Assessment by finite element analysis modelling of tissue strains associated with the use of two different nasogastric tube securement devices.

ABSTRACT:

Objectives

Nasogastric tube use can lead to pressure injury. Some nasogastric tube securement devices (NG-SD) include hard plastic components. In the current study, we assessed the differences in strain profiles for two NG-SD, one with hard segments and one without hard segments, using finite element analysis (FEA) to measure strain and deformation occurring at the nasogastric tube-tissue interface.

Methods

FEA in silico models of devices were based on device mechanical test data and clinically relevant placements. Peak strain values were determined by modelling different scenarios using Abaqus software whereby the tubing is moved during wear.

Results

The modelling showed peak strains ranging from 52% to 434% for the two NG-SD depending on the tubing placement
