Dr. Alon Steinberg, an expert reviewer for the California Medical Board who reviewed Dr. Conrad Murray's treatment of Michael Jackson, took the stand in Murray's involuntary manslaughter trial Wednesday and detailed numerous ways in which Murray improperly treated Jackson in the time leading up to his death.
In all, Steinberg (pictured) detailed six extreme deviations from standard care on Murray's part -- each of which, according to Steinberg, amount to gross negligence.
Steinberg testified that Murray's negligence included:
--The use of the sedative propofol, when it isn't medically indicated for insomnia
-- Administering propofol in someone's home without the proper equipment, such as an EKG monitor
-- Administering propofol without the proper backup personnel in attendance.
--Administering propofol with inadequate preparation in case of emergency.
--Improper care during Jackson's respiratory arrest. (When he was trying to resuscitate Mr. Jackson, he didn't follow proper protocol, Steinberg testified, adding that performing chest compressions on a patient in respiratory arrest is inexcusable, as it's not necessary in that situation)
--Failure to call 911 in a timely manner. (Noting that Murray first called Jackson's assistant, Michael Amir Williams, when he first noticed that the singer wasn't breathing, Steinberg said, It's basic knowledge, you don't have to be a health-care professional -- when you see someone down, you have to call 911.)
--Failure to maintain proper medical records that could have been handed over to emergency-room personnel when Jackson arrived at UCLA Medical Center.
The deviations in standard care, Steinberg concluded, directly impacted Jackson's death.
If these deviations hadn't happened, Mr. Jackson would be alive, Steinberg told the court.
Steinberg also criticized Murray's decision to leave Jackson's side while he was under the influence of propofol -- which he likened to leaving a baby who's sleeping on your kitchen countertop -- and not keeping the medications properly locked up so that Jackson couldn't get to them, which is what Murray's defense team contends what happened on the day of his death.
The prosecution in the Conrad Murray involuntary manslaughter trial has just three witnesses left to call to the stand before resting its case.
CNN.com reports a sleep expert, a cardiologist and an anesthesiologist are in the prosecution's line-up for Wednesday's court proceedings. The three medical experts are expected to give specific and scientific testimony about Murray's treatment of Michael Jackson leading up to and including his June 25, 2009 death.
The Los Angeles County coroner ruled Jackson died of acute propofol intoxication, and that sedatives were also a factor. Prosecutors contend Murray is criminally liable for Jackson's death because he recklessly administered the propofol, a potent surgical anesthetic drug, and was negligent in properly monitoring Jackson.

Tuesday's courtroom action included the conclusion of the playback of Murray's interview with police two days after Jackson died. During the interview, Murray revealed several details about Jackson's other medical conditions -- including serious problems with his feet and eyes.
Murray also told police about his suspicions that Jackson had been receiving powerful medication from Beverly Hills dermatologist Arnold Klein. Murray said he was told Jackson visited Klein three times a week and returned basically wasted.
Also on Tuesday, jurors heard the testimony of Dr. Christopher Rogers, the medical examiner who conducted the autopsy on Jackson and ruled his death a homicide.
Rogers testified that it was physically possible that Jackson administered a fatal dose of propofol to himself, which the defense claims caused the singer's death.

But Rogers also said it was unlikely that's how events occurred, and said that even if the fatal dose was self-administered, Murray is still responsible for Jackson's death because he provided his client with access to the drug and failed to properly monitor its usage.
Essentially, (Murray) would be estimating how much propofol he would be giving, Rogers said. I think it would be easy under those circumstances for the doctor to estimate wrong and give too much propofol.
CNN.com reports the trial could go to the jury as early as next week. Murray faces up to four years in prison and loss of his medical license if convicted.
