Tameka Foster entered a hospital in Sao Paolo, Brazil, last Friday for a liposuction procedure. She suffered a cardiac arrest while getting anesthetized for the surgery, "but was revived in less than a minute by heart massage," Ellen Dastry, a spokeswoman for plastic surgeon Silvio Sterman, told the Associated Press. Foster was then induced into a coma and taken to the intensive-care unit — protocol Dastry said is "absolutely normal" and meant to "avoid unnecessary complications."
Later the same day, Foster was moved to a reportedly better-equipped hospital in Sao Paolo, where she is recovering. No further details have been disclosed.
