Nasogastric tube insertion

The placement of nasogastric feeding tubes is a common used technique whereby a correct tip position in the stomach is essential in administering tube feeding in a safe way. Until now the NEX method (distance nose - earlobe - xiphoid) is still the gold standard to determine the insertion length of a nasogastric tube but several experimental studies, which also suggested alternative methods, demonstrated that the NEX method is not reliable.

Based on these results of a recently conducted study, an alternative method, the CoNEX, was developed which has subsequently been tested in a pilot study. This method resulted in promising results with 100% correctly positioned nasogastric tubes in the stomach. Consequently, this method contributes to a safe and efficient placement of nasogastric tubes. The likelihood in obtaining gastric aspirate also increased in comparison with the other alternative methods.
