A mother whose son died in an alleged stabbing is distributing emergency “bleed kits” to save other people’s lives.

Lisa Petrie’s 22-year-old son John Mcnab was fatally injured on 2 September during an incident in Leith, Edinburgh.

Now the 44-year-old social care worker is raising money for medical packs to treat severe bleeding, and is training other people in Edinburgh to use them.

“I want things to change,” she said. “I don’t want another family to be in this situation.”

Ms Petrie added: “The best way I can describe it is my whole world is a black hole right now.

“We were best pals, me and John, we were inseparable at times, and now I’ve lost my right arm and my left leg.”

More than 3,000 bleed kits can be accessed in community settings across England, but so far very few are available in Scotland.

Lisa became involved at the suggestion of Pauline Bowie from Lower Income Families Together, a community project based in the city’s Muirhouse area.

Pauline has known Lisa for more than 20 years and first met John when he was three.

In the weeks after he died, Pauline heard about a charity named after a young man who was stabbed to death in Birmingham in 2017.

The Daniel Baird Foundation has been arranging for bleeding control packs to be made available in shopping centres, pubs and clubs and transport stations.

“There were 3,000-odd in England and six in Scotland – and three of them are in locked cabinets in train stations,” said Pauline.

“So I showed Lisa and said, why don’t we look at this.”

Lisa and Pauline decided to bulk buy ready-made bleed kits online and have added extra medical equipment such as foil blankets.

Their packs include a tourniquet, a clot bandage, gloves, bandages for sealing wounds, gauze and scissors.

The women have launched a campaign titled “Lives influenced for tomorrow – not in vain” and have put together 24 kits so far.

“They’re not just for stabbings, it’s for intense bleeding,” said Lisa. “It could be from a fall, or a car accident.

“They’re amazing. My ambition is to get them far and wide all around Edinburgh.

“I’ve donated four already, two to pubs, one to Leith Athletics Football Club and one to a Tesco.”

Lisa and six other local mothers took part in an online training course which showed bleed kits being used to deal with major blood loss.

“I’ve done the training so when I’m dispensing these kits I can show people how to use them,” said Lisa.

“The training was very difficult. I think I cried through the majority of it.

“It showed what to do if you have a wound on the arm, a wound on the leg, or an abdominal wound. It was hard, but it gave me more drive to think that these need to be accessible.”

Pauline hopes that people in other areas of Scotland start distributing the kits as well.

“We wanted to do it in John’s memory because we want his death to not be in vain,” she added.

“Everywhere should have them. Next to the first aid kit and the defibrillator, should be a bleed kit.”

A 16-year-old boy has appeared in court charged with John Mcnab’s murder.
