  Purpose

The purpose of this study is to determine whether application of lower limb remote ischemic preconditioning (RIPC) after determination of brain death improves donor stability, organ quality, organ yield, and early post transplant clinical outcomes.

Neurological death donors will be stratified into standard and extended criteria donors (SCD/ECD) and randomized in a 1:1 fashion to RIPC or No intervention. The primary outcome is the number of organs recovered per donor. Secondary outcomes include donor hemodynamic state, donor organ-specific function parameters, pulsatile perfusion parameters, number of organs transplanted per donor, recipient hospital free survival and delayed graft function of kidneys. The sample size is powered to detect a difference of 0.44 organs recovered.

Further study details as provided by Rutgers, The State University of New Jersey:

Primary Outcome Measures:
  • Number of organs recovered per donor [ Time Frame: At time of organ recovery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number of organs transplanted per donor [ Time Frame: Within 24 hours of organ recovery ] [ Designated as safety issue: No ]
  • Organ Specific Outcomes [ Time Frame: Subjects will be followed from admission to explantation, an average of 4.5 days ] [ Designated as safety issue: No ]
    Changes in the following: Vasopressor usage, serum Lactate, Creatinine clearance, LFTs, P:F ratios, Lung Compliance, Cardiac biomarkers, EF from 2d Echo

  • Pulsatile perfusion parameters [ Time Frame: Up to 24 hours of machine perfusion ] [ Designated as safety issue: No ]
    Perfusate flow and resistance in machine perfused kidneys.

  • Six month hospital free survival of all organ recipients [ Time Frame: 6 months post-transplant ] [ Designated as safety issue: No ]
  • Delayed Graft function (DGF) of Kidney recipients. [ Time Frame: 7 days post-transplant ] [ Designated as safety issue: No ]
    DGF is defined as the need for dialysis within the first week post transplantation.

Arms Assigned Interventions
No Intervention: No RIPC
No intervention will be assigned to this group.
Experimental: RIPC
Remote Ischemic Preconditioning Group
Other: RIPC (Remote Ischemic Preconditioning)
Remote Ischemic Preconditioning (RIPC) by Inflation of Pneumatic Tourniquet. The intervention will consist of tourniquet inflation on the mid-thigh for 5 minutes, followed by a deflation period of 5 minutes for a total of 4 cycles. The intervention will take place at two time points: First, after determination of brain death and consent for organ donation and again upon incision for organ recovery. The second intervention will occur in a manner identical to the first intervention but in the opposite limb.
