Dr George Findlay from University Hospital of Wales has given ITV News an update on the condition of those still being treated, including a nine-year old girl still in intensive care.
She's seriously ill in our intensive care unit, currently receiving treatment to try and reduce her injuries - but really it is a matter of time and taking things day-by-day.
This was a serious road traffic crash and the injuries are the kind of things you would expect - bone injuries and head injuries.
