Researchers have uncovered a medical breakthrough in trauma care that could save the lives of wounded military in remote battlefields or civilians injured in mass casualty events or in rural locations.
For the first time, technology was used to nearly quadruple the “golden hour” during which surgeons could save the life of a large animal with internal traumatic bleeding during emergency ground and air transport.
The research was published on Friday in Intensive Care Medicine Experimental by physician-scientists at the University of Pittsburgh School of Medicine and funded by the US Department of Defence.
“Under normal conditions, if we can get somebody with severe trauma to the hospital within an hour, there’s a good chance that we can save them,” said the project’s scientific lead, Dr Michael Pinsky, of the University of Pittsburgh School of Medicine.
“For the first time in the history of medicine, we took an animal in a critical state on to a helicopter and autonomously brought it back healthier than when it was placed in emergency transport hours earlier.
"The implications this has for treating people in the field with trauma are phenomenal.”

A team from the School of Medicine and computer scientists from Carnegie Mellon University tested a key part of the Trauma Care in a Rucksack (Tracir) system, which fits inside a backpack that could be delivered by drone to remote locations.
A minimally invasive, closed loop algorithm part of the rucksack system, called Resuscitation based on Functional Hemodynamic Monitoring (ReFit), autonomously gave intravenous fluids, blood and drugs to maintain vital functions in animals with a traumatic lethal liver injury for three to five hours without human intervention.
They were taken by ground ambulance and helicopter, and finally returned to the laboratory surgical suite as a demonstration project.
On different days, four fully anaesthetised animals underwent liver laceration in a laboratory surgical suite under approved animal research guidelines.
They were allowed to hemorrhage for 30 minutes before being resuscitated with the ReFit computer algorithm system, which is about the size of a microwave.
Once the autonomous resuscitation device was turned on, the animals received no medical intervention from a human beyond monitoring by an emergency medicine doctor to ensure they remained fully anaesthetised and in no discomfort.

Two of the animals, connected to ReFit, were placed on a stretcher and moved by emergency medical technicians to a hospital helipad where a medical helicopter flew them around western Pennsylvania for several hours to mimic an emergency rescue from a remote location.
The other two were taken by ground ambulance to the Allegheny County Airport where they were then loaded on to a medical helicopter and flown back to the hospital helipad in similarly prolonged flights to simulate long-distance transport.
When returned, the research team confirmed that they could resuscitate the anaesthetised animals autonomously for several hours without human intervention.
“By keeping these animals with a lethal injury alive for up to five hours with a computer driving the resuscitation, you can see how that extends the golden hour,” said principal investigator Dr Ronald Poropatich, director of the Centre for Military Medicine Research and professor of medicine at University of Pittsburgh School of Medicine.
“We are excited about the potential to soon apply this technology to saving the lives of people injured in austere environments.”
The team’s next step is to test transporting ReFit-connected injured animals by unmanned aerial drones to make the process even more effective for rescuing injured people in difficult-to-access locations, such as a mountain or a battlefield.

Ads on social media can 'normalise' drugs
A UK report on youth social media habits commissioned by advocacy group Volteface found a quarter of young people were exposed to illegal drug dealers on social media.
The poll of 2,006 people aged 16-24 assessed their exposure to drug dealers online in a nationally representative survey.
Of those admitting to seeing drugs for sale online, 56 per cent saw them advertised on Snapchat, 55 per cent on Instagram and 47 per cent on Facebook.
Cannabis was the drug most pushed by online dealers, with 63 per cent of survey respondents claiming to have seen adverts on social media for the drug, followed by cocaine (26 per cent) and MDMA/ecstasy, with 24 per cent of people.

Know before you go
- Jebel Akhdar is a two-hour drive from Muscat airport or a six-hour drive from Dubai. It’s impossible to visit by car unless you have a 4x4. Phone ahead to the hotel to arrange a transfer.
- If you’re driving, make sure your insurance covers Oman.
- By air: Budget airlines Air Arabia, Flydubai and SalamAir offer direct routes to Muscat from the UAE.
- Tourists from the Emirates (UAE nationals not included) must apply for an Omani visa online before arrival at evisa.rop.gov.om. The process typically takes several days.
- Flash floods are probable due to the terrain and a lack of drainage. Always check the weather before venturing into any canyons or other remote areas and identify a plan of escape that includes high ground, shelter and parking where your car won’t be overtaken by sudden downpours.

Hidden killer
Sepsis arises when the body tries to fight an infection but damages its own tissue and organs in the process.
The World Health Organisation estimates it affects about 30 million people each year and that about six million die.
Of those about three million are newborns and 1.2 are young children.
Patients with septic shock must often have limbs amputated if clots in their limbs prevent blood flow, causing the limbs to die.
Campaigners say the condition is often diagnosed far too late by medical professionals and that many patients wait too long to seek treatment, confusing the symptoms with flu.

Water waste
In the UAE’s arid climate, small shrubs, bushes and flower beds usually require about six litres of water per square metre, daily. That increases to 12 litres per square metre a day for small trees, and 300 litres for palm trees.
Horticulturists suggest the best time for watering is before 8am or after 6pm, when water won't be dried up by the sun.
A global report published by the Water Resources Institute in August, ranked the UAE 10th out of 164 nations where water supplies are most stretched.
The Emirates is the world’s third largest per capita water consumer after the US and Canada.
What is tokenisation?
Tokenisation refers to the issuance of a blockchain token, which represents a virtually tradable real, tangible asset. A tokenised asset is easily transferable, offers good liquidity, returns and is easily traded on the secondary markets.

What are the main cyber security threats?
Cyber crime - This includes fraud, impersonation, scams and deepfake technology, tactics that are increasingly targeting infrastructure and exploiting human vulnerabilities.
Cyber terrorism - Social media platforms are used to spread radical ideologies, misinformation and disinformation, often with the aim of disrupting critical infrastructure such as power grids.
Cyber warfare - Shaped by geopolitical tension, hostile actors seek to infiltrate and compromise national infrastructure, using one country’s systems as a springboard to launch attacks on others.
