The U.S. Food and Drug Administration said on Wednesday that many people have been sickened and one has died after receiving intravenous fluids that were meant to be used for training purposes only. News of the death comes less than a month after the FDA told physicians not to use simulated intravenous products made by Wallcur LLC, a private company based in San Diego, California that makes products for medical training. The FDA said at the time that there had been reports of serious adverse events associated with use of some of Wallcur's products.
