Arms Assigned Interventions
No Intervention: control
patients had a deflated cuff placed on the left lower limb for 30 min
Experimental: donor
Donors receive remote ischaemic preconditioning after anaesthesia induction and before surgery started
Device: remote ischaemic preconditioning
Remote ischaemic preconditioning consisted of three 5-min cycles of left lower limb ischaemia, which was induced by an automated cuff-inflator placed on the left lower limb and inflated to 300 mm Hg, with an intervening 5 min of reperfusion during which the cuff was deflated.
Experimental: recipient
recipients receive remote ischaemic preconditioning after anaesthesia induction and before surgery started
Device: remote ischaemic preconditioning
Remote ischaemic preconditioning consisted of three 5-min cycles of left lower limb ischaemia, which was induced by an automated cuff-inflator placed on the left lower limb and inflated to 300 mm Hg, with an intervening 5 min of reperfusion during which the cuff was deflated.

Detailed Description:

Ischemia reperfusion injury (IRI) induced renal failure after kidney transplantation is a common clinical problem associated with a high morbidity and mortality. To reduce the adverse effects of IRI after organ transplantation various strategies aimed at the different pathophysiological processes of IRI have been investigated. Remote ischemic preconditioning (RIPC) is one such strategy where brief IRI of one organ protects other organs from sustained IRI. Many studies have shown that RIPC protects heart, muscle flaps, stomach, liver, lungs, and kidneys from IRI. RIPC of the limb with a tourniquet is a safe and convenient method of preconditioning organs against IRI. However, the efficacy of RIPC in patients undergoing living donor kidney transplantation need to be established and mechanism of early and late RIPC, such as whether the donor should undergo remote preconditioning or the recipient, need to be investigated.
