Foreword
Article 6.1 of this standard is recommended and the remainder is mandatory.
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 7796-1987 inconsistent with this standard, the standard shall prevail.
In the exposure to methyl bromide in the professional activities, can cause acute methyl bromide poisoning. To protect the health of the contact person, effectively
Prevention and control of methyl bromide poisoning, in 1987 the country promulgated GB 7796-1987.
Combined with recent research progress, the contents of the contents of the modified and added. And according to the specification requirements for the text and structure
The change. In the diagnostic system with the "occupational acute chemical poisoning diagnostic standards" series of standards.
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 Xi'an Central Hospital, China Center for Disease Control and Occupational Health and poisoning control is responsible for drafting. mountain
East Weifang City People's Hospital and Xi'an Municipal Health Bureau 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 methyl bromide poisoning
Occupational acute methyl bromide poisoning refers to the occupational activity in the short term exposure to a greater amount of methyl bromide caused by nerve
System, respiratory system damage as the main manifestation of systemic disease.
1 Scope
This standard specifies the diagnostic criteria and principles of occupational acute methyl bromide poisoning.
This standard applies to the diagnosis and treatment of occupational acute methyl bromide poisoning. Non-occupational acute methyl bromide poisoning can also be referred to
carried out.

3 diagnostic principles
According to the short-term exposure to a large number of methyl bromide occupational history, acute central nervous system, respiratory system-based clinical
Performance and other necessary clinical examination results, refer to on-site labor hygiene survey, comprehensive analysis, excluding other causes
Similar to the disease, can be diagnosed.
4 contact reaction
Eye and upper respiratory tract irritation symptoms, or headache, dizziness, fatigue and other neurological symptoms, from the contact after more
Disappeared within 24 hours.
5 Diagnostic and grading standards
5.1 mild poisoning
After a few hours to several days latency appears more obvious dizziness, headache, fatigue, gait stumble and loss of appetite, evil
Heart, vomiting, cough, chest tightness and other symptoms, and one of the following circumstances.
a) mild disturbance of consciousness;
b) mild dyspnea, lungs hear a small amount of dry, wet rales.
5.2 severe poisoning
The above situation has increased significantly and has one of the following conditions.
a) severe disturbance of consciousness;
b) Pulmonary edema.
6 Principles of handling
6.1 Principles of treatment
6.1.1 immediately from the scene, the replacement of contaminated clothing, skin contamination can be water, 2% sodium bicarbonate solution or soapy water.
6.1.2 Respondents should be observed for at least 48 hours, depending on the circumstances. Poisoning patients should stay in bed, keep quiet,
Close observation of changes in condition.
6.1.3 treatment to symptomatic treatment and support the treatment of the main. Early to actively deal with brain edema, pulmonary edema and so on.
6.2 Other treatments
Acute mild methyl bromide poisoning patients can be restored after the original work; severe poisoning patients should be transferred from the original job.
For identification of labor capacity, according to GB/T 16180 treatment.

Appendix A
(Informative)
Correctly use the instructions in this standard
A.1 acute methyl bromide poisoning to the nervous system, respiratory system, the two main target organ of the most prominent clinical manifestations,
This is the main basis for grading. In addition to the nerve, the respiratory system of clinical manifestations, the kidney damage is more common, light urine can be seen
There are protein, tube and red, white blood cells, severe cases can occur renal failure, can also die of uremia (see GBZ 79); liver
Dirty lesions are also more common (see GBZ 59); individual cases of myocardial damage, severe cases can also occur around the circulatory failure
See GBZ 74), in the diagnosis and treatment are noted.
A.2 The incubation period of this disease 2 minutes to 48 hours, mostly 4-6 hours, individual up to 5 days. Thus, the contact responder is at least viewed
Check for 48 hours.
A.3 blood bromine, urinary bromine and the field of air methyl bromide concentrations are contact indicators. Such as contact history is not clear, differential diagnosis difficult,
Determination of the above indicators have reference value.
Normal blood bromine below 25 μmol/L. General blood bromine > 62.5 μmol/L (50 mg/L) is a dangerous level to reach
187.5 μmol/L when the symptoms of poisoning. Urine bromine normal reference value of 12.5 μmol/L (10 mg/L).
A.4 acute methyl bromide poisoning should be associated with acute carbon monoxide poisoning, acute hydrogen sulfide poisoning, acute phosphine poisoning and acute
The nervous system of infectious diseases such as phase identification.
A.5 the disease without special antidote to support and symptomatic treatment based. In view of the mechanism of methyl bromide poisoning may contain mercapto groups with the body
Of the enzyme is inhibited, can try the mercapto-containing drugs such as cysteine and glutathione. Early application of glucocorticoid in the prevention and treatment
Lung, brain, kidney damage has an important role.
A.6 liquid or high concentration of methyl bromide can cause skin burns, the diagnosis and treatment can refer to GBZ 51.
