Nghiên cứu kết quả điều trị ngoại trú chửa ngoài tử cung chưa vỡ bằng Methotrexate liều đơn tại Bệnh viện Phụ Sản Hà Nội

To evaluate the effectiveness of medical treatment of unruptured ectopic pregnancy with single dose Methotrexate (MTX). Study Design and Methods: A cross-sectional descriptive study was conducted on 98 patients diagnosed with unruptured ectopic pregnancies treated with a single dose of MTX at the gynecology outpatient clinic of Hanoi Obstetrics Hospital from July 2021 to June 2022. Results: The average age of the study participants was 39.5 ± 4.2, with 48% nulliparous patients and 61.2% having a history of curettage or miscarriage. The highest treatment success rate was observed in patients with initial βhCG levels below 500mIU/ml and ectopic mass size smaller than 20mm. Initial βhCG levels and smaller ectopic mass size were associated with higher success rates, and this difference was statistically significant with p < 0.05. Adverse effects were observed in 32.65% of patients, mostly mild and not requiring treatment. Conclusion: Lower initial βhCG levels and smaller ectopic mass size are associated with higher success rates in the treatment of unruptured ectopic pregnancies with MTX
