The Influence of Remote Ischemic Preconditioning on Acute Kidney Injury After Cardiac Surgery

This study is enrolling participants by invitation only.

Maine Medical Center Research Institute

NCT00821522
First received: January 9, 2009
Last updated: July 21, 2010
Last verified: April 2010
  Purpose

Acute kidney injury is associated with cardiopulmonary bypass during heart surgery and its pathogenesis is similar to that of ischemia-reperfusion injury. Remote ischemic preconditioning attenuates myocardial ischemia-reperfusion injury in patients undergoing coronary bypass surgery. The investigators hypothesize that such preconditioning reduces the incidence of acute kidney injury associated with cardiopulmonary bypass.

Further study details as provided by Maine Medical Center Research Institute:

Primary Outcome Measures:
  • Incidence of acute kidney injury, after surgery, as defined by elevation in serum creatinine greater than or equal to 0.3 mg/dl. [ Time Frame: 48 hours after surgery. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Oliguria. [ Time Frame: 12 hours after surgery. ] [ Designated as safety issue: No ]
  • Incidence of acute kidney injury as defined by post-operative elevation in NGAL. [ Time Frame: 3 hours after cardiopulmonary bypass. ] [ Designated as safety issue: No ]
