Pediatric pneumonia can usually be cured in about 7 to 10 days with aggressive and routine treatment. However, there are some factors that can slow down the recovery of pediatric disease. 1, abuse of antibiotics: indiscriminate use of antibiotics when the causative organism is not clear makes the child’s flora dysbiosis, resistance to decline, resulting in the emergence of significant drug resistance. This affects the recovery of the disease and may cause the child’s disease to be prolonged, taking half a month to a month or so to get well. 2, allergic lung infection: we use antibiotics basically ineffective, frequent exposure to allergens will also cause the disease to recur. 3, low immunity: children with low immunity also tend to make the disease repeatedly, may be about 14 days after the regular treatment is not able to make the symptoms of the disease well relieved. Therefore, pneumonia must be actively treated: (1) to identify the causative agent, targeted anti-infective treatment. (2) If the diagnosis of pneumonia is confirmed, it is best to carry out direct infusion treatment, oral antimicrobial treatment is not ideal, easy to make the disease more and more serious.
