Background
Ischaemia–reperfusion injury is inevitable during renal transplantation and can lead to delayed graft function and primary non‐function. Preconditioning, reconditioning and postconditioning with argon and xenon protects against renal ischaemia–reperfusion injury in rodent models. The hypothesis that postconditioning with argon or xenon inhalation would improve graft function in a porcine renal autotransplant model was tested.
Method
Pigs (
Results
Peak plasma creatinine levels were similar between the groups: control 20·8 (16·4–23·1) mg/dl, argon 21·4 (17·1–24·9) mg/dl and xenon 19·4 (17·5–21·0) mg/dl (
Conclusion
Postconditioning with argon or xenon did not improve kidney graft function in this experimental model. Ischaemia–reperfusion injury is inevitable during renal transplantation and can lead to delayed graft function and primary non‐function. Based on mainly small animal experiments, noble gases (argon and xenon) have been proposed to minimize this ischaemia–reperfusion injury and improve outcomes after transplantation.
