The problems of damage to facial skin and oral mucus affecting intubated patients have seldom been effectively improved. The purpose of this project was to reduce the incidence of defects in facial skin and oral mucosa integrity in patients with oral endotracheal intubation. The main factors identified by data collection were: 1. Inappropriate endotracheal tube securement. 2. Dry lip mucosa. 3. Pressure points caused by large bite-blocks. 4. Patient's frequent movement of mouth. 5. Allergic reaction caused by adhesive tape. Through the implementation of a new standard for oral endotracheal tube securement and the application of new bite-blocks to deal with the problems mentioned above, the incidence rate of defects in facial skin and oral mucosa integrity decreased from 67% to 25%. The results indicate that the new standard of securement and the new bite-block can help to solve these problems.
