Published and unpublished systematic reviews, rando-
mised controlled trials and comparative studies in any
language that compared 2 techniques and devices to
secure nasogastric tube in patients 18 years old or older were
included in this review. We included studies describing all
types of techniques and devices used to secure nasogastric
tubes. We excluded case reports, editorials, letters, expert
opinions, comments and studies referring only to a
paediatric population because the securing techniques
and devices are different for this group of patients.
