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.

研究结果发现，在实际观察护理人员执行口腔护理和护理人员自我报告口腔护理使用的清洁工具与溶液，口腔棉棒与海绵洁牙棒是气管内管留置病人口腔护理主要的清洁工具，清洁溶液主要选择以自来水或开水稀释的漱口水；口腔护理步骤平均得分百分比为74.2％；因护理人员所属加护病房性质不同，护理人员选择口腔护理之清洁工具、清洁溶液、清洁溶液使用方式及气管内管固定方式有所不同；护理人员年龄越年长，其执行口腔护理步骤完整率越高；内科系加护病房护理人员执行口腔护理步骤的完整性显著高於外科系加护病房护理人员。
