Negative pressure aspiration is actually what we usually call abortion. It is performed by using a certain type of suction tube to remove the pregnancy sac or other contents from the uterine cavity under negative pressure to terminate the pregnancy. Negative pressure aspiration is usually used for women who are less than 10 weeks pregnant. The procedure has a history of more than 40 years, and is a minimally invasive procedure that takes only 5-10 minutes to perform, making it simple and effective. However, negative pressure aspiration can also have certain side effects, such as causing abdominal pain, heart rhythm disturbance, sweating, pale face, vomiting, chest tightness, dizziness and other symptoms, and if the doctor is inexperienced, improper surgical operation, there may be a series of more serious complications such as uterine bleeding, uterine perforation, cervical laceration. In addition, due to the use of negative pressure suction, it is also easy to make the endometrial tissue enter the abdominal cavity with the backflow of blood after the operation, which may lead to endometriosis, and then female infertility. Although negative pressure suction surgery is a minimally invasive procedure, the damage to the body is inevitable, so you need to strengthen nutrition and pay more attention to rest after surgery. It is necessary to take good care of contraceptive measures and to avoid having this procedure repeatedly.
