Endotracheal suctioning of the adult intubated patient--what is the evidence?
Intubated patients may be unable to adequately cough up secretions. Endotracheal suctioning is therefore important in order to reduce the risk of consolidation and atelectasis that may lead to inadequate ventilation. The suction procedure is associated with complications and risks including bleeding, infection, atelectasis, hypoxemia, cardiovascular instability, elevated intracranial pressure, and may also cause lesions in the tracheal mucosa. The aim of this article was to review the available literature regarding endotracheal suctioning of adult intubated intensive care patients and to provide evidence-based recommendations The major recommendations are suctioning only when necessary, using a suction catheter occluding less than half the lumen of the endotracheal tube, using the lowest possible suction pressure, inserting the catheter no further than carina, suctioning no longer than 15s, performing continuous rather than intermittent suctioning, avoiding saline lavage, providing hyperoxygenation before and after the suction procedure, providing hyperinflation combined with hyperoxygenation on a non-routine basis, always using aseptic technique, and using either closed or open suction systems.
