在抢救有机磷农药中毒时,阿托品的应用一定要遵循“观察—分析—调整”的方针,即“在观察中使用,在使用中观察”,以及“早期、足量、反复”的给药原则,既要注意阿托品用量不足,又要防止过量中毒。大剂量阿托品是抢救重度有机磷中毒患者成功的关键。目前一般采用的阿托品量首剂:轻型1—3mg,中型4—8mg,重型9—12mg。试探性剂量:以中度中毒病人为例,按上述用量应为阿托品4—8mg,但可先用5mg一次静脉注射、然后观察3—5分钟,如瞳孔、颜面、心率躁动等情况无变化,可再静脉注射10mg,并在继续观察了3—5分钟,如上述指标变化不大,则继续注射15mg,再观察后,若出现瞳孔散大,心率加速,颜面潮红,轻度躁动等表 In the rescue of organophosphorus pesticide poisoning, the application of atropine must follow the “observation - analysis - adjustment” approach, namely “observed in use, observed in use”, and “early, adequate, repeated” principle of administration , It is necessary to pay attention to the lack of consumption of atropine, but also to prevent excessive poisoning. High-dose atropine is the key to the success of patients with severe organophosphate poisoning. Atropine currently used in the first dose: light 1-3mg, medium 4-8mg, heavy 9-12mg. Tentative dose: moderate poisoning patients, for example, according to the above dosage should be atropine 4-8mg, but can be a 5mg intravenous injection, and then observed for 3-5 minutes, such as the pupil, face, heart rate agitation and so on did not change, Can be intravenous injection of 10mg, and continue to observe the 3-5 minutes, such as the above indicators did not change much, then continue to inject 15mg, and then observed, if there mydriasis, accelerated heart rate, facial flushing, mild agitation and other
