To review our institution's experience with frostbite injury secondary to "salt and ice challenge" (SIC) participation.
We conducted a retrospective analysis of intentional freezing burns from 2012 to 2014. Demographics, depth and location of burn, total body surface area of burn, treatment, time to wound healing, length of stay, complications, and motives behind participation were analyzed.
Five patients were seen in the emergency department for intentional freezing burns that resulted from SIC (all females; mean age: 12.3 years; range age: 10.0-13.2 years). Mean total body surface area was 0.408%. Salt and ice was in contact with skin for >10 min for two patients, >20 min for two patients, and an unknown duration for one patient. Complications included pain and burn scar dyschromia. Four patients cited peer pressure and desire to replicate SIC as seen on the Internet as their motivation in attempting the challenge.
SIC has become a popular, self-harming behavior among youths. Increased public education, and provider and parent awareness of SIC are essential to address this public health concern.
回顾我院对因参与“盐冰挑战”（SIC）导致冻伤的治疗经验。
我们对2012年至2014年期间的故意冻伤进行了回顾性分析。分析了患者的人口统计学特征、烧伤深度和部位、烧伤总面积、治疗方法、伤口愈合时间、住院时间、并发症以及参与挑战的动机。
有5例因SIC导致故意冻伤的患者在急诊科就诊（均为女性；平均年龄：12.3岁；年龄范围：10.0 - 13.2岁）。平均烧伤总面积为0.408%。两名患者盐冰与皮肤接触超过10分钟，两名患者超过20分钟，一名患者接触时间不详。并发症包括疼痛和烧伤疤痕色素沉着异常。四名患者表示，同伴压力以及想模仿网上看到的SIC是他们尝试挑战的动机。
SIC已成为青少年中一种流行的自残行为。加强公众教育，提高医疗服务提供者和家长对SIC的认识，对于解决这一公共卫生问题至关重要。
