Nosocomial Infection

Introduction
Of significant concern is the prevalence of nosocomial infection in acutely and critically ill patients. The mouth usually provides entry for life prolonging interventions, such as endotracheal intubation for ventilation and orogastric tubes for enteral nutrition in the ICU. These interventions unfortunately require the patient to maintain an open mouth and impair the natural airway defenses. This vulnerable position, in combination with other treatments, can contribute to a fast deteriorating oral condition and a dependence on nursing to alleviate tube-related discomfort, thirst, oral lesions and the accumulation of saliva, sputum and oral bacteria. Colonization of the oropharynx is a critical factor in the development of nosocomial …show more content…

Cost-effective oral hygiene may result in improved oral health and comfort in the critically ill. To date, there are few literature reviews by Dental Healthcare Professionals combining the different methods and strategies for adequate oral hygiene measures and protocol of care to be routinely followed for …show more content…

Elderly institutionalized, chronic obstructive pulmonary disease, and ICU patients are at higher risk of periodontal colonization by nosocomial pathogens because of difficulties in oral hygiene, changes in salivary properties, and reduction of anaerobic flora.7, 8, 9 In ICU patients Oropharyngeal colonization by aerobic pathogens occurs very rapidly because of incumbent changes in antibacterial resistance, i.e., decreased immunoglobin (Ig)-A salivary content, reduced salivary secretion, mechanical injury induced by nasogastric and endotracheal tubes and mucosal desiccation. This in turn facilitates the mucosal adhesion of aerobic bacilli and allows bacterial multiplication and speedy growth on pharyngeal mucosa.10, 11 Oral Plaque harbors microorganisms in the sequence of initial colonization and represents an additional source of nosocomial colonization and infections in ICU patients. Plaque inside oral cavity is a dynamic and conglomerate system that associates microbes ingrained in an extracellular pattern. This mainly results from encampment and amplification of aerobic, anaerobic, and filamentous microorganisms on the surfaces of teeth, dental prostheses and soft tissues. Dental plaque is predominately located on the subgingival and supragingival surfaces of the teeth, but without
