Wexford General Hospital has said that elective surgery has been cancelled until further notice.
A hospital spokesperson said there were 17 patients on trolleys.
Dr Paddy McKiernan, a consultant physician and medical clinical director at the hospital, says the problem is continuing to worsen.
He says that although they were promised that 19 beds would be fast-tracked for Wexford General Hospital over three and a half years ago, nothing has happened.
