Claims were made that the same drug that was blamed for the death of Michael Jackson, the King of Pop, was received by the Queen of Comedy, Joan Rivers.

According to The Guardian Liberty Voice, during sedation for an endoscopic procedure, she slipped into a coma and didn't come out of it. As an anaesthetic, she was administered propofol that is used for simple medical procedures and is considered the cause of death for Michael Jackson.

Hospital staff confirmed that propofol is a drug used for endoscopy and colonoscopy procedures. The drug was even referred to as the Michael Jackson's drug.

The medical personnel conducting the procedure hadn't realized until the surgery was almost ending that Rivers' oxygen level was decreasing and though it was unclear what led to her having issues with breathing, it could be propofol. Propofol has a tendency of creating an error between respiratory arrest and sedation.

The clinic has admitted that if the drug wasn't given correctly, it could cause death in the patient. They have also said that they had followed the proper and legal protocols that need to be taken into consideration before administering the drug.

Her death could have also been due to an anaesthetic or a complication of the procedures. Attempts at stabilizing Rivers, including trying to place a tube down her throat to get her to breathe again, remained unsuccessful.

Yorkville Endoscopy. where Joan's procedure took place, is currently being investigated by the Department of Health in New York. The staff claim that under the effect of anaesthesia, Rivers had stopped breathing. Paramedics were called who performed CPR after in which she started breathing, though she was still considered to be in bad shape.

An ear, nose and throat specialist was present during the procedure despite him not being authorized to practice medicine at the clinic. He was invited by Rivers' gastroenterologist. Before and after the gastroenterologist performed the endoscopy, the ENT specialist examined Rivers' voice box.

The two, ENT as well as the gastroenterologist, have not been accused of any wrongdoing though the ENT was unauthorized to be present at the clinic.
