Expectant management of tubal pregnancies with human chorionic gonadotropin up to 2000 mIU/mL.

OBJECTIVE: To describe outcomes of expectant management (EM) versus methotrexate (MTX) treatment in tubal pregnancies with pretreatment human chorionic gonadotropin (hCG) less than 2000 mIU/mL. METHODS: This retrospective cohort from two tertiary hospitals included women with confirmed tubal pregnancies and pretreatment hCG <2000 mIU/mL. Exclusion criteria were unrecorded pregnancy site, unconfirmed diagnosis, and surgical treatment upon diagnosis. The primary outcome was eventual rate of surgical treatment. RESULTS: Between December 2009 and June 2021, 545 of 2114 (25.8%) women diagnosed with a tubal pregnancy met our inclusion criteria. We compared women who underwent EM (N = 201) with women who received MTX (N = 344). All women in the EM group had a declining trend of hCG. The MTX group had higher pretreatment hCG and higher rates of yolk sac or embryo presence on ultrasound. Eventual surgical treatment rate was higher in the MTX group compared with the EM group (39 [11.3%] vs. 9 [4.5%], P = 0.006), with no difference in the treatment failure rate or tubal rupture rate. In a subgroup analysis of women with pretreatment hCG between 1000 and 2000 mIU/mL, eventual surgical treatment, treatment failure, and tubal rupture rates did not differ between groups. Logistic regression analysis revealed that eventual surgical treatment was independently associated with hCG levels less than 1000 mIU/mL (adjusted odds ratio [aOR] 0.28, 95% confidence interval [CI] 0.14-0.56) and endometriosis (aOR 9.20, 95% CI 3.55-23.81). CONCLUSION: Expectant management of tubal pregnancies with pretreatment hCG levels less than 2000 mIU/mL and even between 1000 and 2000 mIU/mL and with a declining trend of hCG demonstrated lower or comparable rates of eventual surgical treatment, when compared with MTX treatment.

Factors associated with postcesarean blood transfusion: a case control study.

OBJECTIVE: Cesarean delivery (CD) is a known risk factor for postpartum hemorrhage. However, the characteristics associated with post-CD transfusion are not well-established. We aimed to assess blood transfusion rates and associated factors following CD. METHODS: A retrospective case-control study of women who underwent CD at a university hospital. The study group comprised all women who received blood transfusion following surgery. A control group of women who did not receive postoperative blood transfusion was assigned in a two-to-one ratio. RESULTS: During study period, the overall post-CD blood transfusion rate was 4.7%. The study group comprised 170 women, and the control group 340. Maternal age (aOR [95% CI]: 1.07 (1.03, 1.11), p = .001), parity (aOR [95% CI]: 1.26 (1.09, 1.47), p = .002), gestational hypertensive disorders (aOR [95% CI]: 4.07 (1.52, 10.91), p = .005), maternal comorbidities (aOR [95% CI]: 4.16 (1.88, 9.1), p < .001), lower predelivery hemoglobin level (aOR [95% CI]: 0.43 (0.34, 0.54), p < .001), and major placental abnormalities (aOR [95% CI]: 2.74 (1.04, 7.18), p = .04) were independently associated with blood transfusion requirement. Intrapartum characteristics associated with blood transfusion requirement included nonelective procedure (aOR [95% CI]: 3.21 (1.72, 5.99), p < .001), prolonged second stage of labor (aOR [95% CI]: 5.50 (2.57, 11.78), p < .001), longer duration of surgery (aOR [95% CI]: 1.03 (1.02, 1.04), p < .001), general anesthesia (aOR [95% CI]: 2.11 (1.14, 3.91), p = .02), and greater estimated operative blood loss (aOR [95% CI]: 5.72 (3.15, 10.36), p < .001). CONCLUSIONS: Among women who underwent CD, we identified 11 factors associated with blood transfusion following surgery. Prospective studies are warranted to assess the implementations of prophylactic interventions to reduce transfusion rates among those deemed at high risk for CD-related bleeding.
