Respiratory tract bacterial infections are usually first empirically treated with broad-spectrum antimicrobial drugs, such as ceftriaxone and levofloxacin; if this is not effective, biological samples (e.g., sputum) need to be retained, and sensitive antimicrobial drugs are selected based on the results of drug sensitization. Respiratory tract infections bacterial infections, including upper respiratory tract infections (e.g., infections of the nasopharynx and throat) and lower respiratory tract infections (infections of the trachea, bronchus, and lungs), common pathogens include hemolytic streptococcus, Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma. At the initial stage of the disease, broad-spectrum antimicrobial drugs, such as ceftriaxone, cefoperazone, azithromycin, levofloxacin and other drugs, are often chosen, and sputum culture and drug sensitivity tests are performed at the same time. If the efficacy of the drug is not exact, according to the results of drug sensitivity, choose sensitive antibacterial drugs. Respiratory bacterial infections should go to the hospital in a timely manner, under the guidance of the doctor to choose the appropriate treatment program, do not private blind treatment, so as not to delay the condition.
