Frostbite injuries rarely occur in healthy Dutch persons. However, as the number of people engaging in winter and outdoor activities and travelling to high altitudes increases, the risk of frostbite also increases. Frostbite is a cold-induced injury which results from two processes: freezing and microvascular occlusion. Adequate first aid, which focuses on the prevention of refreezing and mechanical injury, and rapid rewarming together with the administration of ibuprofen, are of the greatest importance for limiting eventual tissue damage. Iloprost infusion and possibly (r)tPA are indicated if a patient presents within 24 hours after the tissue has thawed and the injury is such that severe morbidity can be expected. If the patient presents after this time period, hyperbaric oxygen therapy may be considered; however, the evidence available on this type of treatment is limited.
冻伤在健康的荷兰人中很少发生。然而,随着参与冬季和户外活动以及前往高海拔地区的人数增加,冻伤风险也随之上升。冻伤是一种由寒冷引起的损伤,它由两个过程导致:冻结和微血管阻塞。充分的急救,重点是预防再次冻结和机械损伤,以及快速复温并给予布洛芬,对于限制最终的组织损伤至关重要。如果患者在组织解冻后24小时内就诊且损伤可能导致严重发病,则可使用伊洛前列素输注,可能还需要使用(重组)组织型纤溶酶原激活剂。如果患者在此时间段之后就诊,则可考虑高压氧治疗;然而,关于这种治疗方法的现有证据有限。
