The parents of a four-year-old boy, who died three days after being admitted to hospital, will have to wait another five months to find out what happened in the lead up to his death.

Harry Broughton, from Sheerness, was taken to Medway Maritime Hospital with breathing difficulties in April.

He later suffered a cardiac arrest and was rushed to Evelina Children's Hospital. He died three days later.

Harry's parents, Nicola and Robert, expected to find out what lead to his unexpected death during an inquest at County Hall on Thursday.

But after coroner Catherine Wood assessed the evidence she decided to hold the full hearing in June over three days.

At the hearing in Maidstone, the family's barrister, Ella Davies, raised several concerns regarding the care he received before his death.

She said: "The events leading up to and surrounding Harry's cardiac arrest remain unclear.

"The witness statements that have been provided so far show differences in the hospital staff's recollections of the events.

"There is also evidence of gaps in the training of the resuscitation team."

The Medway NHS Trust was being represented by Molly Walsh-Keaney and said the trust was having difficulty identifying the student nurses who were present during Harry's care.

Ms Walsh-Keaney said: "I have three names that I requested a statement from but I have yet to receive them.

"I only have first names, not surnames. Therefore we have not been able to identify which student nurse was with Harry and his mother, nor get a statement."

After hearing from the lawyers, the coroner requested full statements from witnesses to be sent to her within 28 days.

Coroner Catherine Wood said: "I offer my condolences to Harry's family.

"The pre-inquest may seem cold when discussing Harry's death which is difficult when you've lost someone you love."

Harry's mum, Nicola Broughton, of Shore Close, Sheerness, attended the hearing alongside Harry's dad, Robert, and Harry's grandparents.

Speaking after the hearing, Harry's parents said: "It is just a waiting game now.

"Our barrister has been an amazing help, and if the inquest needs to be delayed so more details can be looked at thoroughly, we'll wait."

Harry, who attended nursery at West Minster Primary School, was taken to Medway Maritime Hospital, Gillingham, early on Monday, April 18, with breathing difficulties.

After several trips to and from the hospital on April 18, his parents were told he had croup – a respiratory infection usually caused by a virus.

It was on that day, while being treated and having a cannula IV inserted, Harry went into cardiac arrest in his mother's arms.

As he was being resuscitated, a mucus plug – a collection of mucus that can reduce airflow in a person's airways – was removed.

It was believed to have been the cause of the cardiac arrest.

Harry was transferred to Evelina London Children's Hospital on Tuesday, April 19.

Doctors said his breathing problems were caused by the flu.

A CT scan confirmed the youngster had suffered from a hypoxic brain injury, something caused by a restricted supply of oxygen.

He died on Thursday, April 21.

His mum said previously: “Harry was a very happy active boy and was very friendly with everyone he met.

“He has a passion for dinosaurs and loved to play outside.”

Medway NHS Trust said it was unable to comment at this stage of the inquest process.
