Is chlorine poisonous (causes, symptoms and preventive measures of chlorine poisoning)
(1) Toxicological effects
Chlorine is a yellow-green gas with strong * Sexual smell and choking stench. Many industries and pesticide production depend on chlorine. The harm of chlorine to the human body is mainly manifested as a strong stimulation of the upper respiratory tract mucosa, which can cause respiratory tract burns and acute pulmonary edema. , causing acute failure of lung and heart function.
(2) Symptoms of poisoning
Inhalation of high concentrations of chlorine, such as chlorine content per liter of air exceeding 2mg ~ 3mg, can lead to severe symptoms: dyspnea, cyanosis, Failure, the patient will soon die due to paralysis of the respiratory center, often only a few minutes to an hour, which is called “lightning death”. Compared with severe poisoning, patients first show obvious symptoms of upper respiratory tract mucosal infection: severe cough, spitting, sore throat, shortness of breath, blue complexion, and wheezing. When bronchopneumonia occurs, dry and wet rales can be heard on lung auscultation. The poisoning continues to increase, leading to alveolar edema, acute pulmonary edema, and systemic failure.
(3) First aid
Quickly remove the wounded from the scene and move them to a well-ventilated place. Let it rest quietly.
In order to relieve the patient’s dyspnea, inhale 2% to 3% warm and moist baking soda solution or 1% sodium chlorate solution, which can reduce the effect of chlorine gas on the upper respiratory tract mucosa.
It should be noted that during the rescue process, when a chlorine poisoning patient has difficulty breathing, artificial respiration methods such as chest compressions with bare hands should not be used. This is because chlorine has a strong detoxifying effect on the mucous membrane of the upper respiratory tract, causing bronchial pneumonia and even pulmonary edema. This pressure-style artificial respiration will aggravate inflammation and pulmonary edema, which is more harmful than beneficial.
Use cedilan and other cardiotonic agents as appropriate.
1% ~ 2% ephedrine or 2% ~ 3% procaine plus 0.1% epinephrine solution can be used as nasal drops.
