The Clark County Medical Society held a ‘Stop the Bleed’ training Monday in recognition of One October.

About 10:15 p.m. Oct. 1, trauma surgeon Dr. Deborah A. Kuhls and her team at University Medical Center in Las Vegas got a call that there had been a shooter on the Strip. They were to prepare for injured patients.

Tougher gun laws, improved mental health care services, clear backpacks, metal detectors and armed school staff. These preventative measures are just a few that students, parents and voters are calling for in the wake of the country's recent mass shootings.

They work at different hospitals, but Dr. Alan MacIntyre and Dr. Syed Saquib shared a common bond Oct. 1 — they were two of the first trauma surgeons on duty waiting for a rush of causalities from the mass shooting on the Strip.

There are images that will stay with Dr. Deborah Kuhls for a long time. The lethal gunshot wound to the head. The woman who kept her friend alive by keeping her fingers in the bleeding bullet wound all the way to the hospital. And the moment when Dr. Kuhls had to cut open an airway for an obese patient who couldn’t be intubated.

In the days after the shootings at the Route 91 Harvest festival in Las Vegas, many stories emerged of bystander courage. Volunteers combed the grounds for survivors and carried out the injured. Strangers used belts as makeshift tourniquets to stanch bleeding, and then others sped the wounded to hospitals in the back seats of cars and the beds of pickup trucks.

Nearly 48 hours after the deadly shooting rampage in Las Vegas, scores of victims remained in hospitals on Tuesday, with dozens in critical condition, including at least two paralyzed patients, according to hospital officials.

Hospitals in Las Vegas are grappling with a range of patient injuries that reflect the chaos of Sunday evening’s mass shooting, including horrific gunshot wounds and traumas inflicted as victims tried to flee.
