Mitigating intubation stress, mucosa injury, and inflammatory response in nasogastric tube intubation via suppression of the NF-κB signaling pathway by engineering a hydration lubrication coating

Abstract

Nasogastric tube (NGT) intubation is a common yet critical clinical procedure. However, complications arising from tube friction result in awful pain and morbidity. Here, we report a straightforward surface modification of slender NGT utilizing highly hydrated micelles that were composed of hyaluronic acid and Pluronic. The strong intermolecular hydrogen bonding facilitated the assembly of the micelles on NGT via a one-step dip coating process. The micelle coating conferred excellent hydrophilic, lubrication, anti-protein adhesive, and biocompatible properties. The in vivo efficacy of the micelle coating in alleviating catheterization irritation and mucosal injury was demonstrated using an NGT intubation model of rabbits. More importantly, compared to the paraffin oil coating (the current clinical means), the micelle coating possessed superior capability to reduce the inflammatory reaction caused by NGT intubation. The underlying mechanism was attributed to the suppression of the TLR4-IKBα-NF-κB inflammatory signaling pathway. This work provides a promising solution for developing lubricant medical coatings.
