Swedish doctor saves heart attack patient’s life with defibrillator drone

A doctor used a defibrillator delivered by drone to resuscitate a 71-year-old man who had a heart attack in western Sweden.

Emergency services dispatched the drone followed by an ambulance when Sven, a retiree who asked for his last name to be withheld, collapsed in early December while shovelling snow outside his home in the town of Trollhättan.

“Everything from the first 112 call to the drone getting the signal to start and go took about 15-30 seconds and then the whole process took about three and a half minutes,” Sven told AFP.

By lucky coincidence a doctor, Mustafa Ali, was driving past. He stopped and began performing CPR as Sven’s wife called emergency services, and was there on the spot when the drone arrived with the defibrillator to help restart Sven’s heart.

Ali said the drone “really helped” in saving the man’s life, as it was used in combination with quick CPR and medicines administered in the ambulance, which arrived minutes later.

“I think it’s a really good tool. Especially when it comes to patients that are far away from the nearest hospital,” Ali told AFP.

The defibrillator, which gives electric shocks to the heart of a patient in cardiac arrest, was lowered to the ground via a winch, meaning the drone didn’t need to land to deliver the device.

The use of medical drones is part of trial run by Everdrone in the area around Gothenburg, and is being developed in collaboration with the Center for Resuscitation Science at medical university Karolinska Institutet, emergency service operation SOS Alarm and regional health authority Västra Gotaland.

Everdrone stated its network can currently reach 200,000 residents in Sweden and “is expected to expand to more locations in Europe during 2022”.

In future the unmanned aircraft could be fitted with other medical equipment.

“You could imagine these drones delivering trauma kits in various situations… going to hard to reach islands or other places where it’s hard to go at all,” Mats Sällström, CEO of Everdrone, told AFP.

“We started with the defibrillator because it’s such a time-critical event” where a drone can really make a difference, he added.

How to avoid the Swedish disease of ‘hitting the wall’

David Crouch, who “hit the wall” himself, looks at what you can do to avoid this uniquely Swedish condition, which causes thousands to take long-term sick leave. 

How to avoid the Swedish disease of ‘hitting the wall’

At first I bought one of those super-bright therapy lamps. Perhaps it was the winter darkness that was making me feel this way. In my head, it felt like trying to wade through thick, sticky mud. Like permanently cycling uphill. 

There were times when I just had to stay in bed, especially at the weekends, or take a long nap in the afternoons. Perhaps I was just getting old? I lost my lust for reading, my alcohol intake went up. I developed a short fuse and would lose my temper over nothing.

Maybe I was depressed? I went to vårdcentralen, the local healthcare centre. They tried various drugs on me, to little effect. Eventually they sent me to a psychologist. “You’re not depressed, you’re clinically exhausted,” she said. “You should do less.” 

It was a good diagnosis, but telling me to do less was like asking a fly to crawl out of a spider’s web. I needed help. My life required major surgery. 

As I neared my actual burnout, I tried plunging into very cold water. I was like Rutger Hauer’s character in Blade Runner, who senses that he is dying and drives a nail through his hand to keep himself alive

Last week, we looked at Sweden’s epidemic – in which I am a statistic – of what they call “hitting the wall”, known among doctors as exhaustion syndrome (utmattningssyndrom). The medical term in English is “exhaustion disorder” (ED). 

My experience with the condition shows how hard it can be to identify, even for health professionals.

It all started in the mid-1990s, when doctors in Sweden realised they were seeing people with a common set of symptoms.

Patients were very tired, their heads were in a mess, they found it hard to read or absorb information, and they felt generally crappy. Sweden had been through a deep economic crisis and many people had lost their jobs. For many, this was a period of major upheaval. 

From this, a new diagnosis emerged for exhaustion caused by chronic stress; it was officially recognised by Sweden’s medical establishment in 2005. Since then it has been gradually – and unevenly – implemented in clinical practice. There is a considerable overlap between ED and clinical burnout, which is recognised abroad. However, ED is unique to Sweden in that it includes not only work-related stressors but also those that occur in private life.

According to Sweden’s National Board of Health and Welfare, someone may have ED if they experience all three of A, B and C below:

A. Physical and mental symptoms of fatigue for at least two weeks, with symptoms having developed as a result of one or more identifiable stressors that have been present for at least six months

B. A clear picture of impaired mental energy, reflected in reduced initiative and endurance, or extended time necessary to recover from mental strain

C. At least four of the following symptoms should have been present daily during the same two-week period. These should cause clear suffering or impaired function at work or in other social contexts, and should not be caused by drugs, medicines or disease:

  1. Difficulties with concentration or memory
  2. Significantly reduced ability to handle tasks or to do things under time pressure
  3. Mood swings or irritability
  4. Significant physical weakness or fatigue
  5. Physical symptoms such as chest pain, palpitations, stomach upset, dizziness or sound sensitivity
  6. Sleep disturbance.

“Dizziness and sound sensitivity”? Yep. “Significant physical weakness”? From cycling 50km for fun, I went to finding it exhausting to take a gentle stroll.

Some clinicians find the ED diagnosis problematic. There are no studies to show how ED is distinct from depression or even how it differs from normal tiredness among healthy people, as Christian Rück, professor of psychiatry at Stockholm’s Karolinska Institute, points out.

The danger is that we medicalise symptoms that are just part of normal life, he says, defining people as sick when actually they are not, and subjecting them to ineffective or unnecessary treatments. 

The uncertainties around ED mean that Sweden doesn’t even know for sure how many cases there are, or whether the number is rising or falling. “Many doctors do not accept the diagnosis, and not all vårdcentralen use it,” says Kristina Glise at Gothenburg’s Institute for Stress Medicine, who was one of the group of researchers who originally developed the ED diagnosis.

It is also unclear what treatments work for which symptoms, other than changing how people work. “We have not found measures that can shorten the illness other than at the workplace,” Glise says. Since 2018, employers have been legally responsible for taking an active part in the rehabilitation of employees diagnosed with ED.

Swedish trade union Unionen offers the following tips for spotting someone who is heading “into the wall”. The victims themselves are usually not so good at recognising the signs:

  • Fatigue and sleep disorders: they commonly to go to bed late and get up early to catch up on work. The result is that they constantly feel tired
  • Careless with diet: “I don’t have time to eat properly” is the common refrain 
  • Regular exercise and social events are not prioritised
  • Headaches and pain in the body, especially tension in the neck and shoulders
  • Sensitivity to sound
  • Slightly irritated, anxious or depressed, with a shorter fuse than usual
  • Poor memory and difficulty concentrating.

During the two years of my battle with ED, I had superb care from a local occupational therapist. She taught me to recognise my symptoms and to re-organise my life so that I learned to work regular hours, take frequent breaks and exercise, and find effective methods to de-stress and relax.

But could I have avoided hitting the wall in the first place?

I regret that nobody was able to warn me of what was coming if I didn’t take the necessary steps. Hopefully, this and my previous article might encourage you to do so.
