Anesthesia

I don't know if I am posting in the right place but I need your help.
Two years ago, it was diagnosed that my mother was suffering from an ulcer in her stomach. She did not pay any attention to it. Last week when she went on her appointment, our doctor told her that her health has worsened since he has got that ulcer in his stomach. She has been hospitalized the same day. The doctor has said that she will be put on diprivan anesthesia so that she doesn't feel any pain during the operation. Yesterday she was operated and till now she is still unconscious. I read about some side effects of diprivan on the net, http://www.drugdelivery.ca/s3445-s-DIPRIVAN.aspx and I am very worried for her.
