summary

Organophosphorus poisoning is what we call pesticide poisoning. Organophosphorus poisoning can be eaten, absorbed by the skin and other ways so that patients with organophosphorus poisoning of this disease. According to the amount of inhalation, the severity of the disease is also different. Let's talk about the symptoms of organophosphorus poisoning.

What are the symptoms of organophosphorus poisoning

First, the cholinergic receptors of parasympathetic nerve and sympathetic postganglionic fibers distributed in sweat glands were excited, showing that the secretion of glands increased, and the secretion of sweat, salivation and bronchus increased. The contraction of the iris sphincter causes the pupil to shrink and the gastrointestinal smooth muscle to excite, causing nausea, vomiting, diarrhea and abdominal pain.

Second: the cholinergic receptor at the motor neuromuscular junction is excited, showing muscle fibrillation or convulsion, and muscle weakness or paralysis in the late stage. The sympathetic preganglionic fibers and the sympathetic cholinergic receptors that innervate the adrenal medulla are excited. The symptoms of blood pressure rise, heart rate increase and body temperature rise can be seen. This is similar to the symptoms of nicotine poisoning, which is called nicotine like effect.

Third: the excitation of cholinergic receptors between the synapses of central nerve cells will produce the symptoms of central nervous system dysfunction. In the early stage of poisoning, dizziness, headache, speech disorder, unconsciousness and paroxysmal convulsions will appear. Organophosphorus poisoning can cause death due to respiratory central paralysis.

matters needing attention

Generally speaking, organophosphorus poisoning can be divided into mild, moderate and severe according to the degree of severity. According to the degree of these three kinds of poisoning, we should take different treatment measures.
