There are several methods of abortion surgery

With the advancement of contemporary medical technology, there are different methods for abortion surgery, mainly including three categories: Curettage is more suitable for pregnancy weeks 10-13. This operation mainly uses a combination of clamps and negative pressure suction to achieve the purpose of terminating pregnancy. Vacuum aspiration is suitable for women who are less than 10 weeks pregnant. This operation is relatively safe and simple. Vacuum aspiration uterine abortion is also known as painless artificial abortion.

Abortion surgery - curettage

Anyone who is between 10 and 13 weeks pregnant and wishes to terminate the pregnancy, or who is not suitable for pregnancy due to special circumstances such as illness or has failed other abortion methods. Generally, a combination of clamping and negative pressure aspiration is used to terminate pregnancy. The scope of clamping is generally recommended to be within 14 weeks. In recent years, due to the clinical application of mifepristone, prostaglandins, etc., clamping and curettage have gradually been replaced by medical induction of labor. The indications for this abortion method are those who are 10 to 13 weeks pregnant and wish to terminate the pregnancy or those who are not suitable for pregnancy due to special circumstances such as illness; and those who have failed other abortion methods. Contraindications include the acute stage of various diseases; inflammation of the reproductive organs, such as vaginitis, acute suppurative cervicitis or subacute cervicitis, acute and chronic pelvic inflammatory disease, sexually transmitted diseases, etc., which can only be treated before surgery; patients with poor general condition who are unable to undergo surgery can consider hospitalization for surgery after improvement after treatment; patients with a body temperature above 37.5℃ twice before surgery.

Vacuum aspiration for abortion surgery

This type of abortion is suitable for uteruses within 10 weeks of pregnancy. The method mainly uses negative pressure electric aspiration to suck out the early pregnancy products, namely the embryonic sac and decidual tissue, which is called artificial abortion negative pressure aspiration or simply negative pressure aspiration. This method was first invented in my country. The operation is relatively safe and simple, and is therefore a commonly used means of terminating early pregnancy in clinical practice. The indications include those who want to terminate the pregnancy within 10 weeks without contraindications; those who are not suitable to continue the pregnancy due to certain diseases or genetic diseases. Contraindications include the acute stages of various diseases, acute myocardial infarction, acute cerebral infarction, acute hepatitis, acute blood system diseases, acute kidney diseases, acute surgical diseases, etc. Patients with untreated inflammation of reproductive organs, such as vaginitis, acute suppurative cervicitis or subacute cervicitis, acute or chronic pelvic inflammatory disease, sexually transmitted diseases, etc.; patients who are unable to assume lithotomy position due to illness or trauma; patients with poor general condition and unable to tolerate surgery; patients with body temperature above 37.5℃ twice before surgery should postpone surgery.

Anesthesia and analgesia techniques for abortion surgery: vacuum aspiration

This is commonly known as painless artificial abortion. The indications for this type of abortion are those who voluntarily request anesthesia and analgesia to terminate the pregnancy within 10 weeks of pregnancy; those who are not suitable to continue the pregnancy due to certain diseases (including genetic diseases) and voluntarily request anesthesia and analgesia to terminate the pregnancy; those who have no contraindications to vacuum aspiration, anesthetics and general anesthesia; and those who meet the American Society of Anesthesiologists (ASA) preoperative assessment standard level I-II.
