Talking about “lead” is the state of almost all mothers and fathers. The lead in life is almost impossible to prevent: the haze time and again, the car exhaust that cannot be avoided, even the glass and wallpaper at home, the cosmetics carefully selected by mothers, all may contain a small amount of metallic lead, which sneaks into the baby’s body and accumulates, causing great harm. Many mothers have a lot of questions: Is the blood test for lead in the veins or in the fingertips? My baby is one week old, and the other day I checked the blood lead indicator of 65, is it too high? My neighbor has a child with high blood lead level, should my baby have a blood lead test? 1.How to test whether lead is over the limit? At present, there are mainly two ways of blood lead testing: ① venous blood testing (“blood sampling”); ② peripheral blood testing (“finger tapping”). Among them, the results obtained from venous blood collection are more accurate. Although the hair test does not require blood collection, there are more factors affecting the results and the results are not accurate. Some moms want to ask, what is the normal value of blood lead? Lead, as a heavy metal, should not exist in human body. The higher the blood lead level is, the more harmful it is. ① Over 100ug/L, it is called hyperleademia; ② Over 200ug/L, it is called lead poisoning; ③ Over 450ug/L, it is called severe lead poisoning. 2.The danger of lead! Babies are more prone to lead poisoning than adults because they prefer to use their mouths to lick and bite contaminated objects and toys, as well as not paying attention to hand washing. In addition, the gastrointestinal tract of babies is also more likely to absorb lead. Almost all organs of the body can be damaged by lead. Babies with vigorous growth and development are more obviously affected. The danger of lead is insidious, and by the time the symptoms of lead poisoning appear, the blood lead level is often already very high. In particular, the symptoms of lead poisoning in babies are very atypical and need to be clarified by blood lead testing. However, there are some symptoms that should be alerted. ①Acute and subacute lead poisoning If a baby is exposed to a large amount of lead in a short period of time, it will trigger acute and subacute poisoning. The baby may say that there is a metallic taste in his mouth, and he may show signs such as drooling, vomiting, severe stomach pain, and even loss of sensation at the ends of his hands and feet. ② Chronic lead poisoning If the exposure is long time and low dose, and the lead accumulated in the body reaches the poisonous dose, there will be chronic poisoning manifestation. ① Blood lead <100ug/L, but the level is high: damage the baby's intelligence and hearing; ② Blood lead >100ug/L, affect the growth and development, leading to the child’s growth and development backward; ③ Blood lead >200ug/L, may cause anemia, nerve damage, etc.; ④ Blood lead >800ug/L, may lead to brain damage, nephrotoxicity; ⑤ Blood lead >1250ug/L, the baby may occur acute Brain damage and even death. 3.Where is the lead hidden in life? Since the consequences of lead poisoning are so serious, mothers and fathers must want to keep their babies away from dangerous objects. The inks, brushes, colored playdough, brightly colored toys and fancy tableware that babies often play with may all contain lead. All kinds of snacks and canned food containing artificial coloring contain lead, in addition, the lead content in car exhaust, industrial waste gas and polluted air is high. 4.When is it recommended to test blood lead? Regular blood lead testing is recommended for high-risk groups: ① Children under 6 years old who live near high-risk areas (smelters, battery factories and other factories with lead operations) should consider regular screening for lead poisoning; ② Children who have frequent contact with people who are engaged in lead operations (construction and decoration, stained glass, industrial paint, ceramic glaze and other industries) should pay attention to monitoring blood lead; ③ Siblings or small friends around them with lead exceeds the standard, which should also be alerted; ④ Exposure to peeling paint environment or recent renovation at home is also a risk factor. Other cases can be considered for blood lead testing: children with poor hygiene behavior (frequent contact with dust, love to bite unclean things, do not like to wash hands, etc.), symptoms of lead overdose (mentioned above), or parents are particularly worried (making judgments based on daily life), these cases can also be considered for blood lead checking, because lead is very harmful and lacks specific early manifestations. 5.Prevention and treatment of lead poisoning! Prevention is the key to lead poisoning! Emphasis on prevention! Emphasis on prevention! Say the important thing three times! (1) Develop good hygiene habits and behavioral habits to reduce lead exposure and intake. ①Educate children to develop the habit of washing hands regularly, especially before meals; ②Cut nails regularly, nail crevices are very easy to hide lead dust; ③Children’s toys should be washed frequently, and use clean rags to scrub the dust that children can reach; ④Don’t stay and play near lead working factories, and janitors engaged in lead work must remember to change clothes and take a shower before work; ⑤Clean homes with coal burning should open windows more often for ventilation, and avoid passive smoking (6) children’s tableware, toys, etc., avoid the use of colorful and shoddy products; (7) avoid giving children food with high lead content such as leather eggs, popcorn baked in old popcorn machines; (8) do not use tap water that has been left in the pipes for a long time for children to drink or brew milk. (2) Good eating habits and nutritional status can reduce the absorption of lead. When the child has poor nutrition or lack of calcium, iron, zinc and other elements, it will increase the absorption of lead. Therefore, make your child develop good eating habits: ① Eat meals regularly, with a variety of foods to ensure comprehensive and balanced nutrition; ② Eat more calcium-containing foods, such as milk and soybean products; ③ Eat more meat, animal liver, eggs, etc., which are rich in iron and zinc; ④ Eat more vegetables and fruits rich in vitamin C. (3) For moderate and more serious lead poisoning, seek medical attention and carry out lead expulsion treatment under the guidance of doctors.
