Does it matter which solution is used to store harvested grafts for during HT?
Hi, I am 36 years old male and going for HT in March, my Dr in London just confirmed me he uses Chilled Saline solution to store harvested grafts while he is doing the incision. Please can you advise how effective is the saline solution for this purpose? Is there a huge difference in yield when compared saline with other solutions to store the grafts?

Last thing, is it better to spray ATP after the HT? I see lot of doctors on different forms suggesting that, but by doctor do not provide ATP after HT.
