A importância da atuação odontológica em pacientes internados em unidade de terapia intensiva

Abstract

In the intensive care unit, the nosocomial respiratory infection is responsible for high rates of morbidity, mortality and expressive increase in hospitals costs. Its establishment feels more commonly by the aspiration of the content present within the mouth and the pharynx. Thus we intended to review the literature on the participation of the oral condition in the establishment of the nosocomial respiratory infection. Deficient oral hygiene is common in patients under intensive care, which provides the colonization of oral biofilm for pathogenic microorganisms, especially for respiratory pathogens. The studies clearly show that the amount of oral biofilm in patients under intensive care increases according to period hospitalization meanwhile there also is an increase in respiratory pathogens. That colonizes the oral biofilm. This biofilm is an important resource of pathogens in patients under intensive care. In spite of well-established hypotheses that narrow down the relationships between lung infections and the oral condition, the studies are not still completely defined. However, due to strong possibilities that these hypotheses are true, it is necessary to have and maintain the oral health, in addition to more integration of dentistry and of Medicine, seeking patients' global treatment, the prevention of diseases, and more humanization at the intensive care unit.
