In the beginning of the COVID-19 pandemic’s first wave, Dr. Joseph Dahine and his colleagues may spend over an hour huddled across the bedside of a affected person within the ICU in Laval, Que., brainstorming remedy choices.
There have been no textbooks to inform them what to do, in order that they grew to become medical detectives as Quebec confronted a surge of instances, studying all the things they might concerning the physiology and nuances of COVID-19 to avoid wasting lives.
Dahine, an intensive care specialist at Cité de la Santé hospital, mentioned he labored gruelling, 12-hour days by the spring, huddling along with his workforce on breaks.
“We experimented quite a bit,” he mentioned.
What was clear from the outset was that COVID-19 was no regular respiratory illness. Typically, sufferers would are available in with extraordinarily low oxygen saturation ranges.
“Often that is an emergency. The affected person is dying, they’re gasping for air and you might want to put the tube instantly,” mentioned Dahine.
However these sufferers did not seem like in misery.
“It is bizarre to inform somebody, ‘OK, we will put you in a coma now and we will put a tube down your throat they usually’re like, ‘Properly, I am wonderful,'” mentioned Dahine.
Over time, Dahine and his workforce realized extra about when to intubate a COVID-19 affected person.
In some instances, they had been in a position to keep away from it altogether. They practiced the identical restraint after they eliminated somebody from a ventilator.
Though the World Well being Group had warned it took COVID-19 sufferers as much as three weeks to get well, Dahine recollects a 60-year-old affected person who, 4 days in, appeared to not require intubation. The medical workforce determined to take him off the ventilator.
However after they started to dial down the stress that stored the affected person’s airways open, his lungs could not take it. They needed to rapidly carry him again as much as 100 per cent oxygen.
The person’s lungs had been nonetheless too fragile.
“We’re not shocked anymore when a affected person deteriorates once we resolve to wean them,” mentioned Dahine.
“We would have liked to be extra affected person for the irritation and the illness to enhance.”

However there are nonetheless curveballs. Irritation of the lungs is not all the time the wrongdoer if a affected person begins to deteriorate.
COVID-19 sufferers within the ICU are typically vulnerable to blood clots and kidney illness, which requires dialysis.
After a comparatively quiet summer time, a affected person got here in to the Laval hospital final month with cardiogenic shock — a severe situation that happens when the center can’t pump sufficient blood and oxygen to the mind, kidneys and different very important organs.
“That first case, it scared us,” mentioned Dahine. He was fearful cardiac problems could be the defining characteristic of COVID-19’s second wave.
However to date, it was simply that one affected person — and that affected person pulled by.
What works, and what does not
It’s troublesome for Quebec‘s medical doctors to measure the diploma to which improved strategies have helped lower the mortality fee of COVID-19 and size of hospital stays, given the multitude of things at play.
(In July, the World Well being Group estimated the an infection fatality fee at 0.6 per cent.)
The province’s second wave of COVID-19 has seen a rise in instances amongst youngsters and folks of their 20s, who’re much less more likely to undergo severe problems from the virus and, in lots of instances, don’t remain as lengthy in hospital.
Whereas medical doctors say there’s nonetheless a lot to study concerning the virus, new therapies and methods have helped.
Medicines akin to dexamethasone, an affordable steroid, and remdesivir, an antiviral drug, have been proven in scientific trials to assist sufferers with COVID-19.
Dr. Matthew Oughton, an infectious illnesses specialist on the Jewish Normal Hospital in Montreal, mentioned each these medicine have helped enhance restoration instances.
“We additionally know issues that do not work,” he mentioned, mentioning, like Dahine, not placing a affected person on a ventilator straight away. Generally, the answer is as easy as having a affected person relaxation on their abdomen, relatively than their again.
Oughton mentioned the sufferers are, on the entire, spending much less time in hospital. Nonetheless, the variety of folks being admitted has climbed in current weeks, significantly in sure areas, akin to Quebec Metropolis.
“I would not say that they’ve skyrocketed up, however it’s making it difficult,” he mentioned.
“It appears to be like like we could possibly hold management on this. I say that with nice trepidation, although.”
Dr. Horacio Arruda, Quebec‘s public well being director, on Monday mentioned the mortality fee from problems of the virus appears to be enhancing within the province, and that new therapies are particularly efficient in younger folks.
“However it’s nonetheless a illness that, when you’ve got any underlying well being circumstances, will be very troublesome. And even for those who survive, you possibly can have pulmonary issues, agnosia,” Arruda mentioned at a information convention Monday.
“It is nonetheless a severe illness, and I feel stopping it’s higher than getting it.”
Preserving sufferers out of the hospital
There are additionally indicators of enchancment outdoors the hospital setting.
Dr. Nicole Ezer, a researcher within the respiratory illnesses program on the McGill College Well being Centre, is amongst these engaged on new medicines that may hold folks from having to be admitted.
Ezer is testing the effectivity of ciclesonide, an inhaled and nasal steroid drug at the moment used for bronchial asthma and nasal rhinitis, on sufferers with milder signs of COVID-19.
If profitable, the remedy would enable medical doctors to deal with sufferers with extra gentle signs at dwelling — and keep away from them having to go to hospital.
“I feel on the whole there’s a number of enthusiasm for vaccines, however we do not know but the efficacy of the vaccine,” mentioned Ezer, who can also be an assistant professor at McGill College.
“For us, COVID is all the time going to be current.”
Regardless of all the things medical doctors have realized concerning the illness, Dahine says it is too quickly to inform if it can imply fewer deaths for these sufferers that have to be hospitalized.
“Flattening the curve within the spring, ensuring that every hospital didn’t have too massive of an inflow of sufferers on the similar time, prevented us from making errors that will have gotten us the next mortality fee,” he mentioned.

The emotional burden on the households of individuals hospitalized with COVID-19 is one thing Dahine will always remember.
His hospital alone has seen households that can be ceaselessly modified by the illness. In a single case, a pair got here in — the spouse made it, however the husband didn’t. There was additionally a son and his mom. The son survived, however his mom died.
Dahine nonetheless does not know why some sufferers took a flip for the more serious even after they had the identical remedy, physician and assist workforce.
“I am unable to take solace in the truth that it is the affected person’s fault,” mentioned Dahine. “Definitely it is the illness’s fault.”
