Innovating Verification of Nasogastric Tube Insertion to Address Clinical Misplacement and Displacement.
The VeriFeed prototype presents two design modifications to the current nasogastric tube: (1) an invertible cone at the distal end of the feeding tube and (2) an accessory wire coated with 100% hypromellose (HPMC) for gastric acid indication (present inside diameter of tube).
Nasogastric tubes (NGT, Class II medical device) are used for administration of food/medication and gastric decompression. Nationally, approximately 120,000 preterm infants (born prior to 34 weeks of gestation) in the US require the use of an NGT due to partial development of essential reflexes and lack of coordination/strength to support feeding. Verification methods in practice address the clinical problem of the significant risk of misplacement or displacement (may increase risk of injury/harm to patient) of NGT in insertion and use. Current gold standard practice to verify the placement of NGT in the selected population of neonates requires the use of radiography; subsequently increasing (1) time endured per intervention, (2) cost of care, and (3) risk to patient safety. Implications to replace the existing standard may cater to support accessibility of care while protecting the integrity of patient safety in delivery of intervention.
