Brief Summary:
The assessment and treatment of Septic Shock (SS) is a thorny issue in current care. Fluid resuscitation is one of the key measures for SS treatment. Current fluid resuscitation is dominated by empirical treatment or early target-directed therapy. The former has a clear goal of recovery, and the latter is complicated to implement and has many complications. It is known that patients with SS due to insufficient tissue perfusion, the distribution of blood flow in the peripheral center to the center, may lead to an increase in the central-peripheral-room temperature difference, suggesting that this index has potential value for direction of fluid resuscitation. This study intends to measure the severity of SS and efficacy of fluid resuscitation by measuring the "central-peripheral-room temperature" gradient of patients as well as comparing temperature gradient with hemodynamic indexes (PICCO) and indexes of ultrasound capacity assessment, providing more convenient indicators for sepsis and fluid resuscitation assessment.

Condition or disease

Detailed Description:
Sepsis remains a great challenge for clinicians. Early and timely fluid resuscitation is the basic measure for the treatment of sepsis. It is important to quickly diagnose the severity of sepsis and evaluate the effects of fluid resuscitation. Existing monitoring methods such as blood pressure, urine volume, blood lactate, central venous oxygen saturation (ScvO2), cardiac output (CO), stroke volume variability (SVV), etc. have certain limitations or invasive disadvantages. Clinically, effective and convenient non-invasive means are needed for monitoring. Present research revealed that microcirculatory dysfunction and tissue hypoperfusion have a very important role in the pathophysiological mechanism of sepsis, and will be associated with severe organ dysfunction, which is closely related to serious adverse prognosis. Importantly, tissue hypoperfusion can cause central and peripheral body temperature changes. Studies have shown that clinical assessment of peripheral skin temperature can identify potential severe organ dysfunction in patients with stable hemodynamics. The latest study found that patients with septic shock have greater central-peripheral body temperature differences than sepsis patients, and the temperature difference between peripheral-room temperature is smaller. That is, the central-peripheral-room temperature gradient changes show a reduction of tissue perfusion, suggesting microcirculatory disorders and organ dysfunction. In addition, the body temperature gradient is simple and non-invasive, and is a bedside indicator that predicts tissue perfusion.
