Diagnostic criteria and principles of management of occupational acute hydrogen sulfide poisoningUDC 616-057 : 616

GB8789-88
Occupational acute hydrogen sulfide poisoning is a systemic disease mainly caused by damage to the central nervous system, conjunctiva and respiratory system caused by exposure to a large amount of hydrogen sulfide in a short period of time in the production environment.
TDiagnostic principles
Based on the occupational history of short-term exposure to hydrogen sulfide, the rapid appearance of clinical manifestations of varying degrees of damage to the central nervous system, respiratory system and conjunctiva, and reference to the on-site labor hygiene survey data, the diagnosis can be made only after excluding similar diseases caused by other causes. 2 Diagnosis and classification standards
2.1 Irritation reaction
After exposure to hydrogen sulfide, the patient has irritation symptoms such as tearing, eye stinging, runny nose, and burning sensation in the throat, and recovers in a short time. 2.2 Mild poisoning
There are symptoms such as eye swelling and pain, photophobia, dry throat, cough, mild headache, dizziness, fatigue, nausea, etc. Examination shows conjunctival congestion and signs such as rales in the lungs.
2.3 Moderate poisoning
The patient with one of the following clinical manifestations is diagnosed as moderate poisoning; and. There are obvious symptoms such as headache and dizziness, and mild consciousness disorder. b, there are obvious mucosal irritation symptoms, such as cough, chest tightness, blurred vision, conjunctival edema and corneal ulcer. There are audible or wet rales in the lungs, and the chest X-ray shows enhanced lung texture or flaky shadows. 2.4 Severe poisoning
Those with any of the following clinical manifestations shall be diagnosed as having died of leukemia: a. coma,
b. pulmonary edema; bzxz.net
respiratory circulatory failure;
lightning-type death.
3 Treatment principles
3.1 Leave the scene quickly and give oxygen immediately. If conditions permit, hyperbaric oxygen therapy can be used for moderate and severe poisoning to keep the airway open. Symptomatic treatment is taken for eye damage.
3.2 The principles of rescue treatment are the same as those of internal medicine. Symptomatic and supportive treatment such as heart, lung and brain resuscitation shall be immediately carried out for those with respiratory and cardiac arrest. Approved by the Ministry of Health of the People's Republic of China on February 22, 1988 and implemented on September 1, 1988
4 Work capacity assessment
Mild to moderate poisoning
Moderate poisoning
Resume the original work after recovery.
GB 8789—88
After recovery from treatment, the patient can be given rest according to the condition and can generally resume the original work. c. Severe poisoning
After treatment, the patient can be transferred from the harmful work according to the work needs. For patients whose nervous system damage has not fully recovered, rest and treatment should be arranged.
Requirements for health examination
Workers working with hydrogen sulfide should undergo regular health examinations before employment and every 1 to 2 years. 5.1
5.2 The physical examination should include internal medicine, ENT, neurology and chest X-ray examinations. 6 General occupational prohibition certificate
Obvious respiratory diseases;
Organic diseases of the nervous system and mental disorders; obvious organic heart, liver and kidney diseases. GB8789-88
Appendix A
Instructions for the correct use of the standard
(reference)
A.1 This standard applies to occupational acute hydrogen sulfide poisoning. The diagnosis and treatment of non-occupational acute hydrogen sulfide poisoning can also refer to this standard.
A.2 For some moderate and severe cases, the conjunctival and respiratory system damage may not be prominent, and the diagnosis is mainly based on the clinical manifestations of the central nervous system.
.3 Mild consciousness disorder includes confusion and trance, which generally does not last for half an hour (see Appendix A of GB 8781-8 Diagnosis Criteria and Treatment Principles for Occupational Acute Carbon Dioxide Poisoning). A.4 When severe hydrogen sulfide poisoning does not leave behind neurasthenia, mental disorders, and idiopathic peripheral neuropathy, it should be differentially diagnosed from related diseases in internal medicine and neuropsychiatry. A5 Poisoned patients must be removed from the scene quickly. Patients with respiratory arrest should be given artificial respiration and cardiopulmonary and cerebral resuscitation treatment immediately. Additional notes:
