Three people were killed in the Boston Marathon bombings and 120 were wounded; 50 people remain hospitalized. Michael Collins, M.D., speaks with "Sound Medicine" about recent developments in trauma surgery that helped in Boston. From the horrific injuries caused by improvised explosive devices in the Afghanistan and Iraq wars, trauma surgeons learned how to better treat lower-extremity wounds like the ones seen in Boston. According to Dr. Collins, having first responders at the scene allowed for faster transportation to medical facilities, which helped save more limbs and lives. He notes that disaster training helps surgeons overcome the shock of injuries caused by tragedies.
