Mayra Cabrera died within hours of her son Zac's birth in 2004
A hospital in Swindon is to be prosecuted on health and safety charges over the death of a nurse shortly after she gave birth.
Mayra Cabrera, a 30-year-old theatre nurse, had a drug used in epidurals pumped into her arm at the Great Western Hospital on 11 May, 2004.
She died of a heart attack after giving birth to her son, Zac, who survived.
The Health and Safety Executive has told the hospital it is prosecuting over alleged "safety breaches".
Sue Rowley, director of nursing at the Great Western Hospital NHS Trust, said: "The Trust have been summoned to appear at the magistrates court at a future date.
"We regret the additional distress this case causes Mayra's family and friends and we will minimise this as much as possible by seeking a swift resolution to the case."
Mrs Cabrera , who came to the UK from the Philippines in 2002, died from a heart attack caused by the drug Bupivacaine, which should be administered as an epidural but was injected into her arm.
Last year, an inquest deemed her death unlawful.
Coroner David Masters made a number of recommendations including better labelling of drugs and enforced annual appraisals for midwives.
Ms Rowley said: "There have been a number of independent investigations into the circumstances surrounding the death and we have made significant improvements to the safety of maternity services."
Mrs Cabrera's widower, Arnel, was told he could no longer stay in the UK after his wife's death as she was no longer working.
However, in August 2008 he won his fight to remain in the country.
