An Update to ED management of postpartum hemorrhage and the 4 Ts DDx



* Recognition of postpartum hemorrhage is by gestalt



* Defined as more bleeding than expected after vaginal delivery or abortion (classically defined and >500 mL blood loss but difficult to measure accurately - if it looks bad/blood filling the vaginal vault, start resuscitation).





* As soon as postpartum hemorrhage is identified, activate the team



* Call OBGYN but if unavailable, call general surgery





* Identify the cause(s) of the hemorrhage: 4 Ts differential diagnosis of postpartum hemorrhage



* Tone (uterine atony) *most common cause post-delivery

* Tissue (retained placenta or clots) *most common cause post-abortion

* Trauma (large vaginal or cervical tears, uterine rupture)

* Thrombin (pre-existing or acquired coagulopathy i.e. DIC)





* Blood products (RBC +/- platelets, FFP, fibrinogen); consider massive hemorrhage protocol



* Postpartum patients who are hemorrhaging tend to have low fibrinogen with an increased risk for DIC, so have a low threshold to give fibrinogen





* If atony, give 4 uterotonics (oxytocin, misoprostol, methergine, and carboprost)



* If the pregnancy was <20 weeks, oxytocin is still recommended but does not play a major role

* If bleeding persists despite the uterotonics, consider direct tamponade with a Bakri balloon.

* If there is concern for uterine inversion stop uterotonics





* Consider TXA as per WOMAN Trial

* Consider developing a mother-child care set for efficient management of postpartum hemorrhages
