Placental Abruption — When Class 3 Hemorrhagic Shock Resuscitation Fails to Stabilise

When placental abruption is complicated by Class 3 hemorrhagic shock and the initial resuscitation protocol does not achieve the required haemostatic and haemodynamic targets, clinical management must escalate to address a higher degree of blood loss.

Clinical situation

This protocol applies when resuscitation for Class 3 hemorrhagic shock (estimated blood loss 30–40%) has not stabilised the patient and haemorrhage has progressed to the Class 4 range (estimated blood loss >40%).

Prior line — failure condition

The preceding resuscitation — Class 3 hemorrhagic shock management with cross-matched packed red blood cells, fresh frozen plasma, cryoprecipitate, and platelets — did not reach its required targets: fibrinogen maintained above 50 to 100 mg/dL, platelet count maintained above 50 × 10³/µL, and stabilisation of vital signs. Failure to meet these goals triggers escalation to this protocol.

Next-step approach (partial)

Escalated management involves immediate activation of a massive transfusion protocol and use of O-negative blood products, combined with specialist consultation. The approach may extend to additional coagulation-directed therapy depending on the clinical picture. The full sequence and criteria remain in the complete protocol.
