Hospital blunder mum Teresa Innes was wearing a wrist-band warning of her penicillin allergy when she was administered the drug, an inquest heard.

Teresa, who fell into a two-year coma, had suffered a severe allergic reaction five years earlier which was noted on her medical records.

She died after Bradford Royal Infirmary staff prescribed her penicillin, despite her wearing the red band, the hearing was told yesterday.

Health chiefs have already admitted the "error" which left the 38-year-old in a coma for almost two years.

She died on Saturday after medical staff were given permission to stop artificially feeding her.

Bradford Assistant Deputy Coroner James Turnbull yesterday granted permission for the former care worker's body to be released for cremation.

Opening the inquest at Bradford into Teresa's death, he said two investigations were now proceeding, one by the police and one for the Bradford coroner Roger Whittaker.

He said that, "after many months of hardship, difficulty and sadness", the family could finally lay Teresa, of Ternhill Grove, Bradford, to rest.

Mr Turnbull described her death as "very sad - particularly in the circumstances this appears to have occurred."

Coroner's officer Alan Pritchard said Teresa, the mother of a teenage son, died after the head of the High Court Family Division, Dame Elizabeth Butler-Sloss, permitted the withdrawal of all life-sustaining treatment.

A post-mortem examination at Airedale General Hospital at Steeton near Keighley revealed the provisional cause of death as acute brain damage after an allergic shock reaction.

Mr Pritchard said Teresa was known to be seriously allergic to penicillin after suffering a severe reaction to it five years ago, which was noted on her medical records by her GP.

He said she was referred to the accident and emergency department at BRI on September 24, 2001, with an abscess on her left thigh.

Her allergy was noted and a red warning wrist band put on her.

She was due to go to the operating theatre that evening but it was decided to keep her on a ward instead and she was administered with the drug magnapen intravenously.

Mr Pritchard said she suffered a reaction almost immediately.

Calls were made for assistance but by the time the crash team arrived it was too late.

Detective Sergeant John Maguire, of West Yorkshire Police, told the hearing: "It is believed Teresa Innes was wrongly given a dose of penicillin, a drug she was allergic to. Subsequently, she went into a coma.

"The matter was referred to West Yorkshire Police. Inquiries are still on-going into the cause of death and her previous medical treatment."

Mr Turnbull adjourned the inquest and recommended that cremation be allowed to take place.
