He is in the hospital, and we are hopeful that he will pull through.  Poor Dad has had it very rough; his fingers were literally rotting off, he couldn't eat, and had lost a great deal of weight. 

In my condition, I wasn't much help while we were down there, other than to encourage him to go to the hospital.  My sister Kay, who is a RN who worked at Duke University Medical Center, drove down from Corpus Christi right after we left to come back home.  Kay knows what Dad needs, and let the medical staff know it.  (She had been a DI in the Army.  Believe me, her prior military experience serves her well.)

Kay has been wonderful for Dad and has hopefully gotten him the help he needs....including simple things, that the doctor and nurses should have done back when he first started having these problems (like lidocaine gel for his poor fingers).  She has a very take-charge personality, which is really a blessing in a case like this.  With her help, I think my dad has a much better chance of getting through this.

I don't know how to thank her for her help, I don't know how to tell her how much I appreciate her.  A card seems to be too small, but that is what I will be sending.  How do you thank someone for saving your father's life?
