A trauma team evaluates a 32-year-old male construction worker who fell 15 feet from a scaffold, striking his head on a concrete slab. On primary survey, he does not open his eyes, makes incomprehensible sounds, and exhibits decorticate posturing to painful stimuli. His right pupil is 8 mm and nonreactive to light. Vital signs show a blood pressure of 190/110 mmHg, a heart rate of 48/min, and a respiratory rate of 8/min with irregular breathing patterns.
Arrange the following management steps in the most appropriate chronological sequence for this patient.
- 1Perform rapid sequence endotracheal intubation
- 2Administer intravenous osmotic therapy
- 3Obtain a noncontrast head computed tomography scan
- 4Proceed with targeted decompressive craniotomy
Cevap
The correct sequence prioritizes the ABCs of trauma resuscitation followed by targeted interventions for impending brain herniation: Intubation -> Osmotic therapy -> CT scan -> Craniotomy.
The correct sequence adheres to established trauma and neurosurgical protocols. A patient presenting with a GCS of 6 and irregular respirations must first have their airway secured (intubation). Following the 'ABCs', the immediate life-threatening neurological emergency—uncal herniation indicated by a blown pupil, bradycardia, and hypertension (Cushing reflex)—must be temporized medically with osmotic therapy. Only after the patient is physiologically stabilized should they be transported for a noncontrast head CT to precisely localize the intracranial hemorrhage. Finally, armed with anatomical data from the CT, the neurosurgeon can perform definitive surgical decompression.

Anahtar Kavram
The primary management of severe traumatic brain injury with impending herniation follows a strict sequence: secure the airway, initiate medical temporization of intracranial pressure, identify the lesion via imaging, and perform definitive surgical decompression.
