Several studies have highlighted the cardioprotective effects of acute normovolemic hemodilution during cardiac surgery. The aim of our study is to show that an increase in endogenous erythropoietin (EPO) might explain the cardioprotective effects of acute normovolemic hemodilution against ischemia-reperfusion phenomena.

Condition Intervention
Cardiac Surgery
Procedure: acute normovolemic hemodilution

Study Type: Interventional
Study Design: Allocation: Randomized

Estimated Enrollment: 40
Study Start Date: March 2009

Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: placebo, hemodilution Procedure: acute normovolemic hemodilution

Detailed Description:

The major physiologic function of EPO is thought to be the induction of erythropoiesis. However, a growing body of evidence indicates that EPO has tissue-protective effects and prevents tissue damage during ischemia. In an ex vivo proof-of-concept, protective effects of EPO have been shown in human myocardium.

Several studies have demonstrated that acute normovolemic hemodilution before aortic cross clamping decreases perioperative myocardial damage. We hypothesized that the onset of acute anemia increases the endogenous EPO concentration, which explains the cardioprotective effects of acute normovolemic hemodilution.
