Protective Effect of Ulinastatin and Thymosin α1 Against Negative Immune Dysregulation and Organ Dysfunction After Acute Aortic Dissection Surgery (PANDA XI)

Systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) are the major causes of death in patients with acute aortic syndrome (AAS). Therefore, the prevention of SIRS and MODS is of great clinical value, and immunomodulatory therapy with thymosin alpha

1 in addition to antiinflammatory treatment may be beneficial. This study was designed to test the hypothesis that the administration of Ulinastatin and Thymosin α1 during the acute phase of AAS will result in a reduced incidence of SIRS and MODS.

Inclusion Criteria:

• Patients with acute aortic syndrome confirmed clinically and radiologically and planning to undergo emergency surgery were enrolled.
• The patients' age between 18 ~90 years old.
• Agree to participate in the study and sign the informed consent.

Exclusion Criteria:

• Patients allergic to Thymosin α1 or Ulinastatin;
• Lactating women and pregnant women;
