- Key recommendations include:
- Reserve supplies for neonatal patients <1 kg or neonatal patient who are >1 kg after surgery or with sepsis.
- Avoid use of L-cysteine if patient is receiving at least 3 gram/kg per day of protein.
- Consider oral or enteral routes for supplementation if possible.
- Avoid using L-cysteine for catheter patency.
- Compound in central location and add L-cysteine as a separate product from amino acid solutions to help conserve supplies.
- Purchase only the supply needed, do not stockpile.
