The use of assisted reproductive technologies (ART) has increased steadily. There has been a corresponding increase in the number of ART-related procedures such as hysterosalpingography (HSG), saline infusion sonography (SIS), hysteroscopy, laparoscopy, oocyte retrieval, and embryo transfer (ET). While performing these procedures, the abdomen, upper vagina, and endocervix are breached, leading to the possibility of seeding pelvic structures with microorganisms. Antibiotic prophylaxis is therefore important to prevent or treat any procedure-related infections. After careful review of the published literature, it is evident that routine antibiotic prophylaxis is generally not recommended for the majority of ART-related procedures. For transcervical procedures such as HSG, SIS, hysteroscopy, ET, and chromotubation, patients at risk for pelvic infections should be screened and treated prior to the procedure. Patients with a history of pelvic inflammatory disease (PID) or dilated fallopian tubes are at high risk for postprocedural infections and should be given antibiotic prophylaxis during procedures such as HSG, SIS, or chromotubation. Antibiotic prophylaxis is recommended prior to oocyte retrieval in patients with a history of endometriosis, PID, ruptured appendicitis, or multiple prior pelvic surgeries.

Abstract This retrospective cohort study investigates the risk factors and beta-human chorionic gonadotropin (β-hCG) trends in patients with ruptured tubal ectopic pregnancies (EPs) despite methotrexate (MTX) treatment. All patients receiving MTX for sonographically confirmed tubal EPs at our fertility center between 2004 and 2014 were included. Baseline demographics and β-hCG trends of patients with EP rupture after MTX were compared to patients with resolved EPs after MTX. One-hundred-thirty-seven patients with EPs were treated with MTX during the study duration; 27 experienced EP rupture and 110 EP resolution. There was no difference in the baseline demographics or β-hCG levels on the day of MTX between the groups. Patients with ruptured EPs after MTX had higher β-hCG levels on day-4 (1223.9 ± 243.5 vs. 1111.2 ± 179.7 mIU/mL; p < .001) and day-7 (1156.9 ± 206.2 vs. 872.4 ± 690.2 mIU/mL; p < .001). The odds of EP rupture compared to EP resolution was 6.2 (95% CI 2.1–19.1), 13.7 (95% CI 4.8–38.9), and 3.0 (95% CI 1.2–7.2) times higher when the change in β-hCG levels was <5% between day-7 vs. day of MTX, day-7 vs. day-4, and day-4 vs. day of MTX, respectively. Our results demonstrate that ruptured tubal EPs despite MTX have <5% change in β-hCG levels between the day of MTX and day-4 or day-7 after MTX.
