Endotracheal suctioning with normal saline is a common
practice in intensive care units (ICUs). However,
research studies have shown conflicting results regarding
this procedure. The literature does not clearly
identify the physiological benefits of this procedure. In
fact, this procedure may result in several life-threatening
complications such as decreased oxygen saturation,
dyspnea, increased intracranial pressure, and pneumonia.
Endotracheal suctioning using saline instillation
should not be a routine practice. This article reviews the
adverse effects of saline instillation during endotracheal
suctioning. It also identifies the role of a critical care
nurse who plays a major role in ventilator care
particularly endotracheal suctioning. Critical care nurses
must identify their role using the synergy model to
evaluate evidence-based practice in promoting safe
patient care and best optimal patient outcomes for these
patients.
