  Purpose

Major abdominal surgeries are associated with perioperative cardiac morbidity of up to 10%.

Ischemic preconditioning may have a protective effect. The purpose of this study is to find out remote ischemic conditioning by inflating a blood pressure cuff on the arm will have a protective effect.


Condition Intervention Phase
Perioperative/Postoperative Complications Procedure: Remote Ischemic Pre-conditioning Procedure: Control Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Remote Ischemic Preconditioning Before Abdominal Surgery and the Prevalence of Perioperative Complications

Further study details as provided by Lawson Health Research Institute:

Primary Outcome Measures:
  • Cardiovascular Events: incidence of MI, TIA/stroke, death in both groups [ Time Frame: One week ]

Secondary Outcome Measures:
  • Renal function deterioration in the first week after surgery [ Time Frame: One week ]
    Baseline Creatinine levels will be compared to the highest creatinine levels noted in the first 7 days of hospitalization


Estimated Enrollment: 440
Study Start Date: June 2010
Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
