Fasting practices of enteral nutrition delivery for airway procedures in critically ill adult patients: A scoping review
2022
Overview
There is limited understanding of fasting practices and reported safety concerns for airway procedures in critically ill adults.
To describe fasting practices including safety concerns for airway procedures in critically ill adult patients in the reported literature.
Studies conducted in adult critically ill patients receiving enteral nutrition (EN) and undergoing an airway procedure (endotracheal intubation, endotracheal extubation, and tracheostomy) were included if EN fasting practices and/or prespecified nutrition and clinical outcomes were reported.
A scoping review using the Joanna Briggs Institute methodology was conducted. MEDLINE, Embase, and CINAHL were searched from 2000 to January 19, 2022. Results are presented via narrative synthesis.
Fourteen studies were included, with only one randomised control trial (RCT). Twelve studies reported on fasting practices with varied EN fasting durations (0–34 h) and two reported data on nutrition adequacy. Three studies investigated continued EN in one study arm and four studies minimised fasting duration by including gastric suctioning prior to the airway procedure. Safety concerns primarily related to aspiration events (61%) were reported in nine studies.
In the reported literature, there is wide variation in EN fasting practices for airway procedures in critically ill patients with limited evidence to inform practice.
•EN fasting practices for airway procedures are variable, ranging from 0 to 34 h.•There is a lack of high-quality evidence to guide EN fasting practices in the ICU.•RCTs are needed to explore risks/benefits of reduced fasting for airway procedures.
