London, Nov 15: The inquest into the death of Diana, Princess of Wales has heard battled to save her life after the car crash in the Pont de l'Alma Tunnel on August 31, 1997.

Anaesthetist Daniel Eyraud described how the team of eight doctors at Paris's Pitie-Salpetriere Hospital worked for nearly two hours to keep the royal alive, giving her massive doses of adrenaline, repeated electric shocks and extended heart massages after her hear had stopped beating.

Diana’s heart had already stopped once after the accident, but she had been resuscitated. However, at 2.10am, moments before surgeons opened her chest to try to relieve the pressure, the princess’ heart stopped for a second time.

"We had to perform cardiac massage at the same time as the surgeon was operating, looking for the source of the haemorrhage, " the Daily Mail quoted Dr Eyraud, as saying in a statement read to Diana's inquest in London.

"Throughout the entire operation, cardiac massage was performed and rapid transfusions and drips administered, with massive and repeated doses of adrenaline being injected.

"We also administered several electric shocks during resuscitation in order to get her heart restarted, but to no avail. "

At 4am, three and a half hours after the crash, doctors finally gave up the fight and pronounced Di dead.

"We decided by common consent to stop heart massage as it was completely impossible to restore cardiac activity after such a long period, " Dr Eyraud said.

"I personally believe we did everything possible to save the princess. "

The inquest also heard from Philippe Boyer, a former fireman who treated Diana as she lay in the car.

"She said 'My God' several times, it was repeated, but the other things she said I couldn't understand, " said Mr Boyer.

Mr Boyer revealed that at the time Diana was in the car, her pulse was "fine and quite strong" and her breathing appeared normal.

Her only visible injury was to her right shoulder and there was no blood on her face.

However, her heart stopped minutes after firemen pulled her out of the car at around 1am. She was resuscitated as she was being taken to hospital but her condition worsened.

Dr Eyraud said: "I knew she was in a serious condition, but had no further information. "

"She was in shock, but nevertheless had a heart rhythm. Her blood pressure was very low but her heart was still beating. " (ANI)
