Nutrition for Infant with Short Bowel Syndrome


Nutrition for the infant with short bowel syndrome and intestinal failure is a very significant issue to know about.

Nutrition is a critical aspect of care for infants with Short Bowel Syndrome (SBS) and Intestinal Failure (IF) because these conditions can significantly impair the infant’s ability to absorb essential nutrients and fluids from their gastrointestinal tract. Managing nutrition for these infants requires a multidisciplinary approach involving pediatric gastroenterologists, dietitians, nurses, and other healthcare providers. Here’s an overview of the key considerations for nutrition in infants with SBS and IF:

  1. Diagnosis and Assessment:
    • Diagnosis: SBS is a condition where a significant portion of the small intestine is missing or non-functional due to surgical removal or congenital abnormalities. IF refers to the inability of the intestines to digest and absorb nutrients and fluids adequately.
    • Nutritional Assessment: Accurate assessment of the infant’s nutritional status, growth, and development is essential. This typically includes monitoring weight, length, head circumference, and laboratory values such as blood electrolytes and nutrient levels.
  2. Total Parenteral Nutrition (TPN):
    • TPN is often a primary source of nutrition for infants with SBS and IF, especially in the acute phase after diagnosis or surgery.
    • TPN provides essential nutrients and fluids intravenously, bypassing the damaged or insufficient intestinal tract.
    • The composition of TPN is individualized based on the infant’s specific nutritional needs, which can change over time as the infant grows and adapts.
  3. Enteral Nutrition:
    • Gradual introduction of enteral feeds (feeding through the gastrointestinal tract) is a key goal in managing these infants.
    • Enteral feeds can stimulate intestinal adaptation and reduce dependence on TPN.
    • Various enteral feeding methods may be used, including oral feeds, nasogastric tube feeding, or gastrostomy tube placement, depending on the infant’s condition and capabilities.
  4. Monitoring and Adjusting Nutrition:
    • Regular monitoring of the infant’s nutritional status and growth is crucial to make necessary adjustments in the nutritional plan.
    • Dietitians play a vital role in calculating nutrient requirements and modifying TPN and enteral feeds accordingly.
    • Laboratory tests and imaging studies can help assess intestinal adaptation progress and guide nutritional changes.
  5. Specialized Nutrient Formulas:
    • Infants with SBS and IF may require specialized enteral formulae that are easier to digest, contain specific nutrients, and are designed for infants with gastrointestinal issues.
    • Formulas may be adapted to provide the appropriate macronutrient ratios, micronutrients, and electrolytes.
  6. Intestinal Rehabilitation:
    • Some infants may undergo surgical procedures or interventions to promote intestinal adaptation, such as bowel lengthening procedures or bowel tapering.
    • The success of these interventions can influence the infant’s ability to tolerate enteral feeds and reduce reliance on TPN.
  7. Managing Complications:
    • Infants with SBS and IF are at risk of complications like electrolyte imbalances, infections, and liver disease due to long-term TPN use.
    • Close monitoring and prompt management of these complications are essential to ensure the infant’s well-being.

In conclusion, nutrition for infants with Short Bowel Syndrome and Intestinal Failure is a complex and dynamic process that requires close collaboration between healthcare professionals and caregivers. Individualized care plans, regular monitoring, and a focus on promoting intestinal adaptation are key strategies to optimize the nutritional management of these vulnerable infants. Early intervention and ongoing support can significantly improve their long-term outcomes and quality of life.

Goals of Nutrition Therapy

The goals of nutrition therapy for intestinal rehabilitation in infants with Short Bowel Syndrome (SBS) and Intestinal Failure (IF) are focused on improving the infant’s ability to digest and absorb nutrients from their gastrointestinal tract and reducing their dependence on parenteral nutrition (TPN). These goals aim to promote optimal growth, development, and overall health. Here are the three primary goals of nutrition therapy for SBS/IF:

  1. Promoting Intestinal Adaptation:
    • One of the primary objectives is to stimulate the remaining bowel to adapt and increase its absorptive capacity.
    • This adaptation may involve the lengthening and thickening of the remaining intestines and the development of new absorptive surface area.
    • Nutrition therapy should aim to provide the necessary nutrients and growth factors to support this process.
  2. Reducing Dependency on Parenteral Nutrition (TPN):
    • TPN is a lifesaving therapy for infants with SBS/IF, but the goal is to minimize its use as much as possible.
    • Nutrition therapy should focus on transitioning the infant to enteral nutrition (feeding through the gastrointestinal tract) gradually.
    • As the intestines adapt, the amount of TPN required should decrease, and the infant’s reliance on enteral feeds should increase.
  3. Achieving Optimal Growth and Development:
    • Nutrition therapy aims to support appropriate weight gain, linear growth, and overall development in the infant.
    • Adequate nutrition is essential for brain development, bone health, and the development of other vital organs.
    • Careful monitoring of growth parameters and nutrient intake is necessary to ensure that the infant is thriving.

To achieve these goals, healthcare providers, including pediatric gastroenterologists and dietitians, work closely with the infant’s caregivers to design and adjust a personalized nutrition plan. This plan takes into account the specific needs and clinical progress of the infant, with the ultimate aim of improving intestinal function, minimizing complications, and providing the best possible quality of life for the child with SBS/IF.

Nutrient of Concern

Infants who are dependent on parenteral nutrition (PN) are at risk of nutrient imbalances or deficiencies due to the unique challenges of this method of feeding. Three nutrients of concern in infants receiving PN are:

  1. Trace Minerals:
    • Zinc, copper, selenium, and other trace minerals are essential for various physiological processes, including growth, immune function, and enzyme activity.
    • Infants on long-term PN are at risk of developing trace mineral deficiencies, which can lead to issues such as impaired growth, delayed wound healing, and compromised immune function.
    • Monitoring of trace mineral levels in the blood and appropriate supplementation is essential to prevent deficiencies.
  2. Fat-Soluble Vitamins:
    • Fat-soluble vitamins (A, D, E, and K) are absorbed in the small intestine, which may be bypassed or compromised in infants on PN.
    • Deficiencies in fat-soluble vitamins can lead to various health problems, such as vitamin D deficiency resulting in bone disorders and vitamin K deficiency leading to bleeding disorders.
    • Supplementation of fat-soluble vitamins is often necessary in PN-dependent infants to ensure they receive adequate amounts of these essential nutrients.
  3. Electrolytes  Electrolyte imbalances, particularly in sodium, potassium, calcium, and phosphorus, can occur in infants on PN. PN solutions typically contain electrolytes, but the balance may need to be carefully adjusted based on the infant’s specific needs and clinical condition.Monitoring electrolyte levels and maintaining a proper balance is crucial to prevent conditions like hypernatremia, hypokalemia, or hypocalcemia.

It’s important to note that PN for infants is highly individualized, and the nutrient composition of the PN solution should be tailored to the infant’s specific medical condition, growth requirements, and nutrient deficiencies or excesses. Regular monitoring of nutrient levels in the blood and close collaboration between healthcare providers, including dietitians and pediatric gastroenterologists, is essential to ensure that the infant on PN receives the right balance of nutrients and avoids nutrient-related complications.

Benefits of Maternal Human Milk

Maternal human milk provides several benefits to infants with Short Bowel Syndrome (SBS) or Intestinal Failure (IF), despite the challenges these infants may face in terms of their ability to absorb nutrients and fluids. Here are three significant benefits:

  1. Immunological Protection:
    • Maternal breast milk contains numerous immunological components, including antibodies (IgA and IgG), white blood cells, and immune-boosting factors, which help protect the infant from infections and illnesses.
    • Infants with SBS/IF may be more susceptible to infections due to their compromised gastrointestinal function, and breast milk provides a vital defense against these risks.
  2. Gastrointestinal Tolerance:
    • Human milk is easily digested and well-tolerated by the infant’s gastrointestinal tract.
    • Breast milk is less likely to cause feeding intolerance or complications such as diarrhea or allergic reactions compared to some commercial infant formulas, making it particularly valuable for infants with compromised gut function.
  3. Promoting Intestinal Adaptation:
    • Breast milk contains growth factors and bioactive molecules that support intestinal development and adaptation.
    • These factors can help stimulate the infant’s remaining intestines to grow, lengthen, and increase their absorptive capacity, which is especially important for infants with SBS/IF.

In addition to these benefits, maternal breast milk provides optimal nutrition for infants with SBS/IF, with a balance of proteins, fats, carbohydrates, vitamins, and minerals that can support growth and development. However, it’s crucial to work closely with healthcare professionals, including lactation consultants and dietitians, to ensure that the breast milk is appropriately fortified and supplemented to meet the specific nutritional needs of the infant, especially if they are dependent on parenteral nutrition (PN) as well.
