Neutrophils are a type of white blood cells and the most numerous phagocytic cells in the blood. High neutrophils are generally common in physiological hypertension, infection or inflammation, massive trauma, acute blood loss or hemolysis, endocrine and metabolic disorders, immune diseases, malignant tumors and certain blood diseases, etc. Most commonly, they are caused by infection or inflammation. If the neutrophils are high, we should first determine the cause, and then take targeted response. 1, the cause 1, physiological high: such as pain, hot and cold stimulation, emotional excitement, strenuous exercise or pregnancy state can make neutrophils temporarily high, belong to the normal physiological reaction; 2, infection or inflammation: neutrophil elevation is the most common cause of infection and inflammation, can be bacteria, viruses or fungi and other pathogens infection, respiratory tract, digestive tract, urinary system, reproductive system and other systems and organs Inflammation can cause high neutrophils; 3, large trauma: If there is large trauma, large surgical trauma and extensive burns, etc., so that the body has large tissue damage, will also cause high neutrophils; 4, acute blood loss or hemolysis: generally in the occurrence of thoracic hemorrhage, abdominal hemorrhage, intracranial hemorrhage or visceral rupture and other acute blood loss or hemolysis, can appear high neutrophils; 5. Endocrine and metabolic disorders: such as diabetic acidosis, thyroid crisis, hepatic encephalopathy and other endocrine and metabolic disorders can also lead to high neutrophils; 6, immune diseases: such as rheumatic fever, rheumatoid arthritis and other skeletal joint diseases or skin rashes, rashes and other skin type diseases, are autoimmune diseases, which can lead to increased neutrophils; 7, malignant tumors and certain Blood diseases: malignant tumors such as lung cancer, liver cancer, kidney cancer, and blood diseases such as leukemia, multiple myeloma, etc., will have high neutrophil performance; 8, other: transfusion reaction, allergic reaction, poisoning reaction and tissue necrosis, such as pulmonary infarction, myocardial infarction, drug side effects and many other conditions, can cause high neutrophils. Treatment 1, physiological high: after the elimination of stimulation can return to normal, no special treatment is needed; 2, infection or inflammation: when there is infection or inflammation, anti-infection treatment is needed to eliminate inflammation, usually need to clarify the pathogens after the targeted use of drugs, such as quinolones, cephalosporins and other antibiotics, such as septic infection, if necessary, drainage treatment; 3, large trauma, acute blood loss or hemolysis. For large trauma, acute blood loss or hemolysis, timely hemostatic measures should be taken, and if necessary, transfusion therapy or anti-hemolytic treatment; 4, endocrine and metabolic disorders: neutrophil high caused by endocrine and metabolic disorders, and physical discomfort, need to timely control the disease and correct metabolic disorders; 5, immune diseases: for immune diseases usually use targeted hormonal drugs for treatment, if If the joint problem is serious, joint orthopedic or replacement surgery for medical treatment; 6, malignant tumors and certain blood diseases: malignant tumors and blood diseases are more complex, should be under the guidance of doctors, the primary tumor chemotherapy, or surgery to remove the way, for targeted treatment. Third, precautions appear neutrophil elevation, if it is caused by infection, inflammation, should pay attention to avoid staying up late and stimulating diet to prevent aggravation, if the symptoms are more serious, such as the emergence of septic infection, etc., should promptly seek medical attention.
