A 5-year-old boy with a known history of severe hemophilia A is brought to the pediatric emergency department after falling from a playground structure and striking his head. His parents report that he has vomited twice since the fall and appears unusually lethargic. On primary survey, his airway is patent, breathing is unlabored, and perfusion is adequate. His Glasgow Coma Scale score is 13. Arrange the following management steps in the most appropriate chronological order.
- 1Administer intravenous recombinant factor VIII concentrate to achieve 100% activity.
- 2Obtain an emergent non-contrast computed tomography (CT) scan of the head.
- 3Request an emergent pediatric neurosurgery consultation.
- 4Admit the patient to the pediatric intensive care unit (PICU).
Cevap
The correct sequence is to first administer factor VIII concentrate, followed by a non-contrast head CT, then obtain a neurosurgery consultation, and finally admit to the PICU.
In any patient with severe hemophilia presenting with significant head trauma or signs of increased intracranial pressure (such as vomiting and lethargy), an intracranial hemorrhage must be assumed. The most critical, life-saving step is the immediate administration of factor VIII concentrate to achieve 100% factor activity. This must be done before the patient is sent to radiology for a CT scan, as the time taken for imaging can allow catastrophic, unchecked bleeding. Once factor is administered and hemostasis is initiated, a non-contrast head CT is performed to confirm the diagnosis. Following imaging, a neurosurgery consultation is obtained to assess the need for operative intervention. Finally, the patient is admitted to the PICU for serial neurologic examinations and continued factor replacement therapy.
Adım Adım Çözüm
Anahtar Kavram
In patients with severe bleeding disorders presenting with significant head trauma, factor replacement therapy must precede diagnostic neuroimaging.
