氟里昂(Freon),系六氟乙烷,含两个碳的氟化物易挥发。通常用做致冷剂、发射剂、气溶胶。其分子量为138.01,沸点-79℃,熔点-94℃,室温下呈气态。吸入高浓度氟里昂,可引起肺部刺激症,心律失常,心肌收缩功能降低,以及中枢神经抑郁症。液态氟里昂,可致皮肤冻伤。美国Oregon卫生科学研究院Goetting医师等报道了手部氟里昂注入性损伤4例。4例均为制鞋工人。工人在制做运动鞋鞋底气垫时,左手握往鞋底中的小塑料袋,右手持针向袋内注入氟里昂。操作时,不慎针刺手都,手部注入氟里昂引起手损伤。病例1:患者,男性,39岁。因制做运动鞋鞋底气垫,手部不慎被针刺注入氟里昂后,左食指肿胀18小 Freon, a hexafluoroethane, two-carbon fluoride is volatile. Commonly used as a refrigerant, propellant, aerosol. The molecular weight of 138.01, boiling point of -79 ℃, melting point -94 ℃, was gaseous at room temperature. Inhalation of Freon at high concentrations can cause pulmonary irritation, arrhythmia, decreased myocardial contractility, and central nervous depression. Liquid freon, can cause skin frostbite. Goetting physicians from Oregon Institute of Health Sciences in the United States reported 4 cases of Freon injection injury in the hand. 4 cases are shoe-making workers. Workers in the manufacture of sports shoes soles cushion, the left hand to hold the small plastic bag in the sole, the right needle into the bag to Freon. Operation, accidentally acupuncture hands, hand injection Freon caused hand injury. Case 1: Patient, male, 39 years old. Due to the manufacture of sports shoes soles cushion, hand accidentally acupuncture injection Freon, the left index finger swelling 18 small
