A makeshift memorial pays tribute to the victims of the Boston Marathon bombings. But what about the medical teams, the doctors, and the EMTs? How are they coping in the aftermath? And what if they were missing their own relatives while they were saving the lives of those injured?
Emergency physician Dr. Leana Wen's husband had attended and watched the marathon from near the finish line. As patients streamed into Massachusetts General Hospital that Monday, Wen worried one of them would be her husband.
"While I was treating patients, I had no idea whether the next patient was going to be my husband," Wen told CNN's Jake Tapper. "Because there was soot and blood everywhere, I thought there was a good chance that the next patient I would be seeing on the stretcher would be my husband."
Wen first shared her story on NPR. She said in the end, thankfully, her husband was unharmed.
For her, the attack has taken an emotional toll.
"It was a horrific day," said Wen, who estimates nearly three dozen patients flooded into the hospital in two hours.
"Technically and medically, we were ready. We had done drills, we knew what to do with each individual patient who came in," said Wen. "But I had never seen trauma like this before. The volume and the nature of the trauma was really chilling, really shocking."
"I have nightmares, and whenever I hear sirens, or the loud speaker, or the ambulance going off, I think about Monday," said Wen.
Wen said she knows she has to get better.
"I need to take care of myself, and our colleagues, in order for us to take care of our patients going forward," said Wen.
