游泳后可能干性溺水,没有症状却可致命

流言于一个普通的夏日在游泳池游过之后,一位澳大利亚母亲发现她的儿子的行为出现了某些异常。X光显示孩子经历了干性溺水,如果不立即救治会致命。这种溺水很罕见,只吸入6大汤匙的水可能就会出现。救治的关键在于了解并认识这种情况的症状:行为异常、疲劳、嗜睡、咳嗽、呼吸急促及脸色苍白。

真相流言搞混了干性溺水和迟发性溺水的,Secondary drowning 是迟发性溺死的一种分支,导致生命危险主要的原因是肺部的气体交换受阻,肺泡功能障碍,肺泡表面重要的表面活性剂流失,这种情况并不太常见。​

论证

干性溺水(Dry drowning)的重点是喉部痉挛造成急性窒息,因为气道的开口被封闭了,所以肺内可能会几乎没有什么进水。迟发性溺水(死)(Delayed drowning)则是在吸入水之后经过一段时间才发生的,人在溺水的当时没有死亡,而是在溺水后的24小时内死亡,就可以被定义为迟发型溺死,其原因多为继发性肺水肿、支气管炎或肺脓肿等。

Secondary drowning 是迟发性溺死的一种分支情况,一般可在溺水后12-72小时(显然已经超过了24小时的限定)出现,它并不等于迟发性溺死本身。它的名字很直白,就是二次溺死/继发性溺死,是由延迟性的肺水肿导致的在貌似康复后的溺死情况。

为什么会出现这种情况?有研究显示,这种迟发溺水(secondary submersion)导致生命危险主要的原因是肺部的气体交换受阻,肺泡功能障碍,肺泡表面重要的表面活性剂流失。这里提到这种情况是不太常见的,在所有的溺水相关事件中占了2~5%。

这个问题在孩子身上更值得警惕,但成年人也不是没有可能。孩子玩水的时候需要注意看护,然后一些疾病的患者也要留意,醉酒时也不要游泳。这种迟发溺水的症状包括呼吸困难、胸痛、咳嗽等等,如果有异常需要尽快就医,争取时间对救治很重要。另外对发生溺水之后看起来恢复了的人也要留意观察。

    范县人民医院温馨提醒!!!看到的请复制下去,小朋友只要溺水不超过一个小时 就可以救活!从河里救出两名溺水幼儿。孩子已没有呼吸, 村民就用当地特有的急救法,攥着孩子双脚,倒背着孩子跑步。几分钟后,小男孩吐出几口水来,哇地一声哭了。又跑了起码十分钟,小女孩也从死神的手中被拉扯了回来。暑假到了,不知多少孩子要下水游泳,看到的请顶下去,说不定可以救很多人。 医师强调,如果每个收到这条信息的人,都能够带给其他人,肯定至少有一条生命将会被挽救回来,我已经做了我的部分了!所以现在你有两个选择: 1. 无视 2. 让更多人看到 愿所有人安好
