The Weekend Wall Street Journal features Brigham and Women’s Hospital doctor Emily Loving Aaronson’s first-hand account of the harrowing medical response to Monday’s Boston Marathon bombings:

On the Front-Lines of Battlefield Triage in Boston

Hospital emergency rooms in the Boston area were on high alert again in the early-morning hours on Friday. Locked down, with no one allowed in or out. It has been a long, tense week here, one marked by sorrow and anger, resilience and heroism. I witnessed all of that and more Monday at in the Brigham and Women’s Hospital emergency room, where 31 of the victims of the bombing at the marathon were taken . . .

They started rolling in. Bloodied, confused, crying and in shock. We cleared the department as quickly as we could—moving the least injured patients into our observation area and trying to make room for the sickest patients to be seen as quickly as possible. One of our senior residents gravitated toward the “triage” roll, taking responsibility for meeting each stretcher at the door and sorting patients based on the seriousness of their condition.

Which was a microcosm of the seriousness of Boston’s condition.

There were two million stories in the naked City on the Hill that night.

Aaronson’s is just one of them. But a compelling one.
