Hemispherectomy

I am the nanny of a 9 year old little boy who had a anotomical hemispherectomy just over 3 weeks ago.  He has been very sick since the surgery.  His temp goes up to 103 or higher every day.  He can hardly talk.  He is in constant pain on the right side of his body, which is paralized.  He can't walk.  I just feel so horrible for him that his life has been reduced to this.  He was have 15-100 grand mal seizures a day before the surgery and was in status epilepticus when the doctors finally said we had to do the surgery now or we would lose him.  He's had a VNS, a temporal lobectomy and was on 16 different meds (phelbatol, phenobarb., ativan, diastat, trileptol, lamectol, prednisone,etc.)  After the surgery he is seizure free.  I am just wondering if anyone has any knowledge of what to expect.  None of the Doctors or nurses can tell us anything.  Will he walk?  Talk?  Re-gain vision?  Will he be Spenser again? Anyone have any experiance in this?  Thanks
