Postpartum Hemorrhage Treatment Sequence

Use quantitative blood-loss measurement rather than visual estimation, and treat continued abnormal bleeding with any hemodynamic deterioration as an obstetric emergency. A cumulative blood loss of 1,000 mL or more accompanied by signs or symptoms of hypovolemia within 24 hours after birth defines PPH regardless of delivery route; primary PPH occurs within 24 hours, whereas secondary PPH occurs from 24 hours to 6-12 weeks postpartum. jacc+1jaccTeam-Based Care of Women With Cardiovascular Disease From Pre-Conception Through Pregnancy and Postpartum: JACC Focus Seminar 1/5PubMedPostpartum Hemorrhage - StatPearls - NCBI Bookshelf - NIH

At recognition, call obstetric anesthesia, the blood bank, and senior obstetric support; establish resuscitation and initiate the institutional massive-transfusion pathway if bleeding is rapid or ongoing. Care bundles using quantitative measurement, senior escalation at 1,000 mL and 1,500 mL, point-of-care hemostasis testing at 1,000 mL or more, and early tranexamic acid were associated with less progression to severe PPH of at least 2,500 mL and fewer transfusions.

Obtain a CBC with platelet count, fibrinogen, and coagulation testing while treatment proceeds; do not defer source control pending results. In severe ongoing PPH, standard fibrinogen testing or viscoelastic testing with ROTEM or TEG provides earlier actionable assessment of hypofibrinogenemia than waiting for later clinical coagulopathy.

Perform a focused 4 Ts assessment during resuscitation: Tone (uterine atony), Trauma (laceration, hematoma, uterine rupture or inversion), Tissue (retained products or abnormal placentation), and Thrombin (acquired or inherited coagulopathy). Uterine atony is the most common cause of primary PPH, but trauma, retained tissue, and coagulopathy require fundamentally different interventions.

A boggy, enlarged uterus supports atony and warrants uterine massage, bimanual compression, and uterotonics. Continued brisk bleeding with a firm contracted uterus should prompt inspection for cervical, vaginal, perineal, or operative-site trauma; assess for concealed puerperal genital hematoma when pain, pressure, or hemodynamic compromise exceeds visible blood loss.

If placental delivery is incomplete, bleeding persists with suspected retained tissue, or delayed hemorrhage develops, evaluate for retained or residual products of conception. Secondary hemorrhage is commonly associated with retained products, infection, subinvolution of the placental site, lacerations, uterine atony, and inherited coagulation disorders; pelvic imaging can help define retained products, hematoma, uterine dehiscence, or other structural causes. jacc+2jaccTeam-Based Care of Women With Cardiovascular Disease From Pre-Conception Through Pregnancy and Postpartum: JACC Focus Seminar 1/5pubs rsnaSecondary Postpregnancy Hemorrhage: Guide for Diagnosis and ...pubs rsnaImaging of Antepartum and Postpartum Hemorrhage - RSNA Journals

For suspected atony, begin uterine massage and bimanual compression with oxytocin-based uterotonic treatment. If bleeding continues, select an additional uterotonic with a different mechanism rather than repeating ineffective treatment; the choice depends on contraindications and the clinical speed of hemorrhage.

Administer intravenous tranexamic acid as soon as PPH is diagnosed and within 3 hours after birth, as an adjunct to standard PPH treatment rather than as a substitute for uterotonics, repair, tamponade, transfusion, or surgery. In structured treatment bundles, tranexamic acid was given upon recognition of abnormal bleeding and repeated if bleeding continued.

Carboprost is a practical second-line uterotonic for refractory atony after uterine massage and oxytocin when methylergonovine is ineffective or contraindicated. Give 250 micrograms intramuscularly and repeat every 15-30 minutes as needed; avoid or use exceptional caution in asthma because bronchospasm risk makes asthma a relative contraindication.

For refractory uterine bleeding after uterotonics, use intrauterine balloon tamponade as an early uterus-preserving mechanical option when the uterus is the likely bleeding source. Failure of tamponade, uncontrolled bleeding, or concern for a surgical source should prompt operative escalation without delay.

Uterus-preserving operative options include uterine compression sutures such as B-Lynch, Hayman, or Cho techniques; uterine artery ligation; stepwise uterine devascularization; internal iliac artery ligation; and selective arterial embolization. Selection depends on delivery route, bleeding site and volume, hemodynamic tolerance, and immediate technical and personnel availability.

Arterial embolization can preserve reproductive function but requires a stable enough patient, immediate interventional radiology capability, and no delay in control of exsanguinating hemorrhage. High-risk patients, particularly those with placenta accreta spectrum or placenta previa, should be managed at centers with 24-hour multidisciplinary and interventional radiology resources when feasible.

Proceed to peripartum hysterectomy when conservative medical, mechanical, and vascular-control measures cannot achieve hemostasis or when the clinical situation makes fertility-preserving approaches unsafe. In a tertiary-center series of PPH requiring massive-transfusion protocol activation, 19% underwent peripartum hysterectomy and 61% required ICU admission, underscoring the need to avoid delayed escalation.

During severe ongoing PPH, monitor fibrinogen early because it is the first coagulation factor to fall to critical levels. A fibrinogen concentration below 2 g/L has been reported to predict progression to severe bleeding, and values below 200 mg/dL are an indication for component replacement; target at least 150-200 mg/dL during massive transfusion.

Use cryoprecipitate or fibrinogen concentrate according to the institution's PPH protocol and product availability. A usual cryoprecipitate dose of 10 units is estimated to increase fibrinogen by approximately 100 mg/dL, but repeat laboratory or viscoelastic assessment should determine whether the target has been achieved.

When hemorrhage is massive, activate a ratio-driven blood-product protocol rather than waiting for isolated laboratory abnormalities; published obstetric protocols use RBC:FFP:platelet ratios of 6:4:1, 4:4:1, or 1:1:1, although these ratios are extrapolated from trauma literature and no single obstetric ratio is established. PubMedPubMedManagement of Postpartum Haemorrhage

In the nonmassively bleeding phase, a restrictive RBC transfusion threshold of hemoglobin below 7 g/dL is preferred. With active bleeding, RBC transfusion thresholds may shift to hemoglobin 7-9 g/dL depending on local protocol and maternal comorbidity; continue to correct hypothermia, acid-base derangement, and citrate-associated hypocalcemia during major transfusion.

For hemorrhage from 24 hours through 6-12 weeks postpartum, first reassess hemodynamic status and quantify active loss, then prioritize retained products of conception, infection, subinvolution of the placental site, laceration, uterine atony, and inherited coagulation disorders. This timing distinction matters because delayed bleeding should not be presumed to be uncomplicated uterine atony. jacc+1jaccTeam-Based Care of Women With Cardiovascular Disease From Pre-Conception Through Pregnancy and Postpartum: JACC Focus Seminar 1/5PubMedPostpartum Hemorrhage - StatPearls - NCBI Bookshelf - NIH

Use pelvic imaging when the clinical assessment suggests retained products, genital tract hematoma, uterine rupture or dehiscence, or another structural source. Imaging is particularly useful when bleeding persists despite initial bedside assessment or when the source is not visible on examination. pubs rsna+1pubs rsnaSecondary Postpregnancy Hemorrhage: Guide for Diagnosis and ...pubs rsnaImaging of Antepartum and Postpartum Hemorrhage - RSNA Journals

If secondary hemorrhage is hemodynamically significant, initiate the same resuscitation, blood-bank, and hemostatic pathway used for primary PPH while arranging source-directed treatment. Delayed presentation does not reduce the need for urgent fibrinogen assessment and procedural escalation when bleeding is severe. jacc+1jaccTeam-Based Care of Women With Cardiovascular Disease From Pre-Conception Through Pregnancy and Postpartum: JACC Focus Seminar 1/5PubMedManagement of Postpartum Haemorrhage
