Benzene poisoning causes aplastic anemia to become an occupational disease killer

1n recent years, aplastic anemia caused by benzene poisoning continues to occur, and seriously threatens the lives of many workers. Experts said that in order to effectively protect the health rights and interests of workers, preventive health care measures must be taken to prevent benzene poisoning accidents

“although the state has issued repeated orders, the use of solvents, glues and coatings with high benzene content is still common in some factories. For example, the concentration of benzene in the working environment seriously exceeds the standard, and workers do not pay attention to protection. 1n the long-term working environment with high benzene content, the incidents of aplastic anemia caused by benzene poisoning continue to occur in recent years, 1n the past two years, our hospital has treated 30 to 40 such patients, mostly young workers. ” Guangzhou liuhuaqiao hospital biological treatment and Research Center Dr. Yang Demao told reporters that benzene toxicity aplastic anemia is still one of the high incidence of occupational diseases

complications caused by aplastic anemia

Xiaohu, 27 years old, works in a jewelry processing factory and is specially responsible for the bonding of jewelry. Therefore, he has “close contact” with glue containing benzene for a long time. Due to the lack of protective measures in the factory, Xiaohu works in this environment for a long time and unconsciously causes chronic benzene poisoning. Because of the frequent bleeding in his mouth and nose, he thought it was caused by fire and didn’t pay attention. One day when 1 was at work, 1 suddenly fainted and lost consciousness. 1 was sent to Guangdong occupational disease prevention and treatment hospital and was diagnosed with aplastic anemia. 1n order to treat tuberculosis, immunosuppressive therapy was initially used in the hospital, which seriously reduced the immune function of patients and led to secondary tuberculosis infection. At that time, the only hope was to carry out bone marrow transplantation, but the patient’s economy was not well-off, and there was no donor bone marrow with complete matching

“when he was transferred to the hospital, he was in a very critical condition. The young man in his 20s was extremely weak. The patient not only couldn’t walk, but also completely lost his ability to work. He had to rely on drugs and blood transfusion to maintain his life. 1n our hospital for nearly a year, the condition gradually improved, tuberculosis has also been cured Dr. Yang told reporters that not all patients are as lucky as Xiao Hu. Every year, a large number of patients still die of aplastic anemia because they can’t find matching bone marrow or can’t afford the high cost of surgery

according to Dr. Yang, the number of platelets, white blood cells and hemoglobin in the blood of patients with aplastic anemia is much lower than the normal level because of the hematopoietic dysfunction. 1t can’t supply normal physiological needs. Besides being extremely weak, the patient lacks platelets, which makes the patient’s mouth and nose often bleed. 1f he eats something harder, even the gastrointestinal tract will not stop bleeding. And the number of white blood cells is small, the patient’s resistance is very low, easy to be infected with complications such as tuberculosis< Biological therapy is superior to bone marrow transplantation Dr. Yang pointed out that bone marrow transplantation is the first choice for the treatment of aplastic anemia, but as far as China's current situation is concerned, the success rate of bone marrow matching is less than one third, and many patients can only rely on blood transfusion for survival, resulting in a serious decline in their quality of life. This is because, on the one hand, the stock of bone marrow is insufficient; On the other hand, the cost of bone marrow transplantation is also quite high, the average cost of each patient is more than several hundred thousand yuan, not including blood transfusion and other costs, which is difficult for ordinary people to bear. At the same time, bone marrow transplantation, like other organ transplantation, may have rejection phenomenon. 1n order to reduce rejection, patients need to use immunosuppressive drugs, which is also prone to other problems. Therefore, in recent years, many hospitals adopt new biological therapy, which has no bone marrow matching problem and low cost, and is suitable for all patients of the same kind. 1t has become a new hot spot in the research of blood disease treatment at home and abroad< According to the statistical data, the cure rate of biological therapy for aplastic anemia caused by benzene poisoning is as high as 100%, and the improvement of primary aplastic anemia is also very obvious< According to Dr. Yang Demao, benzene and other compounds enter the human body in the form of vapor in the production environment. When a large amount of high concentration of benzene is inhaled, it can produce acute benzene poisoning, mainly due to the anesthetic effect of the central nervous system. Mild cases may have excitement, euphoria, gait instability, headache, dizziness, dizziness, dizziness, dizziness Nausea, vomiting and mild unconsciousness. 1n severe cases, the consciousness became more blurred, coma or convulsion. 1n severe cases, the breathing stopped and the patient died at present, the common characteristics of benzene poisoning among workers engaged in painting, manufacturing, leather, packing and other operations are: most of the production enterprises are family workshops or small-scale processing enterprises, with low technical level, backward technology, poor working environment, lack of occupational protection facilities and personal hygiene protection articles, involving more personnel and serious consequences. 1n order to protect the health rights and interests of workers, preventive measures must be taken to prevent benzene poisoning accidents. The specific measures are: to replace benzene with low toxic or non-toxic substances; The production process and ventilation and detoxification should be reformed, such as the production process should be closed, automated and programmed, and the local ventilation and detoxification equipment with sufficient effect should be installed. Health care measures are: workers should wear gas masks or use masks, regular health examination this article is a reprint of 1nternet media, which only represents the author’s point of view and has nothing to do with this website. 1f the information column articles and comments violate your legal rights, please call to let us know and we will deal with them in time
