A coroner is expected to deliver a verdict in the case of Malcolm Green who died after an operation at Withybush Hospital in June 2012. The hospital have already admitted "avoidable and unacceptable delays" in his treatment.
The inquest heard evidence that the 82 year old would probably have survived if doctors had acted more quickly. Mr Green became increasingly unwell after undergoing surgery for bowel cancer.
His family say staff failed to notice the deterioration in his condition and that he died of internal bleeding and organ failure because the surgeon who was supposed to be treating him left to go to a meeting.
A hospital radiographer let her 10-year-old son start an X-ray machine on a schoolgirl, a disciplinary hearing has heard. Tamitha Grey, 46, stood behind the X-ray machine as her son was heard to ask: "Are we ready yet, mum?".
The 15-year-old patient's shocked family heard her reply: "No...OK" before the radioactive machine whirred into life. The schoolgirl's mother Nicola Jones said: "It was an incredible thing to see. I still can't believe it happened."
Mrs Jones works as an ultrasound technician at the same hospital - Withybush Hospital in Haverfordwest, Pembrokeshire - where her daughter was X-rayed for a suspected broken wrist. The boy was then taken away, before Mrs Grey performed a second X-ray on the girl.
The hearing was told Mrs Grey took her son into hospital after his after-school rugby match had been called off. She has already been given a formal written warning after an internal investigation where she admitted letting her son press the button to start the X-ray machine.
Now she could be struck off for misconduct in the hearing of the Health Care Professions Council.
She accepted the HCPC's allegation she permitted an unqualified and unauthorised person to initiate the exposure of a patient to ionising radiation on May 9 last year.
She also admitted permitting a member of the public to be present during a clinical examination, and that both allegations constituted misconduct. But she denied that her fitness to practise as a radiographer was impaired by her actions.
The hearing in Cardiff is continuing.
