We present here a case of non-freezing cold injury (NFCI) in a sport scuba diver. There are similarities between the presenting symptoms of NFCI and decompression sickness, e.g., pain and/or altered sensation in an extremity, often reported as numbness. In both conditions patients have been known to describe their lower limbs or feet as feeling woolly. Both conditions are the result of environmental exposure. Additionally, there are no good (high sensitivity and specificity) diagnostic tests for either condition. Diagnosis is made based on patient history, clinical presentation, and examination. NFCI is most frequently seen in military personnel, explorers, and the homeless. When affecting the feet of soldiers it is often referred to as "trench foot." Historically, NFCI has been and continues to be of critical importance in infantry warfare in cold and wet environments. A high priority should be given to prevention of NFCI during military operational planning. With the advent of so-called "technical diving" characterized by going deeper for longer (often in cold water) and adventure tourism, this extremely painful condition is likely to increase in prevalence. NFCI is treated symptomatically.
我们在此呈现一例职业水肺潜水员的非冻伤性冷损伤（NFCI）病例。NFCI的临床表现与减压病存在相似之处，例如肢体疼痛和/或感觉改变，常表现为麻木。在这两种情况下，患者都曾描述其下肢或足部有“毛茸茸”的感觉。这两种情况都是环境暴露的结果。此外，对于这两种情况，都没有很好的（高灵敏度和特异性）诊断测试。诊断基于患者病史、临床表现和检查。NFCI最常见于军事人员、探险者和无家可归者。当影响士兵的足部时，它常被称为“战壕足”。从历史上看，NFCI在寒冷潮湿环境中的步兵战争中一直且仍然至关重要。在军事行动规划中，应高度重视NFCI的预防。随着以更深、更长时间潜水（通常在冷水中）为特征的所谓“技术潜水”以及冒险旅游的出现，这种极其痛苦的病症患病率可能会上升。NFCI采用对症治疗。
