密闭式吸痰的研究进展

Research progress on closed endotraeheal suctioning

接受机械通气的患者目前多采用开放式吸痰，容易合并呼吸机相关性肺炎。近年来，密闭式吸痰广泛应用于临床，与开放式吸痰方法相比，密闭式吸痰能够减少吸痰导致的气道污染，肺组织再损伤，降低呼吸机相关性肺炎发生率。

Patients receiving mechanical ventilation （MV） can contract ventilator-associated pneumonia （VAP） because of open endotraeheal suetioning. Closed endotraeheal suctioning was applied widely in clinical. Compared with open endotracheal suctioning, it could reduce airway pollution, re - injury of the lung tissue and the occurrence rate of VAP.
