Summary
Definition
History and exam
Key diagnostic factors
- estimated blood loss ≥1000 mL within 24 hours of birth (including intrapartum loss)
- uterine atony
- obstetric lacerations and/or expanding hematomas
- signs of hypovolemia
- hypotension
- retained tissue (placenta, membranes, or placenta accreta spectrum)
- uterine defect on bimanual examination
Other diagnostic factors
- symptoms of hypovolemia
- uterine tenderness (secondary PPH)
- signs of infection, e.g., fever (secondary PPH)
Risk factors
- placenta previa/low lying placenta
- placenta accreta spectrum
- platelet count <50,000 per microliter
- active antepartum bleeding
- inherited coagulopathy
- acquired coagulopathy
- history of PPH in prior delivery
- operative (assisted) vaginal delivery
- current use of therapeutic anticoagulation
- prior cesarean delivery, uterine surgery, or multiple laparotomies
- uterine overdistension (multiple gestation, polyhydramnios, fetal macrosomia with estimated fetal weight >4000 g)
- grand multiparity (>4 prior births)
- large uterine myomas
- class III obesity (BMI >40)
- pre-existing maternal anemia
- prolonged labor or precipitous delivery
- labor induction or augmentation with prolonged use of oxytocin
- magnesium sulfate use
- cesarean delivery
- placental abruption
- severe preeclampsia or HELLP syndrome
- intrauterine fetal demise (IUFD)
- intrapartum infection
- SSRI or SNRI use in the month before delivery
Diagnostic tests
1st tests to order
- quantification of blood loss
- blood type and crossmatch
Tests to consider
- CBC
- uterine ultrasound
- coagulation profile (PT, PTT, INR, fibrinogen)
- inherited coagulation assays
- diagnostic laparotomy
- CT abdomen/pelvis
Emerging tests
- thromboelastography (TEG) or rotational thromboelastometry (ROTEM®)
- app-based blood loss quantification technology
Treatment algorithm
primary postpartum hemorrhage: initial presentation
primary postpartum hemorrhage: refractory to initial interventions
secondary postpartum hemorrhage
postpartum hemorrhage resolved
