I believe most people are unfamiliar with whistle blower pneumonia, and this may be the first time many people have heard of this type of pneumonia. But this whistle blower pneumonia is indeed a real thing. It’s just that our knowledge of it is somewhat lacking. Today I will give you an introduction to this whistle blower pneumonia. Whistler pneumonia, also known as whistler-associated pneumonia, it refers to the pneumonia that occurs after 48 hours of tracheal intubation to 48 hours after extubation when the patient must be kept alive by a whistler because of the disease, which has a high incidence and is a refractory pneumonia. Once the disease is present it is usually serious and can even cause death. Whistler pneumonia is caused by a hospital-acquired infection, which means that whistler pneumonia is associated with human factors. So it can be avoided through prevention, the preventive measures are: a. Strengthen the management of medical and nursing staff, fully strengthen the aseptic awareness of medical and nursing staff. 1, diligent hand washing, the hands of health care workers is an important way to spread VAP pathogens; 2, shared medical equipment sterilization can not be ignored, contaminated devices such as whistling machines, fibrinoscopes, nebulizers, etc. is another important way of transmission of VAP. 3, the whistle syncytial virus (RSV) patients and pathogen carriers to take isolation measures; 4, strengthen the management of the ward to avoid the outside environment of the abnormal flora easy to invade the lower whistle tract and complications of infection. Second, reduce or eliminate the colonization and inhalation of pathogenic bacteria in the oropharynx and stomach cavity. 1, strengthen airway management, especially the upper whistle tract, the upper whistle tract is an important part of the non-specific defense function of the whistle system, can protect the trachea and bronchial mucosa, maintain the physiological function of the bronchial epithelial cells, promote normal cilia movement, remove dust particles, microorganisms, harmful substances and whistle secretions in the inhaled air, to a certain extent, play a role in the prevention of lung infection physiological security. 2, strengthen the management of the oropharynx, the rapid multiplication of bacteria in the oral cavity, tracheal tube to prevent the closure of the epiglottis, bacteria with oropharyngeal secretions from around the catheter through the vocal tract under the leakage into the whistle can cause the lower migration of bacteria in the oropharynx and increase the incidence of VAP. Therefore, we must pay attention to the cleanliness of the oropharynx. 3, control the reflux of gastric contents, patients receiving mechanical ventilation to adopt a semi-recumbent position, may be a simple and effective way to reduce the reflux of gastric contents into the lower whistle. 4.Strengthen the body’s immune defense function and use antibiotics reasonably. Impaired systemic or local immune defense function is one of the reasons why hospitalized patients are prone to pneumonia. As long as you can do these, you can greatly reduce the incidence of whistle machine pneumonia.
