A 74-year-old man with a history of hypertension and atrial fibrillation treated with apixaban is brought to the emergency department by emergency medical services. His wife reports that he experienced a sudden, severe occipital headache and intractable vomiting 45 minutes ago before collapsing. Upon arrival in the trauma bay, he is unresponsive. His eyes do not open to pain, he makes incomprehensible sounds, and he exhibits abnormal extensor posturing to painful stimuli. His blood pressure is 220/115 mmHg, heart rate is 52/min, and respiratory rate is 10/min with irregular breathing patterns.
Arrange the following clinical interventions in the most appropriate, evidence-based sequential order for the acute management of this patient.
- 1Perform endotracheal intubation and initiate mechanical ventilation.
- 2Obtain an emergent non-contrast computed tomography (CT) scan of the head.
- 3Administer andexanet alfa and initiate a titratable intravenous antihypertensive infusion.
- 4Perform an emergent suboccipital craniectomy with hematoma evacuation.
- 5Transfer the patient to the neuro-intensive care unit for continuous invasive monitoring.
Cevap
The correct sequence is: Endotracheal intubation, followed by a non-contrast CT of the head, followed by administration of andexanet alfa and an antihypertensive, followed by suboccipital craniectomy, and finally transfer to the neuro-ICU.
The patient presents with Cushing's triad (hypertension, bradycardia, irregular breathing) and a GCS of 5, highly suggestive of an intracranial mass lesion causing brainstem compression, such as a cerebellar hemorrhage. In any emergency, the ABCs take precedence; therefore, endotracheal intubation is the first step. Once the airway is secure, a non-contrast head CT must be obtained to confirm the diagnosis and rule out ischemic etiologies. After confirming a hemorrhage, medical stabilization must occur before surgery; because the patient is on apixaban, urgent reversal with andexanet alfa (or 4-factor PCC) and strict blood pressure control are required to prevent uncontrollable surgical bleeding. Finally, the definitive treatment for a large, symptomatic cerebellar hemorrhage is emergent suboccipital craniectomy, followed by monitoring in the neuro-ICU.

The management of acute cerebellar hemorrhage requires a strict sequence of airway stabilization, diagnostic imaging, medical reversal of coagulopathy, and finally definitive surgical decompression.
