Dawn Arrigoni, 35, went to the emergency room at Woodwinds Hospital complaining of vomiting, fever and abdominal pain. The nurses there attempted to place a peripheral IV but had trouble placing it.
A nurse practitioner then placed an intraosseous (IO) line. An intraosseous infusion line is used in the process of injecting directly into the marrow of the bone to provide a non-collapsible entry point into the systemic venous system of a patient. This method is often used to provide fluids and medication when an IV is not practicable as in this case. The IO line is considered an efficient method to provide intravenous fluids or medication.
Shortly after the IO line was put in place, Arrigoni complained of significant pain for which she was given the pain reliever Dilaudid. Over an hour and a half later, a nurse noted swelling in her lower left leg, which appeared to be pale in color. She continued to complain to the hospital staff of leg pain.
