Date are presented as mean ± SD or numbers. Group I: living kidney donor patients under open nephrectomy received high-flow oxygen; Group II: living kidney donor patients under open nephrectomy received air. NTAD: need to additional diuretic; AO: after operation; NTH: need to hemodialysis, FENa₂: fractional excretion of sodium at posttransplant day 2; CrCL₁₀: creatinine clearance throughout posttransplant day 1 to 10; BUN₁₀: blood urea nitrogen throughout posttransplant day 1 to 10; ATN: acute tubular necrosis; MI: myocardial infarction. *𝑃<.05 versus Group II. ^α𝑃=.07.
