Some institutions will not infuse a fat emulsion, such as Intralipid, into central venous access devices (CVAD) because:
1
Lipid residue may accumulate in the CVAD and occlude the catheter.
2
If the catheter clogs, there is no treatment other than removal and replacement.
3
Lipids are necessary only in the most extreme cases to prevent essential fatty acid (EFA) deficiency
4
Fat emulsions are very caustic.
