Study Notes
Enteral Nutrition
- Nutritional support involves administering through the nose, esophagus, stomach, or intestines.
- Tube feeding is indicated when the GI tract is functional; prefer oral diet methods before using enteral nutrition.
- Common conditions necessitating enteral nutrition include impaired ingestion, inadequate oral intake, and malabsorption.
Parenteral Nutrition
- Administered intravenously; used when GI tract is non-functional.
- Total Parenteral Nutrition (TPN) is hypertonic and delivered through central venous access for long or short-term.
- Peripheral Parenteral Nutrition (PPN) is isotonic and delivered through peripheral veins for short periods.
Enteral Access
- Short-term feeding uses nasogastric or nasoenteric tubes (less than four weeks).
- Long-term feeding employs gastrostomy or jejunostomy tubes.
- Gastric feeding routes are preferred for comfort and easier management.
Advantages of Enteral Nutrition
- Allows for easy and accurate monitoring of nutrient intake.
- More cost-effective compared to parenteral nutrition.
- Readily available nutrition reduces disease-related risks.
Complications of Enteral Feeding
- Access issues such as tube obstruction.
- Administration challenges including aspiration risk.
- Gastrointestinal complications like diarrhea and potential for overhydration.
Aspiration Pneumonia
- A potential risk from enteral feeds, especially in patients with poor gag reflexes or altered consciousness.
- Mitigation strategies include checking gastric residuals and elevating head during feedings.
Feeding Methods
- Intermittent Feedings: Larger volume (300-400 ml) administered several times a day. Mimics regular eating patterns but may increase aspiration risk.
- Continuous Feedings: Delivered steadily over 8-24 hours, requiring an infusion pump, recommended for critically ill patients to minimize risks.
Gastric Residual Measurement
- Regular measurement of residuals ensures proper gastric emptying and is performed before intermittent feedings or every four hours during continuous feedings.
Indications for TPN
- Indicated for patients NPO for over five days or those with conditions like short bowel syndrome or severe malnutrition.
Complications of TPN
- Risks include infection, fluid/electrolyte imbalances, and metabolic changes like hyperglycemia or hypoglycemia.
Clear Liquid Diet
- Comprises easily digestible fluids like water, broth, and gelatin, typically prescribed for preoperative preparation or digestive issues.
Soft Diet
- Consists of soft foods that are easy to chew and swallow; recommended post-surgery for patients with head, neck, or stomach operations.
Enteral Nutrition
- Nutritional support via placement through the nose, esophagus, stomach, or intestines (duodenum or jejunum).
- Tube feedings require a functioning gastrointestinal (GI) tract; exhaust all oral diet methods before considering enteral nutrition.
Indications for Enteral Nutrition
- Impaired ingestion and inability to consume adequate nutrition orally.
- Impaired digestion, absorption, metabolism, and severe wasting or depressed growth.
Parenteral Nutrition
- Used when gastrointestinal incompetency or hypermetabolic state with poor GI intake occurs.
- Total Parenteral Nutrition (TPN) administered through central venous access, suitable for long- and short-term use.
- Peripheral Parenteral Nutrition (PPN) provided through a peripheral vein, typically for short-term use, featuring less concentrated solutions.
Duration of Tube Feeding
- Nasogastric or nasoenteric tubes are recommended for short-term feeding (less than four weeks).
- Gastrostomy and jejunostomy tubes are used for long-term feeding.
Advantages of Enteral Nutrition
- Allows for easy and accurate monitoring of intake.
- Less expensive than parenteral nutrition and widely available supplies.
- Reduces risks associated with the disease state.
Complications of Enteral Feeding
- Possible access problems (e.g., tube obstruction).
- Administration issues, such as aspiration.
- Gastrointestinal complications like diarrhea and metabolic issues, including overhydration.
Aspiration Pneumonia
- Can occur from enteral feeds, especially in high-risk patients (e.g., poor gag reflex, depressed mental status).
- Strategies to reduce risk include checking gastric residuals and elevating the head of the bed during feeding.
Formula Delivery Methods
- Intermittent feedings involve delivering large amounts (300-400 ml) several times a day, may lead to aspiration higher risk.
- Continuous feedings provide smaller volumes consistently over 8 to 24 hours, suited for critically ill patients.
Checking Gastric Residuals
- Regular measurement of gastric residual volume ensures proper stomach emptying, performed via gentle suction before intermittent feeding and every 4 hours during continuous feeding.
Complications of Parenteral Nutrition
- Includes risks of infection, fluid and electrolyte imbalances, phlebitis, pneumothorax, thromboembolism, and metabolic changes such as hyperglycemia or hypoglycemia.
Clear Liquid Diet
- Comprises clear liquids that are easily digestible and leave no undigested residue.
- Commonly prescribed before medical procedures or for certain digestive issues.
Soft Diet
- Includes soft, easy-to-chew foods; may be required post-surgery such as for head, neck, or stomach operations.
Key Points for Review
- Enteral nutrition is preferred when the GI tract is functional; parenteral nutrition is a backup for severe cases.
- Regular monitoring and management strategies are crucial for both enteral and parenteral nutrition to minimize complications.
- Understanding the dietary needs based on the patient's medical condition is critical for effective nutritional support.
