Hello and hope you are doing well.
Understand your predicament. But it is difficult to predict the prognosis. With all the complications mentioned, it appears that her vitals are stable. With severe brain damage, she is likely to have residual effects. If she does not have any other co morbid conditions like diabetes, she will have a better prognosis. Her treating doctors will be able to guide you better as to her prognosis. Please discuss with them. Wish her luck. Regards.
