Predictive Value of Sublingual Microcirculation and Peripheral Tissue Oxygen Monitoring

Predictive Value of Sublingual Microcirculation and Peripheral Tissue Oxygen Monitoring in Sepsis Patients With Successful Fluid Resuscitation

Change and predictive Value of Sublingual Microcirculation and Peripheral Tissue Oxygen Monitoring in Sepsis Patients With Successful Fluid Resuscitation

Fluid therapy for sepsis patients has always been a research hotspot. Early studies suggest that early goal-directed therapy (EGDT) can reduce mortality in patients with sepsis and septic shock, which is included in the guidelines. However, recent studies suggest that EGDT does not reduce mortality. This may be related to the fact that EGDT only pays attention to systemic circulation and neglects microcirculation.

In the past few decades, arterial blood pressure, blood lactic acid and other circulatory indicators have been the target of septic shock treatment, but normal systemic circulation does not mean normal tissue perfusion. Obstacles to tissue perfusion, oxygenation and microcirculation may still exist. At the same time, compared with systemic hemodynamic parameters, microcirculation parameters may play a stronger role in predicting the prognosis of sepsis patients. It is believed that the ideal goal of resuscitation therapy for sepsis should be based on whether microcirculation function has been restored or not.

Objective:to observe the success rate of microcirculation imaging and oxygen saturation of peripheral tissues in sepsis patients under the guidance of current guidelines and procedures. At the same time, we compared the predictive value of microcirculation indicators to the prognosis of septic shock patients.
