Although previous studies failed to clearly demonstrate that NSI is
useful and effective, NSI is widely used by nurses in clinical practice
[3,4,19]. A study performed by Chau et al [20] reported that nurses
continue to use NSI in clinical practice, although compliance with the
current evidence-based guidelines is high. Thus, NSI usage before endotracheal suctioning remains a controversial issue. Furthermore,
new studies that investigated the effects of NSI were not included in
previous systematic reviews [21-24]. As the evidence obtained through
scientific methods is converted into practice, clinicians' views and own
experiences are very important. Accordingly, the aim of the present
study is to systematically review studies that investigated the effect of
using NSI before endotracheal suctioning on sputum amount, patient
oxygenation, hemodynamics, and the development of pulmonary infection.
In addition, this study aims to evaluate NSI use for adult patients by
intensive care nurses and assess the views of nurses on this topic.
