ECMO Life Support Is a Last Resort for Covid, and in Short Supply in South

Hospital discharge day for Phoua Yang was extra like a pep rally.

On her means rolling out of TriStar Centennial Medical Center in Nashville, Tennessee, she teared up as streamers and confetti rained down on her. Nurses chanted her title as they wheeled her out of the hospital for the primary time since she arrived in February with covid-19, barely capable of breathe.

The 38-year-old mom resides proof of the facility of ECMO — a technique of oxygenating a affected person’s blood exterior the physique, then pumping it again in. Her story helps clarify why a scarcity of educated workers members who can run the machines that carry out this extracorporeal membrane oxygenation has grow to be such a pinch level as covid hospitalizations surge.

“One hundred forty-six days is a long time,” Yang stated of the time she spent on the ECMO machine. “It’s been like a forever journey with me.”

For almost 5 months, Yang had blood pumping out a gap in her neck and working via the rolling ECMO cart by her mattress.

ECMO is the very best stage of life assist — past a ventilator, which pumps oxygen through a tube via the windpipe, down into the lungs. The ECMO course of, in distinction, principally capabilities as a coronary heart and lungs exterior the physique.

The course of, extra typically used earlier than the pandemic for organ transplant candidates, just isn’t a therapy. But it buys time for the lungs of covid sufferers to heal. Often they’ve been on a ventilator for a whereas. Even when it’s working effectively, a ventilator can have its personal unwanted effects after extended use — together with nerve harm or harm to the lung itself via extreme air strain.

Doctors typically describe ECMO as a method to let the lungs “rest” — particularly helpful when even air flow isn’t totally oxygenating a affected person’s blood.

Many extra individuals may benefit from ECMO than are receiving it, which has made for a messy triaging of therapy that might escalate in the approaching weeks because the delta variant surges throughout the South and in rural communities with low vaccination charges.

The ECMO logjam primarily stems from simply how many individuals it takes to care for every affected person. A one-on-one nurse is required, 24 hours a day. The staff shortages that many hospitals in sizzling zones are dealing with compound the issue.

Yang stated she generally had 4 or 5 scientific workers members serving to her when she wanted to take a day by day stroll via the hospital halls to maintain her muscular tissues working. ECMO is uncommon as life assist, as a result of sufferers will be acutely aware and cell, in contrast to sufferers on ventilators who typically are sedated. This presents its personal challenges, nonetheless. For Yang, one individual’s job was simply to verify no hoses kinked as she moved, for the reason that machine was actually preserving her alive.

Of all of the sufferers handled in an intensive care unit, these on ECMO require essentially the most consideration, stated nurse Kristin Nguyen, who works in the ICU at Vanderbilt University Medical Center.

“It’s very labor-intensive,” she stated one morning, after a one-on-one shift with an ECMO affected person who had already been in the ICU three weeks.

The Extracorporeal Life Support Organization stated the common ECMO affected person with covid spends two weeks on the machine, although many physicians say their sufferers common a month or extra.

“These patients take so long to recover, and they’re eating up our hospital beds because they come in and they stay,” Nguyen stated. “And that’s where we’re getting in such a bind.”

Barriers to utilizing ECMO usually are not merely that there aren’t sufficient machines to go round or the excessive value — estimated at $5,000 a day or considerably extra, relying on the hospital.

“There are plenty of ECMO machines — it’s people who know how to run it,” stated Dr. Robert Bartlett, a retired surgeon on the University of Michigan who helped pioneer the technology.

Every youngsters’s hospital has ECMO, the place it’s often used on newborns who’re having hassle with their lungs. But Bartlett stated that, earlier than the pandemic, there was no level in coaching groups elsewhere to make use of ECMO once they may use the know-how solely a few occasions a yr.

It’s a pretty high-risk intervention with little room for error. And it requires a round the clock group.

“We really don’t think it should be that every little hospital has ECMO,” Bartlett stated.

Bartlett stated his analysis group is working to make it so ECMO will be provided exterior an ICU — and probably even ship sufferers house with a wearable machine. But that’s years away.

Only the most important medical facilities provide ECMO at the moment, and that has meant most hospitals in the South have been left ready to switch sufferers to a main medical middle in the course of the current pandemic surge. But there’s no formal method to make these transfers occur. And the bigger hospitals have their very own covid sufferers eligible for ECMO who could be keen to attempt it.

“We have to make tough choices. That’s really what it comes down to — how sick are you, and what’s the availability?” stated Dr. Harshit Rao, chief scientific officer overseeing ICU docs with doctor companies agency Envision. He works with ICUs in Dallas and Houston.

There is not any formal course of for prioritizing sufferers, although a nationwide nonprofit has started a registry. And there’s restricted information on which components make some covid sufferers extra more likely to profit from ECMO than others.

ECMO has been used in the United States all through the pandemic. But there wasn’t as a lot of a scarcity early on when the individuals dying of covid tended to be older. ECMO is never used for anybody aged or with well being circumstances that will hold them from seeing a lot profit.

Even earlier than the pandemic, there was intense debate about whether or not ECMO was simply an costly “bridge to nowhere” for most sufferers. Currently, the survival rate for covid sufferers on ECMO is roughly 50% — a determine that has been dropping as extra households of sicker sufferers have been pushing for life assist.

But the calculation is completely different for the youthful individuals who make up this summer time’s wave of largely unvaccinated covid sufferers in ICUs. So there’s extra demand for ECMO.

“I think it’s 100% directed at the fact that they’re younger patients,” stated Dr. Mani Daneshmand, who leads the transplant and ECMO applications at Emory University Hospital.

Even as massive as Emory is, the Atlanta hospital is popping down a number of requests a day to switch covid sufferers who want ECMO, Daneshmand stated. And calls are coming in from everywhere in the Southeast.

“When you have a 30-year-old or 40-year-old or someone who has just become a parent, you’re going to call. We’ve gotten calls for 18-year-olds,” he stated. “There are a lot of people who are very young who are needing a lot of support, and a lot of them are dying.”

Even for youthful individuals, who are inclined to have higher possibilities on ECMO, many are debilitated afterward.

Laura Lyons was a comic with a day job in New York City earlier than the pandemic. Though simply 31 when she got here down with covid, she nearly died. ECMO, she stated, saved her life. But she might by no means be the identical.

“I was running around New York City a year and a half ago, and now I’m in a wheelchair,” she stated. “My doctors have told me I’ll be on oxygen forever, and I’m just choosing not to accept that. I just don’t see my life attached to a cord.”

Lyons now lives at her dad and mom’ home in central Massachusetts and spends most days doing bodily remedy. Her battle to regain her energy continues, however she’s alive.

Since it’s sort of the wild West to even get somebody an ECMO mattress, some households have made their desperation public, as their cherished one waits on a ventilator.

As quickly as Toby Plumlee’s spouse was placed on a ventilator in August, he began urgent her docs about ECMO. She was in a northern Georgia group hospital, and the household searched for assist at greater hospitals — wanting 500 miles in each path.

“But the more you research, the more you read, the more you talk to the hospital, the more you start to see what a shortage it really is,” he stated. “You get to the point, the only thing you can do is pray for your loved one — that they’re going to survive.”

Plumlee stated his spouse made it to sixth in line at a hospital 200 miles away — TriStar Centennial Medical Center, the place Phoua Yang was ending her 146-day ECMO marathon.

Yang left with a miracle. Plumlee and their youngsters had been left in mourning. His spouse died earlier than ever getting ECMO — a few days after turning 40.
