Abstract

The aim of this review is to analyze current understanding of the molecular mechanisms of altered sensitivity of the arterial baroreflex and peripheral chemoreflex and their potential association with perioperative complications.
Material and methods. The review includes an analysis of literature data presented in the PubMed database over the past 5 years and some earlier fundamental works.
Results. High risk of perioperative complications is associated with increased sensitivity of the peripheral chemoreflex and decreased sensitivity of the arterial baroreflex. The molecular mechanisms of such a relationship are unclear, but similar changes in reflex sensitivity are observed in chronic diseases of the cardiorespiratory system. Pathobiochemical factors capable of modeling the sensitivity of the chemoreflex and baroreflex include changes in the content of angiotensin II and 1-7, oxidative stress, decreased production of NO and other gasotransmitters, high concentrations of leptin, endothelin and proinflammatory cytokines, etc.
Conclusion. Connection of changes in the sensitivity of the peripheral chemoreflex and arterial baroreflex with a high risk of postoperative complications is associated with markers of cardiometabolic disorders in such patients. This is confirmed by the influence of the angiotensin-aldosterone system, hormones regulating carbohydrate and lipid metabolism, and gasotransmitters.
