(Cover) - EN Showbiz - Dr. Conrad Murray's treatment of Michael Jackson seemed like an experiment, the jurors heard in court today.
Dr. Nader Kamangar, a pulmonologist and sleep medicine specialist, resumed his testimony on the stand today.
Jackson died in June 2009 from a Propofol drug overdose. Dr. Murray has been accused of administering a lethal injection of the drug which resulted in the singer's death.
Murray denies the allegations of involuntary manslaughter, claiming that he used Propofol from time to time to help Jackson sleep. Murray's defence also contends that the star ingested too much Propofol while Murray was not around.
Dr. Kamangar, who acts as an advisor for the California Medical Board, said he is familiar with Propofol as he administers the drug to patients on a daily basis.
He stated that the drug must be used with extreme caution as it can be highly "unpredictable", especially when used with other sedatives.
Dr. Kamangar claimed Dr. Murray should "never" have given Jackson any sedatives, as his blood pressure was low and the singer was dehydrated.
Dr. Kamangar testified that Murray's decision to call Jackson's assistant before emergency services was an "unconscionable deviation of care". He stated that Murray exhibited "gross negligence" by withholding health information from emergency personnel and that using Propofol to treat insomnia is inappropriate.
Anaesthesiologist Dr. Steven Shafer, a leading Propofol expert, took to the stand after Dr. Kamangar.
Dr. Shafer was hired by the company who made Propofol 20 years ago. He helped design guidelines for appropriate dosages of the drug. Shafer is expected to assist the prosecution's case by acknowledging that Jackson had too much of the drug in his system and could not have administered that amount himself in his sedated condition.
The court is in recess until Monday due to scheduling conflicts. Dr. Shafer will resume his testimony early next week.
Prosecutors are expected to rest their case after Shafer's testimony. (C) Cover Media
