Placement of Novel Endoscopic Enteral Feeding Tube (LEGEND)

5 septembre 2018 mis à jour par: Nestlé

Placement of Novel Endoscopic Enteral Feeding Tube - A Feasibility Study

The aim of this study is to evaluate the technical feasibility of the new tube placement technology in healthy volunteers and, if proven feasible, in critically ill patients requiring placement of a feeding tube.

Aperçu de l'étude

Statut

Résilié

Intervention / Traitement

Description détaillée

Enteral feeding is the preferred route of nutrient delivery in hospitalized patients who cannot eat sufficiently. Placement of enteral feeding tubes carries a risk of misplacement especially in patients who are unable to fully collaborate during the tube placement due to neurological impairment and/or the presence of an artificial airway. The misplacement of a feeding tube in the airways has a high risk of severe complications, including pneumonia, mechanical damage of airways and the lung, and death. The verification of correct tube placement can be done using radiography, or interventions aimed at confirming the location of the tube tip by aspiration of gastric contents, and by auscultation during injection of air.

Approximately 20-25 % of patients treated in intensive care units are likely to need placement of a feeding tube, while undergoing mechanical ventilation and having an artificial airway. This high risk patient group would benefit from technologies allowing direct visualization of tube placement. It is also expected that direct visualization of tube placement will allow confirmation of tube placement and therefore eliminate the need of radiography (radiation).
