Chills, fever, shock, and subcutaneous emphysema are characteristic of which condition?

• A. Acute Mediastinitis
• B. Acute Respiratory Distress Syndrome
• C. Pneumonia
• D. Pulmonary Embolism

Answer: (A)

Acute mediastinitis is suggested by a combination of systemic infection signs and air in the mediastinum that can track into the subcutaneous tissues. Chills and fever point to sepsis, and shock indicates a severe infection, while subcutaneous emphysema arises when air from the mediastinal or airway structures leaks into soft tissues. This pattern is classic after esophageal perforation or post-surgical sternotomy infection, where the infected mediastinal space can become cavitated with gas and enable air to dissect under the skin. Other conditions don't usually present with subcutaneous emphysema alongside fever, chills, and shock. Pneumonia mainly involves the lungs without mediastinal air leakage. ARDS centers on diffuse lung injury and hypoxemia rather than tissue air dissection. Pulmonary embolism can cause chest pain and shock but not typically subcutaneous emphysema or the same infection-prone presentation.
