Q: Which very commonly use resuscitation fluid in ICU may cause pesudo-hyperamylasemia?


Answer:
Hetastarch

The infusion of hydroxyethyl-starch leads to hyperamylasemia due to the complex structural interrelation of the amylase molecules in the serum and the hydroxyethyl-starch molecules. The amylase clearance is reduced because glomerular filtration of the macromolecules thus formed is not possible. It takes about a week for a level to return to normal after hetastarch infusion.

Workup for presumed pancreatitis may be expensive and futile.
