Abstract: ［Abstract］ Objective To investigate the knowledge and practice on endotracheal suctioning of the intubated patients among intensive care nurses. Methods From August 2017 to April 2018， 87 nurses from ICU and EICU were selected to receive the investigation in intensive care units of two hospitals. All participants were surveyed with questionnaires， and 33 nurses of 87 were assessed for on?site ETS operation. Results Most ICU nurses get higher questionnaire scores， but the scores of on?site assessment are lower， which was comparable to the results of knowledge questionnaire， and had relationship with their academic qualifications and working hours. Only 10 nurses （30.3%） had chest auscultation before ETS. Unsatisfactory aseptic operation， frequent sputum suction and no observation of blood pressure after ETS were the main problems. Conclusion Continuing education should be strengthened to suit the practical clinical skills required. These factors may require further supervision and management to prevent them.

摘要： ［摘要］ 目的 调查重症监护护士对吸痰术的认识与实践。方法 研究时间2017年8月~2018年2月，研究人员来自两家医院从事重症监护室工作的护士包括ICU、EICU，共87名护士组成。所有参与者得到问卷调查，并对33名护士在重症患者气管插管后实施气管内吸痰（ETS）操作进行评估。结果 大多数ICU护士获得较高的问卷调查分数，但现场操作考核分数较低，与知识问卷结果脱节，与学历高低以及工作时间有关联。33名护士中，只有10名护士（30.3%）在ETS前患者进行胸部听诊，无菌操作、吸痰来回次数、什么体征观察等是存在的主要问题。结论 应加强护士的继续教育以适合所需的临床实际技能，这些因素可能需要进一步的监督和管理来预防。
