title: [Remote Ischemic Conditioning - Endogenous Tissue Protection and its Possible Applications in Surgery].
abstract: Tissue perfusion is pivotal to wound healing and tissue regeneration after surgery. Ischemia and reperfusion lead to inflammatory reactions with consecutive tissue damage and necrosis. Multiple conditioning techniques have been described to protect tissue from those damaging mechanisms in the perioperative period. However, most of these fail to meet the requirements of a good therapeutic effect, time and cost efficiency, non-invasiveness and applicability without the need for additional devices or drugs. Remote ischemic conditioning (RIC) is a technique to provide endogenous tissue protection, which fully meets those requirements. Repeated, short cycles of ischemia/reperfusion applied to a circumscribed vascular territory lead to the activation of endogenous signal pathways resulting in increased tolerance to hypoperfusion and limiting the damage caused by reperfusion, even in tissues located far away from the conditioned area. The non-invasive application of the conditioning stimulus requires no more than a pressure cuff, which is placed on the upper arm and is repeatedly inflated to suprasystolic pressures. Different concepts of remote ischemic pre-, peri- and postconditioning enable the usage in both elective and emergency surgical interventions. Based on encouraging experimental studies, the application of RIC has increased in the clinical setting. In addition to studies addressing cardio-, nephro- or neuroprotection there are some initial findings supporting a potential beneficial application in reconstructive microsurgery. This article aims to give an overview of the development, concepts and mechanisms of RIC with a focus on its clinical application in the field of surgery.
