Jejunostomy Tube (J-Tube) Feeding.
Introduction
Jejunostomy tube (J-tube) feeding is a method of long-term enteral nutrition for patients who cannot tolerate oral, nasogastric (NG), or gastrostomy (G-tube) feeding. The J-tube is inserted directly into the jejunum (the second part of the small intestine) through the abdominal wall.
This method is commonly used for patients with severe gastric dysfunction, high aspiration risk, or gastrointestinal obstructions. Nurses play a crucial role in monitoring the tube, administering feeds, preventing complications, and educating caregivers.
1. Principles of Jejunostomy Tube Feeding
Ensure Safe Tube Placement – Confirm that the tube is correctly positioned in the jejunum.
Provide Adequate Nutrition – Deliver appropriate calorie and fluid intake for the patient’s needs.
Prevent Aspiration and Reflux – Since the tube bypasses the stomach, aspiration risk is reduced.
High Aspiration Risk (Stroke, Neuromuscular Disorders, Coma)
Bypasses the stomach, reducing aspiration
Severe GERD or Reflux
Reduces risk of regurgitation
Esophageal or Gastric Cancer
Prevents obstruction of feeding
Intestinal Malabsorption or Short Bowel Syndrome
Ensures controlled nutrient absorption
Prolonged Post-Surgical Recovery
For patients recovering from GI surgeries
6. Contraindications for J-Tube Feeding
Jejunostomy tube placement is not suitable in certain conditions.
Contraindication
Reason
Severe Bowel Obstruction
Prevents movement of enteral feeds

Total Parenteral Nutrition (TPN).
Introduction
Total Parenteral Nutrition (TPN) is a method of providing complete nutrition intravenously for patients who cannot tolerate enteral feeding due to gastrointestinal dysfunction. TPN supplies essential nutrients, including carbohydrates, proteins, fats, vitamins, minerals, and electrolytes, through a central venous catheter (CVC).
Nurses play a crucial role in administering TPN, monitoring complications, preventing infections, and educating patients and caregivers.
1. Principles of Total Parenteral Nutrition (TPN)
Provide Complete Nutrition – TPN supplies all essential nutrients directly into the bloodstream.
