In the South, Northeast and Central Plains, there is a disease in infants and young children that is easy to diagnose but very difficult to treat, laborious and time-consuming: as short as two weeks and as long as two months! This is infantile capillary bronchitis! This disease is more common in infants and toddlers, most often in small children from one to six months old. The clinical manifestations are wheezing, trismus and shortness of breath, with individual children having high fever. I have seen dozens of little ones with this disease. She or he has been hospitalized in several major hospitals, but the outcome has been poor. The outstanding manifestation is wheezing and lungs full of croup, which is very worrying for parents. What is the trick to treat the difficulty? My experience is as follows: 1. Severe children have to be hospitalized, and severe children have to be treated with oxygen. 2, nebulized inhalation treatment: usually choose saline plus Pulmicortin and Gatebutalin, once to three times a day. The course of nebulization has to be seven days to a month, individual differences. 3, such as a viral infection caused by the choice of antiviral western drugs: such as ribavirin injection, interferon. If these two drugs are not effective, you can try thymopentin injection, but must pay attention to whether there is an allergic reaction. Children with mycoplasma infections are treated with Zithromax for three to four days. If combined with bacterial infection, cefprozil or cefixime or amoxicillin can be given. 4.If the economy can, can intravenous injection of human blood gammaglobulin, the course of three days to four days. 5. If the symptoms are not satisfactorily controlled, a short course of prednisone or methylprednisolone can be used for three to four days. Pay attention to fluid supplementation and treat acidosis. Seriously ill patients must be admitted to hospital!
