Novel management of extensive subcutaneous emphysema in cardiac surgery: cases presentation

Subcutaneous emphysema occurs when air is trapped between subcutaneous tissues and manifests as sudden swelling, dysphonia, and sore throat. In many severe cases, subcutaneous emphysema causes dysphagia, pain, and breathing difficulty. The current study reports two cases of successful management of extensive subcutaneous emphysema after cardiac surgery.The first patient was a 60-year-old man with a history of coronary artery disease who underwent coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass. He was transferred to the intensive care unit (ICU) in good condition. Twelve hours after the surgery, he was extubated in a stable condition. On the second day after the surgery, his face, neck, and chest began to swell due to extensive subcutaneous emphysema, and he experienced decreased SPO2 and severe respiratory distress.The second patient was a 65-year-old woman with a history of myocardial infarction (MI) who had CABG off-pump surgery. After surgery, the patient was transferred to the ICU in a favorable and stable condition and was extubated 6 hours after the surgery. Her face, neck, and chest started swelling three days after the surgery, and she had severe respiratory distress and decreased blood saturation due to extensive subcutaneous emphysema.In both cases, despite conventional treatment, the patient's symptoms escalated despite re-intubation and mechanical ventilation.In the operating room, the chest tubes were removed, two new chest tubes were inserted, and the area damaged by the old tubes was repaired. Shortly after the insertion of the chest tubes, the patient's emphysema symptoms decreased significantly.
