The Irish Nurses and Midwives Organisation has written to the HSE seeking details of the investigation it is going to conduct into the death of a new born baby boy over the weekend.

The baby was born in Cavan General Hospital on Thursday, but died in the Rotunda Hospital in Dublin on Saturday.

His death is being investigated by the Dublin City Coroner, while the HSE is setting up a team to review the care given to the baby and his mother.

This evening, the INMO’s Tony Fitzpatrick confirmed his organisation had written to the HSE seeking details of who would be on this review group, and what its terms of reference are.

Mr Fitzpatrick said it was essential that the review had independent members.

It should not be the case that the hospital would investigate itself, he said.

The coroner's office requested on Monday that an autopsy be carried out on the baby's remains. It is believed that has now been done.

The coroner will decide whether to hold an inquest into the boy's death after he receives a report from the pathologist.

It is understood that the mother was in labour in Cavan General Hospital last week when a decision was then made to deliver the baby by Caesarean section.

However, another Caesarean section was already being carried out in the main theatre and so a second theatre had to be readied.

When the baby was born he was critically ill.

He was then taken to the National Neonatal Unit at the Rotunda Hospital, where he died a short time later.

The HSE has expressed its condolences to the baby's parents and said that it would "closely examine the circumstances of this case".
