[Preventive strategy of economy class syndrome].

Economy class syndrome (ECS) refers to a series of symptoms, such as lower limb swelling, chest pain, dyspnea, and sudden death, that occur during or after a long-distance flight. Its essence is venous thromboembolism. ECS, as a preventable syndrome, is one of the causes of sudden death in long-distance travelers. Medical assistance to the African region is a very important diplomatic matter of China. It often takes medical workers more than 10 hours of long-distance flight to reach the recipient country. Therefore, it is essential to improve the understanding of ECS and corresponding prevention strategies among the long-distance traveling people including medical workers assisting Africa, which could guarantee their health and ensure the smooth implementation of the work of assisting Africa.经济舱综合征（ECS）是指长途旅行者在飞行途中或飞行后一段时间内出现下肢肿胀、胸痛、呼吸困难、甚至猝死等一系列症状，其本质为静脉血栓栓塞症。ECS是长途旅行者发生猝死的原因之一，是一种可以预防的综合征。对非洲地区进行医疗援助是我国非常重要的外交事宜。援非医务人员往往需要超过10 h的长途飞行才能到达受援国。因此，提高援非医务人员为代表的长途旅行人群对ECS及其预防策略的认识至关重要，这有利于保障援非医务人员自身健康及顺利开展援非工作。.
