A 22-year-old G1P1 woman who underwent a cesarean section 5 days ago for failure to progress presents with a fever of 39.0°C (102.2°F), lower abdominal pain, and foul-smelling lochia. She was started on intravenous clindamycin and gentamicin. After 48 hours of therapy, her fever persists, and she still has significant uterine tenderness. Which of the following is the most appropriate next step?
Explanation: Postpartum endometritis is typically a polymicrobial infection. The standard treatment with clindamycin (for anaerobes and Gram-positives) and gentamicin (for Gram-negatives) is effective for most cases. When a patient fails to respond within 48-72 hours, antibiotic resistance should be suspected. The most common resistant organism is Enterococcus, which is not covered by clindamycin or gentamicin. Therefore, adding ampicillin to the regimen to cover Enterococcus is the appropriate next step. Imaging or surgical intervention is considered if there is suspicion of an abscess or septic pelvic thrombophlebitis.
A 31-year-old G2P2 woman presents to the emergency department 5 weeks postpartum with a 1-week history of progressive shortness of breath, orthopnea, and lower extremity edema. Her pregnancy was uncomplicated. Her blood pressure is 105/65 mm Hg, heart rate is 115/min, and respiratory rate is 24/min. Physical examination reveals jugular venous distension, bibasilar crackles on lung auscultation, and 2+ pitting edema to the mid-calves. Which of the following diagnostic tests is most likely to confirm the diagnosis?
Explanation: The patient's presentation in the late postpartum period with signs and symptoms of acute congestive heart failure (dyspnea, orthopnea, JVD, crackles, edema) is highly suspicious for peripartum cardiomyopathy (PPCM). The diagnosis of PPCM is confirmed by an echocardiogram demonstrating new-onset left ventricular systolic dysfunction, typically defined as an ejection fraction less than 45%. While a chest x-ray would show signs of heart failure (e.g., cardiomegaly, pulmonary edema), it does not confirm the underlying cardiac dysfunction.
A 33-year-old G1P1 woman is at her 6-week postpartum visit. She is exclusively breastfeeding and wants to start an effective, reversible contraceptive. She has a history of migraine headaches with aura. Her blood pressure is 118/76 mm Hg. Which of the following is the most appropriate recommendation?
Explanation: This patient has a contraindication to estrogen-containing contraceptives due to her history of migraine with aura, which is associated with an increased risk of ischemic stroke. Therefore, combined oral contraceptives are not an option. The etonogestrel implant is a progestin-only, long-acting, highly effective contraceptive that is safe during breastfeeding and in women with migraine with aura. It is a superior choice compared to less effective methods like a diaphragm or natural family planning for a patient desiring high efficacy.
A 30-year-old G2P2 woman is at her 6-week postpartum visit following an uncomplicated vaginal delivery. She is exclusively breastfeeding and wants a long-acting reversible contraceptive. She has a history of severe dysmenorrhea that was well-managed with NSAIDs prior to pregnancy. She is interested in a levonorgestrel-releasing IUD. What is the most appropriate counseling regarding the timing of IUD placement?
Explanation: At 4-6 weeks postpartum, the uterus is sufficiently involuted, and the risk of uterine perforation with IUD insertion returns to baseline. It is safe and convenient to place the IUD at the 6-week postpartum visit. There is no need to wait for the return of menses, which can be delayed for many months in breastfeeding women. The levonorgestrel-releasing IUD is safe during lactation and is an excellent choice for this patient, as it may also help with her underlying dysmenorrhea.
A 32-year-old G1P1 woman is seen for her 6-week postpartum visit. Her pregnancy was complicated by diet-controlled gestational diabetes mellitus (GDM), diagnosed at 26 weeks. Her BMI is 32 kg/m². She is asymptomatic. A fasting blood glucose on the day after delivery was 95 mg/dL. Which of the following is the most appropriate next step in management for this patient?
Explanation: Women with a history of GDM are at a significantly increased risk for developing type 2 diabetes. ACOG recommends screening for persistent diabetes or prediabetes 4 to 12 weeks postpartum. The preferred screening test is a 75-g, 2-hour oral glucose tolerance test (OGTT). Hemoglobin A1c can be falsely low in the postpartum period due to pregnancy-related increased red blood cell turnover. Delaying screening is inappropriate due to the high risk of underlying glucose intolerance.
