Meet the patient
A 24-year-old presents with a month of facial swelling worse in the morning, a night-time preference for sleeping propped on three pillows, and a wheeze that "asthma" treatment has not touched. The CT shows a large anterior mediastinal mass compressing the distal trachea to a slit. The registrar asks when he can come to theatre for a biopsy under general anaesthesia — and that is the most dangerous question on the ward round.[1]
The single decision that decides whether this patient lives is whether the airway and the great vessels need spontaneous ventilation to stay open. If they do, a routine RSI with full paralysis is the catastrophe: cannot ventilate, cannot intubate distal to a compression the tube cannot reach, and cardiovascular collapse from vascular compression that looks nothing like a difficult laryngoscopy.[2]
