NCT01316497

Brief Summary

The purpose of this study was to investigate if repeated inflation of a blood pressure cuff applied around one leg causing mild ischemia ("remote ischemic preconditioning") could protect children operated for congenital heart disease from developing acute kidney injury.

Study Arms (2)

Remote ischemic preconditioning (RIPC)

EXPERIMENTAL

See intervention description

Procedure: Remote ischemic preconditioning (RIPC)

Control

PLACEBO COMPARATOR
Procedure: Control

Interventions

RIPC was performed by applying a blood pressure cuff around the child's leg. The cuff was inflated to 40 mmHg above the systolic pressure in 4 cycles of 5 minutes. Every cycle of ischemia was followed by 5 minutes of reperfusion. The first RIPC cycle started after anesthesia induction when invasive arterial blood pressure was monitored. Appropriate cuff size was used choosing between four sizes. For reproducibility RIPC was performed on the right leg with only a few exceptions, when the leg was used for invasive catheters.

Remote ischemic preconditioning (RIPC)
ControlPROCEDURE

The cuff was applied on the leg without inflation in the control group.
