[The applications and challenges of combined monitoring of macro/micro-circulation and mitochondrial homeostasis in early warning of perioperative organ injury].

ABSTRACT

Perioperative organ injury is a leading risk factor for mortality in surgical patients. Given the current limitations in the timeliness and accuracy of markers for perioperative organ injury, this article proposes a comprehensive early-warning assessment system that jointly monitors the macro-circulation, micro-circulation, and mitochondrial homeostasis. Macro-circulation monitoring allows for real-time evaluation of key indicators such as blood pressure and cardiac output, while micro-circulation monitoring aids in assessing the status of microvascular perfusion. Monitoring of mitochondrial homeostasis provides timely insights into cellular energy metabolism. These three facets are interconnected and collectively determine the balance between tissue oxygenation and energy supply and demand. This article will elucidate commonly used monitoring methods and clinically valuable assessment models within this system, offering theoretical and technical guidance to deepen our understanding of the pathological processes of perioperative organ injury, enhance surgical safety and success rates, and improve patient prognosis and quality of life.
