How is lobar pneumonia caused? In fact, any bacteria can cause lobar pneumonia, such as Mycoplasma, Streptococcus pneumoniae, Streptococcus hemolyticus, etc. Lobar pneumonia is an acute inflammatory disease characterized by diffuse fibrinous exudation in the alveoli, with an acute onset and rapid spread to a segment of the lung or the entire lobe. Children may present with high fever, usually above 39 degrees; violent cough, some with dry cough, some with sputum; chills; anorexia; lethargy and poor mental status; some children have gastrointestinal reactions such as nausea, vomiting and diarrhea; and some children with atypical symptoms and prolonged cough. Severely ill children may have respiratory difficulties or even complications of infectious shock. Lobar pneumonia is a condition in which the entire lobe of the lung becomes diseased, often in combination with pleurisy and pleural effusion, and can be life-threatening if left untreated. Necrosis and liquefaction of the affected lung tissue can form a lung abscess, and when the pleural lesion is severe it can develop into fibrinous purulent pleurisy or even an abscess chest. If the inflammation is not cleared in time, it can also become mechanized and eventually block the bronchi, leading to pulmonary atelectasis. When a child develops atelectasis, he or she is often short of breath and has limited movement. Once diagnosed, lobar pneumonia requires hospitalization. Treatment of lobar pneumonia is mostly conservative and most children need to be hospitalized for more than half a month before they are likely to recover. Nowadays, many large hospitals have developed bronchoscopic interventions in pediatrics or otorhinolaryngology, where the bronchoscope is inserted through the child’s nasal cavity to directly reach the lesion and remove the phlegm plug directly through the lower mirror, solving the disease at its root and shortening the course of the disease. Bronchoscopy is also a very effective method for children who develop atelectasis. Pneumonia is transmissible and many parents vaccinate their children to prevent pneumonia, but vaccines only prevent streptococcal infections, and the bacteria that cause pneumonia to occur are too diverse to prevent. The occurrence of pediatric pneumonia is related to the child’s physical condition and pathogens. Therefore, parents should try to avoid taking their children to public places, ventilate their homes often, give their children more water in dry weather, pay attention to the timely increase and decrease of clothing with temperature changes, supplement vitamins and reasonable nutrition during the high pneumonia stage. If your child has poor health and has recurrent asthma or pneumonia, it is not recommended to go to kindergarten during this season. Because of the rapid onset of pneumonia, once your child has a fever, chronic cough, headache or poor spirit, you should go to a regular hospital and have a chest X-ray related examination done in a timely manner to achieve early detection and treatment to avoid missing the best treatment.
