Ectopic pregnancies, also known as ectopic pregnancies, are treated conservatively with medications such as methotrexate, which usually requires 1-2 weeks of post-medication observation to achieve a definitive outcome. Ectopic pregnancy is a common cause of acute abdomen in obstetrics and gynecology and has a high mortality rate. Treatment of ectopic pregnancy includes surgery, medication and expectant treatment. Among the pharmacologic treatments methotrexate is currently the main drug used in the conservative treatment of ectopic pregnancy, and its efficacy is exact. Usually, it takes 1-2 weeks of medication to get a more definite effect. The specific efficacy of the drug needs to be based on the blood chorionic gonadotropin β-HCG, blood routine, ultrasound and other imaging results of comprehensive judgment. When the abdominal pain and lower abdominal discomfort disappears, blood chorionic gonadotropin decreases by 30%-50%, the lesions begin to shrink or disappear, and the gestational sac also shrinks or even disappears, the treatment is effective. It should be noted that if the symptoms worsen or there is enlargement of the mass, etc., it suggests that the effect is not good and may require intervention such as surgery; the appearance of ectopic pregnancy should be consulted promptly.
