Objective: To investigate the effect of administration of vitamin C during kidney transplantation surgery on postoperative renal function.
Study design: Triple blind randomized clinical trial.
Inclusion criteria: patients who are undergoing kidney transplantation.
Exclusion criteria: drug sensitivity; cardiomyopathy; chronic obstructive pulmonary disease (COPD) and respiratory diseases; intraoperative hypotension; inotrope requirement during the surgery.
Intervention: The 64 kidney recipients were divided into two groups (A & B). The patients in group “A” received infusion of 100 mg / kg (total volume with normal saline 50 cc) within 6 hours, and patients in group “B” received infusion of normal saline(50 cc) within 6 hours. Venous blood sampling was done for all patients in 3 stages (at the beginning of the operation, 1 and 2 hours after declamping of renal artery) to check MDA (Malondealdehyde) and TAC (total antioxidant status) as markers of free oxygen radicals activity and body oxidant status. Also graft function was monitored by measurement of BUN, creatinine, GFR and need for hemodialysis on the first 5 days and also 1 month after transplantation.

Other design features
In order to randomization, by using the site www.randomization.com twenty-frequency (permutation) binary of A and B were made then draw the group receiving vitamin C (A or B) is determined. To assign patients to one of the two groups two patients who are supposed to use a donor kidneys become a pair. Of the individual pairs that his/her last name comes first in alphabetical view is selected as the upper part of the B-A block.if the alphabetical view of the initial word of the family name was similar then we will use the alphabetical order of the first name and if similar initial word of the father name and at least national code will be used. After obtaining consent patients without the knowledge that which of the syringe is vitamin C or saline divided into two groups of case and control. (Syringes with volume of 50 cc and same shape. And a person who is unaware of the study prepares Syringes with labeled A, B on which they put at the disposal of researchers.)
