What should I do if my baby has a red butt?

Question 1: My baby has red buttocks, and the diaper is changed frequently, and the buttocks are washed after each change. I still have allergies after applying Andy Bell Lithospermum Ointment frequently, what should I do? Dr. Luo Zhen answered: The baby has diaper dermatitis, which is mainly caused by irritation after the feces is decomposed by bacteria. The most important thing is to take good care of it, change diapers in time, and wash the buttocks and perineum with warm water every time you change diapers. After washing, wipe dry and blow with a hair dryer to keep it dry. You can use Lithospermum ointment for a slightly red butt. Now it seems to be leaking, which may lead to secondary bacterial infection. It is recommended to apply Baiduobang ointment and zinc oxide ointment three or four times a day in a ratio of 1:1. The most important thing is to keep it clean, hygienic and dry, otherwise it is easy to relapse. Question 2: I accidentally broke the thermometer today. Only part of the mercury was found, and part of it was missing. I have a baby at home, will it affect the baby? Dr. Cui Lixia answered: If it is on the ground, you can mop the floor a few times with a mop, then throw away the mop and open the window for ventilation. A thermometer contains very little mercury, so it\’s not a big problem. Generally, mercury poisoning will cause nausea, vomiting, etc. in the early stage. In the long term, it may cause hair loss, slow development, etc. Question 3: The baby is one and a half years old and has vomited three times since yesterday. The baby is in good spirits but vomits whatever he eats. What should I do? Dr. He Jiexin answered: It is considered to be caused by gastrointestinal discomfort. If the vomiting is still severe, it is best to go to the hospital to check the cause. After the child wakes up, you can feed the child some food such as noodle soup, but do not feed too much. If the baby cannot eat, you can go to the hospital for water infusion to replenish energy to prevent dehydration. If the child is in good spirits and does not cry, he or she can be observed at home.
