Microbial growth in neonatal intravenous fat emulsion administered over 12 versus 24 hours

To determine whether an extended infusion time (24 hours) of intravenous fat emulsion is associated with an increase in microbial growth, versus a shorter infusion time (12 hours).

Samples were collected from intravenous fat emulsions (n=132), from intravenous fat emulsions prepared in the current 24-hour infusion method (n=55), and from intravenous fat emulsions prepared in the twice-daily (12-hour infusion) method (n=55). In addition, samples were collected from pharmacy (n=22) to test for possible contamination.

No growth was observed in either arm of the study.

Current Kern Medical Center policy of preparation and administration of neonatal intensive care unit intravenous fat emulsion is safe and effective in regard to microbial growth.
