央视网消息：近日，全国多地开启"炙烤模式"。持续高温环境下，有一种危险悄然逼近——"热中风"。"中风"是卒中的俗称，而"热 中风"是指在高温天气，也就是气温超过32摄氏度下出现的卒中事件。"热中风"有什么症状？和普通中暑有什么区别？ 发生"热中风"时，可能会出现头晕、头痛、恶心呕吐等症状。这些症状和中暑有相似之处，该如何区分"热中风"和中暑？ 研究表明，极端高温天气和极寒天气都会增加脑血管疾病的发生风险。根据卒中引起的出血或缺血的异常状态，一般可将其分为缺 血性卒中和出血性卒中，"热中风"中的大多数属于缺血性卒中。 发生机制：高温导致的血液血管血压变化 在炎热天气下，人体出汗增多，血管扩张明显，如果水分补充不及时，容易导致血容量不足，在血液浓缩的情况下，血小板易于聚 集，就会增加血栓的形成风险。而高温容易导致人心情烦躁、易怒，从而引发血压波动，也可能诱发卒中。 专家介绍，夏季频繁进出空调房间或让冷风直吹头面部，会使血管迅速收缩或扩张。老年人的血管弹性较差，受冷刺激易引发血管 痉挛。这些因素相互叠加，导致高温天气成为卒中发作的重要诱因。 区分"热中风"和中暑：局部神经功能受损 中暑主要是体温调节功能紊乱，最早症 ...

Core Viewpoint - The article emphasizes the increasing cases of heat stroke, particularly heat stroke, due to prolonged high temperatures, highlighting its severe consequences and high mortality rate [1][3]. Group 1: Health Risks and Symptoms - Heat stroke can lead to multi-organ dysfunction and failure, with a mortality rate ranging from 14% to 65% [3]. - Initial symptoms of heat stroke include dizziness, nausea, vomiting, and excessive sweating, which can escalate to severe conditions like unconsciousness and multi-organ damage if not treated promptly [5][7]. - High-risk groups include the elderly, infants, and individuals with chronic diseases, as well as those engaged in strenuous physical activities without adequate cooling [7][8]. Group 2: Prevention and Response - It is crucial to move individuals showing signs of heat stroke to cooler environments and implement cooling measures immediately [8]. - Common misconceptions include using alcohol for cooling, which can harm sensitive skin and lead to alcohol absorption issues; instead, using lukewarm water for wet compresses is recommended [8][12]. - Self-medication with cooling drugs is less effective than hydration; drinking water or saline solutions is prioritized for recovery [10][12].

Group 1 - The incidence of heat stroke cases is increasing due to prolonged high temperatures, with a high mortality rate ranging from 14% to 65% if not treated promptly [1][6] - Symptoms of heat stroke can escalate rapidly from mild heat exhaustion to severe heat stroke within a few hours, necessitating immediate medical attention to prevent irreversible damage [1][3] - High-risk groups for heat stroke include elderly individuals, infants, and those with chronic health conditions, as well as people engaged in outdoor work or strenuous physical activities [6][4] Group 2 - Enclosed environments, such as poorly ventilated spaces, can significantly increase the risk of heat stroke, particularly among the elderly who may avoid using air conditioning [4][3] - Common scenarios leading to heat stroke include prolonged cooking in non-air-conditioned kitchens, extended stays in indoor hot springs, and postpartum recovery without proper ventilation [4][6] - Immediate cooling measures and hydration are critical for individuals showing symptoms of heat stroke, as self-medication with cooling drugs is often ineffective [7][6]

Group 1: Heatstroke Incidents - There has been a noticeable rise in emergency calls related to heatstroke, especially among delivery workers and sanitation workers [1]. - Heatstroke can occur even in indoor environments with high humidity, emphasizing the need for awareness among the elderly who may not recognize the symptoms [3][4]. Group 2: Cardiovascular Disease Surge - The number of patients with cardiovascular diseases has increased by approximately one-third since July, with cases of acute heart attacks rising significantly [5]. - High temperatures can lead to blood thickening and increased risks of heart and brain attacks due to emotional fluctuations and blood pressure instability [6][8]. Group 3: Recommendations for Safety - Experts recommend maintaining hydration, managing emotional stress, and avoiding drastic temperature changes to mitigate health risks during high temperatures [9]. - For outdoor sports enthusiasts, it is advised to adjust exercise plans, avoid outdoor activities during peak heat hours, and stay hydrated with electrolyte drinks [10].

Group 2: Health Risks and Recommendations - High temperatures can disrupt the human body's temperature regulation system, potentially leading to heatstroke, especially in conditions of low wind speed and high humidity [2]. - When temperatures exceed 32°C with humidity over 70%, the body's perceived temperature can rise by 10°C, increasing the risk of heat-related illnesses [2]. - Public health recommendations include avoiding prolonged outdoor activities during high-temperature periods, implementing effective sun protection measures for outdoor workers, and ensuring adequate hydration [2].

近日，各地出现多起因热射病致死案例。人们常将"中暑"与头晕乏力画等号，认为多喝水休息一下 即可缓解。殊不知热射病是致死率极高的医学急症，能在数小时内引发多器官衰竭！ 切勿轻视任何中暑症状！解放军总医院重症医学专家张玉想警示，公众存在严重认知误区——"不 就是中暑？还能死人？"这种轻视极易延误识别，错过"黄金救治期"，导致死亡或永久残疾。 如何区分中暑和热射病 全军热射病防治专家组组长、解放军总医院海南医院首席专家宋青提到，自我判断是否热射病要关 注4个预警信号：烫、晕、晃、乱。烫，指的是自己感觉由内而外地发烫；晕，是感到头晕目眩；晃， 指患者行走不稳，觉得十分疲劳，连迈腿都费劲（在旁人看来患者走路如同醉酒）；乱，患者面部潮红 或发白，发生恶心呕吐、心慌气短、腹痛腹泻等症状，说明此时体内各个器官开始出现热射病表现。旁 人如果识别出此人患上热射病，应立刻进行现场急救，并送患者入院救治。 宋青说："热射病损伤的严重程度主要取决于高温的峰值和持续时间。就比如我们煮一个鸡蛋，刚 放进沸水里我们就立刻关火捞出来，打开鸡蛋，里面依旧是生的；但如果已经煮了三五分钟再捞出来， 鸡蛋里面就已经熟了，凝固了，人体也是一样。人体温度 ...

上午9点，合肥120急救中心指挥大厅迎来呼入高峰。大屏幕上，接听量、出车数急速跳动。调度员冷静询问症状、地址后，一辆辆救护车 迅速驶向现场。 央视网消息：高温天气持续，最近，医院里热射病的病例增多。专家提醒，热射病就是严重的中暑，死亡率高，出现中暑症状后一定不能 忽视。 几天前，山东淄博市70岁的王女士因为意识障碍被120救护车送至淄博市中心医院急诊科。医务人员发现王女士体温高达40.3摄氏度，医 务人员迅速为王女士使用冰毯及冰帽物理降温，并积极给予补液等治疗，王女士体温下降后神志逐渐转清，后转入病房继续治疗，目前已康复 出院。 安徽合肥：中暑病例增加 120专线呼入量增加近两成 记者从安徽合肥急救中心获悉，近段时间随着热射病等中暑病例增加，120急救专线日均来电近1500个，较本轮高温前增加近两成。 数据显示，过去10天伴随气温飙升，中暑相关急救呼救明显增多，高发时段集中在中午至傍晚，症状多为头晕、恶心、呕吐甚至意识不 清。值得注意的是，居家老人中暑的病例也不少。有医生介绍，因老年人身体机能减退、体温调节功能差，需要特别注意。即使在家中的时 候，也要适当开空调。此外，儿童因新陈代谢快，但体温调节中枢未发育成 ...
