LAS VEGAS -- Their concert turned into a siege, and now their lives may become a battle.
The staggering count of people injured in the shooting at a Las Vegas music festival means their recoveries are likely to be as varied as the victims themselves. Some injuries are as simple as broken bones, others gunshot wounds involving multiple surgeries and potential transplants, and all come with the added emotional scars of enduring the deadliest shooting in modern U.S. history, with 59 killed.
At least 130 people remained hospitalized Tuesday, with 45 listed in critical condition. Hospitals said 185 others had already been released. At Sunrise Hospital and Medical Center alone, the count of those treated included 120 people who were struck by gunfire, a glimpse of the amount of ammunition unleashed in the attack.
Rehabilitation for the most seriously hurt victims will take far longer than many may realize.
"Years," said Dr. Thomas Scalea, physician-in-chief at the University of Maryland's Shock Trauma Center in Baltimore, one of the nation's largest trauma centers. "It's not days or weeks."
Edward Leon raced to Las Vegas from Palm Springs, California, after learning his niece was shot in the stomach. He said he cried the whole way there. Although she survived an initial operation, he worries about what will come next.
"She's out of surgery," he said, "but it's a long road ahead."
At the site of the attack, people fashioned stretchers out of fence posts and tarps, and tourniquets from belts. At area hospitals, the scene was similarly grave.
"It was like a war zone," said Dr. Jay Coates, a trauma surgeon at University Medical Center of Southern Nevada, who operated on three people with gunshot wounds.
Coates saw news of the shooting flash across his phone Sunday night and rushed to the hospital. Ambulances were parked four and five deep. Dozens of wounded filled the trauma bay inside. There were people with injuries to their lungs, liver and spleens, some with huge wounds torn open by bullets. Eight or nine surgeons made flash assessments.
"Who's the most injured?" Coates said they would ask themselves. "Who's dying the fastest?"
He treated similar wounds while on big-city hospital duty in Detroit and Philadelphia, but never so many at once. After the Vegas shooting, eight operating rooms were running simultaneously. It was hours of frantic response before doctors had a moment to catch their breaths.
"At this point, I'm still processing. I have no idea who I operated on," Coates said. "They were coming in so fast. ... We were just trying to keep people from dying."
Benjamin Kole, a 50-year-old firefighter who attended the concert, said revelers were packed in tightly, making their upper torsos and heads the most easily targeted by the gunman, Stephen Paddock, who fired from a 32nd-floor suite at the Mandalay Bay hotel across from the concert grounds. The bullet wounds he saw were largely concentrated on people's upper bodies.
Their prognoses depend heavily on where exactly the bullets struck.
"It really is a game of millimeters and centimeters," said Dr. Jack Sava, trauma director at MedStar Washington Hospital Center in Washington, D.C.
Bullets can pass through a victim's body and miss vital organs, or veer slightly and leave a person paralyzed or dead. Sava cared for House Majority Whip Steve Scalise, a Republican who was shot during a congressional baseball practice over the summer, and said patients and their families have to deal with the uncertainty of their recoveries.
"There's so many things that happen, so many branches in the road," he said. "A lot of times in trauma we talk about death, and that's a tiny tip of the suffering that's caused by injury and gunshot wounds. For every person we talk about living or dying, there's an ocean of suffering we're not talking about."
Rob McIntosh, a 52-year-old from North Pole, Alaska, is among those facing that recovery, having been hit by three bullets at the concert, according to his friend, Mike Vansickle. He said McIntosh had emerged from surgery and would survive.
"He'll get through all this and come out with some stories to tell," Vansickle said.
Others who have been through such trials sounded similar notes of optimism, including Jeff Bauman, who lost his legs in the 2013 Boston Marathon bombing. In a Facebook post, Bauman said those waking up in hospitals may wonder how life could ever be the same again, but they will find a way through the tough moments to go on.
"You will walk again. You will laugh again. You will dance again," he wrote. "You will live again."
