Oral Assisted Feeding
Assisted oral feeding is the first and often preferred option when an individual has some ability to swallow but needs help with the process. This method focuses on maximizing the individual's enjoyment of food and the social aspects of mealtimes, while providing the necessary support to ensure safety and adequate intake.
Techniques for Hand Feeding
Careful hand feeding is a cornerstone of oral assisted feeding, especially for those with conditions like dementia. Techniques include:
- Safe Positioning: Ensuring the individual is seated upright at a 90-degree angle with their head slightly tilted forward (the chin-tuck position) reduces the risk of aspiration.
- Appropriate Pace and Bites: Offering small, manageable bites and allowing ample time for chewing and swallowing helps prevent choking. Caregivers should watch for signs that the food has been swallowed before offering the next bite.
- Using Cues: Verbal cues, like describing the food, and non-verbal cues, such as mimicking chewing, can help stimulate the eating process.
Specialized Tools and Techniques
Adaptive equipment can greatly enhance an individual's independence and safety during mealtimes. Examples include:
- Adaptive Utensils: Spoons with shallow bowls, bent handles, or weighted grips can assist those with limited dexterity or tremors.
- Non-Slip Dishes: Bowls and plates with suction bases help prevent spills and provide stability.
- Robotic Feeding Devices: Advanced technology like the Obi robotic feeder can offer significant independence for individuals with limited arm or hand movement, automating the feeding process.
Enteral (Tube) Feeding
Enteral feeding delivers nutrients directly into the stomach or small intestine via a tube. It is used when individuals cannot safely swallow or consume enough calories by mouth. The choice of tube depends on the anticipated duration of feeding and the patient's specific medical condition.
Short-Term Enteral Feeding Tubes
For individuals needing temporary support, tubes are typically inserted through the nose.
- Nasogastric (NG) Tube: This is a thin tube inserted through the nose, down the esophagus, and into the stomach. It is generally used for short-term feeding, usually six to eight weeks. NG tubes are less invasive to place than abdominal tubes but can be more visible and cause discomfort.
- Nasojejunal (NJ) Tube: Similar to an NG tube, but the tube extends further, past the stomach and into the small intestine (jejunum). This is used when stomach feeding is not tolerated or a patient is at high risk for aspiration.
Long-Term Enteral Feeding Tubes
For individuals requiring feeding assistance for more than six to eight weeks, tubes are surgically placed directly into the abdomen.
- Gastrostomy (G) Tube: A tube is inserted directly into the stomach through a small incision in the abdominal wall. A common type is the Percutaneous Endoscopic Gastrostomy (PEG) tube, placed using an endoscope. This is a more permanent and discreet option than nasoenteric tubes.
- Jejunostomy (J) Tube: This tube is inserted through the abdominal wall directly into the small intestine (jejunum). A jejunostomy is used when the stomach is not functioning correctly or to reduce aspiration risk in certain high-risk patients.
Feeding Schedules and Administration
With tube feeding, the administration method can vary:
- Bolus Feeding: Measured amounts of formula are delivered several times a day, often to mimic mealtimes. This is typically done using a syringe.
- Continuous Feeding: Formula is delivered slowly and continuously over a set period, often overnight, using a feeding pump.
- Gravity Feeding: A bag of formula is hung, and gravity moves the liquid into the tube at a controlled rate.
Parenteral Feeding
Parenteral feeding, or intravenous (IV) nutrition, is used when a person's digestive system cannot absorb nutrients. It is a more complex medical procedure, typically reserved for severe cases.
- Total Parenteral Nutrition (TPN): Provides all nutritional needs intravenously.
- Peripheral Parenteral Nutrition (PPN): Provides partial nutrition through a peripheral IV line, generally for shorter periods.
Comparison of Assisted Feeding Methods
| Feature | Oral Assisted Feeding | Enteral (Tube) Feeding | Parenteral (IV) Feeding |
|---|---|---|---|
| Method | Caregiver hand-feeds or uses adaptive utensils. | Liquid nutrition delivered directly to the stomach or small intestine via a tube. | Nutrients delivered intravenously into the bloodstream. |
| Invasiveness | Non-invasive | Invasive (tube insertion) | Highly invasive (IV line) |
| Common Use | Mild to moderate swallowing issues, dementia, physical limitations. | Inability to swallow safely, malnutrition, severe illness, or post-surgery. | Non-functioning digestive system, severe malnutrition, or short-gut syndrome. |
| Risks | Choking, aspiration pneumonia if not properly executed. | Infection at insertion site, tube blockage, dislodgment, aspiration risk. | Infection, blood clots, liver problems. |
| Benefits | Comfort, social interaction, taste enjoyment, high quality of life. | Ensures adequate nutritional intake, bypasses swallowing problems. | Bypasses the digestive system entirely, ensuring complete nutrition. |
| Caregiver Effort | Time-consuming, requires high levels of attention and patience. | Management of equipment, formula preparation, site care. | Complex medical management, often requiring skilled nursing care. |
Choosing the Right Method
The decision for which assisted feeding method to use is highly individual and depends on several factors. A healthcare team, including a doctor, a registered dietitian, and a speech-language pathologist, will perform an assessment to determine the best approach. Considerations include:
- Medical Condition: A person with advanced dementia may be better suited for careful hand feeding, as studies have not shown significant benefits from tube feeding in this group. In contrast, a patient recovering from a stroke with severe dysphagia may require a short-term NG tube.
- Swallowing Ability: A swallow evaluation by a speech-language pathologist is essential to determine the severity of dysphagia and recommend appropriate texture-modified foods or liquids.
- Prognosis: The expected duration of feeding support will influence whether a temporary nasoenteric tube or a long-term abdominal tube is selected.
- Quality of Life: The patient's preferences, if they are able to express them, are crucial. For some, the social interaction of hand feeding is a priority, while others may prefer the efficiency of a tube feed.

Conclusion
Navigating the different types of assisted feeding can be complex, but understanding the options empowers caregivers and patients to make informed decisions. Whether through supportive oral techniques or more medically advanced tube and IV methods, the goal is always to provide safe, effective nutrition while maximizing comfort and dignity. The right approach is a personalized one, determined through a careful assessment and open communication with a healthcare team, prioritizing the individual's health and quality of life.
