The nose-ear-xiphoid (NEX) method for predicting gastric tube insertion length in children should be phased out, according to US researchers from Indiana University’s school of nursing.
They compared three methods: NEX, nose-ear-mid-umbilicus (NEMU), and age-related, height-based (ARHB) in 276 children who were randomly assigned to one of the three.
ARHB and NEMU were found to be significantly more accurate than NEX.
Writing in the Journal for Specialists in Pediatric Nursing, the authors said: “NEX should no longer be used as a gastric tube insertion-length predictor.”
