We have reported a case of severe frostbite due to direct exposure to liquid Freon gas (monochlorodifluoromethane), a fluorinated hydrocarbon widely used as refrigerants, propellants, and industrial solvents. The patient was treated for severe third- and fourth-degree frostbite to the hand. The severity of the injury was apparently the result of direct through-and-through injury from exposure to the liquid (boiling point -40.5 degrees C) and a possible systemic vasoconstrictive effect on arterial smooth muscle due to inhalation of Freon gas.
我们报告了一例因直接暴露于液态氟利昂气体（一氯二氟甲烷）而导致严重冻伤的病例。氟利昂是一种广泛用作制冷剂、推进剂和工业溶剂的碳氟化合物。该患者因手部严重的三度和四度冻伤接受治疗。损伤的严重程度显然是由于暴露于该液体（沸点为-40.5摄氏度）导致的直接贯通伤，以及吸入氟利昂气体可能对动脉平滑肌产生的全身血管收缩作用所致。
