[From the scene] ‘Don’t give COVID-19 any chances’
Meet pandemic dream team saving Korea’s sickest patients from COVID-19

ANYANG, Gyeonggi Province -- At critical case wards across Korea, health care workers have put their lives on the line quite literally every day for the past year and a half as they battle the pandemic.
The squad of doctors and nurses at the Hallym University Sacred Heart Hospital’s center for extracorporeal membrane oxygenation, or ECMO -- the last stage of life support for the sickest patients -- is weathering “the worst of COVID-19” on a daily basis.
The ECMO center’s chief and thoracic surgeon Dr. Kim Hyoung-soo, 53, led a double-lung transplant surgery that ended up saving the life of a 50-something COVID-19 survivor in June last year -- a procedure that is the first of its kind in the country.
Kim, who has led the center since its inception seven years ago, said: “I always say, try not to give COVID-19 any chances.”
When Kim walked into his office to speak with The Korea Herald at around 3:30 p.m. last Thursday, he was soaked in sweat, having just put two newly-transferred patients on ECMO in the isolation unit in the emergency room a floor below.
Neither tested positive for COVID-19 in results that came out later. But until a negative status is confirmed, the same set of precautions for patients with COVID-19 needed to be followed.
The hospital is among the few in all of Korea to be equipped with a dedicated ECMO center and specialized staff -- and thus has naturally become the destination for patients with critical care needs that other hospitals cannot provide.
Kim said he typically changes in and out of a “Level D” hazmat suit four to five times a day, working with patients at the hospital as well as those who have been sent there from areas near and far.
“We have never turned down patient transfer requests, until at one point in August when we ran out of beds,” he said.
Since mid-July, after the fourth wave took off, the hospital’s ECMO center has been operating at near full capacity. Until about two weeks ago, all of its 11 beds were fully occupied, eight of them by COVID-19 patients.
The Korean Society for Thoracic and Cardiovascular Surgery forecasts even higher ECMO demand later this month, which is around the time the government expects to see a slowdown in spread.
“The timeline for a COVID-19 surge in critical care is around 10 to 14 days behind that for overall caseloads,” Kim said, which means that another peak may be yet to come.
Kim’s office, about 16 square meters large and windowless, functions as sort of a common room for the ECMO staff who have been in “crisis mode” throughout the summer. He and the head nurse-ECMO coordinator Lee Sun-hee, 51, have not gone home to their families in the while, staying instead at the hospital dorm.
Their days are attuned to emerging patient needs. For Kim, late night and early morning hours are the busiest, and 5 to 8 a.m. -- his “usual downtime” -- is when he can sleep with the fewest interruptions.
Asked how long her shift was, Lee replied matter-of-factly: “I don’t have a shift. I’m on call 24 hours a day.” The hospital director recently got her a studio flat in the neighborhood because she had been constantly on the job.
This year’s Chuseok, which is supposed to be a big deal as the first national holiday coming around since the national vaccine program launched, won’t be different from any other days for Lee. With her patients at the hospital was where she planned to be.
“At the end of the day, there is no other place I’d rather be,” she said.
A solemn quiet filled the hospital’s surgical intensive care unit late afternoon that day. The only noise was the restless movements of the medical staff and the soft, rhythmic beeping of the machines keeping patients alive. The air smelled medicinal, and a bit like blood.
This is where patients who are still critically sick after two consecutive negative tests are taken to as their isolation is lifted, to make room for incoming infectious patients. On each of the 21 beds in the unit was a sedated body tied to a jumble of tubes, wires and bags.
Lee said the nurses did everything for the patients, from repositioning them occasionally to prevent bed sores to helping them in and out of “adult briefs.” ECMO and other mechanical support such as continuous renal replacement therapy, called CRRT for short, also required constant monitoring.
While working with her patients, Lee tries to be “emotionally there for them.”
“One moment you are admitted to a quarantine facility as a ‘mild’ COVID-19 case. Then, the next thing you know, you are in an isolation ward battling for your life. Every person you see looks like an alien dressed in full-body suits,” she said.
“It’s a very frightening situation when you think about it.”
Even then, there was a limit to how long a person can stay on ECMO, which is an “extremely invasive” procedure. “About two to four weeks is the max,” she said. Any longer could lead to deteriorating complications.
Kim said he tries not to remember his patients’ names. The odds of survival for patients placed on ECMO are about 50-50. In a setting where death is so constant, his intuition is to remember as little as possible.
“You learn not to dwell on things too much and lose perspective,” he said.
As the chief doctor he is often the one to tell patients’ loved ones that they may not make it. Although hospital visits are barred for safety concerns, a brief moment, lasting perhaps a meager five minutes, is granted for a last goodbye.
In the final hours or days of life, patients are not conscious -- so whatever interaction takes place in the short time is one-way -- and their appearance is usually altered from enduring invasive support.
Layers of protective gear allow for no real contact between patients and their visitors. Utterances of goodbyes are smothered beneath masks. Goggles turn foggy and tear-filled. Then, again for safety concerns, there can be no proper funerals.
While it’s true the elderly and the medically frail are most vulnerable, Kim said he was witnessing younger and seemingly healthy people wither away from the ravages of the virus at a growing rate. One patient he lost just last week was barely 40.
“Whereas before it was mostly senior patients that ended up on ECMOs, patients admitted in the past couple of months were in their 30s to 50s -- in their 60s at most. At other hospitals I’ve heard some were under 30,” he said. With older people protected by vaccination, the age groups that the rollout has yet to reach were taking the hit.
“No one can really explain why a young, apparently healthy person would suddenly fall very sick,” he said. “Then once you get sick, a lot depends on chance.”
Out of six of the hospital’s patients that were listed for lung transplants after COVID-19, just two had received them. While one of the two recovered, the other died about five days later. Three died while waiting. One was still holding on at the ICU and waiting.
Some patients, after recovery, have told the team COVID-19 was “nothing like what they imagined.” “They thought it was like the flu. They found out the hard way that it wasn’t,” Lee said.
Lee’s younger sister Yong-hee, 49, who is the head nurse at the same hospital’s emergency ICU said the pandemic workload meant “dealing with COVID-19 on top of regular emergencies such as car crash injuries, heart attacks and so on.”
“COVID-19 doesn’t put a stop on other health issues,” she said.
Dr. Park Sung-hoon, a pulmonary and critical care medicine specialist, said as younger patients tend to fare better, the survival rates have improved over the current wave. But the total number of critical care hospitalizations was now greater than ever, and rising.
A ward full of young patients, as opposed to elderly patients nearing end of life, like before, in some ways makes the fight harder for medical workers. “Now so many of them are ‘saveable.’ So we’re going extra lengths to see them recover. And any loss feels that much more devastating.”
Park said the biggest challenge was recruiting a trained workforce.
“Not all licensed health care providers are capable of looking after ICU patients. Before winter dawns, we have to be prepared for a scenario where our resources are outstretched.”
