Placenta Accreta and Refusal of Blood Products
36-year-old G4P3 at 34 weeks 2 days with complete placenta previa and suspected placenta accreta; she has had two prior cesarean deliveries. She is a Jehovah's Witness and refuses allogeneic blood transfusion, has an advance directive, and understands the risk of death. Hemoglobin is 9.6 g/dL, platelets 210,000/µL, and fibrinogen 410 mg/dL. Ultrasound and MRI show loss of the normal uteroplacental interface and possible bladder invasion. She takes iron and prenatal vitamins. She is at a tertiary center with maternal-fetal medicine, gynecologic oncology, interventional radiology, and a level III neonatal unit. She agrees to surgery but not to blood products. She asks whether cell salvage can be used and whether the team will 'just let her die' if she bleeds. She has no other medical conditions.
1. How should the team respond to her refusal of blood products while maintaining ethical and legal standards?

The team should confirm that she has decision-making capacity, understands the risks including death, and is not being coerced. A competent adult's informed refusal must be respected, and transfusion should not be given against her documented wishes. The discussion should explore acceptable alternatives, including preoperative iron and erythropoietin, tranexamic acid, acute normovolemic hemodilution, cell salvage with a continuous circuit if her religious interpretation permits it, fibrin sealants, and interventional radiology. Involve ethics, anesthesia, blood bank, and hospital legal counsel early. She should not be abandoned if the center cannot honor her wishes; transfer can be offered if she agrees. Document the conversation, her advance directive, and the specific products accepted or refused in the chart and operative consent.
2. Outline the multidisciplinary preoperative plan for suspected placenta accreta at 34 weeks.
Read the worked answer
Plan a scheduled cesarean hysterectomy before labor, generally between 34 and 36 weeks after corticosteroids if the gestational age is appropriate. Assemble maternal-fetal medicine, gynecologic oncology, anesthesia, interventional radiology, neonatology, and blood bank. Optimize hemoglobin with iron and consider erythropoietin. Prepare a massive transfusion protocol even though she refuses blood, because team readiness and documentation matter if she changes her mind. At surgery, place ureteral stents, consider prophylactic iliac balloon catheters with the understanding that evidence is mixed, give tranexamic acid, and leave the placenta in situ rather than attempting manual removal. Proceed to hysterectomy with meticulous hemostasis. Use cell salvage only if she accepts it. Arrange neonatal resuscitation and postoperative critical care.
3. If she becomes hypotensive and unresponsive intraoperatively, may the team transfuse?
Read the worked answer
No. A valid, documented refusal made while she had capacity remains binding if she later becomes incapacitated, unless there is clear evidence that she revoked it. The team may not covertly transfuse based on convenience or presumed best interests. They should continue all acceptable resuscitation measures and obtain an urgent ethics and legal consultation if there is ambiguity about her directive. If she explicitly changes her mind while still competent, that revocation should be documented and transfusion provided. The exception would be a minor or a patient without decision-making capacity and without a valid directive, which is not this case. Document the events, the refusal, and the interventions offered.
