What is abortion syndrome

During abortion operations, a small number of women experience nausea, vomiting, dizziness, chest tightness, shortness of breath, pale complexion, profuse sweating, cold limbs, low blood pressure, irregular heartbeat, etc. In severe cases, they may also experience a series of symptoms such as fainting, convulsions, and shock, which is called "abortion syndrome."

Abortion syndrome is a series of vagus nerve excitement symptoms caused by excessive local stimulation during abortion suction or curettage. Most pregnant women can tolerate these mechanical stimulations during abortion through the self-regulation of the nervous system, but a few pregnant women have poor autonomic nerve stability, which enhances the vagus nerve's own reflexes, releases a large amount of acetylcholine in the body, promotes coronary artery spasm, weakens myocardial contractility, and reduces cardiac output, resulting in the above series of manifestations. At this time, after proper treatment, it will not pose a threat to the patient and will not leave sequelae.
