非冰凍冷傷害 — (NFCI) 是一個通用術語,包括戰壕足及其在航海中對應的浸水足。
遭受 NFCI 的足部(有時也包括手部)最初會發白且麻木(圖 1),但之後會變紅、水腫且極度疼痛。在嚴重的情況下,肢體可出現出血性大皰和組織壞死。
trench foot 「戰壕足」一詞最早出現在第一次世界大戰期間 [ 1 ],儘管這種疾病在 100 多年前拿破崙在俄國災難性的冬季戰役中就已被認識到 [ 2 ]。浸泡足是一種相同的損傷,在第二次世界大戰期間首次被描述為在救生艇上遇難的水手身上[ 3 ]。當水手被迫跪在或坐在濕船的地板或救生艇底部時,膝蓋或臀部會受到影響。受 NFCI 影響的主要平民群體是冷水中遇難的船員和野外事故(如飛機失事和沈船)的倖存者,他們必須穿著濕鞋和衣服在寒冷潮濕的環境中行走。徒步旅行者和無家可歸的人也有 NFCI 的風險。
已描述了許多其他與NFCI相關或相同的疾病。一種可能相同的疾病是「海靴足」或「橋足」[ 4 ]。第二次世界大戰期間,水手們連續穿著橡膠海靴超過4小時保持相對靜止不動時出現了這種疾病[ 5 ]。一名潛水員在暴露於冷水(6°C)後,手部也出現了這種損傷[ 6 ]。
一種相關但不同的疾病是避難所足(或避難所肢)[ 4 ]。第二次世界大戰期間,人們整夜坐在寒冷的防空洞裡,既不移動也不抬高雙腿,也出現了這種疾病[ 7 ]。如果膕窩內或附近的區域靠在躺椅的橫桿上,則嚴重程度會更嚴重,這表示這些損傷是周邊神經病變。
溫水浸泡損傷 Warm water immersion injuries
與凍傷和NFCI等類似疾病一樣,WWIF及其預防措施可能會被遺忘,直到復發。 1994 年,對一個在夏威夷多雨山區接受訓練的 400 名美國步兵營進行了一項回顧性調查,報告稱,在 176 名返回問卷的士兵中,有 149 例患有 WWIF[ 12 ]。

Nonfreezing cold injury — Nonfreezing cold injury (NFCI) is a general term that includes trench foot and its nautical equivalent immersion foot. NFCI involves injury to the soft tissues, nerves, and vasculature of distal extremities from prolonged exposure to wet, cold (but nonfreezing; generally 0 to 15°C or 32 to 59°F) conditions. Most often feet are involved, but the condition can affect any dependent body part or the hands. In this topic, we will refer to all such conditions as NFCI. Frostbite is distinguished from NFCI because it involves exposure to freezing temperatures, as implied by the name. (See "Frostbite: Acute care and prevention".)
Feet and occasionally hands that sustain NFCI are initially white and numb (picture 1), but later become red, edematous, and extremely painful. In severe cases, the extremity can develop hemorrhagic bullae and tissue necrosis. (See 'Nonfreezing cold injury' below.)
The term trench foot was first used during World War I [1], although the condition had been recognized over 100 years earlier during Napoleon's disastrous winter campaign in Russia in 1812 [2]. Immersion foot, an identical injury, was first described during World War II in shipwrecked sailors aboard life boats [3]. When sailors are forced to kneel or sit on the floorboards of a wet boat or the bottom of a lifeboat, the knees or buttocks can be affected. The main civilian groups afflicted with NFCI are shipwrecked crews in cold waters and survivors of wilderness accidents such as plane crashes and capsized boats who must walk in a cold, wet environment with wet shoes and clothing. Hikers and people experiencing homelessness are also at risk for NFCI.
A number of other conditions either related or identical to NFCI have been described. One likely identical condition is "sea boot foot" or "bridge foot" [4]. This condition was described during World War II in sailors who remained relatively immobile for over four hours at a time while wearing rubber sea boots continuously [5]. The injury has been described in the hand of a diver who was exposed to cold (6°C) water [6].
One related but distinct condition is shelter foot (or shelter limb) [4]. This condition was described during World War II in people who spent nights sitting in cold air-raid shelters without moving or elevating their legs [7]. The severity was worse if the area in or near the popliteal fossa was resting against the cross bar of a deck chair, suggesting that these injuries were peripheral neuropathies.
Warm water immersion injuries
●Warm water immersion foot (WWIF) – This is a transient syndrome first described in soldiers in Vietnam. It manifests as painful, white, wrinkled soles of the feet due to immersion in warm water (approximately 15 to 32°C; 59 to 90°F) for up to 72 hours [8]. It has also been called paddy-field foot and, incorrectly and confusingly, "tropical immersion foot," which is a more severe condition [9]. Most patients with WWIF recover completely in one to three days with drying and elevation of the feet [10]. Warm water immersion hand has also been described [11].
As with similar conditions such as frostbite and NFCI, WWIF and measures for its prevention may be forgotten until it recurs. A retrospective survey of a battalion of 400 United States infantry soldiers who trained in rainy mountains in Hawaii in 1994 reported 149 cases of WWIF among the 176 soldiers who returned the questionnaire [12].
●Tropical immersion foot (TIF) – This was also described in soldiers in Vietnam, is a more severe condition than WWIF. TIF causes inability to walk because of painful, swollen feet after immersion in warm water (22 to 32°C; 72 to 90°F) for over 72 hours [10]. TIF is characterized by symmetrical redness, edema, and tenderness of the skin of the ankles and the dorsa of the feet (picture 2 and picture 3 and picture 4 and picture 5). Treatment includes drying the feet followed by bed rest and elevation of the feet. Complete recovery usually takes four to five days, although severely affected patients sometimes require as long as 10 to 12 days. There are no known sequelae.
●Jungle foot – This is sometimes referred to as "tropical jungle foot," "jungle rot," or "paddy foot," is a poorly defined condition seen in wars in Vietnam. Most, but not all, reports of jungle foot refer to TIF [10].
Other cold-related conditions
●Frostnip – Cold-induced, severe vasoconstriction of the skin with frost (ice crystals) on the surface of the skin. There is no ice in the tissue. Frostnip resolves after rewarming without permanent tissue damage.
●Frostbite ‒ Frostbite is a localized, cold-induced injury due to freezing of tissue (picture 6 and picture 7).
●Pernio or chilblains ‒ Pernio, or chilblains, is a condition characterized by localized inflammatory lesions. Chilblains can result from acute or repetitive exposure to cold above the freezing point. In most, but not all, cases, the exposure involves damp cold. Lesions are red or purple, often nodular, and may be very painful or pruritic (picture 8 and picture 9 and picture 10 and picture 11 and picture 12).
●Cold urticaria ‒ Cold urticaria, or cold contact urticaria, is a physical urticaria induced by contact with cold (picture 13). Cold urticaria is characterized by hives or angioedema.
●Cryoprecipitation ‒ Cryoprecipitation refers to precipitation of blood proteins at temperatures below 37°C. There are two types of cryoprecipitation: cryoglobulinemia and cryofibrinogenemia. Cryoglobulinemia refers to precipitation of blood proteins from serum and plasma. People with cryoglobulinemia are asymptomatic, but some may develop hyperviscosity or thrombosis. Cryofibrinogenemia refers to precipitation of proteins from plasma. Most people with cryofibrinogenemia are asymptomatic, but some may develop thrombosis. (See "Overview of cryoglobulins and cryoglobulinemia" and "Disorders of fibrinogen", section on 'Cryofibrinogenemia'.)
●Raynaud phenomenon ‒ Raynaud phenomenon is an exaggerated vascular response to cold temperature or emotional stress characterized by well-demarcated pallor, cyanosis, or both of the distal parts of digits (picture 14). (See "Clinical manifestations and diagnosis of Raynaud phenomenon".)
