AP source: Michael Jackson doc gave sedatives before death

LOS ANGELES (AP) — Hours before Michael Jackson’s death, his doctor administered multiple sedatives along with a powerful anesthetic the pop star used to sleep, according to a law enforcement official.

It’s a safe combination if done properly; potentially lethal if not.

The official said the type of sedatives Dr. Conrad Murray gave Jackson were benzodiazepines, often used to calm patients before surgery.

Murray told investigators the doses were within normal medical guidelines, said the official, who spoke to The Associated Press on condition of anonymity because the investigation is ongoing.

Even at acceptable levels, benzodiazepines can intensify how the anesthetic propofol depresses breathing, so strict monitoring and careful dosing is required. The balance can be tricky, a slip-up disastrous.
