Pneumonia due to Klebsiella pneumoniae infection is more serious and is often seen in elderly and malnourished patients, or in people who already have chronic lung disease, and is caused by Klebsiella pneumoniae infection. The infection is characterized by chills, high fever, cough, chest pain, pus and brick-red jelly sputum, and in severe cases, even some respiratory failure or peripheral circulation failure, and can easily lead to lung abscess, abscess chest, pericarditis, or meningitis. Once the infection of Klebsiella pneumoniae occurs, it must be hospitalized quickly for treatment, Klebsiella pneumoniae is more resistant to drugs and has a higher mortality rate. It is generally recommended to use fourth-generation cephalosporin antibiotics for anti-inflammatory treatment, or aminoglycoside antibiotics or quinolone antibiotics, which are more effective. If the cough and sputum are serious, it is best to nebulize and inhale bronchodilators and phlegm-reducing drugs.
