Brief Summary

Aortic dissection (AD) is one of the most dangerous cardiovascular emergencies, with rapid onset, rapid progression, high fatality rate, and a variety of life-threatening complications. Acute lung injury (ALI) caused by AD is an important cause of many adverse outcomes. Studies have confirmed that 34.9% to 53.8% of AAD patients have ALI before surgery, and Impaired preoperative lung function may lead to worse oxygenation after AD surgery. The pathophysiological mechanism of AD-induced ALI is complex. A variety of preoperative and intraoperative risk factors can induce or aggravate ALI, such as ischemia-reperfusion injury, deep hypothermic circulatory arrest, and inflammatory reactions. At present, the clinical use of improved surgery, cardiopulmonary bypass perfusion, early anti-inflammatory treatment, and protective lung ventilation can reduce and improve perioperative ALI to a certain extent, but it is still not ideal. In recent years, inhibition of neutrophil activation and aggregation, and reduction of neutrophil elastase activity as targets for the treatment of inflammatory injury have also become an important clinical treatment measure, in order to further reduce the body's inflammatory response to improve and alleviate ALI. Sivelestat sodium, as a neutrophil elastase inhibitor, is the only approved therapeutic drug for ALI/ acute respiratory distress syndrome (ARDS) in the world. It is precisely by reducing the inflammatory infiltration of neutrophils and inhibiting neutrophil elastase activity, thereby exerting a certain protective effect on the lungs. The study takes patients with AD surgery as the research object. On the basis of not terminating and changing the original treatment plans, sivelestat sodium was added in the perioperative period to observe the incidence, and severity of ALI/ARDS in the perioperative period. It aims to explore the efficacy and safety of sivelestat sodium in the treatment of pulmonary insufficiency after AD arch surgery under hypothermic circulatory arrest.

Study Arms (2)

sivelestat sodium on the basis of the original treatment

EXPERIMENTAL

In the perioperative period, sivelestat sodium was added, and on the basis of not terminating and changing the original treatment plans.

Drug: Sivelestat sodium

the original treatment

NO INTERVENTION

Only accept the original clinical diagnosis and treatment and clinical management.

Interventions

After dissolving sivelestat sodium with 0.9% sodium chloride injection, dilute the 1-day dose (4.8 mg/kg) with 50 mL of 0.9% sodium chloride injection and continue intravenously at a rate of 0.2 mg/kg/h for administration. The start time of administration was after induction of anesthesia, and at the same time, the extracorporeal circulation circuit is prefilled with 100 mg. The end time is 48 hours after admission to the ICU.
