WINSTON-SALEM - Another N.C. hospital said Wednesday it received barrels that were supposed to contain a cleanser for surgical instruments but instead contained hydraulic fluid.
A spokesman for Wake Forest Baptist Medical Center said workers at the Winston-Salem hospital caught the mistake immediately, so no patients underwent surgery with instruments washed in hydraulic fluid.
The staff at two hospitals owned by Duke University Health System also complained at some point last year that surgical tools felt slick.
But it wasn't until January that nearly 4,000 patients at Duke Health Raleigh Hospital in Raleigh and Durham Regional Hospital learned their surgeons had unknowingly used instruments washed in hydraulic fluid.
