Area of Science:

  • Clinical Nutrition
  • Medical Nutrition Therapy
  • Evidence-Based Medicine

Background:

  • Specialized nutritional support (SNS) is crucial in managing complex medical conditions.
  • Parenteral and enteral nutrition are key modalities for SNS.
  • Data on SNS application varies across different clinical contexts.

Purpose of the Study:

  • To review and synthesize available data on specialized nutritional support (SNS).
  • To examine the application of parenteral and enteral SNS in specific patient populations.
  • To provide an overview of SNS evidence in critical illness, perioperative care, wasting syndromes, and GI diseases.

Main Methods:

  • Literature review of existing data on specialized nutritional support.
  • Synthesis of evidence pertaining to parenteral and enteral nutrition.
  • Categorization of data by clinical scenario: critical illness, perioperative care, wasting syndromes, and gastrointestinal disease.

Main Results:

  • Data on SNS use is available for common clinical scenarios.
  • Evidence supports SNS in critical illness, perioperative settings, and wasting conditions like cancer and HIV.
  • SNS plays a role in managing gastrointestinal disorders such as short bowel syndrome, IBD, and pancreatitis.

Conclusions:

  • Specialized nutritional support (parenteral and enteral) is applicable across a spectrum of clinical conditions.
  • Evidence synthesis aids in understanding the role and application of SNS.
  • Further research may refine SNS protocols for specific patient groups.
