3M, the manufacturer of Bair Hugger warming blankets, has faced multiple legal challenges in the ongoing lawsuit regarding its device. Recently, the company attempted to prevent expert witnesses from testifying on behalf of the plaintiffs, but this effort was unsuccessful. The judge overseeing the Bair Hugger multidistrict litigation (MDL), the Honorable Joan N. Ericksen, ruled that expert testimony could be presented to the jury. These expert insights focus on the potential link between the Bair Hugger warming system and post-surgical infections, which could strengthen the claims of numerous plaintiffs.
