A nurse accused of poisoning patients was an attention-seeker who boasted about how busy his shifts were, a crown court jury has been told.
Nurse Benjamin Geen denies two counts of murder
Benjamin Geen, 25, is on trial for murder and causing grievous bodily harm by administering substances to 18 patients to make them stop breathing.
He did this so he could "enjoy" the thrill of trying to revive them, Oxford Crown Court was told.
Mr Geen, of Banbury, denies two charges of murder and 18 counts of GBH.
Prosecutor Michael Austin-Smith, QC, told the trial how Mr Geen revelled in the drama he is said to have caused at the Horton General Hospital in Banbury.
"He was fond of self-aggrandisement," the QC told the court.
He said Mr Geen had "boasted" about regular action during his shifts.
Mr Austin-Smith said Mr Geen once told a doctor at the hospital: "There is always a resuscitation when I'm on duty."
The prosecutor went on: "Indeed, it was true. Things always seemed to happen when he was on duty."
Mr Geen denies murdering David Onley, 77, of Deddington, and Anthony Bateman, 67, of Banbury.
He also denies 18 counts of causing grievous bodily harm with intent on 18 patients, including the two dead men.
The offences were allegedly committed between 4 December 2003 and 5 February 2004.
The alleged victims were admitted to A&E with mostly non-life-threatening conditions.
They then all suffered unexplained respiratory arrests, requiring emergency resuscitation, the court heard.
Medical experts later agreed that various drugs and other substances, including muscle relaxants used to paralyse patients for surgery, had been administered to deliberately stop them breathing, Mr Austin-Smith said.
The trial continues.
