目的 探讨江苏省三级医院ICU护士对中华护理学会标准委员会2021年发布的《成人有创机械通气气道内吸引技术操作（T/CNAS 10─2020）》标准的执行情况。方法 采用方便抽样法，于2023年6月采用自制问卷，通过问卷星小程序开展横断面调查，调查护士在气道内吸引操作中的评估、计划、实施、评价4个方面的表现。结果 共有614名来自三级医院ICU的护士参与调查。通过多元线性回归分析发现，在气道内吸引评估维度中，护士的能级与其能力呈负相关（B=-0.396，P=0.001）；在气道内吸引计划维度中，女性优于男性（P=0.023）；在实施维度和总得分中，最高学历与其能力呈负相关（B=-1.016，P=0.005；B=-1.746，P=0.038）；而专科年限在气道内吸引评价维度中呈正相关（B=0.149，P=0.003）。结论 江苏省ICU护士团体标准的执行情况存在差异，建议加强高能级护士的技能巩固培训，提升男护士的计划能力，并为高学历护士提供更多临床实践机会，以促进理论与实践相结合。

Objective This study evaluated ICU nurses in tertiary hospitals in Jiangsu Province on their implementation of the 2021 “Adult Invasive Mechanical Ventilation Endotracheal Suctioning Technique Standard （T/CNAS 10-2020）” issued by the Chinese Nursing Association. Methods A cross-sectional survey was conducted using a self-developed questionnaire distributed through the “Questionnaire Star” applet，employing a convenience sampling method. The survey explored four aspects of the endotracheal suctioning（ETS） process，including assessment，planning，implementation，and evaluation. Results A total of 614 ICU nurses from tertiary hospitals participated in the survey. Multiple stepwise linear regression analysis revealed several significant findings：nurses’ competency level was negatively correlated with ETS assessment（B=-0.396，P=0.001）；in the airway suctioning planning dimension，females performed better than males（P=0.023）；and the highest educational level was negatively correlated with both ETS implementation and total score（B=-1.016，P=0.005；B=-1.746，P=0.038）. Conversely，years of specialized experience was positively correlated with ETS evaluation ability（B=0.149，P=0.003）. Conclusion Gaps remain in the implementation of ICU nurses in Jiangsu Province regarding the ETS standard. It is recommended to strengthen skill reinforcement training for high-competency nurses，improve planning abilities among male nurses，and provide nurses with advanced degrees more opportunities for clinical practice to better integrate theoretical knowledge with practical application.
