Septic shock, which is caused by the deterioration of sepsis based on microcirculation perfusion of tissues and organs, has been a difficult problem in critical medical care.Effective early fluid resuscitation is important for improving the prognosis of patients.At present, early goal directed therapy based on macroscopic hemodynamics is mostly adopted to guide treatment, but microcirculation indicators are poorly recognized.A large number of studies have found that there is separation between macroscopic hemodynamics and microcirculation indicators, and relying only on macroscopic hemodynamics indicators to guide treatment may cause some adverse consequences and have adverse effects on the prognosis.Microcirculation imaging and automatic vascular analysis have been successfully applied in the diagnosis and treatment of septic shock in adults.Sublingual microcirculation is commonly used to assess microcirculation in critical patients.The value of sublingual microcirculation in the treatment and prognosis of septic shock is discussed.
