Zorluk: Çok zorInformed Consent and Refusal

A 28-year-old woman, G1P0 at 28 weeks gestation, is brought to the emergency department following a high-speed motor vehicle collision. She is comatose with a Glasgow Coma Scale score of 6 and exhibits signs of severe intra-abdominal hemorrhage. Her blood pressure is 70/40 mm Hg, and her pulse is 140/min. Fetal heart rate monitoring shows a baseline of 150/min with moderate variability and no decelerations. The trauma surgery team determines that an emergent exploratory laparotomy is required to save her life. Emergency medical personnel provide the patient's wallet, which contains a signed, witnessed, and legally valid advance directive explicitly refusing the administration of all whole blood and blood components under any circumstances. A medical alert bracelet on her wrist also states "NO BLOOD PRODUCTS." Her husband arrives shortly after and confirms she is a devout Jehovah's Witness. He states, "She would rather die than receive a blood transfusion. You must not give her blood." The surgeon is highly concerned that the patient will not survive the laparotomy without blood product support.

Which of the following is the most appropriate next step in management?

  1. Proceed immediately with the exploratory laparotomy using blood conservation techniques, while withholding blood products.Cevap
  2. B
    Postpone the exploratory laparotomy until the hospital ethics committee can urgently convene to provide guidance on fetal beneficence.
  3. C
    Transfer the patient to the intensive care unit for palliative comfort measures, as she is unlikely to survive the surgical intervention without blood.
  4. D
    Administer blood products under the emergency exception to informed consent because the patient currently lacks legal competence.
  5. E
    Request the appointment of an independent surrogate for the fetus to authorize the administration of maternal blood products.

Cevap

Proceed immediately with the exploratory laparotomy using blood conservation techniques, while withholding blood products.
This patient presents in hemorrhagic shock requiring emergent surgery, but possesses a valid advance directive refusing blood products, which is corroborated by her highest-priority surrogate (her husband). The ethical principle of respect for patient autonomy dictates that a decisionally capable adult has the right to refuse any medical treatment, even if that refusal is life-threatening. This principle legally and ethically extends to incapacitated patients who clearly documented their wishes prior to losing capacity. Furthermore, according to major medical societies including the American College of Obstetricians and Gynecologists (ACOG), pregnancy is not an exception to the principle of informed refusal. A pregnant woman's autonomous refusal of treatment must be respected, even if it results in the death of a viable fetus. Therefore, the physician must honor the refusal of blood products. However, because the patient has not refused surgical intervention, the physician must still provide all other consented life-saving care, which involves proceeding with the emergent laparotomy using blood conservation techniques.

Adım Adım Çözüm

1
Assess the patient's clinical status and required interventions.
The patient is in hemorrhagic shock requiring emergent laparotomy and would typically require a blood transfusion.
To identify life-threatening injuries and the standard-of-care treatments required to stabilize them.
2
Evaluate the validity of the patient's prior expressed wishes.
The patient has a legally valid advance directive and a medical alert bracelet refusing blood, which is strongly corroborated by her husband.
To determine if the patient's autonomous wishes regarding treatment are documented, as she currently lacks clinical decision-making capacity.
3
Apply medical ethics principles regarding pregnancy and treatment refusal.
Maternal autonomy and valid advance directives override fetal beneficence; therefore, blood products must be withheld.
Pregnancy does not negate a competent adult's right to refuse life-saving medical treatment.
4
Determine the next best step in management based on consented treatments.
Perform the required and non-refused intervention (laparotomy) while respecting the specific refusal (withholding blood).
To maximize patient survival using available, permitted methods without violating the patient's autonomy.

Anahtar Kavram

A competent pregnant woman's autonomous refusal of life-saving medical treatment, including valid advance directives enacted while she is incapacitated, must be respected even if it compromises a viable fetus.
