Enteral Nutrition
Conditions
Brief summary
This is a single center, non-randomized feasibility clinical evaluation that is designed to affirm the safety of the ENVUE™ System guidance during the placement of the ENvizion Medical™ enteral feeding tubes.
Detailed description
Enteral nutrition is the preferred route for the provision of nutritional support in most critical ill patients with functional gastrointestinal tract. Achieving early enteral nutrition (EN) in critically ill patients is associated with fewer major complications, reduced mortality and length of hospital stay, and significant cost savings. It is estimated that approximately 1.2 million feeding tubes are placed blindly each year in the United States alone. Despite the obvious advantages of the enteral tube feeding, inadvertent placement of Enteral Feeding Tube (EFT) into the airway is relatively common and can result in significant pulmonary injury including pneumothorax and pneumonia. Airway misplacement occurs in 1.2- 4 % of blind EFT insertions, with 0.2 to 1.2% of all the feeding tube placements cause pulmonary complications to patients. The gold standard for detecting inadvertent placement of a feeding tube in the lungs is radiography. However, because of its cost, possible delay of feedings while waiting for radiography, and risk for radiation exposure, clinicians continue to seek for alternative methods to confirm correct placement. All the above mentioned, emphasizes the fact that safe and effective delivery of nasoenteral tube feedings requires assurance that the feeding tube tip is in a proper position. The ENVUE™ System is an electromagnetic tracking system which tracks the path of the feeding tube during placement. The benefit of the system when EFT is misdirected into the pulmonary system is a real-time visual tracing, which may prompt users to withdraw the tube and reinsert it.
Interventions
The ENvizion Medical™ ENVUE™ System is designed to aid qualified operators in the placement of the ENvizion Medical™ Enteral Feeding Tube™ into the stomach or small intestine.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Successfully Placed Enteral Feeding Tube | During procedure visit | Enteral tube (EFT) can be placed in the correct anatomical position without occurrence of guidance-related adverse events. Procedure success was evaluated by comparing tube tip location according to the ENVUE System and abdominal and/or thoracic X-Ray. Guidance-related AEs were evaluated through the documentation of any guidance-related serious adverse events (SAE) or adverse events (AE) occurring during a subject's participation in the study. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Total Number of Placement Attempts | During procedure visit | Number of placement attempts was evaluated by number of replacement and repositioning events, as defined below: * Replacement: Complete removal of the tube from the patient or retraction above the level of the pharynx followed by reinsertion * Repositioning: Changing position of tube without complete removal of the tube |
| Number of Retrograde Tube Migration Events | During follow-up visit (20-48 hours post tube placement) | Tube Migration was defined as: Retrograde migration from desired placement position. |

Outcome results
Number of Participants With Successfully Placed Enteral Feeding Tube
Enteral tube (EFT) can be placed in the correct anatomical position without occurrence of guidance-related adverse events. Procedure success was evaluated by comparing tube tip location according to the ENVUE System and abdominal and/or thoracic X-Ray. Guidance-related AEs were evaluated through the documentation of any guidance-related serious adverse events (SAE) or adverse events (AE) occurring during a subject's participation in the study.
