title: Freon injection injury to the hand. A report of four cases.
abstract: During a 6-month period, the poison center was consulted on three occasions for advice regarding accidental injection of hexafluorethane (Freon) used in the manufacturing process of athletic shoes. A fourth case was later identified after consulting physicians near the manufacturing facility. Little information exists in the medical literature concerning injection of freon or other volatile substances. In each of these cases, workers inadvertently injected concentrated hexafluorethane into a finger while holding the shoe component and attempting to inject hexafluorethane. Each case presented with edema, limitation of motion, and crepitation. Hand roentgenogram revealed subcutaneous gas. Treatment was nonsurgical, consisting of splinting, tetanus immunization, and antibiotics. Rapid resolution of symptoms occurred in all four cases. Hexafluorethane is relatively inert when injected and has low toxicity. However, potential rapid expansion warrants observation for pressure injury.
