An inquest into the death of a two-year-old boy following a medical procedure on his chest has been adjourned and will resume at Dublin City Coroner's Court next Thursday.
Pierce Nowlan from Saggart in Co Dublin, who was a severe haemophiliac, died two years ago after undergoing the procedure at Our Lady's Hospital for Sick Children in Crumlin.
Doctors inserted a device into his chest so that clotting factors could be administered but during the procedure an artery was punctured.
A number of medical witnesses appeared before today's inquest.
A consultant pediatric surgeon who treated Pierce said he had previously carried out more than 1,000 procedures similar to that carried out on Pierce and had never seen complications like those experienced by the two-year-old before.
Professor Martin Corbally said it was a standard procedure which was done very frequently.
Mr Corbally also expressed every confidence in Dr Alan Mortel, who earlier gave evidence at the inquest.
Professor Corbally said that his understanding was that the procedure had gone well and that Dr Mortel was happy with it.
Earlier, Mr Felim Murphy, the surgical registrar on call on the night of the operation, said after a chest tube was inserted to relieve the pressure, 600mls of blood drained out of Pierce's chest over the next ten minutes.
Mr Murphy said the total amount of blood in Pierce's body was 800mls. He added that by 9.30pm that night, Pierce had lost over 1,200mls of blood - or more than one and a half times the amount of blood normally in his body.
Mr Murphy said at 9.30pm Pierce's condition clinically worsened quite dramatically and the surgical team were forced to carry out a rapid open thorocotomy.
They found evidence of blood in his chest, he said, and a haematoma was found near the left subclavian artery.
