A study on the safety of Nursing Performance Audit endotracheal suctioning

本研究的目的是重新评估在临床环境中经常在高压下进行的气管内吸引，以确定对患者安全、有效和舒适的技术。在初步研究中，使用模拟痰液检测了吸入管内压力与吸入量之间的关系。此外，估计了健康志愿者自咳痰中纤毛柱状细胞的数量。作为本研究的第一部分，在文献报道的最小和最大吸入压力下吸入的痰中测定纤毛柱状细胞。其次，大鼠在高吸压下直接吸入。最后，选取需要气管内吸引的病例进行病例分析。对患者进行高压吸痰，并对吸出的痰进行镜检分析。综合上述调查结果表明，只要仔细考虑患者的状态，并严格控制与手术本身相关的各种条件，在高压下进行气管内吸引而不造成呼吸道粘膜损伤是可能的。

Nursing Performance Audit A study on the safety of endotracheal suctioningThe purpose of this study was to reevaluate endotracheal suctioning which is regularly performed under high pressure in the clinical setting, to determine techniques which are safe, effective, and comfortable for the patient.In a preliminary study, the relationship between pressure within the suction tube and suction volume was examined using simulated sputum. Additionally, quantities of ciliated columnar cells in self-expectorated sputum were estimated in healthy volunteers. As the first part of this investigation, ciliated columnar cells were determined in sputum aspirated at minimum and maximum suction pressures reported in literature. Secondly, rats were subjected to direct suction at high suction pressure. And last, case studies were made on selected cases requiring endotracheal suctioning. The patients were given high pressure suction, and the aspirated phlegm was subjected to microscopical analysis.Integrating results from the investigation above indicated that it is possible to perform endotracheal suctioning at high pressure without causing mucosal damage to the respiratory tract, provided careful consideration is given to the state of the patient in addition to strict control of the various conditions associated with the procedure itself.
