Since she s been flown to a trauma center I m supposing she had some kind of injury as well and that s what caused the bleeding (facilitated by Xarelto). It s not caused directly by the high blood glucose level, perhaps indirectly she fell due to the high glucose and hit her head (just speculating as you don t give more details on the circumstances). As for the treatment of the bleeding, it depends also on location. At times one could have surgery, but only in selected locations and bleeding types and when an anticoagulant like Xarelto is involved surgeons are very cautious. If she s in a trauma center I suppose she has been evaluated and surgery has not been considered useful. If surgery is not an option then there is no specific treatment for the bleeding, it s mainly a question of supporting therapy, treating complications like high blood glucose, infections, controlling blood pressure, anti-epileptics for seizures and so on according to each patient s individual problems. The bleeding if not causing deadly complications will be gradually absorbed over weeks and the outcome will depend on how big it was and what permanent damages it left behind. Physiotherapy will be needed as well.
