University Hospital Galway has apologised to the family of a six-year-old girl who died after a failure to diagnose her condition despite four admissions to hospital with low blood sugar.

Hospital staff said they deeply regretted and apologised for failures in the care of Aibha Conroy from Gowla in Connemara who died at on 14 December 2011.

The High Court heard Aibha had been admitted to hospital four times in 2011 but her condition was never properly diagnosed or treated.

She was admitted for a final time in December 2011 with low blood sugar, weakness and vomiting.

She had initially responded to treatment but within 90 minutes suffered respiratory arrest and had to be resuscitated.

She was transferred to Temple Street Hospital where she remained on life support for three days before her death.

She died as a result of brain damage due to a prolonged episode of low blood sugar.

This morning the court approved part of a settlement in the family's case taken against the Health Service Executive for wrongful death.

Mr Justice Kevin Cross was told the family wanted the entire statutory amount of €25,300 to be paid to Aibha's younger sister, Sorcha.

The terms of the remainder of the family's settlement have not been disclosed.

Approving the settlement, Mr Justice Cross said the family had been "very sensible and noble" in relation to the case.

He noted the apology and the corrective action taken by the hospital in appointing an expert to hopefully ensure it did not happen again.

The judge said he hoped the family could take some comfort from that.

The apology issued by UHG General Manager Chris Kane said: "University Hospital Galway together with its clinical and nursing staff wish to extend their sincere and heartfelt sympathy to the Conroy family on the death of their daughter Aibha.

"The hospital deeply regrets and apologises to Mr and Mrs Conroy and their family for the failure to refer Aibha to Crumlin Children's hospital for investigations following her admission in August 2011.

"The hospital acknowledges and greatly regrets the huge trauma and suffering of the Conroy family resulting from the tragic death of their daughter Aibha."
