Remote Ischemia Pre-Conditioning in Patients Undergoing Partial Nephrectomy

December 9, 2015 updated by: University Health Network, Toronto

The Effect of Remote Ischemic Preconditioning in Partial Nephrectomy

Partial Nephrectomy has become the standard treatment in patients with tumours <7cm (T1). Even though this is a nephron sparing surgery, there is still potential for acute kidney injury, due to ischemia during the surgery. Remote Ischemia Preconditioning may prevent acute kidney injury and in turn chronic kidney disease. Remote Ischemia pre-conditioning involves applying a blood pressure cuff and inflating and deflating several times immediately prior to surgery.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Without CellAegis' autoRIC™ Device
patients will have a blood pressure cuff attached to their arm that will not inflate/deflate as in the active group
Device: CellAegis' autoRIC™ Device
Patients in the active group will have the autoRIC device (like a blood pressure cuff) inflated and deflated to a pressure of 200 mmHg in four 5 minute cycles with intervening 5 minutes of reperfusion with the cuff deflated between cycles
Active Comparator: With CellAegis' autoRIC™ Device
Patients will have the CellAegis' autoRIC™ Device attached and it will inflate to 200 mmHg in four 5 minute cycles with intervening 5 minutes of reperfusion with the cuff deflated between cycles (while under general anesthetic)
Device: CellAegis' autoRIC™ Device
Patients in the active group will have the autoRIC device (like a blood pressure cuff) inflated and deflated to a pressure of 200 mmHg in four 5 minute cycles with intervening 5 minutes of reperfusion with the cuff deflated between cycles
