Standard
trace
element mixtures are available, but requirements should be monitored
and adjusted based on serum concentrations.
Iron
can be given intramuscularly as needed. When transferrin
levels are low, free iron increases and can increase susceptibility
to infections. In addition, critically ill or malnourished patients
often have no bone marrow response to iron.
Copper
supplementation must be administered with caution to avoid toxicity.
Extra zinc may be needed by some patients to promote wound healing.
