Clinical Progress Research on Oral Care for Patients with Critical Illness

In the nursing of patients with critical illness, the oral health of patients will be seriously affected because it is difficult for patients to complete oral care independently. Various microbial pathogens are deposited in patient biofilms as well as in oral secretions and are continuously transmitted. Under the condition of positive pressure ventilation, these pathogenic bacteria will enter the lower respiratory tract of patients, leading to nosocomial pneumonia infection in patients. This will not only significantly prolong the ICU stay time of patients, but also increase the mortality rate of patients. Therefore, it is necessary to strengthen the oral care of patients to reduce the number of bacteria in the patient's pharynx. This is one of the important methods to prevent nosocomial pneumonia infection in patients. For this reason, this article studies the clinical progress of oral care for patients with critical illness, in order to provide some reference for relevant personnel.
