MRCP2-4273
A 32-year-old male presents to the emergency department with a 1-day history of dyspnoea, dry cough, and palpitations. On examination, his temperature is 37.3ÂșC, respiratory rate is 28 breaths per minute, and oxygen saturation is 94% on room air. Blood pressure is 125/80 mmHg with a heart rate of 100 bpm. Reduced air entry in the right lower zone is noted on auscultation, and a chest radiograph confirms a right pneumothorax. A thoracostomy tube is immediately placed on the right side.
During the morning ward round, 3 days later, it is observed that there is an air leak of 50cc while checking the chest drain. A repeat chest radiograph shows that the right pneumothorax is still present.
What is the most appropriate next step in managing this patient?
