Brief Summary

The morbidity rate of Stanford A type Acute Aortic Dissection(AAD) has been increasing, about 5-10/100,000\* per year. Emergency surgery has been the main treatment for Acute Aortic Dissection, however perioperative mortality rate can be as high as 15\~30%. Acute lung injury (ALI) is one of the main complications that happen during the perioperative period, which by itself covers 30%-50% of the overall mortality rate. Both domestic and foreign countries lack researches on risk factors, pathogenesis, disease progression and outcome of ALI, which happen during the perioperative period of Acute Aortic Dissection patients. This topic study follow projects in the preoperative of Acute Aortic Dissection'surgery

  1. 1.hemodynamic changes (aortic dissection resulting in acute aortic regurgitation, cardiac tamponade and proximal high blood pressure)
  2. 2.ischemia - reperfusion injury of aortic dissection distal organ
  3. 3.Aortic intima-media exposure cause coagulation / fibrinolytic system function disorder
  4. 4.systemic inflammatory response syndrome; use relevant clinical radiographic parameters, indicators of respiratory mechanics (oxygenation index and lung injury index) and biochemical indicators.

Outcome Measures

Primary Outcomes (1)

  • perioperative outcome and improve of ALI

    indicators * chest imaging (preoperative, 12 hours after ICU); * arterial blood gases and alveolar-arterial oxygen difference (before surgery, and immediately after induction of anesthesia, before surgery ends and 12 hours after ICU); * respiratory mechanics (immediately after induction of anesthesia, before the end of surgery and 12 hours after ICU); including peak airway pressure, plateau pressure, dynamic and static compliance and so on.

    Period from 48 hours before surgery to 12 hours after ICU

Secondary Outcomes (1)

  • systemic inflammatory response

    Period from 48 hours before surgery to 12 hours after ICU
