Death of six-month-old Kyran Day due to medical failure, inquest finds

A six-month-old baby boy who died in hospital from a lack of oxygen to the brain died because doctors failed to detect what was wrong with him and act on it in a timely manner, a NSW coroner has found.

Kyran Day was diagnosed with gastroenteritis at Nowra's Shoalhaven Hospital on October 19, 2013, but died three days later in Sydney Children's Hospital.

The cause of death was listed as hypoxic ischaemic encephalopathy, NSW Deputy State Coroner Teresa O'Sullivan found on Wednesday.

"I offer the family my heartfelt condolences," Ms O'Sullivan told Kyran's parents Naomi and Grant Day, who had attended every day of the inquest.
