GI issues in complex patients

Managing GI issues in complex patients

What is a complex patient?
A complex patient is someone who requires specialised artificial nutritional support in terms of dietary composition.  Patients who experience failure of one or more organs make nutritional support challenging, and a common complication of complex patients is the malabsorption of nutrients, which include macro and micronutrients.


Examples of complex patients include those with:
  • Short bowel syndrome, multiple surgery or trauma
  • Chylothorax
  • Acute or chronic Pancreatitis
  • Acute liver failure
  • Respiratory failure requiring mechanical ventilation
  • High output stomas
The aim of meeting these patients’ nutritional requirements includes:
  • Optimising nutrient absorption
  • Providing key substrates to minimise loss of lean body mass
  • Feeding the gut as far as possible to reduces chance of bacterial translocation, degradation of gut-barrier function and maintaining bowel function
  • Optimising Leucine intake to promote muscle anabolism
  • Providing optimal nutrient levels without increasing osmolarity of feeds
  • Reducing the amount of insulin resistance often experienced in this patient group
