U.S. health regulators announced a recall of CareFusion’s Alaris pump module Model 8100, saying a potential keypad malfunction in the infusion pump could cause serious injury or death. The U.S. Food and Drug Administration said the affected pump modules, used for delivering a variety of fluids, drugs and blood products to patients, were manufactured between October 2011 and February 2012. The FDA classified the action as a Class I recall on its website, meaning that the defective units could cause serious harm to a patient’s health.
