- Consider parenteral nutrition (PN) when nutritional requirements
cannot be met through use of gastrointestinal (GI) tract (Table 1).
- Consider after suboptimal nutritional intake for:
- 1 day in preterm
infants
- 2–3 days in term infants
- 3–5 days in critically injured children
- 5–7 days in other children
- 7–14 days in older children and adults
- Route and type of PN depend on patient’s clinical
state and expected length of PN therapy (Figure 1).
