Overview
Acute kidney injury is a well-recognized complication in critically ill patients. Up to date there is no clinically established method to reduce the incidence or the severity of acute kidney injury.
Remote ischemic preconditioning (RIPC) will be induced by three cycles of upper limb ischemia.
The aim of the study is to reduce the incidence of AKI by implementing remote ischemic preconditioning (identified by the urinary biomarkers tissue inhibitor of metalloproteinases-2 (TIMP-2) and insulin-like growth factor-binding protein 7(IGFBP7)
Description
Acute kidney injury (AKI) is a common complication in critically ill patients with sepsis. To date, there is no pharmacological option to treat or prevent AKI.
Ischemic conditioning is an innate tissue adaptation elicited by ischemia that mediates local and remote organ protection against subsequent exposure to the same or other injury.
The aim of this trial is to evaluate the effects of remote ischemic conditioning in critically ill patients on acute kidney injury.
