OAKLAND, Calif. -- A 13-year-old girl is brain dead and on life support following what appeared to be a routine surgery to have her tonsils removed, according to KGO-TV.
According to the report, Jehi McMath, 13, and her mother went to Oakland Children's Hospital on Dec. 9.
The mother of the young girl, Nailah Winkfield, said Jehi was nervous at first but that she reassured her the surgery was to "make [her] better."
The surgery was being performed because doctors believed it would help the girl with her sleep apnea.
Following the surgery, the girl had complications in recovery.
"My daughter had actual clots sliding out of her mouth and they gave me a cup and said, 'here catch them with the cup so we can measure them,'" Winkfield said.
The girl later went into cardiac arrest and momentarily died before being revived and put on life support, according to her mother.
The family is demanding the hospital conduct an investigation to find out how Jehi was left in this condition following a seemingly routine surgery.
The family has said they do not want to take the young girl off life support.
