Absaugung bei intubierten und tracheotomierten Patient*innen

Endotracheal suctioning in intubated or tracheotomized critically ill patients is a daily task of various professional groups in intensive and emergency medicine; however, a German language summary of current evidence is lacking.

The aim is to develop a narrative overview of current evidence on endotracheal suctioning of intubated or tracheotomized patients in the clinical setting.

A literature search was conducted in the databases Cinahl, Cochrane Library, Livivo, and Medline via PubMed by nurses with an academic degree. In addition, a hand search and applying the snowball principle were performed. Following a successful critical appraisal, all English and German language publications addressing endotracheal suctioning in the context of hospital care were included.

A total of 23 full texts were included. After developing 6 main topics on endotracheal suction 19 articles were considered in the reporting. The results showed, among others, that routine deep suctioning once per shift is contraindicated and that the catheter should be advanced no more than 0.5–1 cm beyond the distal end of the tube or tracheal cannula. Closed suction catheters offer advantages, especially for staff protection, although studies are heterogeneous. Further training of staff is obligatory.

Few conclusive studies on endotracheal suction could be found; however, with the available evidence initial conclusions can be drawn which should be considered in, for example, internal standard operating procedures. Further research is needed.
