Purpose
Remote Ischemic Preconditioning (RIPC) is a treatment that may be associated with improved outcomes after cardiac surgery. It can be elicited noninvasively by using a tourniquet to elicit transient ischemia over a lower extremity. It is thought to promote anti-inflammatory and cell survival pathways, and thus protect remote organs against future ischemic injury. We hypothesize that compared to sham treatment, RIPC will be associated with decreased post-operative acute kidney, myocardial, and lung injury.

- Incidence of acute kidney injury (AKI) [ Time Frame: 72 hours ] [ Designated as safety issue: Yes ]Serum creatinine (SCr) will be measured at baseline, then on post-operative days 1, 2, and 3.
- Incidence of acute myocardial injury [ Time Frame: 48 hours ] [ Designated as safety issue: Yes ]Troponin-I will be measured at baseline, then 6, 12, 24, and 48 hours post-operative.
- Incidence of acute lung injury [ Time Frame: 72 hours ] [ Designated as safety issue: Yes ]Days on mechanical ventilation, readiness for extubation.
- Hospitalization [ Time Frame: Duration of post-operative hospitalization ] [ Designated as safety issue: Yes ]Number of post-operative days in cardiac intensive care unit (CICU) and hospital.
- Mortality [ Time Frame: Duration of hospitalization ] [ Designated as safety issue: Yes ]
- Biomarkers for AKI [ Time Frame: 72 hours ] [ Designated as safety issue: No ]Serum and urine will be collected for biomarker discovery.
- Inflammation [ Time Frame: 72 hours ] [ Designated as safety issue: No ]Cytokines will be measured at baseline until 72 hours post-operative.

| Experimental: Remote Ischemic Preconditioning (RIPC) |
Procedure: RIPC
RIPC will be elicited in the operating room (OR) after anesthesia induction and before start of surgery. After placement of an arterial line, a tourniquet will be placed over a lower extremity. It will be inflated to 15 mmHg above systolic blood pressure for 5 minutes, and then deflated for 5 minutes. This cycle of inflation-deflation will be repeated another 3 times before surgery.
|
| Sham Comparator: Control |
Procedure: Control
In OR, after induction of general anesthesia and arterial line placement, a deflated tourniquet will be placed over the lower extremity for 40 minutes.

Detailed Description:
In children undergoing cardiac surgery and cardiopulmonary bypass (CPB), our primary aims are to determine whether RPC is associated with: 1) decreased AKI and 2) decreased acute myocardial injury. Secondary aims include investigating the effects of RPC on post-procedure: 1)acute lung injury and 2) morbidity/mortality.
