According to the American College of Gastroenterology, enteral nutrition is the preferred method of feeding when a patient's gut is functional but oral intake is not possible or safe. Short-term enteral access provides a temporary solution for nutritional support, typically lasting less than 30 to 60 days.

Quick Summary

Short-term enteral access involves placing temporary feeding tubes through the nose or mouth to deliver nutrition directly into the GI tract, bypassing oral intake.

Key Points

Duration: Short-term enteral access typically lasts less than 30-60 days and is used for temporary nutritional needs.
Types of Tubes: Common types include nasogastric (NG), nasoduodenal (ND), and nasojejunal (NJ) tubes, which are inserted through the nose or mouth.
Indications: It is used for patients who cannot eat or swallow sufficiently due to conditions like stroke, critical illness, or cancer, but have a functional gut.
Benefits: Compared to IV feeding, it is more physiological, cheaper, and has a lower risk of infection.
Risks: Potential complications include aspiration, tube dislodgement, infection, and gastrointestinal issues.
Placement Confirmation: Correct placement must be confirmed via X-ray or pH testing before feeding begins to prevent severe complications.
Comparison: Short-term access is temporary and minimally invasive, whereas long-term access (e.g., PEG tube) involves surgical placement for prolonged use.

Understanding Short-Term Enteral Access

Short-term enteral access involves the temporary use of a feeding tube to deliver nutrients, fluids, and medications into the stomach or small intestine for patients with a functioning GI tract who cannot eat enough orally. This method is generally used for a few weeks, typically up to four to six weeks. Enteral feeding is often preferred over intravenous nutrition due to potential benefits like a lower infection risk and preservation of gut function.

Types of Short-Term Enteral Feeding Tubes

Temporary feeding tubes are inserted through the nose or mouth into the GI tract. Common types include:

Nasogastric (NG) tube: Placed through the nose into the stomach, used for patients who can tolerate stomach feeding.
Orogastric (OG) tube: Inserted through the mouth into the stomach, often used for infants or sedated patients.
Nasoenteric tubes: Longer tubes placed through the nose, extending into the small intestine, suitable for patients with slow gastric emptying or high aspiration risk. These include nasoduodenal (ND) and nasojejunal (NJ) tubes.

Indications for Short-Term Feeding

Short-term enteral nutrition is used in various situations where oral intake is insufficient or unsafe. Common reasons include difficulty swallowing (dysphagia) from conditions like stroke or neurological disorders, critical illness, post-operative recovery, increased nutritional needs (e.g., burns), or failure to thrive in children.

The Procedure for Placing Enteral Tubes

Nasal or oral tubes are often placed at the bedside. After preparing the patient, the tube is measured, lubricated, and gently inserted. Nasoenteric tube placement may require imaging guidance. Correct tube placement must be verified before use, typically by checking the pH of gastric aspirate or, most reliably, with a chest X-ray. Securing the tube prevents dislodgement.

Benefits and Risks

Short-term enteral access helps maintain nutritional status, supports the immune system, and preserves gut function. Potential risks exist, including aspiration, tube issues (dislodgement, blockage, irritation), and GI problems (nausea, diarrhea).

Short-Term vs. Long-Term Enteral Access

The duration of required nutritional support dictates the type of access. The following table summarizes key differences:


Feature	Short-Term Enteral Access	Long-Term Enteral Access
Duration	Typically less than 4–6 weeks.	Greater than 4–6 weeks; potentially indefinite.
Access Route	Nose or mouth (naso/orogastric, naso/oroenteric).	Abdomen (gastrostomy, jejunostomy).
Tube Type	NG, OG, ND, NJ tubes.	Percutaneous Endoscopic Gastrostomy (PEG), Percutaneous Endoscopic Jejunostomy (PEJ), Gastrostomy-Jejunostomy (GJ) tubes.
Placement	Usually bedside, sometimes with imaging guidance.	Endoscopic, radiologic, or surgical placement.
Patient Comfort	Potential for nasal/throat irritation, less discrete.	More comfortable and less socially stigmatizing over time.
Main Advantage	Simple, temporary, minimally invasive placement.	More durable, larger tubes, reduced aspiration risk.

Conclusion

Short-term enteral access is a critical medical intervention for temporary nutritional needs when oral intake is compromised but the GI tract functions. It's often a preferred and more physiological option than parenteral nutrition, requiring careful management to avoid complications like aspiration or tube blockages. For longer-term nutritional support needs beyond a few weeks, transitioning to a long-term enteral access device is typically considered for better comfort and safety.

Frequently Asked Questions

The primary purpose is to provide temporary nutritional support to patients who have a working gastrointestinal tract but cannot safely or adequately consume food by mouth.

Short-term enteral access is typically used for less than 30 to 60 days, or about four to six weeks, depending on the patient's condition and recovery progress.

The most common types are nasogastric (NG) tubes, inserted through the nose into the stomach, and nasoenteric tubes, which extend past the stomach into the small intestine.

Correct placement is confirmed through various methods, most definitively with a chest X-ray. Other checks include testing the pH of aspirated fluid and observing the patient for signs of respiratory distress.

Major complications include aspiration (food in the lungs), tube clogging or dislodgement, infection, and gastrointestinal issues like nausea, vomiting, and diarrhea.

Yes, medications can be given through the feeding tube, but they must be in liquid or finely crushed form. The tube should be flushed before and after administration to prevent blockage.

A patient might transition to long-term enteral access (e.g., a PEG tube) if their need for tube feeding extends beyond the initial temporary period of four to six weeks.
