INQUIRER: City emergency medical officials brought extra ambulances to the finish line, where they expected a gathering of more than 40,000 athletes and spectators. By 10:15 a.m., a steady stream of racers-turned-patients had walked or were wheeled into the medical tent. “Our enemy just came out,” Jeremiah Laster, the Philadelphia Fire Department’s medical-services field operation chief, said, referring to the sun. The number-one medical issue for runners, he said, was dehydration. In all, 179 people were seen for injuries ranging from sprains and cramps to heat-related illnesses. Thirty-six, including racers who needed assistance along the route, were transported to hospitals – more than last year, Laster said. An unidentified male runner suffered cardiac trouble and was taken to the Hospital of the University of Pennsylvania, where he was listed in stable condition, Laster said. “When you look at 30,000 runners,” he said, “that’s not that bad.” MORE
