NEW mother Mayra Cabrera was unlawfully killed when an epidural drug was injected into her arm an inquest jury has found today.

The 30-year-old theatre nurse died shortly after giving birth to son Zac at the Great Western Hospital on May 11, 2004.

Following the delivery, Bupivacaine, a potent epidural anaesthetic, was wrongly fed into a vein in her hand - it should have been injected into her spine.

She died less than an hour after her son was born from a heart attack.

The jury said gross negligence by Swindon and Marlborough NHS Trust, specifically sub-standard storage of drugs in the maternity unit, had led to the death.

Returning the verdict, the jury foreman said: "Mayra Cabrera was killed unlawfully - gross negligence/manslaughter - storage and administration."

The jury of six women and three men took 17 and a half hours to reach its majority verdict.
