title: Profile of acute mixed organophosphorus poisoning.
abstract: Organophosphorus (OP) pesticide self-poisoning is a major clinical and public health problem across much of rural Asia and responsible for two thirds of suicidal deaths. However, clinical reports or evidence for the management of mixed poisoning are lacking. Patients are often treated based on the type of symptoms they exhibit, and there are no specific guidelines available to treat mixed poisoning. In this case series, we report 3 acute OP poisoning cases with mixed poisons such as organochlorine, fungicide, copper sulfate, and kerosene. All 3 patients were treated successfully, with a greater focus on OP poisoning with pralidoxime and atropine infusion along with standard decontamination procedures. Because patients developed complications due to the concomitant poisons ingested, they were later treated symptomatically, and in one case, D-penicillamine was administered as antidote for copper poisoning. Mixed poisoning especially with OP compounds makes the diagnosis difficult because the clinical symptoms of OP predominate, whereas damage produced by other pesticides is late to develop and often neglected. Common treatment procedures are focused mainly on the OP poisoning ignoring the complications of other concomitant pesticides ingested. Treating physicians should be prepared and consider the possibility of mixed poisoning prevalent in that region before initiating therapy.
