Background
Pneumonia asthma (infantile pneumonia) is the most common pediatric disease and is the first cause of death in children. Clinically, fever, cough, expectoration, shortness of breath and nasal flaring are taken as main symptoms, and serious symptoms can be seen such as shoulder raising by opening mouth, dyspnea, pale complexion, blue and purple lips and the like; common cold (acute upper respiratory infection) is a common disease of children, accounts for 70-80% of the outpatient clinic amount of the children, and can be caused all the year round due to the congenital weakness of the children and the susceptibility to wind evil. The peak of the disease occurs from 6 months to 3 years old, more than 90 percent of pathogenic microorganisms are used as viruses, the fever is generally repeated for about 3 days, the fever is obvious at night, the children patients are difficult to take the medicine, the pain is aggravated by transfusion, and parents suffer from double troubles of physical and mental activities; diarrhea (diarrheal disease) the diarrheal disease is a group of diseases caused by multiple pathogens and multiple factors, and is one of the important causes of malnutrition, growth and development disorder and death of children. In China, the mortality rate of the diarrhea is obviously reduced due to the improvement of the nutritional status and the medical conditions of children, but the morbidity is still high, particularly in areas with poor conditions, so the diarrhea is one of the key diseases for prevention and treatment in China.
The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists, is the mark of the physicians, and the modern medicine is the invention of the stethoscope.
