Chemical Oral Health care and Aspiration Pneumonia (AP)in Elderly Patients:A Systematic Literature Review

摘要

To thoroughly review the literature on chemical oral health care interventions in the elderly without mechanical ventilation and the denouement of AP. The prevention of AP in the elderly using oral health care seems to play an important role reducing the microorganisms thatcause of the lung infection. The intervention studies in the elderly were searched by Pubmed, Web of Science, Cochrane Library and EMBASE. The method of evaluated processing the quality was independently shown in the journals by two other authors. The intervention studies were included in six studies. Four studies showed that oral care plus chlorhexidine gluconate (variable in concentration 0.05%, 0.12% and 0.2%) to improve of oral care reducing the risk of AP. Two studies showed that cetylpyridinium chloride, decreased the number of oral anaerobic bacteria that caused a lower respiratory tract infection. As reported by the results, the current thorough review of the literature, chemical oral health care, consisting of chlorhexidine gluconate, cetylpyridinium chloride, seem to be the best chemical mouthwash agent in reducing the risk of developing AP.
