(Newser) – A Florida woman was airlifted to a burn center after her face erupted in flames during surgery. The 29-year-old mom of three was having cysts removed from her head when the accident occurred. Firefighters were called, but the flash fire was out by the time they arrived. It's not clear what caused the blaze, but electricity, heat, and lasers may spark flames in an operating room that are then fed by oxygen and surgical materials. The woman was being treated for burns to her face and neck, and was in stable condition. “I am in shock," her mom told the Crestview News Bulletin. "This is not what happens with a routine outpatient surgery." She said her daughter told her: "They woke me up and everyone around me was hysterical." (Read more fire stories.)
