After 4 days of treatment, the discomfort disappeared, the HCG value dropped significantly and the body improved, so she was discharged from the hospital. The treatment cycle: 4 days of hospitalization, 3 days after discharge for re-examination. Ms. Zhao complained that she was found to be pregnant at the external hospital, but no pregnancy sac was seen on ultrasound, and she requested a follow-up examination. During the consultation, we learned that Ms. Zhao had normal menstrual pattern and no history of dysmenorrhea, her last menstrual period was on April 19, and she had no early pregnancy reaction such as morning sickness and vomiting, and she tested positive for early pregnancy during menopause without any special discomfort. After examination of Ms. Zhao, blood sampling and ultrasound examination, it was found that Ms. Zhao’s HCG value reached 1153.8 mIU/mL (↑) and there was an uneven mass in the right ovary. (Ultrasound) After admission, we completed relevant examinations, including: physical examination, liver function, kidney function, blood routine, urine routine, ECG, HCG test, ultrasound, etc., which were consistent with the characteristics of ectopic pregnancy, so we communicated with Ms. Zhao and her family about the situation. Combined with her age and physical condition, she was treated with methotrexate tablets and told her family that the use of medication would not affect her future fertility and that the risk was small. After 4 days of hospitalization, the HCG value dropped to 121.1mIU/mL, no vaginal bleeding and abdominal pain, and her body condition had improved significantly. （After 4 days of inpatient medication, the efficacy of the medication was obvious, and the HCG value decreased from 1153.8mIU/mL (↑) to 121.1mIU/mL in the follow-up HCG and ultrasound examination. Before discharge, Ms. Zhao was asked to observe at home to see if there were any uncomfortable symptoms such as vaginal bleeding and abdominal pain, etc. Three days after discharge, she returned to the hospital for a review and found that the uncomfortable symptoms disappeared, the HCG value dropped significantly, and her body improved. The patient and her family were very satisfied with the treatment. We are glad that after the medication, Ms. Zhao’s ectopic pregnancy was solved and will not affect conception again. After discharge from the hospital, she can lead a normal life, but the mass in the adnexal area under the ultrasound has not been completely absorbed, so she should avoid strenuous exercise and strenuous sexual life to avoid rupture of the mass. Due to the treatment with methotrexate tablets, it is important to pay attention to common side effects, such as digestive side effects. If nausea, vomiting, abdominal distension, etc. occur, promptly seek medical follow-up and let the doctor determine whether the dosage of medication needs to be adjusted. There are no special requirements for diet after tubal pregnancy treatment, but a light, easily digestible diet is recommended due to possible gastrointestinal side effects. In daily life, pay attention to rest and avoid overexertion. V. Personal insight 1. A woman can clarify whether she has an intrauterine pregnancy by ultrasound examination as early as 5-6 weeks after menopause. If no gestational sac is seen in the uterus, the possibility of ectopic pregnancy should be considered, and if there is pain and/or bleeding in the adnexal area on one side, the possibility of ectopic pregnancy should be considered, which needs to be judged by ultrasound examination in time. If intrauterine pregnancy is not diagnosed by ultrasound, but vaginal bleeding, abdominal pain and other uncomfortable phenomena are found, you should go to the hospital immediately to avoid missing the diagnosis of ectopic pregnancy and delaying the treatment; 2. The integrity of the fallopian tubes can be maintained, especially for women with future fertility requirements, as in the case of Ms. Zhao. But to achieve early detection and early treatment, only as soon as possible to control the disease, in order to reduce physical harm, so as to protect their health; 3, to avoid the emergence of ectopic pregnancy, the first thing to do is to develop good sexual hygiene, habits, such as good personal hygiene before and after sex, to reduce inflammation of the reproductive system and reduce the occurrence of ectopic pregnancy. Secondly, do a good job of contraception to avoid unwanted pregnancies and multiple abortions that cause damage to the endometrium, and finally, regular gynecological examinations to detect problems for timely treatment.
