触电时如何急救?
若伤者神志清醒,呼吸心跳均自主,应让伤者就地平卧,严密观察,暂时不要站立或走动,防止继发休克或心衰。
1.关掉电闸,切断电源,然后施救。无法关断电源时,可以用木棒、竹杆等将电线挑离触电者身体。如挑不开电线或其他致触电的带电电器,应用干的绳子套住触电者拖离,使其脱离电流。救援者最好戴上橡皮手套,穿橡胶运动鞋等。切忌用手去拉触电者,不能因救人心切而忘了自身安全。
2.若伤者神志清醒,呼吸心跳均自主,应让伤者就地平卧,严密观察,暂时不要站立或走动,防止继发休克或心衰。
3.伤者丧失意识时要立即叫救护车,并尝试唤醒伤者。呼吸停止,心搏存在者,就地平卧解松衣扣,通畅气道,立即口对口人工呼吸。心搏停止,呼吸存在者,应立即作胸外心脏按压。
4.若发现其心跳呼吸已经停止,应立即进行口对口人工呼吸和胸外心脏按摩等复苏措施(少数已证实被电死者除外),一般抢救时间不得少于60-90分钟。直到使触电者恢复呼吸、心跳,或确诊已无生还希望时为止。现场抢救最好能两人分别施行口对口人工呼吸及胸外心脏按压,以1:5的比例进行,即人工呼吸1次,心脏按压5次。如现场抢救仅有1人,用15:2的比例进行胸外心脏按压和人工呼吸,即先作胸外心脏按压15次,再口对口人工呼吸2次,如此交替进行,抢救一定要坚持到底。
注意:
1.碰到闪电打雷时,要迅速到就近的建筑物内躲避。在野外无处躲避时,要将手表、眼镜等金属物品摘掉,找低洼处伏倒躲避,千万不要在大树下躲避。不要站在高墙上、树木下、电杆旁或天线附近。
2.处理电击伤时,应注意有无其他损伤。如触电后弹离电源或自高空跌下,常并发颅脑外伤、血气胸、内脏破裂、四肢和骨盆骨折等。
3.对电灼伤的伤口或创面不要用油膏或不干净的敷料包敷,而用干净的敷料包扎,或送医院后待医生处理。
4.现场抢救中,不要随意移动伤员,若确需移动时,抢救中断时间不应超过30秒。移动伤员或将其送医院,除应使伤员平躺在担架上并在背部垫以平硬阔木板外,应继续抢救,心跳呼吸停止者要继续人工呼吸和胸外心脏按压,在医院医务人员未接替前救治不能中止。
