Management of Significant and Widespread, Acute Subcutaneous Emphysema: Should We Manage Surgically or Conservatively?

Here we present a case series of 4 patients, all with penetrating injuries to the upper limb resulting in widespread subcutaneous emphysema within 24 h of injury. Mean age was 33 years. All were fit and well, with the exception of one with type 1 diabetes, no cardiorespiratory compromise, and no significant derangement of laboratory investigations. X-ray studies showed widespread gas within the soft tissues. All were treated aggressively with immediate surgical fasciotomy of the upper limb, thorough debridement, and washout as required. Gram stains revealed pus cells (polymorphonuclear leucocytes) in all, but organisms in only one case (Gram-positive cocci and bacilli). Prolonged culture grew organisms in all. All patients had a second washout and closure plus 6 weeks of antibiotics. All survived and had fully functioning limbs. Why should an emergency physician be aware of this? We recommend having a low threshold for rapid referral to an appropriate surgical speciality, allowing prompt and radical surgical management of this type of presentation, even in the presence of a well patient.
