Painless abortion

　　Pregnancy is a natural physiological phenomenon, and painless abortion is a method of artificial abortion after pregnancy. It is mainly used as a remedial measure for unintended pregnancy due to contraceptive failure, and also for those who need to terminate pregnancy due to illness, to prevent congenital malformations or hereditary diseases. It is mainly used for those who wish to terminate pregnancy within 10 weeks of pregnancy without contraindications, or for those who are not suitable for continuing pregnancy due to certain diseases or hereditary diseases. The painless abortion operation not only relieves the physical pain of the patient, but also greatly alleviates the fear of the subject.

      Painless abortion surgery refers to the artificial termination of pregnancy performed by gynecologists under general anesthesia administered by an anesthesiologist. It is based on the suction dilatation and curettage operation, supplemented by intravenous general anesthesia, without pain during the operation. The main complications of painless abortion include the following aspects:

　　1, Blindly injure the uterus

　　Painless abortion surgery relies solely on the experience and sense of clinical doctors to complete. Due to the inability to understand the specific situation inside the uterine cavity, there is a risk of improper operation leading to uterine perforation, massive bleeding, and other conditions, especially for women with uterine malposition or malformed uterus, which is more likely to occur. Some women who have had repeated dilatation and curettage are prone to miscarriage, and even lead to lifelong infertility.

　　2, Operation infection

　　According to the data published by the National Health and Family Planning Commission in 2009, 42% of secondary infertility patients in China are caused by repeated abortion infections. Poor operating environment, unstrict sterilization of instruments, improper operation, and other factors may lead to infection and subsequent inflammation such as cervicitis and pelvic inflammation. If the inflammation is not treated for a long time, pathogenic bacteria can ascend and infect, easily causing other reproductive system diseases, and may also lead to tubal obstruction infertility.

　　3, Lead to infertility

　　During painless abortion, many complications may occur, the most life-threatening of which is cardiovascular syndrome. In addition, there are complications such as bleeding, injury, cervical adhesion, pelvic inflammation, etc. The greatest harm of repeated abortions is that the chance of uterine injury increases, and the injury to the endometrium directly affects the future fertility, and severe cases may lead to infertility.

　　4, Decreased menstrual blood volume

　　After painless abortion, the amount of menstrual blood may decrease, and the amount of menstrual blood is a direct reflection of the uterine endometrial condition. A decrease in amount means that the endometrium is damaged. Abortion can damage the endometrial base, and it is easy to have implantation in the future pregnancy, that is, the fertilized egg implants and grows downward like a root, and it is not easy to clean during the second abortion, and it is necessary to perform a second dilatation and curettage. In addition, complications such as inflammation may lead to infertility and ectopic pregnancy; generally, menstruation will return after one month after painless abortion.

　　After the placenta is stripped during painless abortion, there may be some bleeding from the incision left on the uterine wall. This condition usually stops gradually with uterine contraction and wound repair, usually within 3-5 days, and the vaginal bleeding does not exceed 10-15 days at most. If the amount of vaginal bleeding exceeds the menstrual blood volume, it is necessary to seek medical treatment in a timely manner. The main symptoms of painless abortion are slight vaginal bleeding or irregular bleeding.

　　The main preventive measures for painless abortion are to prevent unintended pregnancy and to conduct pre-pregnancy examinations. Painless abortion has the advantages of rapid onset of analgesia, good effect, high efficiency, safety, reliability, and few side effects, which solves the physical pain and psychological fear of patients, and has become an effective, safe, and easily accepted surgical method for artificial termination of pregnancy. The main preventive measures for painless abortion are to prevent unintended pregnancy and abortion. It is a remedial measure for women after contraceptive failure and should never be used as a means of contraception because of the reduced pain.

       Before the painless abortion surgery, the doctor must inquire about the medical history in detail. Those with a history of heart, lung, liver, and kidney diseases must inform the doctor. The following preoperative examinations should be conducted, and the doctor will judge whether it is suitable for painless abortion surgery.

　　1. Ultrasound examination

　　General ultrasound examination can determine the size of the fetal sac to avoid incomplete abortion. At the same time, ultrasound examination can also exclude the risk of ectopic pregnancy. It is not allowed for women to have gynecological inflammation during the abortion surgery, so it is necessary to conduct inflammation checks before the operation to understand whether the patient has gynecological inflammation. If gynecological inflammation is found, it should be treated in a timely manner to avoid postoperative complications and sequelae.

　　2. Early pregnancy test strip detection

　　When women find that they have missed their period, they should first consider whether they are pregnant. They can use early pregnancy test strips for detection. If two red lines appear, it indicates that the woman is pregnant. To ensure the accuracy of the test, it is recommended that women go to a regular hospital for urine HCG or blood HCG tests.

　　3. Vaginal secretion detection

　　This examination is mainly to understand whether there are trichomonas or mold in the vagina of the patient. If these pathogens are present, treatment should be given in a timely manner to prevent ascending infection and affect the effect of the abortion surgery.

　　Due to the weakened physical condition of women after painless abortion, they often sweat a lot. It is necessary to supplement more water, but it should be done in small amounts and frequently to reduce the amount of water evaporation. Sweat contains a large amount of water-soluble vitamins, especially vitamin C, vitamin B1, and vitamin B2, so it is recommended to eat more fresh vegetables and fruits. This also helps prevent constipation.

　　Ensure the supply of high-quality protein, adequate vitamins and inorganic salts, especially sufficient iron to prevent anemia. Food selection should not only be nutritious but also easy to digest and absorb. Fresh fish, tender chicken, eggs, animal liver, animal blood, lean meat, soy products, milk, jujube, lotus seeds, fresh fruits, and vegetables can be provided.

　　It is necessary to appropriately limit fat on the basis of normal diet. Within a week after the operation, fat should be controlled at about 80 grams per day. For those with menstrual irregularities, avoid spicy foods such as chili, alcohol, vinegar, pepper, ginger, etc., as these foods can cause congestion of the organs and increase the amount of menstruation. Also, avoid cold foods such as crabs, snails, and clams.

      The painless abortion surgery has the advantages of fast analgesic onset, good effect, high efficiency, safety, reliability, and few side effects. It alleviates the physical pain and psychological fear of patients, and has become an effective, safe, and easily acceptable surgical method for artificial termination of pregnancy.

　　1. General painless abortion: Safe, painless, quick recovery, no sequelae, early termination of pregnancy before 6 weeks. Suitable for early pregnancy, young women who have not given birth, or women with strong early pregnancy reactions who urgently need to terminate pregnancy.

　　2. Ultrasonic guided painless abortion: Combining advanced B-ultrasound, the painless abortion technique is brought to its peak, completed in a 1000-layer clean operating room. The positioning is accurate, without discomfort, and completely avoids postoperative infection.

　　3. Ultrasonic guided (minimally invasive) painless abortion: Utilizing direct vision endoscopy combined with effective medicine, the patient completes the operation in a dream. The operation is accurate, thorough, painless, does not damage the uterus, safe with no side effects, and can leave immediately after treatment.

　　4. Micro-tube visual painless abortion: So-called 'micro-tube visual painless abortion' refers to using a soft micro-tube under the guidance of high-tech endoscopy, with the 'eye of a thousand miles' through the needle hole, directly and easily reaching the gestational sac. Without dilating the cervix, the gestational sac inside the body is suctioned out. The entire operation takes only three minutes. No hospitalization is required, and you can walk at any time.

　　5. Uterine cavity aspiration technique: Whether it is a young girl or a married woman, relevant examinations should be conducted before the abortion operation to determine the appropriate method for herself. The technique with the least harm to the body is the uterine cavity aspiration technique. This type of technology combines the three major advantages of painless technology, micro-tube technology, and uterine cavity visualization operation. Under the visualization system, the doctor can accurately and clearly see the position of the gestational sac and accurately attract it using a disposable soft tube, thus avoiding injury to other normal tissues.

　　6. Double-channel decompression painless abortion: The double-channel decompression painless abortion technique combines the dual advantages of visual painless abortion and double-channel decompression suction tube, and is a green new generation of uterine cavity suction technology. The double-channel decompression suction tube is designed according to the principle of biological fluid mechanics and is a high-tech surgical instrument developed to address the shortcomings of traditional suction tubes. It adds a secondary tube to the original structure of the traditional suction tube, where the main tube attracts embryo tissue, and the secondary tube utilizes the pressure difference between the uterine cavity and the atmosphere to discharge fluid outward, thereby reducing the uterine cavity pressure during suction to prevent reverse flow of uterine blood.
