Diagnostic Criteria of Occupational Chronic n-Hexane Poisoning
Released in.2002-04-08

Issued by the Ministry of Health of the People's Republic of China
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.
N-Hexane is a commonly used organic solvent for industrial production. In contact with n-hexane professional activities, workers may be due to workplace
Poor ventilation or improper protection and chronic poisoning. For the effective prevention and treatment of chronic n-hexane poisoning, protection of workers health, system
Standard set.
The development of this standard is in line with both the occupational acute chemical poisoning of the general standard of convergence, but also highlight the chronic positive
Hexane poisoning characteristics, and strive to be suitable for practical application of the principle of summing up and analysis of domestic and foreign nearly 30 years of chronic n-hexane
Poisoning on the basis of clinical research progress.
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 Guangdong Provincial Occupational Disease Prevention and Control Hospital, Guangdong Province, Shenzhen City Health and Epidemic Prevention Station is responsible for drafting. Shenzhen Baoan, Guangdong Province
District Health and Epidemic Prevention Station and Guangdong Province, Longgang District, Shenzhen Health and Epidemic Prevention Station 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 chronic n - hexane poisoning
Occupational chronic n-hexane poisoning refers to the workers in the professional activities of long-term exposure to n-hexane caused by peripheral nerve damage
Harm the main disease.
1 Scope
This standard specifies the diagnostic criteria and principles of occupational chronic n-hexane poisoning.
This standard applies to the occupational activity due to long-term exposure to n-hexane caused by chronic poisoning diagnosis, non-occupational due
The diagnosis of chronic n-hexane poisoning can also refer to this standard.
2 normative reference documents
The 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.
Identification of Occupational Injury and Occupational Disease Disability in Staff and Workers GB/T 16180
GBZ 76 Occupational acute chemical poisoning Nervous system disease diagnostic criteria
3 diagnostic principles
According to the long-term exposure to n-hexane occupational history, the emergence of multiple peripheral nerve damage-based clinical manifestations, combined with the experiment
Room inspection and workplace hygiene investigation, comprehensive analysis, excluding other causes of similar diseases, can be diagnosed.
4 observation object
Long-term exposure to n-hexane without peripheral nerve damage signs, but with one of the following.
a) limb distal numbness, pain, lower limb heavy feeling, may be accompanied by cold hands and feet sweat, loss of appetite, weight loss,
Dizziness, headache and so on;
b) Neuro-electromyography shows suspicious neurogenic damage.
5 Diagnostic and grading standards
5.1 mild poisoning
The above symptoms are aggravated and have one of the following.
a) limb distal symmetry distribution of pain, tactile or tuning fork vibration disturbance, accompanied by Achilles tendon reflex;
b) Neuro-electromyography shows positive neurogenic damage.
5.2 moderate poisoning
On the basis of mild poisoning, with one of the following.
a) Achilles tendon reflex;
b) lower limb muscle strength 4 degrees;
c) Neuro-electromyography shows neurogenic damage and has more spontaneous denervation potential.
5.3 severe poisoning
On the basis of moderate poisoning, with one of the following.
a) lower limb muscle strength 3 degrees or less;
b) limb distal muscle atrophy, and affect the motor function.
6 Principles of handling
6.1 Principles of treatment
6.1.l out of contact;
6.1.2 Integrated Chinese and Western medicine therapy, supplemented by acupuncture, physical therapy and limb motor function exercise.
6.2 Other treatments
Mild poisoning can be re-returned to the original job, moderate and severe patients should not be engaged in contact with n-hexane
And other work that can cause peripheral nerve damage. For the identification of labor capacity, according to GB/T 16180 treatment.
7 Correctly use the instructions in this standard
See Appendix A (informative).
Appendix A
(Informative)
Correctly use the instructions in this standard
A.1 This standard applies to the diagnosis and treatment of chronic poisoning cases caused by long-term exposure to n-hexane in occupational activities. Non - professional
Chronic n-hexane poisoning can also be followed by reference.
A.2 multiple peripheral neuropathy is the clinical features of this disease and diagnostic starting point, the diagnosis of multiple peripheral neuropathy is based on
Limb distal to the side of the bilateral symmetry of sensory abnormalities or sensory disturbances, lower motor neuron dyskinesia and neural - EMG
Figure shows the performance of neurological damage changes. The diagnosis of the classification, according to the degree of peripheral nerve damage.
A.3 Diagnostic grading standards mentioned in the muscle strength test methods and classification principles according to GBZ 76 in Appendix C "muscle strength grading standards"
carried out.
A.4 Diagnostic grading standards mentioned in the EMG inspection methods and abnormal results to determine the basis of GBZ 76 in the appendix
B.1 and B.2.
A.5 observed subjects with early symptoms of peripheral nerve damage without clear signs, or neurological-electromyography only show suspicious gods
The source of damage, it is not classified as poisoning. But some of the observed object is actually latent in the chronic n-hexane poisoning patients, latent
Period of up to 3 months, so the observation object should be out of contact, and accept the observation of 3 months, observed during the attention may occur
Peripheral nerve damage, 3 months of observation without peripheral nerve damage evidence, can rule out chronic n-hexane poisoning.
A.6 Urine 2,5-hexanedione is only a recent indicator of n-hexane exposure and is not associated with the clinical manifestations of chronic n-hexane poisoning
Not included as a diagnostic indicator.
A.7 Treatment of chronic n-hexane poisoning should be done using a combination therapy, including disengagement, ensuring that the patient has adequate nutrition, given
B vitamins, energy mixture, blood circulation, Tongluo kidney Chinese medicine, and supplemented by acupuncture, physical therapy, and limb motor function
Exercise and so on.
