Abstract
Postpartum hemorrhage (PPH) was determined by visual estimates, which have largely been replaced by gravimetric quantitative blood loss (QBL) with improved sensitivity and specificity. The QBL method involves weighing sponges and measuring fluid in suction canisters. Massive hemorrhage may also result from surgical causes in pregnant or postpartum women. Placental abruption is the premature separation of a normally situated placenta, which may be partial or complete. Uterine rupture may occur in an unscarred uterus, at the site of a previous uterine scar from a cesarean section, or a full-thickness incision secondary to gynecologic surgery. The most common treatment method for placenta accreta spectrum remains a cesarean hysterectomy. Uterine inversion often presents with a profound shock of neurogenic and hemorrhagic origin. Consumptive and dilutional coagulopathies secondary to extensive blood loss and crystalloid replacement are PPH’s most common bleeding disorders. Uterine devascularization is a surgical technique for PPH due to atony, placenta previa, and trauma.
