (1), take a proper rest and avoid excessive physical labor. Generally, you should rest for 1-2 days after releasing the ring, and don't do heavy physical labor within one week, so as not to cause bleeding when the ring falls off. (2) Pay attention to hygiene and avoid infection. After putting on the ring, the vulva should be cleaned every day and kept clean. Don't take a bath in a basin for 2 weeks, and don't share the same room for 2 weeks to avoid infection. (3) Pay attention to vaginal bleeding and ring shedding. If vaginal bleeding is found, the menstrual flow is more than twice as much as usual or the bleeding time is long, and the menstrual cycle changes obviously, you should go to the hospital for examination. In the first three months, always pay attention to whether the ring has fallen off. (4), regular inspection. Generally, the first check-up after IUD is after the first menstruation, the second check-up is within 3-6 months after IUD, and the third check-up is after 12 months, and then it is checked once a year. (5) Possible side effects after releasing the ring. If the menstrual flow increases obviously after releasing the ring, the menstrual period is obviously prolonged or there is often a small amount of bleeding and severe backache and abdominal pain, these are abnormal phenomena, and you should go to the hospital for examination. (6) Pay attention to supplementary nutrition. Pay attention to diet and nutrition after placing IUD, especially eat foods rich in iron, such as lean meat, pork liver, pork loin and eggs. You can also eat more soy products and increase vegetables and fresh fruits. Generally, after the above diet and conditioning, you can effectively prevent the physical exertion caused by the side effects after releasing the ring. 5. After the IUD is released, several cases are handled as minor operations, and foreign bodies need to be placed in the uterine cavity. The reaction of uterus to foreign body is to try to squeeze out foreign body by strengthening contraction. Most people don't feel uterine contraction and can adapt, but some people feel low back pain, back pain, a little vaginal bleeding and other conditions. How to deal with them? (1) Mild low back pain, backache, but uncomfortable after releasing the ring. The uterus contracts and will disappear naturally after a period of time. Be careful not to do heavy work during this time. (2) A small amount of vaginal bleeding, or shortened menstrual cycle, more menstrual flow and prolonged menstrual period, is due to the oppression of endometrium by the ring and inflammatory infiltration of cells. As time goes on, the symptoms will disappear after the uterus adapts. (3) Increased leucorrhea: When the uterus is stimulated, the cervical secretion will increase, and this symptom will gradually decrease after placing the intrauterine device for 3 months. 6. What are the reasons for the ring falling off? After being put into the uterine cavity of a woman, for some reason, it will sneak out of the uterus, which is what people call ring shedding. Some people can find out in time when their rings are lost, while others don't know at all. They didn't know until they were pregnant or had a follow-up examination. Many people are worried. So what caused the ring to fall off? How can we effectively prevent it? There are several factors that cause the ring to fall off: (1), and the loose cervix is the main reason for the ring to fall off. (2) The uterus contracts, so that the ring slowly descends until it is excreted. (3) The size and type of the ring are inconsistent with the uterine cavity, which leads to uterine contraction and the ring is discharged from the body. (4) The position of the ring in the uterine cavity is incorrect. As soon as the uterus contracts during menstruation, the ring is easy to fall off. (5) The quality and type of the ring are also related to the shedding of the ring. Previously used soft rings such as metal single rings are easy to fall off. After the ring falls off, you should consult a doctor in time. As long as we know the reason of the ring falling off, with the cooperation of Qi Xin, the medical staff, we can definitely reduce the occurrence of the ring falling off. 7. What about long-term menorrhagia after releasing the ring? What should I do? Take the medicine first. The correct medication should be ibuprofen, naproxen and indomethacin. These drugs inhibit the synthesis of prostaglandin, and the reduction of prostaglandin can effectively reduce uterine bleeding. In addition, anti-fibrinolytic drugs such as 6- aminoacetic acid and Zhixuemin will not strengthen uterine contraction, and the effect is also good. In addition, Yunnan Baiyao has the effects of promoting blood circulation to stop bleeding, removing putrefaction and promoting regeneration, and the effect is also good. If the effect of taking medicine is not good, it is necessary to consider that the shape of uterus may not adapt to the size of intrauterine device, and a ring can be changed if necessary. After the ring is changed, the ring will not be pressed in the same place all the time, and the damaged endometrium will heal naturally. It's not enough. Other contraceptive methods can be used. 8. Why is someone pregnant with a ring? How to avoid it? Placement of IUD is an ideal contraceptive method with an effective rate of over 90%. However, a few women are still pregnant after placement for the following reasons: (1). The IUD fell off, but I didn't notice it. This is the most common reason for contraceptive failure. (2) The IUD placed in the low position near the cervix can not inhibit the implantation and development of fertilized eggs. (3) The size of the IUD does not match the size of the uterine cavity, or the IUD has been deformed or even broken, losing its contraceptive effect. In order to avoid the above situation and reduce intrauterine pregnancy, we should go to the hospital regularly for examination, once within 3 months after placement, and then review once a year. Pay special attention to whether the IUD pops up during the inspection. Once the IUD pops up, take timely measures to make up or replace other contraceptive measures. Women who have had IUD falling off and pregnant with IUD should strengthen their examination after re-placement. 9. Do you need to check regularly after wearing the IUD? Routine examination should be done after the first menstrual cramp. If there are no special problems, you can check it regularly once a year. 10. With the advent of menopause, the estrogen secreted by ovaries drops rapidly and the uterus shrinks gradually. After menopause, the uterine cavity shrinks day by day, and the uterine muscles become thinner and thinner. After a long time, the ring will be partially or completely embedded in the superficial muscle layer of the uterus, and it is difficult to take out the ring. If there are blood vessels in the embedded part of the ring, it will cause bleeding. If the ring is embedded too deeply and even swims into the abdominal cavity through the thin uterine wall, a series of complications may occur, so it is very important to take out the ring in time. The ring must be removed in the following cases: (1). The ring has reached the specified age and should be taken out of the hospital in time to avoid deformation or failure of the ring in the uterus. General metal rings can be stored for 20 years, silicone rubber V-rings can be stored for 7- 10 years, copper sleeve T-rings can be stored for 10- 15 years, and new rings can be put in when taking the rings. (2) If there are any adverse reactions affecting health such as irregular vaginal bleeding or persistent menorrhagia after placing the IUD, take out the IUD in time if drug treatment has no effect. (3) The menstrual cycle of menopause has changed obviously. If the cycle becomes longer or menopause lasts for more than 6 months, the ring should be removed in time. Before taking out the ring, X-ray fluoroscopy or "B" ultrasonic inspection should be carried out. For the ring with tail wire, please ask the doctor to open the vaginal opening to see if there is nylon wire outside the uterine orifice to confirm that the ring is in the uterine cavity, and then take out the ring. The best time to take the ring is within 3-7 days after menstruation is clean, which can reduce bleeding. Take a rest 1 day after removing the ring, and forbid sexual life and bath for 2 weeks to prevent infection. There may be a small amount of bleeding or bloody leucorrhea in the vagina after the removal of the ring, which will disappear naturally after a day or two. This is a normal phenomenon, which is caused by taking the ring to stimulate the endometrium and cervix. If there is more bleeding or bleeding for a long time, you should seek medical advice in time. 1 1. How long can I get pregnant after taking the ring? Generally, it is better to start pregnancy after two or three normal menstruation, so that the endometrium can have a recovery time.
