敌敌畏系有机磷杀虫药,毒性大,主要是抑制胆硷脂酶的活性,致使体内乙酰胆硷不能分解成乙酸及胆硷而发生积蓄,导致胆硷能神经过度兴奋,若乙酰胆硷继续迅速积蓄,则很快转入抑制和衰竭。如果抢救不当,常造成病人死亡。我们今年共收治23例急性敌敌畏中毒。其中19例经口误服,4例由呼吸道吸入而发生过敏症状。经口服者按其临床表现的轻重,按内科手册的标准分度,轻度9例,中度6例,重度4例。男2例,女21例;19例是成人,最
Dichlorvos organophosphate pesticides, toxicity, mainly to inhibit the activity of cholinesterase, resulting in the body can not break down into acetylcholine and acetic acid and choline and the accumulation of savings, resulting in cholinergic nerve over-excited, if the acetylcholine continue Rapid accumulation, then quickly into inhibition and failure. If the rescue is not properly done, the patient often dies. We treated 23 cases of acute dichlorvos poisoning this year. Among them, 19 cases were orally taken orally and 4 cases were allergic to respiratory tract inhalation. According to the severity of oral clinical manifestations, according to the standard manual division, mild in 6 cases, moderate in 6 cases, severe in 4 cases. 2 males and 21 females; 19 were adults, most of them
