A Pilot Study of Sivelestat Sodium to Shorten Mechanical Ventilation in Acute Aortic Dissection

Acute Aortic Dissection Clinical Trial

Official title:
A Pilot Study of Perioperative Application of Sivelestat Sodium in Acute Type A Aortic Dissection Patients With Preoperative Moderate to Severe Hypoxemia to Shorten the Duration of Postoperative Invasive Mechanical Ventilation

Clinical Trial Summary

This is A prospective, randomized, placebo-controlled, reestimable adaptive clinical study to evaluate the efficacy and safety of perioperative application of sivelestat sodium to shorten the duration of postoperative invasive mechanical ventilation in acute type A aortic dissection patients with preoperative moderate and severe hypoxemia (PaO2/FiO2≤200mmHg).

Clinical Trial Description

In recent years, sivelestat sodium therapy has been used to treat and prevent CPB-associated lung injury with good results. Morimoto K et al., randomized control of a small sample size, demonstrated that sivelestat sodium improves respiratory function in patients with severe respiratory failure after hypothermia thoracic aortic surgery. A retrospective study by Morimoto N et al. confirmed that prophylactic application of sivelestat sodium at the beginning of CPB could improve postoperative respiratory function and shorten the duration of mechanical ventilation in patients with hypothermic circulatory arrest. At present, there is a lack of reliable RCTS to confirm that the intraoperative application of sivelestat sodium can effectively treat preoperative acute lung injury, improve CPB-related lung injury, and reduce the incidence of postoperative acute lung injury. Therefore, the objective of this study was to design A randomized controlled study to evaluate the clinical efficacy and safety of intraoperative use of sivelestat sodium to shorten the duration of postoperative invasive mechanical ventilation in acute type A aortic dissection patients with preoperative moderate to severe hypoxemia. The purpose of this preliminary clinical trial is to provide theoretical basis for sample size calculation of randomized controlled trials, and to evaluate the scientific nature and feasibility of randomized controlled trials. ;
