The New York clinic where Joan Rivers stopped breathing committed a number of errors, including failing to get her consent for all the procedures performed, according to a federal report released Monday.The report, which did not refer to her by name, found that Yorkville Endoscopy inconsistently documented the amount of the sedative propofol Rivers received before the Aug. 28 procedures, that an ENT doctor without privileges to operate at the clinic performed procedures on Rivers, and that a clinic staffer took a cellphone picture of the comic while she was sedated.The “Fashion Police” star was rushed from Yorkville Endoscopy to Manhattan’s Mount Sinai Hospital after she stopped breathing. While the report said she was resuscitated at the clinic, she did not regain consciousness after arriving at the hospital, and daughter Melissa Rivers had her taken off life support Sept. 4.The Yorkville Endoscopy medical team failed to notice Rivers’ blood-oxygen level dropping below normal in the 15 minutes or so before resuscitation attempts began, the report said.Problems surrounded the clinic’s use of the sedative. According to the report, there was no evidence the clinic weighed Rivers before sedating her, a key step to determining how much sedative a patient should receive. And it’s unclear how much propofol Rivers got. A clinic record showed she received 300 milligrams of the drug, but an anesthesiologist told investigators that the amount had been incorrectly entered and that Rivers really got only 120 milligrams.
