[Remote Ischemic Conditioning - Endogenous Tissue Protection and its Possible Applications in Surgery]

Area of Science:

• Surgical innovation
• Vascular biology
• Regenerative medicine

Background:

• Tissue perfusion is critical for wound healing and post-surgical regeneration.
• Ischemia and reperfusion injury cause significant tissue damage and necrosis.
• Existing conditioning techniques often lack therapeutic efficacy, cost-efficiency, or non-invasiveness.

Purpose of the Study:

• To provide an overview of remote ischemic conditioning (RIC).
• To discuss the development, concepts, and mechanisms of RIC.
• To focus on the clinical applications of RIC in surgery.

Main Methods:

• RIC involves applying short cycles of ischemia/reperfusion to a remote vascular territory.
• The stimulus is delivered non-invasively using a pressure cuff on the upper arm.
• This triggers endogenous protective pathways, enhancing tissue tolerance.

Main Results:

• RIC activates endogenous signaling pathways for tissue protection.
• It increases tolerance to hypoperfusion and limits reperfusion injury.
• RIC is applicable in various surgical settings (pre-, peri-, postconditioning).

Conclusions:

• RIC is a promising, non-invasive technique for endogenous tissue protection in surgery.
• It offers a therapeutic approach that meets requirements for efficacy, cost, and applicability.
• Emerging evidence suggests potential benefits in reconstructive microsurgery and other surgical fields.
