Diagnostic Criteria of Occupational Chemical Eye Burns ICS 13.100 C60 GBZ People's Republic of China National Occupational Health Standards Diagnostic criteria for occupational chemical eye burns Released in.2002-04-08 2002-06-01 Implementation Issued by the Ministry of Health of the People's Republic of China

Foreword

Article 4.1 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 16374-1996 inconsistent with this standard, the standard shall prevail. In professional activities, such as improper protection, eye contact with alkaline, acidic or other chemicals, gas or liquid The body can cause damage to the ocular tissue. To protect the health of the operator, to prevent the chemical burns, timely and positive Do this, develop this standard. Appendix A to this standard is an informative appendix and Appendix B is a normative appendix. This standard is proposed and centralized by the Ministry of Health of the People's Republic of China. This standard by the Peking University Third Hospital is responsible for drafting, the Chinese Center for Disease Control and Prevention Occupational Health and Poison Control, Ministry of Industry and Industry Health Department 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 chemical eye burns Occupational chemical eye burns are mainly due to the work of the eye directly contact with alkaline, acidic or other chemical gases, Liquid or solid damage caused by corrosive damage to the ocular tissue.

1 Scope

This standard specifies the diagnostic criteria and principles of occupational chemical eye burns. This standard applies to the diagnosis and treatment of occupational chemical eye burns.

2 diagnostic principles

According to a clear eye contact with chemicals or in a short period of time by high concentrations of chemical stimulation of occupational history, and to eyelids, Conjunctiva, cornea and sclera and other corrosive lesions of the clinical manifestations, refer to the operating environment survey, comprehensive analysis, excluding other Similar to the performance of the disease, can be diagnosed.

3 Diagnostic and grading standards

3.1 chemical conjunctival keratitis Obvious eye irritation symptoms. eye pain, burning sensation or foreign body sensation, tears, blepharospasm, conjunctival hyperemia, cornea Skin off and so on. Fluorescent staining has scattered dotted color. Slit lamp observation to the palpebral fissure site is most obvious. 3.2 mild chemical eye burns Those who have any of the following, can be diagnosed with mild chemical eye burns. a) eyelid skin or eyelid congestion, edema and blisters, no sequelae; b) conjunctival hyperemia, bleeding, edema; c) fluorescein staining slit lamp observed under the corneal epithelium can be seen diffuse punctate or flaky, corneal solid shallow water Swollen, limbal without ischemia or ischemia \u003cl／4。 3.3 Moderate chemical eye burns In addition to the above b, C two, and have any of the following, can be diagnosed as moderate chemical eye burns. a) the occurrence of conjunctival necrosis, repair period appears symblepharon; b) corneal parenchymal deep edema, limbal ischemia 1/4 to 1/2. 3.4 severe chemical eye burns Those who have any of the following, can be diagnosed with severe chemical eye burns. a) eyelid skin, muscle and/or tarsal ulcers, the emergence of scar edema ectropion, palpebral fissure incomplete; b) scleral necrosis, corneal opacity was porcelain white, and even perforation, limbal ischemia > l/2.

4 Principles of handling

4.1 Principles of treatment 4.1.1 chemical conjunctivitis and eyelid burns should be actively symptomatic treatment, if necessary, from the contact. 4.1.2 eye burns should be immediately washed near; carefully check the conjunctival fossa, remove the residual chemicals. 4.1.3 to prevent infection, accelerate wound healing, to prevent symblepharon and other complications. Severe eyelid deformity can be implemented Surgery 4.1.4 To prevent posterior iris adhesion, 1% atropine mydriasis can be used. 4.2 Other processing 4.2.1 chemical conjunctival keratitis, mild chemical eye burns in a few days to fully recover, vision is generally not affected, recovery The future can be restored to the original work. 4.2.2 moderate and severe chemical eye burns often produce serious complications or sequelae, visual function can be damaged to varying degrees. Monocular Burners should be disengaged from contact with chemicals, appropriate rest, according to the restoration of the arrangements for appropriate work; eyes burns, should be based on The residual vision at the end of the medical treatment, and decide whether or not to work or not.

5 Use the instructions of this standard correctly

See Appendix A (informative), Appendix B (normative).

Appendix A

(Informative) Correctly use the instructions in this standard A.1 This standard applies only to chemical damage caused by direct stimulation of the chemical, splashed into the eye or accident. Do not It is suitable for acute and chronic toxic ophthalmopathy caused by contact with chemicals outside the eye. A.2 Eye injuries caused by non-occupational exposure to chemicals may also be carried out with reference to this standard. A.3 Immediate treatment after eye burns is the key measure to determine the prognosis should be immediately, near the normal saline or clean Water thoroughly rinse the conjunctival sac, the amount of each eye at least 500 mL, rinse time is generally 5 ~ 10 min. A.4 The severity of the complications or sequelae of the burns after moderate and severe eye burns in the identification of labor capacity Visual impairment cases were different cases, comprehensive and specific analysis, discretionary treatment. A.5 Eye burns Chemicals are predominantly acid and alkali and are also found in other chemicals (see Table A.1).
