Why It Matters
This case forces prioritization across cardiopulmonary, gastrointestinal, trauma, neurologic, and infectious-disease emergencies rather than recognizing each diagnosis in isolation.
Boss Case
A 34-year-old pregnant patient at 30 weeks presents after a witnessed generalized seizure. She is febrile to 39.4°C, blood pressure is 196/118 mm Hg, and oxygen saturation is 88% on a nonrebreather. Her partner reports two days of headache and confusion. She has neck discomfort but no obvious trauma. Lung examination reveals diffuse crackles, and bedside ultrasound shows bilateral B-lines with a small, poorly collapsible IVC.
Committing question: What is the immediate syndrome-level priority?
Expert move: Treat this as a neurologic hypertensive emergency with respiratory failure: support oxygenation and ventilation, control severe blood pressure, manage seizure activity, and urgently evaluate for pregnancy-related hypertensive disease and intracranial pathology.
Why: Severe hypertension, seizure, altered mental status, and pulmonary edema are immediately life-threatening; anchoring on infection or seizure alone risks delayed control of the physiologic drivers.
After initial stabilization, CT head shows no hemorrhage. CT angiography demonstrates a cervical internal carotid artery dissection. She remains encephalopathic, and lumbar puncture is deferred because of the acute intracranial vascular process. Blood cultures are obtained, and empiric treatment for a serious infection is started because of persistent fever. Her oxygenation worsens despite noninvasive support, and she requires intubation with manual in-line stabilization because of persistent neck pain and concern for cervical injury after the seizure-related fall.
Committing question: What airway and neurologic priorities now dominate?
Expert move: Proceed with a controlled intubation while maintaining cervical-spine precautions, continue careful blood-pressure management, and involve neurology, critical care, obstetrics, and infectious-disease specialists.
Why: Intubation is indicated for worsening oxygenation and encephalopathy, but cervical artery dissection and possible cervical trauma make both hemodynamic surges and neck movement hazardous.
On ICU day 2, she develops worsening thrombocytopenia, renal dysfunction, and abdominal distention. Diagnostic paracentesis is performed because she has new ascites and persistent fever; the fluid is concerning for spontaneous bacterial peritonitis. Her blood pressure is now controlled, but she remains weak with poor respiratory effort after sedation is lightened.
Committing question: How should the new abdominal and neuromuscular findings be prioritized?
Expert move: Treat suspected spontaneous bacterial peritonitis promptly after paracentesis, reassess for multisystem infection and organ failure, and evaluate the weakness for a neuromuscular process while avoiding premature extubation.
Why: Cirrhotic or critically ill patients can develop SBP with subtle abdominal findings, while inadequate respiratory strength may reflect a neurologic or neuromuscular disorder and creates extubation risk.
Board Question
Which of the following is the best next step when the patient’s oxygenation worsens and she becomes encephalopathic despite noninvasive support? -
- AContinue noninvasive ventilation and observe for improvement -
- BPerform lumbar puncture before securing the airway -
- CIntubate with cervical-spine precautions and continue controlled blood-pressure management -
- DGive a large crystalloid bolus based solely on the IVC finding
Reveal answer
Correct: C
Intubate with cervical-spine precautions and continue controlled blood-pressure management.
Explanation: Worsening hypoxemia and encephalopathy are indications for definitive airway control. Her cervical artery dissection, neck pain, and possible trauma require cervical-spine precautions, while severe hypertension and neurologic injury make hemodynamic control essential. A large fluid bolus could worsen
pulmonary edema, and lumbar puncture should not delay airway stabilization or proceed without addressing the acute intracranial vascular process.
