Meningococcal sepsis with shock, coagulopathy, and no ICU bed
A 19-year-old university student presents with a 12-hour history of fever, headache, and a rapidly spreading petechial rash. He is confused, with a GCS of 13. Blood pressure is 84/48 mmHg, heart rate 130/min, capillary refill 4 seconds, and lactate 4.2 mmol/L. Platelets are 70 × 10⁹/L and INR 1.6. He has no neck stiffness. He has a documented penicillin allergy with rash only. The hospital has no available ICU bed for 6 hours; the nearest extracorporeal support centre is 2 hours away. Meningococcal PCR is available but results take 4 hours. The emergency department is busy and has one negative-pressure room.
1. State your immediate antibiotic choice and dose, and explain how the penicillin allergy affects your decision. What else must be given in the first hour?

I would give ceftriaxone 2 g IV immediately, without waiting for PCR or LP. The documented penicillin allergy is a rash only, not anaphylaxis; cephalosporins are generally safe in that situation. If there were a history of anaphylaxis, I would use meropenem or chloramphenicol according to local protocol after risk assessment, but I would not delay antibiotics. In the first hour I would also give oxygen, rapid IV crystalloid boluses (20–30 mL/kg) and early vasopressors if needed, take blood cultures, and consider dexamethasone 10 mg IV before or with the first antibiotic dose. The reasoning is that meningococcal sepsis is rapidly fatal and antibiotics are time-critical; dexamethasone may reduce hearing loss in bacterial meningitis but should not delay resuscitation.
2. Would you perform a lumbar puncture in the emergency department? Justify your answer.

I would not perform a lumbar puncture now. He has shock, coagulopathy (INR 1.6, platelets 70), and a reduced GCS-all relative contraindications. The diagnosis can be started on clinical grounds and blood PCR; LP can be done later if it is safe and if it will change management. The reasoning is that LP in the presence of shock and coagulopathy risks herniation and spinal bleeding, and it will not alter the immediate antibiotic decision. I would document the plan to reconsider LP after stabilisation.
3. How would you prioritise care when there is no ICU bed for 6 hours? Include infection control and communication.
Read the worked answer
When no ICU bed is available, I would resuscitate in the emergency department and treat the ED as a temporary critical care area. I would isolate him in the negative-pressure room, use droplet precautions, and notify public health. I would start antibiotics and fluids, insert an arterial line if possible, and use vasopressors. I would communicate early with the ICU and the retrieval service, document the capacity problem, and escalate to hospital management. The reasoning is that meningococcal sepsis is a public health emergency and requires source control and organ support; the lack of an ICU bed does not change the immediate treatment. I would also identify close contacts and arrange chemoprophylaxis.
