An expert anaesthetist giving evidence for the doctor accused of killing Michael Jackson admitted today that the music star's medical care was not up to standard.
Dr Paul White was repeatedly cross-examined about the ways in which Dr Conrad Murray had broken guidelines and rules in his treatment of Jackson.
Dr White acknowledged that the type of pulse monitor that Murray was using on Jackson's finger was inadequate to properly monitor the singer when the physician left the room.
Murray, who denies involuntary manslaughter, has acknowledged he was giving Jackson doses of the anaesthetic propofol in the singer's bedroom as a sleep aid. He told police that he left Jackson's room for two minutes on June 25, 2009, and returned to find the pop superstar unresponsive.
Dr White also said he would not leave the room if he were treating a patient who had indicated he liked to inject propofol into himself, as Murray claims that Jackson had told him.
Deputy District Attorney David Walgren pointedly questioned Dr White, a retired professor and clinical researcher, about the circumstances of Murray's care based on his interview with police two days after Jackson's death.
Dr White told jurors last week that he believes all the evidence in the case shows that Jackson must have taken the propofol when Murray left the room.
"Have you ever administered propofol in someone's bedroom?" Mr Walgren asked. "No I have not," Dr White replied.
"Have you ever heard of someone doing that prior to this case?" the prosecutor asked. "No I have not," Dr White responded.
Later, he said Murray's treatment of Jackson was different from how propofol is supposed to be used - as an anaesthetic used in hospital or clinical settings. "This was an unusual case because the doctor was trying to allow the patient to achieve a sleep state," he said.
