Signs of successful conservative treatment of ectopic pregnancy include a decrease in blood HCG level, relief or disappearance of abdominal pain and vaginal bleeding. Ectopic pregnancy refers to ectopic pregnancy. When the diagnosis is clear by ultrasound examination, methotrexate can be given as conservative treatment as prescribed by the doctor when the condition is stabilized, the diameter of the gestational sac is less than 4cm, and the blood HCG (human chorionic gonadotropin) is less than 2000 U/L. When the blood HCG test after treatment decreases and is negative for 3 consecutive times, the abdominal pain is relieved or disappears, and the vaginal bleeding stops, it is a sign of successful cure. When the blood hCG is not obviously decreased after 4-7 days of drug conservative treatment, it is necessary to repeat the treatment as prescribed by the doctor. If there is no obvious improvement after 14 days of treatment, or even acute abdominal pain or symptoms of rupture of the pregnancy site occurs, it is necessary to carry out surgical treatment immediately. During the conservative treatment of ectopic pregnancy, it is necessary to closely monitor the changes in the condition, as well as early detection of abnormalities and active treatment, in order to ensure the safety of life.
