If the air leakage is serious, the lung tissue gap may also need to be re-surgically sutured. 2. Drug treatment: patients with pulmonary nodule postoperative air leakage, if the combination of pain and discomfort, under the guidance of the doctor should take analgesic drugs, such as ibuprofen, etc.; if the combination of infection, also need active anti-infective treatment, such as oral antibiotics such as cefuroxime sodium.
