Women with ectopic pregnancy are treated conservatively, that is, the embryo is killed with drugs and then absorbed slowly, which usually takes 1-2 weeks in short cases and 3-4 weeks in long cases. When ectopic pregnancy occurs in women, if the ultrasound indicates that the mass is less than 4 cm and the blood HCG is less than 2000 U/L, and the mass has not ruptured and there is no obvious pelvic fluid, conservative treatment with drugs can usually be considered. Conservative treatment of ectopic pregnancy takes a long time, mostly 1-2 weeks. Blood HCG levels are checked on days 4 and 7 of the medication until the blood HCG drops below 5 U/L. If the serum HCG drop is less than 15% on days 4-7 after treatment, the treatment will need to be repeated. For those with higher HCG, the duration of conservative treatment is extended accordingly and may be up to about 1 month. Generally, a decrease in serum 14 days after medication and three consecutive negative results, relief or disappearance of abdominal pain and reduction or disappearance of vaginal bleeding indicate that the conservative treatment is effective. In addition, conservative treatment of ectopic pregnancy may be ineffective for some patients, and should be closely monitored during the treatment process. Once abdominal pain worsens and shock occurs, it indicates the possibility of ectopic pregnancy rupture and requires immediate surgical treatment.
