According to the "People's Republic of China Occupational Disease Prevention Law" to develop this standard. Since the implementation of the standard date, the original standard GB 11507-1989 inconsistent with this standard, the standard shall prevail. Dimethyl sulfate is a widely used in the chemical industry of methylated substances. In contact with dimethyl sulphate for professional activities , Can cause acute dimethyl sulfate poisoning. To protect the health of the contact person, the prevention and treatment of acute dimethyl sulfate poisoning, according to The latest progress in clinical research, GB 11507-1989 was revised. The revised standard is based on both "occupational acute chemicals toxic respiratory disease diagnosis" (GB 165852-6) phase convergence, but also highlight the characteristics of acute dimethyl sulfate poisoning itself, based on the original standard Plus the classification of laryngeal edema, blood gas analysis and chest X-ray characterization and so on, so that the diagnostic classification is more clear, Easy to apply. Appendix A to this standard is an informative appendix. This standard is proposed and centralized by the Ministry of Health of the People's Republic of China. This standard by the Liaoning Provincial Occupational Disease Prevention Hospital, Shanghai Yangpu District Central Hospital is responsible for drafting. Protection of chemical industry in Shanghai Hospital, Benxi City, Liaoning Province, occupational disease prevention and treatment hospital, Dandong City, occupational disease prevention and control hospital, Chaoyang City, occupational health and disease prevention and control Fushun aluminum plant to participate in the drafting. This standard is interpreted by the Ministry of Health of the People's Republic of China. Diagnostic criteria for occupational acute dimethyl sulphate poisoning Occupational acute dimethyl sulfate poisoning is caused by a large amount of dimethyl sulfate in the short period of time in the occupational activity Of the respiratory system as the main manifestation of systemic diseases. Often accompanied by chemical burns of eyes and skin.1 ScopeThis standard specifies the diagnostic criteria and principles of occupational acute sulfuric acid dimethyl alcohol poisoning. This standard applies to occupational poisoning caused by exposure to dimethyl sulfate in occupational activities. Non - professional activities Touch of dimethyl sulfate caused by the diagnosis of acute poisoning, can also refer to this standard.2 normative reference documentsThe terms of the following documents are hereby incorporated by reference into this standard. Any date that references the date of the document All subsequent amendments (excluding corrigenda) or revisions do not apply to this standard, however, The parties to the agreement are able to use the latest version of these documents. Those who do not mind the date of the reference file, its latest The version applies to this standard. GBZ 51 Occupational chemical skin burns diagnostic criteria GBZ 54 Occupational chemical eye burns diagnostic criteria GBZ 73 Occupational acute chemicals - Criteria for the diagnosis of toxic respiratory diseases Identification of Occupational Injury and Occupational Disease Disability in Staff and Workers GB/T 161803 diagnostic principlesAccording to the short-term exposure to a large number of dimethyl sulphate occupational history, the clinical manifestations of acute respiratory system damage, and chest X Ray performance, reference to blood gas analysis and on-site labor hygiene survey data, comprehensive analysis, and exclude other causes due to similar Disease, can be diagnosed.4 stimulus responseOnly a transient eye and upper respiratory tract irritation symptoms, no positive signs of the lungs, chest X-ray showed no abnormal performance.5 Diagnostic and grading standards5.1 mild poisoning One of the following. a) have obvious eye and upper respiratory tract mucosal irritation symptoms, such as eye pain, tears, sore throat, hoarse voice, cough, chest Boring, etc .; signs of conjunctival hyperemia edema, and even eyelid edema, uvula congestion congestion, the lungs are scattered in dry or (and) wet Sexual rales; chest X-ray performance for the increase in lung texture, thickening, blurred edges, some visible halo ring sign. The above performance is consistent Acute bronchitis or bronchial inflammation. b) upper respiratory tract irritation symptoms, there was once to twice the laryngeal edema; lung no abnormal signs; chest X Line check can also be no positive signs. 5.2 moderate poisoning One of the following. a) cough, expectoration, chest tightness, shortness of breath, often mild cyanosis; lungs can be heard and dry or wet rales; chest X Line performance for the two, the lower lung dot or small patchy shadow. The above performance in line with acute bronchial pneumonia; b) cough, expectoration, chest tightness, shortness of breath, two lungs breath sounds weakened. Chest X-ray showed increased lung texture; Hilar shadow increased, blurred, scattered in the small spine or mesh shadows, lung field through the degree of reduction, often visible bronchial halo ring sign, Interlobular fissure widened and discoid atelectasis. The above performance in line with acute interstitial pulmonary edema; c) three laryngeal edema. Blood gas analysis often mild to moderate hypoxemia. 5.3 severe poisoning One of the following. a) obvious difficulty breathing, cyanosis, slightly large amount of white or pink foam sputum; lung diffuse wet rales; chest X Ray performance of the lungs of varying sizes, the edge of the flaky flake or cloud-like shadow, and sometimes can be integrated into large shadow. the above Performance consistent with alveolar pulmonary edema. b) acute respiratory distress syndrome; c) four throat edema; d) bronchial mucosal necrosis leads to asphyxia; e) complicated by severe pneumothorax or mediastinal emphysema. Blood gas analysis often severe hypoxemia.6 Principles of handling6.1 Principles of treatment 6.1.1 quickly and safely off the scene, take off contaminated clothing, and immediately rinse the contaminated eye and skin with flowing water. For those who have symptoms of irritation, should be closely observed for 24 hours, observation period should avoid activities, bed rest, keep quiet. give Symptomatic treatment to control disease progression, prevention of laryngeal edema and pulmonary edema. 6.1.2 to maintain airway patency, can be given inhalation therapy, bronchial antispasmodic agents, to defoamers (such as dimethyl silicone oil), If necessary, tracheotomy. 6.1.3 Reasonable oxygen therapy. 6.1.4 early, adequate, short-range application of glucocorticoid. 6.1.5 to prevent infection, prevention and treatment of complications, maintaining water and electrolyte balance. 6.1.6 eye, skin burn treatment, with reference to GBZ 54 or GBZ 51 implementation. 6.2 Other treatments Mild, moderate poisoning patients can be restored after the original work; severe poisoning patients should be transferred from the original job; Dynamic ability identification, according to GB/T 16180 treatment.7 Correctly use the instructions in this standardSee Appendix A (informative).Appendix A(Informative) Correctly use the instructions in this standard A.1 The diagnostic grade of this standard is mainly based on the degree of damage to the respiratory system. Stimulation reactions are not classified as acute poisoning. Acute bronchitis or peri-pulmonary inflammation and once to twice the throat edema of the diagnosis of the starting point of the disease. A.2 laryngeal edema is one of the outstanding manifestations of acute dimethyl sulfate poisoning, its severity can directly reflect the severity of the disease. Dimethyl sulfate acute poisoning laryngeal edema caused by breathing dyspnea four degrees, once. quiet when no breathing difficulties, activities Show breathing difficulties; second. quiet also have mild "three pins", activities, increased, but does not affect sleep, also No irritability; three degrees. breathing difficulties are obvious, "three concave" significant, and there are irritability, not easy to sleep; four degrees. In addition to the performance of three times the difficulty of breathing, there are restless, cold sweats, pale or cyanosis, the last coma or even heartbeat stopped. A.3 Blood gas analysis PaO2 determination can objectively reflect the severity of hypoxia. It can be used as a reference index for diagnostic grading. low Oxygen is divided into three degrees. PaO2 ≤ 10.7kPa (80mmHg), moderate PaO2 ≤ 8 kPa (60mmHg), severe PaO2 ≤ 5.3 kPa (40 mmHg). To determine the degree of hypoxia should also be combined with clinical, dynamic observation, remove the technical error. A.4 diagnostic criteria for acute respiratory distress syndrome in this standard, refer to GBZ 72. A.5 light, medium and severe acute dimethyl sulfate poisoning can be associated with eye or skin chemical burns, the diagnosis of grading see GBZ 54 or GBZ 51. A.6 acute poisoning is often associated with ECG and liver, renal function of a transient change. Due to consider the secondary hypoxia caused by no specific Sex, it is not included in the diagnostic terms. Diagnosis can be based on specific circumstances, comprehensive comprehensive analysis. A.7 Inhalation is one of the effective ways to treat acute toxic respiratory diseases, depending on the condition of 3-5 times a day Sound inhalation. Such as hyperthyroidism severe edema, or laryngeal edema is more obvious, do ultrasonic inhalation will make ventilation more difficult, this Can be used to do artificial spray oral anesthesia, or ultrasonic atomizer connected to the use of oxygen bottles. A.8 poisoning, such as the emergence of three to four degrees of laryngeal edema, once the conservative treatment should be timely when the tracheal function should be carried out in order to avoid Serious consequences. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GBZ40-2024_English be delivered?Answer: Upon your order, we will start to translate GBZ40-2024_English as soon as possible, and keep you informed of the progress.
