In a variety of professional activities, may be in a short period of time exposure to some high concentrations and high toxicity of chemicals and then acute poison. These chemicals can be known varieties, and some have been poisoned after a fashion is unknown its exact pathogenic varieties; some Species caused by poisoning in the "list of occupational diseases" in the famous, and some are not yet included; some have independent diagnostic criteria, and some It has not yet developed a separate diagnostic criteria. But all of the acute poisoning diseases have a common incidence of the law, it is necessary Develop rules that should be observed when diagnosing acute poisoning. The rules stipulated in this standard refer to the diagnosis of occupational acute chemical poisoning, which are used to ensure occupational The unity of the diagnostic system of acute chemical poisoning, whether known or concealed by the cause, and whether it is caused by poisoning Which target organ damage, can be in accordance with the provisions of this standard rules for diagnosis. In the diagnosis of occupational acute chemical poisoning under the general heading, including the following 10 parts. Part 1. Diagnostic criteria for occupational acute chemical poisoning (general); Part 2. Occupational acute occult chemical poisoning diagnostic rules; Part 3. Occupational acute chemical toxicity - Multiple diagnostic criteria for multiple organ dysfunction syndrome; Part 4. Diagnostic criteria for occupational acute exogenous death; Part 5. Occupational acute chemical toxicity - Criteria for the diagnosis of neurological diseases; Part 6 Occupational acute chemicals - Criteria for the diagnosis of toxic respiratory diseases; Part 7. Diagnostic criteria for occupational acute toxic liver disease; Part 8. Diagnostic criteria for occupational acute toxic nephropathy; Part 9 Occupational Acute Chemicals - Toxic Cardiac Disease Diagnostic Criteria; Part 10 Occupational Acute Chemicals Toxicity Diagnostic criteria for blood system diseases; Appendix A to this standard is an informative appendix.

4 clinical type and diagnostic grade

Occupational Acute Chemicals Toxicity The common clinical types of blood system diseases are as follows. 4.1 toxic hemolytic anemia 4.1.1 mild. poisoning after fatigue, chills, fever, low back pain, burnout, headache, nausea, vomiting, abdominal pain. skin Sclera yellow dye, anemia appearance; blood test red blood cells and hemoglobin reduction, reticulocyte increase, Herne body Urine; urinary occult blood positive, protein positive, red, white blood cells and tube, blood urea nitrogen base This is normal. 4.1.2 severe. rapid onset, sudden chills, fever, delirium, convulsions, coma, cyanosis, scleral deep yellow dye, oliguria Or no anuria, severe anemia; red blood cells and hemoglobin decreased significantly, reticulocytes increased significantly, Herne body mass out Now, the urine was deep sauce, urine strong positive blood, blood urea nitrogen increased sharply, showing acute renal failure performance. 4.2 toxic hyperchromatic hemoglobinemia (MHb) 4.2.1 mild. general MHb concentration of 10% or more, lips around the cyanosis, can be asymptomatic. 4.2.2 moderate. MHb concentration of 40% to 60%, in addition to significant cyanosis, the emergence of hypoxia symptoms, such as headache, dizziness, Fatigue, weakness, body aches, difficulty breathing, tachycardia, unresponsive, lethargy and so on. 4.2.3 severe. MHb concentration of 60% or more, the above symptoms were significantly increased, the face was cyanotic, urine was grape or Dark brown, can occur in acute circulatory failure, coma, death. 4.3 toxic hematopoietic hemoglobinemia 4.3.1 mainly for hypoxia, may have cyanosis, headache, etc., some patients may coexist methemoglobin, hemolytic performance. 4.3.2 blood sulfide hemoglobin accounted for 2% of total hemoglobin, or even more than 10%. 4.4 toxic acute aplastic anemia 4.4.1 acute onset, was anemia, bleeding tendency, infection fever. 4.4.2 peripheral blood. red blood cells and hemoglobin decreased rapidly, the extreme reduction of white blood cells (neutrophils absolute < 0.5 × 109/L), platelet was significantly reduced (< 20 × 109/L), reticulocyte < l%, absolute value < l5 × 109/L. 4.4.3 bone marrow. nuclear cell proliferation is low, granulocyte, red and megakaryocyte cells were significantly reduced, the relative increase in the proportion of lymphocytes, Plasma cells, reticular cells, tissue basophils are easy to see. Bone marrow biopsy hematopoietic tissue reduction, mostly replaced by adipose tissue. 4.5 toxic myeloid deficiency 4.5.1 acute onset, sudden chills, fever, sweating, headache, body and joint pain, followed by angina associated with submandibular, Cervical lymph nodes, a few days after necrotic ulcers, common in the tonsils, soft palate, lips, tongue, skin, nasal cavity, rectum, Anus and vagina, etc., and secondary sepsis. 4.5.2 peripheral blood. white blood cell count is extremely reduced, neutrophils can only account for 1% to 2%, red blood cells and platelets The number of basic normal. 4.5.3 bone marrow. bone marrow in the sub-leaf nucleus, rod-shaped nucleus, young and middle and young cells often absent, only a small amount of the original grain and early Granulocytes, but the proportion of plasma cells, lymphocytes and mononuclear cells increased, red and megakaryocyte lines were normal. 4.6 toxic vasculopathy purpura 4.6.1 skin bleeding, more common in the limbs, buttocks showed edema of the petechiaceae into a piece or into a bubble; also have blood in the stool, abdominal pain and Joint pain and so on. 4.6.2 platelet count, bleeding or clotting time is normal, capillary brittleness positive. 4.7 Toxic thrombocytopenia 4.7.1 bleeding to limbs skin and nose, gums, tongue, oral mucosa is more common, rare hemoptysis, hematemesis, hematuria, black manure And fundus and intracranial hemorrhage. 4.7.2 Platelet count reduction (< 50X109/L =. 4.7.3 bone marrow. megakaryocyte reduction, erythroid and granulosa cells roughly normal, may have nuclear left shift phenomenon. 4.7.4 bleeding time can be extended, blood clotting bad, abnormal prothrombin time, blood clotting time can be normal. 4.7.5 immune mechanism caused by thrombocytopenia, can detect platelet membrane-related antibodies. 4.8 toxic platelet dysfunction 4.8.1 symptoms of varying severity, more common nose bleeding, bleeding gums, severe cases can also have subcutaneous hematoma, hematuria, black manure and so on. 4.8.2 platelet count and out, clotting time is normal, platelet adhesion and platelet aggregation function decreased, platelet Ⅲ Lack or release disorder. 4.9 toxic thrombinogen synthesis disorder 4.9.1 visible epistaxis, gingival bleeding, skin petechia or ecchymosis, excessive menstrual flow and hematuria, black manure, hemoptysis and intracranial Bleeding and so on. 4.9.2 prothrombin time (PT) prolonged, white clay partial thromboplastin time (KPTT) prolonged, clotting time (CT) And calcium recovery time. 4.10 Toxicity disseminated intravascular coagulation 4.10.1 seen in a variety of severe chemical poisoning poisoning. 4.10.2 Multiple bleeding tendency. 4.10.3 multiple microvascular thrombosis, the corresponding parts of the symptoms and signs of embolism. 4.10.4 is not easy to use the original disease explained microcirculation failure and shock. 4.10.5 laboratory tests. platelet showed a sustained reduction in dynamic; plasma fibrinogen content of less than 1.5 g/L or carried out (PDP) greater than 20 mg/L; PT and KPTT prolonged; 3 P test positive or plasma fibrinogen degradation products (FDP) greater than 20 mg / Long and so on.

5 Principles of handling

5.1 Principles of treatment 5.1.1 out of contact, eliminate pollution, quiet rest. If the indications can be applied special effects detoxification drugs. 5.1.2 toxic hemolytic anemia to take alkaline urine, as soon as possible the use of high-dose glucocorticoid control hemolysis, protection of kidney function Can, severe use of blood purification therapy. 5.1.3 toxic hypergammic hemoglobinemia treatment can be used in the United States and blue and vitamin C and correct hypoxia and other symptomatic, support Treatment. US blue dosage of 1mg/kg, slow intravenous injection, suffering from 6-phosphate dehydrogenase deficiency should not be applied to avoid hair Health hemolytic reaction. 5.1.4 treatment of toxic thiogulinemia, mainly for symptomatic treatment, the use of US blue and vitamin C is invalid. 5.1.5 toxic acute aplastic anemia. blood transfusion, androgen and glucocorticoid application, control of infection, etc. Type can choose to try anti-lymphoid (thymus) cell globulin, cyclosporin A or allogeneic bone marrow transplantation. 5.1.6 toxic granulocyte deficiency can be used granulocyte colony stimulating factor (GCSF). 5.1.7 toxic vasculopathy, toxic thrombocytopenia, toxic platelet dysfunction, toxic prothrombin Synthetic disorders and toxic disseminated intravascular coagulation and other coagulation disorders, according to the principle of medical treatment. 5.2 Other processing Toxic hemolytic anemia and toxic methemoglobinemia were cured, the mild were removed from the original species of visual disease Situation and labor conditions, etc., medium and severe should be transferred from the original type of work. Hemolytic anemia according to the presence or absence of kidney damage And the degree of arrangement of light work or rest. Toxic hematopoietic hemoglobinemia, toxic myeloid deficiency, toxic acute aplastic anemia and toxic Vascular purpura, toxic thrombocytopenia, toxic platelet dysfunction, toxic thrombinogen synthesis disorder and Toxic disseminated intravascular coagulation and other coagulation disorders of the patient cured after the removal of the original species, rest or arrange light work.
