A friend of mine had blunt force trauma to her head and has been in a coma for 50 hours now.  She is around a 5 to 6 on the Glasgow scale; however, tonight her heart rate increased when people were talking to her and her legs moved more. Does this mean shes likely coming out of the coma or is it too hard to tell?  Theyve been running a constant EEG; however, theres no full picture of why shes still in a comatose state.
Blunt head injury leading to coma means hemorrhage in brain MRI must have been done to diagnose location of hemorrhage and soul bone involvement.  Treatment is life supportive and complete rest. Oxygen inhalation iv lifeline, anticoagulant heparin aspirin, constant ECG monitoring, are required. If required she is to be put in ventilator. What you have mentioned are signs of recovery. Hope for the best she will recover completely.
