Case Report: Treatment of Severe Subcutaneous Emphysema With a Negative Pressure Wound Therapy Dressing

OBJECTIVE This article describes a patient who developed severe subcutaneous emphysema and a persistent air leak after several attempts at needle thoracostomy for what was thought to be a tension pneumothorax. Subcutaneous emphysema was effectively treated with a topical negative pressure wound therapy dressing applied to a typical subfacial "blowhole" incision. This article aims to describe and contextualize the use of negative pressure wound therapy within the existing treatment options for subcutaneous emphysema. METHODS A case report of the clinical course and technique was drafted, and the relevant literature in PubMed was reviewed. RESULTS The level of subcutaneous emphysema decreased significantly within 48 hours of negative pressure wound therapy as confirmed with physical examination and computed tomography scans. Negative pressure wound therapy for subcutaneous emphysema has not been previously described in the literature. CONCLUSIONS Negative pressure wound therapy applied over subfascial incisions is a novel technique that effectively and rapidly controlled massive subcutaneous emphysema and persistent air leak. This technique may be efficacious in other cases of subcutaneous emphysema.
