SURGERY AND TRANSPLANTATION 
Dr. Hardy: We've been using 5 milligrams 
per kilogram per day and decrease gradually 
over a two-month period. 
Chairman: Do you think we will have to 
transplant one or two lungs in human patients ? 
Dr. Hardy: I'll have to refer that question 
back to you. I recently read a manuscript of 
yours in which you suggest that experience with 
your patient showed we will not necessarily 
have to transplant both lungs. I myself don't 
believe anybody has proven that both lungs 
have to be transplanted, and I think we will 
continue to transplant one lung in human be- 
ings as long as we consider it reasonable to do 
so. 
Let me point out that we can either transplant 
both lungs with the heart "en bloc" or trans- 
plant one lung and then the other lung. Dr. 
Haglin had a case in Minnesota in which he 
transplanted one lung into a patient and had 
the other one in the refrigerator; later in the 
day when the patient wasn't going to make it 
on one lung, Dr. Haglund transplanted the re- 
maining lung on the other side, leaving the 
heart unmolested.
