Dealing with chemical food poisoning, the first thing is to monitor the patient’s blood pressure, respiration, heart rate and oxygen saturation stability, stabilize the patient’s respiration and blood pressure. Breathing is not good, give oxygen, on the respiratory stimulant or endotracheal intubation on the ventilator; blood pressure is low, rapid rehydration, not up pressure medication; cardiac arrest should be immediately cardiopulmonary resuscitation; if the patient convulsions, with anti-convulsive medication; if the patient’s brain edema, high intracerebral pressure, the use of dehydration to lower brain pressure medication. Secondly, if there is a special antidote, the drug is used as soon as possible after getting it. In addition, it is also necessary to completely remove the poison, can be induced by vomiting, gastric lavage, adsorption, catheterization, enema methods to minimize the absorption of poison into the blood. Those that have been absorbed into the bloodstream can be rapidly rehydrated and diurezed, and in severe cases, blood purification should be performed to promote excretion. In addition, it is necessary to correct the disturbance of water, electrolyte, acid-base balance, and maintain the function of each organ.
