摘要

以前的研究表明,EpiPen® 自动注射器在摄氏零下 25 度的环境中最多可以正常启动五次,但有关其他品牌肾上腺素自动注射器冷冻后性能的数据以前尚未公布。此外,极地医疗人员所经历的条件可能比这还要冷得多,肾上腺素自动注射器在更极端的冻融循环后的性能仍未得到描述。南极洲和英国的研究人员对 EpiPen® 和 Jext® 两种品牌的肾上腺素自动注射器进行了实验室测试(每种设备各 12 支)。单次冻融循环包括将设备冷冻到零下 80 摄氏度,然后让其恢复到室温。装置分别经过 0、1、5 或 15 次冻融循环。然后测量每个装置在激活时喷出的液体质量。测试组之间喷出液体的质量没有明显差异。多次-80°C冻融循环不太可能对 EpiPen® 和 EpiPen® 自动注射器排出的肾上腺素溶液量产生重大影响。这一初步发现有助于进一步研究肾上腺素自动注射器暴露于极低温度后的安全性和有效性。这些信息对于未来极地医疗人员在极端环境中规划和提供医疗服务非常有价值。

Repeated freezing to very low temperatures does not impact the amount ejected from EpiPen® and Jext® adrenaline autoinjectors.

It has previously been shown that EpiPen® autoinjectors are likely to activate normally following up to five excursions to -25°C but data about the post-freezing performance of other brands of adrenaline autoinjectors has not previously been published. Additionally, conditions experienced by polar medics may be substantially colder than this and the performance of adrenaline autoinjectors following more extreme freeze-thaw cycles remains uncharacterised. Investigators in Antarctica and the United Kingdom performed laboratory testing on two brands of adrenaline autoinjector, EpiPen® and Jext® (12 devices of each type). A single freeze-thaw cycle involved freezing the device to -80°C then allowing it to come to room temperature. Devices were exposed to 0, 1, 5 or 15 freeze-thaw cycles. The mass of liquid ejected from each device, when activated, was then measured. No significant differences in the mass of the liquid ejected was found between the test groups. Multiple freeze-thaw cycles to -80°C are unlikely to significantly impact the amount of adrenaline solution expelled from EpiPen® and EpiPen® autoinjectors. This preliminary finding encourages further work investigating the safety and effectiveness of adrenaline autoinjectors after exposure to very low temperatures. This information would be valuable for future polar medics planning and delivering medical provision in extreme environments.

期刊介绍: The International Journal of Circumpolar Health is published by Taylor & Francis on behalf of the Circumpolar Health Research Network [CircHNet]. The journal follows the tradition initiated by its predecessor, Arctic Medical Research. The journal specializes in circumpolar health. It provides a forum for many disciplines, including the biomedical sciences, social sciences, and humanities as they relate to human health in high latitude environments. The journal has a particular interest in the health of indigenous peoples. It is a vehicle for dissemination and exchange of knowledge among researchers, policy makers, practitioners, and those they serve. International Journal of Circumpolar Health welcomes Original Research Articles, Review Articles, Short Communications, Book Reviews, Dissertation Summaries, History and Biography, Clinical Case Reports, Public Health Practice, Conference and Workshop Reports, and Letters to the Editor.
