A 68-year-old man is brought to the emergency department by emergency medical services due to sudden-onset, severe shortness of breath. He has a history of ischemic cardiomyopathy with a known left ventricular ejection fraction of . Upon arrival, the patient is lethargic, diaphoretic, and using accessory muscles of respiration. His blood pressure is mm Hg, heart rate is /min, respiratory rate is /min, and oxygen saturation is on room air. Physical examination reveals cool, mottled extremities and prominent jugular venous distention. Auscultation of the lungs demonstrates coarse crackles in all lung fields. Which of the following is the most appropriate initial step in the stabilization of this patient?
- Endotracheal intubationCevap
- BInitiation of noninvasive positive-pressure ventilation
- CAdministration of intravenous furosemide
- DInitiation of an intravenous dobutamine infusion
- EAcquisition of a comprehensive transthoracic echocardiogram
Cevap
Endotracheal intubation is the most appropriate initial step to stabilize this patient's airway and breathing.
This patient is presenting with acute decompensated heart failure and cardiogenic shock, characterized by severe hypotension, cool and mottled extremities, and altered mental status. The initial stabilization of any critically ill patient must follow the ABCs (Airway, Breathing, Circulation). This patient is lethargic, hypoxic, and showing signs of impending respiratory failure (accessory muscle use, severe tachypnea). Endotracheal intubation is the most appropriate initial step to protect the airway, ensure adequate oxygenation, and decrease the work of breathing. Reducing the work of breathing is particularly critical in cardiogenic shock, as respiratory muscles can consume a massive amount of cardiac output during severe distress. Once the airway and breathing are secured, circulatory support (e.g., inotropes, vasopressors) can be safely initiated.

Anahtar Kavram
In patients presenting with cardiogenic shock and acute pulmonary edema, definitive airway management (endotracheal intubation) takes precedence when there is altered mental status, severe hemodynamic instability, or impending respiratory failure.
