Mother of Three Becomes Quadruple Amputee After Rare Flesh-Eating Bacteria Strike

May 14, 2010 — -- Katy Hayes' home delivery of her baby girl was uneventful, but the three months since then have been anything but.

Hayes, 41 and a mother of three, is now fighting for her life against flesh-eating bacteria that have so far forced the amputation of her arms and legs.

"Everything was fine," said Katy's husband, Al Hayes, of the days following the Feb. 10 birth of baby Arielle. "She was sore but it was to be expected."

Never did Hayes expect that just a few weeks later, he'd be signing papers to allow doctors to remove his wife's extremities while she slipped in and out of a coma, unaware of what was going on around her.

"It was the worst day of my life," said Al Hayes, 34. "But Katy knows why I had to do it – I had to do it to save her life."

"Before this Katy was completely healthy – she had run a half-marathon and did yoga four days before she gave birth," said Hayes. "She'd work out five times a week."

Al took his wife to the hospital on Feb. 14, when the pain in her abdomen became more acute and persistent. Doctors determined that she had been infected with invasive group A streptococcal disease. In most cases, strep infections result in a skin infection or a sore throat, commonly known as "strep throat," and patients recover with a dose of antibiotics.

But Katy would soon learn that her strain of strep was a very different kind.

"Basically every vein and artery in her body was a giant hole, and she went into complete lung, kidney and liver failure," said Al Hayes. "Her skin started to blister and peel off on all of her extremities; everything from infectious fluids to blood would just weep through her skin."

"Her doctors told me that she had less than a five percent chance of surviving, and that 'nobody comes out of this' because once the snowball effect happens of organs shutting down, there is nothing medical science can do to reverse it," he said.

But the doctors' grim warnings only motivated Hayes to advocate for his wife's medical care even more, determined not to let Katy die without her doctors trying everything possible to save her.

Husband Fights for Wife, as Flesh-Eating Bacteria Ravages Her Body

"My responsibility is if she's going to die on an operating table I'm going to try to save her, we're not going to sit there and let her die, she's going to fight it, that's what she'd want," said Hayes.

Shortly after Katy was hospitalized, Hayes started a blog to chronicle his wife's condition, titled "Katy is Strong." It was a convenient way for him to connect with the rest of their family while still being able to focus on his wife's treatment.

In an emotional blog entry on Feb. 27, the same day he allowed doctors to perform the amputation of Katy's arms and legs, Hayes wrote, "I hope that everyone will understand why I did this. I hope that Katy will forgive me. I hope that I can forgive myself."

Katy, who was not available to speak by telephone with ABCNews.com, told ABC News' Dallas affiliate WFAA that she does understand her husband's decision.

"It's a complete miracle that I'm alive, so I'm so grateful... I'm so grateful," Katy said. "I wouldn't be here for my kids if they wouldn't have taken my arms and legs."

According to Dr. William Schaffner, the chairman of Preventive Medicine at Vanderbilt University Medical Center, the strain of strep that Katy contracted used to be very common hundreds of years ago in women who had just given birth.

Now, Schaffner says, this type of infection is extraordinarily rare.
