Brief Summary:
Cardiac surgery is associated with cardiac and cerebral injury because of ischemia/reperfusion in approximately one third of cases. Ischemic preconditioning (IPC), have been shown to reduce the extent of myocardial infarction (MI). As another ischemic conditioning, remote ischemic postconditioning, limits MI size in animal models. The purpose of this study is to evaluate the cardiac and cerebral protective effect of remote ischemic postconditioning in children undergoing cardiac surgery, as a single-center, randomized controlled trial.

Condition or disease Intervention/treatment Phase
Ischemia Bypass Complications Procedure: Remote ischemic postconditioning Phase 1

Detailed Description:

Cardiac surgery is associated with Troponin release because of ischemia/reperfusion injury in approximately one third of cases. And I/R injury may also induce cerebral insult, even Postoperative Cognitive Dysfunction (POCD).Transient sublethal episodes of ischemia before a prolonged ischemia/reperfusion injury, known as ischemic preconditioning (IPC), have been shown to reduce the extent of myocardial infarction (MI).And remote ischemic postconditioning(RIPoC), as another ischemic condition, limits MI size in animal models.

However, there are limited outcome to demonstrate protection from RIPoC during cardiac surgery. The purpose of this study is to investigate the cardiac and cerebral protective effect of remote ischemic postconditioning , as a single-center, randomized controlled trial.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 65 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Randomized Control Trial of Effect of Remote Ischemic Postconditioning on Children Undergoing Cardiac Surgery
Study Start Date : August 2011
Actual Primary Completion Date : October 2012
Actual Study Completion Date : October 2012

Arm Intervention/treatment
Experimental: Remote ischemic postconditioning
At the time of reperfusion, remote ischaemic postconditioning will be induced by inflating a cuff around leg to 100 mmHg for 5 mins followed by 5 mins of reperfusion. This cycle will be repeated 3 times.
Procedure: Remote ischemic postconditioning
At the time of reperfusion, remote ischaemic postconditioning will be induced by inflating a cuff around leg to 100 mmHg for 5 mins followed by 5 mins of reperfusion. This cycle will be repeated 3 times.
Other Name: Limb ischemic postconditioning

No Intervention: control
A blood cuff was around leg without inflation or deflation.



Primary Outcome Measures :
  1. cTnI,CK-MB concentration [ Time Frame: 24h after Remote Ischemic Postconditioning ]
    The primary outcome is assessing whether cTnI or CK-MB concentration reduce at 24 hours after remote ischemic postconditioning.


Secondary Outcome Measures :
  1. NSE,S100β concentration [ Time Frame: 24 hours after Remote Ischemic Postconditioning ]
    The secondary outcome is assessing whether NSE or S100-β concentration reduce at 24 hours after remote ischemic postcondioning.
