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.
