Feeding intolerance is one of the most significant contributors to growth failure in VLBW preterm infants. The inability to sustain enteral feedings also contributes to extended periods of parenteral nutrition, which often requires central venous access, thereby increasing the risk of infection.
What is feeding intolerance?
• What is feeding intolerance? When you first start a tube feeding, it may take a few days for your body to adjust to the formula and feeding routine. But there are times, when you simply may not tolerate the feeding formula you have been asked to use – you may feel unwell and cannot take all of your formula each day.

What does feeding intolerance mean?
Feeding intolerance (FI), defined as the inability to digest enteral feedings associated to increased gastric residuals, abdominal distension and/or emesis, is frequently encountered in the very preterm infant and often leads to a disruption of the feeding plan.
What causes feeding intolerance?
Food intolerances arise if the body is unable to digest a certain food. This impairment may be due to a lack of digestive enzymes or a sensitivity to certain chemicals. Foods commonly associated with food intolerance include: milk.
What is the meaning of enteral feeding?
Enteral nutrition, also known as tube feeding, is a way of delivering nutrition directly to your stomach or small intestine. Your doctor might recommend tube feeding if you can't eat enough to get the nutrients you need. When tube feeding occurs outside the hospital, doctors refer to it as home enteral nutrition (HEN).

What is enteral feeding intolerance?
Enteral feeding intolerance (EFI) is a common feature in critically ill patients worldwide. However, there is no clear, widely agreed-upon definition available, with various studies rarely using the same definition. The term EFI is frequently used to describe vomiting or large gastric residual volumes associated with enteral feeding as a result of gastroparesis/delayed gastric emptying. However, the syndrome of EFI may represent the consequence of various pathophysiological mechanisms, and this heterogeneity may explain varying associations with outcomes. In clinical practice, a pragmatic definition may be useful. A pragmatic definition of EFI is that a clinician has decided to reduce the amount of enteral nutrition specifically because features of gastrointestinal dysfunction appeared during enteral feeding. For research purposes, a more detailed definition of EFI is required to improve knowledge and explore interventions that may improve patient-centered outcomes. The objective of this review is to summarize available evidence on existing definitions, pathophysiological mechanisms, and the clinical relevance of EFI in critically ill patients. Based on current knowledge, we propose a conceptual framework for a definition of EFI for a future consensus process.
What is EFI in clinical practice?
A pragmatic definition of EFI is that a clinician has decided to reduce the amount of enteral nutrition specifically because features of gastrointestinal dysfunction appeared during enteral feeding.
What is enteral feeding?
Enteral feeding refers to intake of food via the gastrointestinal (GI) tract. The GI tract is composed of the mouth, esophagus, stomach, and intestines. Enteral feeding may mean nutrition taken through the mouth or through a tube that goes directly to the stomach or small intestine. In the medical setting, the term enteral feeding is most often ...
What are the complications of enteral feeding?
There are some complications that can occur as a result of enteral feeding. Some of the most common include: aspiration, which is food going into the lungs. refeeding syndrome, dangerous electrolyte imbalances that may occur in people who are very malnourished and start receiving enteral feeds.
Why do people need enteral feeds?
A person on enteral feeds usually has a condition or injury that prevents eating a regular diet by mouth, but their GI tract is still able to function. Being fed through a tube allows them to receive nutrition and keep their GI tract working. Enteral feeding may make up their entire caloric intake or may be used as a supplement.
Why can't I eat?
If you can’t eat enough, you’re at risk for malnourishment, weight loss, and very serious health issues. This may happen for a variety of reasons. Some of the more common underlying reasons for enteral feeding include: 1 a stroke, which may impair ability to swallow 2 cancer, which may cause fatigue, nausea, and vomiting that make it difficult to eat 3 critical illness or injury, which reduces energy or ability to eat 4 failure to thrive or inability to eat in young children or infants 5 serious illness, which places the body in a state of stress, making it difficult to take in enough nutrients 6 neurological or movement disorders that increase caloric requirements while making it more difficult to eat 7 GI dysfunction or disease, although this may require intravenous (IV) nutrition instead
Why is enteral feeding important?
There are some situations where enteral feeding is used as a long-term solution, such as for people with movement disorders or children with physical disabilities. In some cases, enteral nutrition can be used to prolong life in someone who is critically ill or an older person who can’t maintain their nutritional needs.

What are the drawbacks of not having a feeding protocol in the ICU?
She explains that gastric residuals may be checked by nursing staff, but if doing so is not mandated by a formal protocol or policy, the practice is likely to be inconsistent and unreliable. “Some nurses may hold tube feeding for a GRV that is double the ordered infusion rate. For example, if the feeding is running at 40 mL/hour, then the nurse may hold the feed for an 80 mL GRV. Another may routinely hold tube feeding for GRV greater than 200 mL. If a physician doesn’t actively write an order to hold tube feeding, then it may be held indefinitely until someone decides to restart. In this case, it takes a fairly proactive nurse to go to the physician to obtain an order to resume feeding. That’s where not having a protocol really handicaps the ICU in terms of feeding patients adequately.”
What are the contributing factors to GI tract disease?
Contributing factors may include impaired function of the enteric nerve and smooth muscles of the GI tract, inflammation, surgery, medications such as opioids, electrolyte imbalances, hyperglycemia, sepsis, increased cranial pressure, and the presence of disease itself.1.
Is jejunal feeding safe in ICU?
Welpe and colleagues sought to assess the safety, success, and time efficiency of establishing jejunal feeding in ICU patients via a fluoroscopy-guided technique, as discussed in the March 2010 issue of the Journal of Parenteral and Enteral Nutrition. Based on the results of their study, the authors concluded fluoroscopy-guided placement of jejunal feeding tubes by adequately trained ICU staff to be a fast and safe procedure, one that facilitates the initiation of EN in the critically ill population in the face of gastroduodenal dysfunction.
Is enteral feeding safe?
When compared with parenteral nutrition administration, enteral feeding is considered safer and is correlated with better patient outcomes, prevents atrophy of the intestinal villi, and maintains the normal gut mucosal barrier, thereby discouraging bacterial translocation. The initiation of early EN within 24 hours of ICU admission is recommended and believed to reduce infectious complications.1 Dietitians may find themselves plagued and frustrated by the host of barriers that make the provision of adequate and timely enteral feeding difficult to achieve.
Does naloxone help with intestinal motility?
Also per ASPEN guidelines, the use of naloxone (an opiate antagonist) infused through a feeding tube to counteract effects of opioid narcotics on the gut and thus improve intestinal motility was shown in one level 2 study to significantly increase the volume of EN infused, reduce gastric residual volumes (GRVs), and decrease the incidence of ventilator-associated pneumonia.2
Does GRV cause underfeeding?
According to the researchers, the results indicate that monitoring GRV may hinder EN delivery, leading to underfeeding, by causing unnecessary interruptions. They conclude that the practice of holding EN delivery when GRV reaches an arbitrarily determined cutoff level is not justified by scientific evidence, increases nurse workload, and doesn’t decrease the risk of ventilator-assisted pneumonia. The results suggest that the cessation of GRV monitoring in mechanically ventilated ICU patients may be discontinued; however, more studies are warranted to substantiate these findings.4
Why is enteral feeding important?
It is essential to start enteral nutrition early to preterm infants by giving small amounts of milk (preferably human milk) to ensure that metabolic homeostasis is kept stable and to limit postnatal growth retardation. Increasing feeding volumes to reach "full enteral feeding" is limited by individual feeding tolerance.
