Eat popcorn popcorn Be careful of blood lead doctors: pre-pregnancy one month recommendation check
Doctors advise: Lead has an effect on sperm and eggs. One month before pregnancy, the husband and wife are best to check blood lead.
The last week of April is the Publicity Week of the Occupational Disease Prevention Act. This year is April 25-May 1. At present, China's occupational disease is still dominated by pneumoconiosis, accounting for 90% of outpatient clinics, followed by lead, mercury and other heavy metal poisoning. Heavy metal poisoning not only occurs in related professionals, but also in our daily lives, especially lead poisoning. Li Guohui, director of occupational disease and poisoning medical department of Hangzhou Red Cross Hospital, reminds: Before pregnancy, it is necessary for both husband and wife to check blood lead status.
Ninety percent of the lead absorbed by pregnant women is transmitted to the fetus through the placenta, leading to fetal congenital lead poisoning. After the fetus born with congenital lead poisoning, height, weight, and intellectual development will be affected. â€
Case number one
Using tin pots to add wine to detect blood lead exceeding 3 times in July
In more than two months, the baby was born. Ms. Chen, who was the mother of the mother, was very happy. She had packed her bag of delivery as early as a month ago. However, the result of an inspection more than a week ago shocked the couple. shocked. Ms. Chen’s blood lead levels were as high as more than 600, more than three times the normal range, which means she was lead poisoned. For ordinary people, as long as the treatment of lead is promptly treated, the problem is not great. She can put it on her. It is not as simple as she has a seven-month-old baby in her abdomen.
Director Li Guohui said: “Treatment of lead treatment during pregnancy is a very tricky thing. On the one hand, the treatment of lead treatment requires the use of drugs, and these drugs are not recommended for pregnant women. On the other hand, if premature treatment is not carried out, the mother and child The health of both parties will be affected, pregnant women may suffer from insomnia, early waking, abdominal cramps, toxic encephalopathy, etc. Ninety percent of the lead absorbed by pregnant women will be transmitted to the fetus through the placenta, leading to fetal congenital lead poisoning. After the fetus of lead poisoning is born, height, weight, and intellectual development will be affected."
Why Ms. Chen is lead poisoning? Director Li asked about the medical history and thought it might be related to her home tin pot. I suggest that her husband should also look for blood lead. The result confirmed Director Li’s guess that the blood lead level of Ms. Chen’s husband is also Up to 600 more. “Clinical findings found that some tin pots commonly used by ordinary people in the area are called 'pots of tin' as 'pots of lead', and 2/3 of the components are lead, because lead is plastic and the price is cheap. Under the effect of alcohol, lead will It is slowly being precipitated and then enters the body with cooking wine.â€
It is understood that Ms. Chen has been using this tin pot for some years. The frequency of using cooking wine in cooking at home is very high. Not only will it be used when burning fish, even fried vegetables will fall.
Case 2
Love to eat preserved eggs, popcorn mothers want to have a second child blood lead exceeded
Seeing on the laboratory test sheet, blood lead exceeded the normal range by more than two times. Ms. Fang, 33, was quite sceptical. She said that after the Spring Festival this year, she and her husband plan to regenerate a baby. He would have wanted to be a routine pre-pregnancy check, because both husband and wife usually have good health and good living habits. An occasional opportunity, she saw in the "mother group", many people recommend blood lead before pregnancy, she went to check. After receiving the test results, Ms. Fang received lead treatment.
Director Li Guohui said: “Lead is a metal that is naturally found in the earth's crust. It is ubiquitous in the natural environment and can be inhaled, eaten, and eaten into the body. Lead has a cumulative process in the body, so early lead Poisoning, the body can be asymptomatic, wait until the symptoms, and often have been poisoned deeper.If women in the case of lead poisoning, early pregnancy may lead to miscarriage, premature birth, premature rupture of membranes, stillbirth, etc., can lead to infant deformity."
Since it is lead poisoning, there must be a source. In the course of inquiring Ms. Fang’s medical history, Director Li discovered that she did not engage in lead-related occupations, nor did she have lead-containing utensils in her house. She then asked the details of life and diet to discover that she was very Love to eat preserved eggs, puffed food. "We think there is a certain relationship with her regular eating of these foods," said Li.
â– doctor's advice
Blood lead determination before pregnancy
Nanjing University Maternal and Child Health Hospital Affiliated to Nanjing Medical University, Dai Yongmei and Zhang Yue published an article entitled "Analysis of blood lead levels in 307 pre-pregnancy women and their related factors and the effects of compound nutrition interventions on lead excretion in Nanjing". Lead poisoning occurred in women before pregnancy. The rate was 18.9%. Regular consumption of preserved eggs and puffed foods were risk factors for women's lead poisoning (the paper was published in "China Maternal and Child Health Care" in 2010).
The analysis shows that in general, the higher the level of education, the less opportunity for occupational exposure to lead (such as mental workers and managers); the higher the level of education, the more knowledge of lead toxicity, family and personal hygiene habits The better, these can increase the resilience to lead pollution.
Studies have found that lead has teratogenic effects on sperm and eggs. Director Li Guohui suggested that couples planning to have children should go to the hospital to do blood lead tests before pregnancy, especially those engaged in the oil industry, metallurgical industry, battery industry, decoration industry, and auto sales personnel who are at high risk of lead poisoning. Pay attention. If blood lead exceeds the standard, it is recommended that you become pregnant after treatment. Since everyone's sensitivity to lead-removing drugs is different, sensitive people may complete one course of treatment (three or four days). Slower people may need four or five courses of treatment. Therefore, check one month in advance for insurance.
â– Small knowledge
These foods can be "leaded out"
Doctors also suggest that in daily life, you may properly eat “lead-expensing†foods such as dairy products. Dairy products are rich in calcium, which can competitively inhibit the absorption of lead and promote the metabolism of lead, thereby lowering blood lead levels.
In addition, the proper consumption of mung beans, garlic, kelp, carrots, green tea, kiwi and other foods, but also help accelerate the discharge of toxic substances in the body. (City Express)
