“…In addition, a recent study presented different results, where Magnin et al found no effect of blood donation on sublingual microcirculatory parameters in dogs (24). This phenomenon was most likely due to changes in microcirculation caused by insufficient blood collection, and the insufficient sample size and heterogeneity of animal species were also possible causes (24). Holley et al measured the PPV and other indices in shock patients in a prospective trial to assess the relationship between microcirculatory parameters and patient prognosis within 24 h and found that microcirculatory indices in the early stages did not predict patients’ clinical outcomes (25).…”

“…Domizi et al conducted a retrospective study of 28 critically ill patients with acute respiratory illness, injuries due to trauma, and general medical/surgical problems and found that patients with high Sequential Organ Failure Assessment scores on day 4 had significantly lower TVD and PVD values on days 1 and 2; therefore, sublingual microcirculatory parameters could predict tissue perfusion in critically ill patients (23).

Hemorrhagic shock (HS) is a common complication after traumatic injury. Early identification of HS can reduce patients’ risk of death. Currently, the identification of HS relies on macrocirculation indicators such as systolic blood pressure and heart rate, which are easily affected by the body's compensatory functions. Recently, the independence of the body's overall macrocirculation from microcirculation has been demonstrated, and microcirculation indicators have been widely used in the evaluation of HS. In this study, we reviewed the progress of research in the literature on the use of microcirculation metrics to monitor shock. We analyzed the strengths and weaknesses of each metric and found that microcirculation monitoring could not only indicate changes in tissue perfusion before changes in macrocirculation occurred but also correct tissue perfusion and cell oxygenation after the macrocirculation index returned to normal following fluid resuscitation, which is conducive to the early prediction and prognosis of HS. However, microcirculation monitoring is greatly affected by individual differences and environmental factors. Therefore, the current limitations of microcirculation assessments mean that they should be incorporated as part of an overall assessment of HS patients. Future research should explore how to better combine microcirculation and macrocirculation monitoring for the early identification and prognosis of HS patients.
