Aspirin is not typically recommended for postpartum preeclampsia management. The primary treatments for postpartum preeclampsia include antihypertensive medications (such as labetalol 200-400 mg orally twice daily, nifedipine 10-20 mg orally every 4-6 hours, or hydralazine 10-25 mg IV as needed) and magnesium sulfate (4-6 g IV loading dose followed by 1-2 g/hour continuous infusion for 24 hours) to prevent seizures in severe cases. Unlike prevention of preeclampsia during pregnancy, where low-dose aspirin (81-162 mg daily) started before 16 weeks' gestation is beneficial for high-risk women, aspirin has no established role once preeclampsia has developed, especially postpartum. Some studies suggest that prenatal low-dose aspirin use may be associated with reduced incidence of postpartum hypertension among women with preeclampsia 1. However, this does not necessarily imply a role for aspirin in the management of postpartum preeclampsia. Postpartum preeclampsia requires close monitoring of blood pressure, symptoms (headache, visual changes, epigastric pain), and laboratory values (liver enzymes, platelets, creatinine). Most cases resolve within days to weeks after delivery, but some women may require antihypertensive therapy for several weeks. Patients should be educated about the importance of prompt medical attention for symptoms like severe headache, visual disturbances, or shortness of breath, as postpartum preeclampsia can lead to serious complications including stroke, seizures, and pulmonary edema. The use of magnesium sulfate in postpartum preeclampsia is generally reserved for severe cases or those with neurologic symptoms, as it can have significant side effects and may not be necessary for all patients with postpartum hypertension 2. In terms of prevention, low-dose aspirin has been shown to be effective in reducing the risk of preeclampsia in high-risk women when started before 16 weeks' gestation 3, 4. However, this is a separate consideration from the management of postpartum preeclampsia. Key points to consider in the management of postpartum preeclampsia include:
- Close monitoring of blood pressure and symptoms
- Use of antihypertensive medications as needed
- Reserved use of magnesium sulfate for severe cases or those with neurologic symptoms
- Education of patients on the importance of prompt medical attention for concerning symptoms
- Consideration of the potential benefits and risks of low-dose aspirin in the prevention of preeclampsia during pregnancy, but not in the management of postpartum preeclampsia.
