- •Flexible endoscopes had residual fluid after reprocessing and drying.
- •Fluid resembled simethicone used to reduce foam and bubbles.
- •Photographs and laboratory analysis found that the fluid contained simethicone.
- •Residual fluid containing simethicone may impact reprocessing effectiveness.
