Hospitals in the region are keeping a careful eye on their IV fluid supplies, and are using less of the precious liquid as a way to cope with supply shortages in the wake of Hurricane Helene. The powerful storm damaged a factory in North Carolina that produces more than half the U.S. supply of intravenous fluids, or IV fluids. The factory's shutdown has led to a national shortage of IV fluids, and healthcare workers in Philadelphia and the surrounding region are doing what they can to conserve supplies.
