Hospitals across the U.S. are taking steps to conserve their supplies of IV fluids after Hurricane Helene struck a critical manufacturing plant belonging to the country’s biggest supplier.

Baxter International, a medical technology company responsible for making IV fluids for most U.S. hospitals, said Sunday that it would temporarily close production at its North Cove, North Carolina-based facility because of flooding from Helene, raising concerns about a potential nationwide shortage.

IV fluids are used to deliver drugs or water with electrolytes directly into a patient’s bloodstream. They’re also critical for surgery, when a person is unable to eat or drink, to keep them hydrated. Baxter also makes specialty fluids, such as peritoneal dialysis fluid, which helps patients with kidney failure filter waste from their blood, as well as irrigation fluids, used during procedures to clean or flush wounds.
