The results showed that cotton swab and foam swab were the main oral care cleaning equipment used for oral intubated patients according to observations of ICU nurses performing oral care and self-reported questionnaires of ICU nurses. The cleaning solution was mainly dilute mouthwash. The mean correct rate was 72.4% in procedures of oral care. Due to the different characteristics of ICUs, the ICU nurses chose different cleaning equipment, cleaning solutions, methods of using cleaning solution, and oral endotracheal tube securement methods. Older age of the ICU nurses, was associated with more complete oral care. The completeness of performing oral care by the ICU nurses in medical ICU was significantly higher than that by nurses in surgical ICU.
