The NSW branch of the HSU says paramedics may need to wear body cameras to prevent "idiots" from attacking them.

"While there have been more paramedics employed in recent times you can't prevent cowardice from drunk idiots," union secretary Gerard Hayes told

in a statement today.

"We need a mass education program rolled out but we also need to consider introducing self-activated cameras as a deterrent measure."

The union believes if people knew they were being filmed they would be less likely to attack paramedics who were trying to help those in need.

The riot squad was also called to St Vincent's Hospital overnight where the woman was taken after being removed from the CBD bar.
