春雷隆隆和大家说说雷电对人体的伤害以及如何防止雷击
春季是雷电灾害的多发季节,每当雷雨之时,天空阴云密布,大雨滂沱,一道闪电划破长空,远处传来隐隐雷声。突然,抢救室的电话急促响起,某居民小区发现有一个人倒在泥泞的雨水中,生死不明。当我们的救护车到达现场,医护人员发现伤者的颜面和口唇已经青紫,瞳孔散大固定,动脉搏动消失,呼吸停止。伤者约20多岁,斜挎的书包内塞满考试试题和参考书,手中握着一部手机。手指有被烧焦的痕迹。由现场情景判断,伤者可能是被雷电击伤,心跳骤停。我们紧急做了现场心肺复苏,但因心跳骤停时间较长,抢救无济于事。
  雷电对人体可能造成的危害
  科学不发达的时代,人们充满对雷电的恐怖,认为是天神发怒,惩罚有罪之人。后来随着科学的发展,人们逐渐了解到雷电是一种自然现象。闪电就是巨大的电火花。人是导电体,若被雷电直接击中头部,并且通过躯体传到地面,可以使心脏和神经麻痹,这时心脏可能停止跳动,或者发生室颤,就是心跳极不规则,心脏不能有效地射血,被击者无脉搏、无血压;脑神经受损可直接抑制心跳和呼吸中枢,使人几分钟内死亡。此外,尽管没有被雷电直接击中,也会引起事故。这是由于人体距离雷击点很近时,一部分雷电电流可通过“跨步电压”进入人体。
  提醒各位雷雨天气要记住:
  ●雷电时首先关好门窗,防止雷电进屋。
  ●室内人员远离门窗、水管、煤气管等金属物体。
  ●雷电时忌用太阳能热水器洗澡。
  ●雷电时尽量不用电器,拔掉电源插头,防止雷电从电源入侵。
  ●雷电时不要打电话,尤其不能打手机,我们前去急救的那位青年学生很可能就是雷电时打手机而致命的。
  ●雷电时正在路上的行人,避雨时不能靠近孤立的高楼、电杆、烟囱、高耸的房角屋檐、广告牌、高塔等,更不能站在空旷的高地上或大树下躲雨,尽量寻找低洼地或者下蹲降低身体高度。
  ●立即停止室外游泳、划船、钓鱼等水上活动。
  ●如多人共处室外,相互间不要挤靠,以防被雷电击中后电流互相传导。
