Low neutrophils in babies may be due to physiological and pathological factors. Pathological factors include viral infections, drug effects, and immune system disorders. Parents should take their babies to the hospital for a detailed examination and targeted treatment in a timely manner. Common causes a. Physiological factors neutrophils and lymphocytes make up white blood cells. Baby in infancy, lymphocyte development is fast, so more lymphocytes, neutrophils low is a common situation, not abnormal. Second, the pathological factors 1, virus infection: neutrophils are the main components of white blood cells, baby infected with a virus, white blood cell count is significantly low, neutrophils will also appear low phenomenon; 2, drug influence: baby applied immunosuppressive or cytotoxic drugs, such as taking cyclophosphamide, will cause neutrophils and white blood cell count is significantly low phenomenon; 3, immune system disorders. The baby’s body resistance is low, due to viral and bacterial infections cause disorders in the immune system, resulting in a decrease in hematopoietic cells, there will be low neutrophils. Treatment 1, due to viral infections resulting in a decline in neutrophil values, you need to take antiviral treatment, neutrophils can rise to normal levels after improvement; 2, children with high fever symptoms, confirmed infection, anti-inflammatory treatment should be carried out under the guidance of a doctor, first use cephalosporin antibiotics, such as cefadroxil, cefadroxil, etc. to control symptoms; at the same time to find the foci of infection, choose sensitive antibiotics The baby’s neutrophils, if rapidly declining, can choose to transfuse blood or isolate white blood cells to improve body resistance and speed up the recovery from inflammation. Note 1, neutrophil low baby, immune function is also lower, prone to infection, pay attention to avoid cold, and stop using drugs that affect granulocytes, such as antipyretic and analgesic drugs; 2, the baby in the treatment period to pay attention to reasonable supplementation, adequate rest, can ensure to improve the baby’s resistance, reduce the chances of low central granulocytes.
