The study shows significant correlations between oral-mucosal pressure ulcers and restraint use, level of consciousness, and the abundance of specific bacteria in the oral cavity. Frequent monitoring of mechanical pressure on the oral mucosa and oral microorganisms can effectively prevent the development of oral-mucosal pressure ulcers in intubated patients.
Purpose: This study was performed to determine the relationship between oral-mucosal pressure ulcer (PU) stage and mechanical conditions and individual susceptibility in intubated patients. Methods: We collected 80 patient-days data from an intensive care unit of a 700-bed hospital in Korea. We analyzed oral-mucosal PUs, medical records, amount of saliva, and oral mucosal swabs. Bacterial abundance was enumerated by real-time polymerase chain reaction. The chi(2) or Fisher's exact test, t-test or Mann-Whitney U test, and Spearman's rho correlation analysis were performed. Results: The incidence of overall oral-mucosal PUs was 31.3%, and in the maxillary and mandibular sites were 16.3% and 26.3%, respectively. There were significant correlations between the maxillary site PU stage and restraint use (r = .43, p < .001), albumin level (r = -.22, p = .046), and relative abundance of P. aeruginosa (r = .45, p < .001) and S. aureus (r = -.24, p = .033). In the mandibular sites, there were significant correlations between PU stage and restraint use (r = .30, p = .008), level of consciousness (r = .31, p = .005), and relative abundance of P. aeruginosa (r = .25, p = .028) and S. pneumoniae (r = .22, p = .046). Conclusions: Frequent monitoring and repositioning the mechanical pressure on the oral-mucosa could be an effective preventive strategy against the development and advancement of oral-mucosal PUs. Additionally, monitoring the oral microorganisms can prevent advanced stage oral-mucosal PUs in intubated patients.
