UPDATE: Powell River teen with special needs desperately awaits medevac to Vancouver

Preparations are underway to airlift a Powell River teen to Vancouver for a desperately needed MRI, provided Friday’s severe windstorm doesn’t make flying impossible.

The update comes just a day after Shawna Lamden Bennett spoke out about her 14-year-old son Isaac, who has been under heavy sedation at Powell River General Hospital since Sunday.

Isaac has severe autism, and about 10 days ago his school placed him in a bathroom.

He had a strong reaction, and for several minutes banged his head against a wall.

Now doctors think Isaac may have a slow brain bleed and he urgently needs care in Vancouver.

“We’ve had to have some hard discussions. Preparing ourselves for the fact we may not be bringing him home the way we want to,” Lamden Bennett told Global News.

Lamden Bennett says the family was initially told there wasn’t a hospital bed available in Vancouver. A bed has since become available, but now the issue is transportation.

BC Emergency Health Services (BCEHS) responded to Global News in an email, saying “BCEHS received a request to transfer this patient late Monday, and on Wednesday a transfer plan by air ambulance was confirmed. The transfer was scheduled for [Thursday] morning, but poor weather prevented the flight.”

For safety reasons he can’t be transported by ground.

A GoFundMe page has been set up to help pay for Isaac’s care once he and his family are in Vancouver, along with future equipment.
