Thank you for your kind replies. Mom has had 10 hours of surgery, 7pm last night 'till 5am this morning. The consultant said she held up well during the surgery. However she is being kept asleep this morning and is on a ventilator. However he said we must still be prepared for worst outcome. To look at her, she is so frail, but to get through 10 hours major surgery she must be very strong. She had veins taken out of her leg to use for a mesenteric bypass. She had the same operation, around 6 years ago but plastic veins were used. These have gone nasty and caused the problem she has now.
I don't know much about these things, but is a ventilator the same thing as life support? I will keep you all posted.
