A feeding tube is a medical device used to provide nutrition to patients who cannot obtain nutrition by mouth, are unable to swallow safely, or need nutritional supplementation. The state of being fed by a feeding tube is called gavage, enteral feeding or tube feeding. Placement may be temporary for the treatment of acute conditions or lifelong in the case of chronic disabilities. A variety of feeding tubes are used in medical practice. They are usually made of polyurethane or silicone. The diameter of a feeding tube is measured in French units (each French unit equals 0.33 millimeters). They are classified by site of insertion and intended use.
There are dozens of conditions that may require tube feeding. The more common conditions that necessitate feeding tubes include prematurity, failure to thrive (or malnutrition), neurologic and neuromuscular disorders, inability to swallow, anatomical and post-surgical malformations of the mouth and esophagus, cancer, Sanfilippo syndrome, and digestive disorders.
The effectiveness of feeding tubes varies greatly depending on what condition they are used to treat.
Feeding tubes are used widely in children with excellent success for a wide variety of conditions. Some children use them temporarily until they are able to eat on their own, while other children require them longterm. Some children only use feeding tubes to supplement their oral diet, while others rely on them exclusively.
Patients with advanced dementia who are unable to feed themselves should have another person feed them in preference to the medical intervention of having a feeding tube. In such patients, feeding tubes do not increase life expectancy or protect the patient from aspiration pneumonia. Feeding tubes can also increase the risk of pressure ulcers, require pharmological or physical restraints, and lead to patient distress. There is evidence which shows that patients who get feeding assistance rather than tubes have better outcomes. In the final stages of dementia, assisted feeding may still be preferred over a feeding tube to bring benefits of palliative care and human interaction even when nutritional goals are not being met.
