When pneumonia and bronchitis occur, the most important treatment measures are divided into two areas. The first aspect is symptomatic treatment; the second aspect is anti-infective treatment. The first empirical use of cephalosporin antibiotics, before the use of antibiotics to do sputum culture and drug sensitivity test. If the cephalosporin antibiotics are more effective, just continue to use them; if they are not effective, select a sensitive antibiotic for treatment according to the results of the drug sensitivity test. For the symptoms of cough and wheezing, cough and phlegm relieving drugs such as Ambroxol hydrochloride or Ambroterol oral solution need to be given, and if there is wheezing, aminophylline can be used. For pneumonia and bronchitis are usually accompanied by fever and high fever, if the temperature exceeds 38.5 degrees, oral ibuprofen suspension is also needed to reduce fever. If the symptoms of pneumonia are severe, nebulized inhalation drugs such as budesonide and terbutaline are also required.
