Baxter International has issued a recall of its HomeChoice dialysis machines after the device firm received reports of patients overfilling their abdominal cavities. FDA has classified the recall as Class I. The company says it is still trying to find the source of the problem, but Baxter also says that the devices don't need to be physically returned and that they are still usable. Device users should be on the lookout for signs of abdominal overflow, which can include vomiting, difficulty breathing, or spitting up.
