Background

Postpartum period is defined as up to 6 weeks after delivery (some complications up to 12 weeks)
Postpartum patients may present to the ED rather than to OB for emergent complications
Key EM concern: postpartum hemorrhage is the most common cause of maternal death worldwide

Emergencies

3rd Trimester/Postpartum Emergencies

Postpartum hemorrhage

Defined as >500 mL blood loss (vaginal delivery) or >1000 mL (cesarean)
Most common cause: uterine atony (70-80%) — risk factors include prolonged labor, overdistension, chorioamnionitis
Other causes (4 T's): Tone (atony), Trauma (lacerations, uterine rupture), Tissue (retained products), Thrombin (coagulopathy)
Management: uterine massage, uterotonics (oxytocin, methylergonovine, misoprostol, carboprost), transfusion, OB consultation, may need surgical intervention

Postpartum endometritis

Polymicrobial uterine infection, typically 2-10 days after delivery
Higher risk after cesarean section
Fever, uterine tenderness, purulent lochia
Treatment: IV broad-spectrum antibiotics (clindamycin + gentamicin is classic regimen)

Postpartum preeclampsia / Eclampsia

Can occur up to 6 weeks postpartum, even without antepartum diagnosis
Headache, visual changes, RUQ pain, hypertension, proteinuria
Treat with IV magnesium sulfate for seizure prophylaxis/treatment and antihypertensives

Peripartum Cardiomyopathy

Heart failure occurring in last month of pregnancy to 5 months postpartum
Presents with dyspnea, edema, orthopnea
Echocardiography for diagnosis; manage as heart failure

DVT / Pulmonary Embolism

Postpartum period is highest risk for VTE
Low threshold for workup — D-dimer less useful in postpartum period
CTA for suspected PE; compression US for DVT

Postpartum Depression / Psychosis

Depression: common (10-15%), screen with Edinburgh Postnatal Depression Scale
Psychosis: rare but dangerous — onset typically 2-4 weeks postpartum; hallucinations, delusions, risk of harm to self/infant → psychiatric emergency, admit

Other

Mastitis / breast abscess
Wound infection / dehiscence (cesarean)
Ovarian vein thrombophlebitis (septic pelvic thrombophlebitis)
Urinary retention

Disposition

Low threshold for OB consultation
Admit: hemorrhage, endometritis, preeclampsia/eclampsia, cardiomyopathy, PE, psychosis
Discharge: mild mastitis, minor wound issues — with close OB follow-up and return precautions
