Principes fondamentaux de la prise en charge des hémorragies du post-partum

Postpartum hemorrhage (PPH) remains a leading cause of maternal mortality worldwide, and prompt, evidence-based management is critical to reducing morbidity and death. The cornerstone of PPH management centers on early recognition, rapid assessment, and implementation of a structured, stepwise intervention protocol.

Initial priorities include simultaneous resuscitation and diagnosis: securing intravenous access with two large-bore catheters, initiating crystalloid fluid replacement, obtaining urgent laboratory studies—including complete blood count, coagulation profile, fibrinogen level, and type-and-crossmatch—and administering supplemental oxygen. Uterine atony—the most common etiology—must be addressed immediately via bimanual uterine massage and first-line uterotonic agents, typically intravenous or intramuscular oxytocin.

If bleeding persists despite oxytocin, second-line uterotonics such as intramuscular methylergonovine (contraindicated in hypertension), intravenous carboprost, or sublingual misoprostol are administered based on clinical context and availability. Concurrently, clinicians must systematically evaluate and treat other potential causes using the “4 Ts” mnemonic: Tone (uterine atony), Trauma (cervical, vaginal, or perineal lacerations; uterine inversion or rupture), Tissue (retained placental fragments or placenta accreta spectrum), and Thrombin (coagulopathy—either preexisting or consumptive, as in amniotic fluid embolism or severe preeclampsia).

Invasive interventions—including intrauterine balloon tamponade (e.g., Bakri or Sengstaken-Blakemore balloons), uterine artery embolization, or surgical techniques such as uterine compression sutures (e.g., B-Lynch), pelvic vessel ligation, or hysterectomy—are escalated according to severity, hemodynamic stability, and institutional resources. Multidisciplinary coordination—among obstetricians, anesthesiologists, hematologists, and transfusion medicine specialists—is essential throughout the algorithm.

Prevention remains integral: active management of the third stage of labor—including prophylactic oxytocin administration, controlled cord traction, and uterine massage—reduces PPH incidence by over 60%. Risk stratification antenatally and readiness drills for massive transfusion and hemorrhage response further strengthen system-level preparedness.
