This is an
airway emergency. Call emergency services / shift to ED or ICU immediately. Early expert airway management is needed, often intubation before swelling worsens; surgical airway may be required if intubation becomes impossible. Do
not delay for chest X-ray or assume it is pulmonary edema. PPD poisoning characteristically causes severe cervicofacial and upper-airway edema, with later rhabdomyolysis, hyperkalemia, and acute kidney injury, as described in this
clinical report.
Pulmonary edema or cardiac dysfunction can occur but is less typical. Check SpO₂, ECG, BP, ABG, bedside lung and cardiac ultrasound, chest X-ray, troponin/BNP as clinically appropriate. Sudden breathlessness with pink frothy sputum, diffuse lung crackles, high JVP, or B-lines may support pulmonary edema, but stridor plus cervicofacial swelling points to upper-airway obstruction.
