Bedside method for placing small bowel feeding tubes in critically ill patients. A prospective study

Area of Science:

• Critical Care Medicine
• Gastroenterology
• Clinical Nutrition

Background:

• Enteral nutrition is crucial for critically ill patients, maintaining gut function and preventing sepsis.
• Impaired gastric emptying is common in critical illness, increasing risks of aspiration and feeding intolerance.
• Small bowel feeding can bypass gastric issues, but tube placement can be challenging.

Purpose of the Study:

• To describe and evaluate a simple bedside technique for the successful placement of small bowel feeding tubes.
• To assess the efficacy and accuracy of this technique in critically ill patients.
• To identify reliable and cost-effective methods for confirming post-pyloric tube placement.

Main Methods:

• A bedside technique was employed for small bowel feeding tube insertion in critically ill patients.
• Placement success rates, tube locations, and procedure times were recorded.
• Abdominal roentgenograms were used for initial localization, with bile aspiration, pH changes, and blue dye injection used for confirmation.

Main Results:

• The technique achieved a 92% success rate in placing 213 out of 231 feeding tubes.
• Tubes were successfully placed in the duodenum (3%), second portion (25%), third portion (47%), and proximal jejunum (17%).
• Abdominal roentgenograms had a 6% failure rate in accurate localization; bile aspiration, pH testing, and dye injection proved accurate and cost-effective.

Conclusions:

• The described bedside technique offers a highly successful method for placing small bowel feeding tubes in critically ill patients.
• This approach helps mitigate complications arising from impaired gastric emptying, facilitating optimal enteral nutrition.
• Simple methods like bile aspiration, pH monitoring, and dye injection are reliable for confirming post-pyloric tube placement.
