A 19-year-old male college student is brought to the emergency department by his roommates because of confusion and a high fever. His roommates report that he complained of a severe headache and neck stiffness yesterday. Over the past few hours, he has become increasingly lethargic and developed a rapidly spreading purpuric rash on his lower extremities. He is oriented only to his name. His temperature is 39.8°C (103.6°F), blood pressure is 75/40 mmHg, heart rate is 138/min, respiratory rate is 26/min, and oxygen saturation is 94% on room air. The patient is moving all four extremities spontaneously.
Arrange the following management steps in the most appropriate sequential order for this patient.
- 1Establish intravenous access, draw blood cultures, and initiate a crystalloid fluid bolus.
- 2Administer empiric intravenous ceftriaxone and vancomycin.
- 3Perform a non-contrast computed tomography (CT) scan of the head.
- 4Perform a lumbar puncture for cerebrospinal fluid analysis.
Cevap
The correct sequence is to first establish IV access, draw cultures, and start fluids, followed immediately by empiric antibiotics, then a head CT, and finally a lumbar puncture.
The patient presents with signs of septic shock and meningococcemia (purpuric rash, fever, neck stiffness, altered mental status). The first step in management is always initial stabilization: securing ABCs. He requires immediate IV access, blood cultures, and fluid resuscitation for his hypotension. Following this, empiric antibiotics must be administered without delay. Because he has altered mental status, he meets the criteria for requiring a head CT prior to a lumbar puncture to avoid cerebral herniation. Therefore, the CT scan is performed next, and the lumbar puncture follows once the CT is deemed safe.
Adım Adım Çözüm
Anahtar Kavram
In patients with suspected bacterial meningitis and shock, initial stabilization with fluids and empiric antibiotics takes precedence over diagnostic imaging and procedures. If the patient has altered mental status, a head CT must precede the lumbar puncture.
