Electromagnetic Sensor-Guided Enteral Access Systems: A Literature Review

Area of Science:

• Medical Devices
• Gastroenterology
• Critical Care Nutrition

Background:

• Enteral feeding is crucial for acutely ill patients unable to swallow.
• Early enteral nutrition is linked to reduced mortality and hospital stay.
• Conventional nasoenteric tubes risk misplacement, leading to complications like pneumothorax and delayed feeding.

Purpose of the Study:

• To evaluate electromagnetic sensor-guided enteral access systems (EMS-EAS) for nasoenteric feeding tube placement.
• To determine if EMS-EAS overcomes challenges associated with conventional tube placement and confirmation.

Main Methods:

• A literature search was conducted on Medline and Embase databases.
• Studies focused on electromagnetic or magnetic guidance systems for feeding tubes in adults.
• Data on placement accuracy, complications, and time to feeding were analyzed.

Main Results:

• Electromagnetic sensor-guided enteral access systems (EMS-EAS) showed agreement with radiographic confirmation.
• EMS-EAS virtually eliminated misplacement risks; pneumothorax was not reported.
• Studies indicated fewer X-rays and reduced time to initiate feeding compared to blind placement.

Conclusions:

• EMS-EAS significantly reduces complications from nasoenteric feeding tube misplacement.
• Widespread adoption of EMS-EAS could improve mortality, morbidity, patient experience, and cost-effectiveness.
