Brief summary

The goal of this observational study is to develop and validate a predictive model for prolonged mechanical ventilation (PMV) following acute type A aortic dissection (ATAAD) surgery. The main questions it aims to answer are: 1. To validate the predictive performance of the model for PMV after ATAAD surgery 2. To assess the proportion of PMV among patients undergoing ATAAD surgery 3. To evaluate the ICU length of stay and operative mortality in patients with PMV following ATAAD surgery

Inclusion criteria

* Age ≥18 years; * Diagnosis of acute type A aortic dissection (ATAAD) confirmed by computed tomography angiography and echocardiography; * Patients who underwent aortic surgery requiring cardiopulmonary bypass (CPB), were admitted to the surgical intensive care unit (SICU), and received mechanical ventilation.

Exclusion criteria

* Reintubation; * Intraoperative death or failure to survive beyond 72 hours postoperatively; * Pregnancy; * Severe comorbidities (e.g., lung cancer); * Missing critical outcome data (e.g., short-term mortality, mechanical ventilation duration, reintubation).

Design outcomes

Primary

MeasureTime frameDescription
The predictive performance of the model for prolonged mechanical ventilation (PMV) following acute type A aortic dissection (ATAAD) surgery72 hours after ATAAD surgeryThe predictive performance of PMV following ATAAD surgery includes its discriminative ability and calibration ablility.
The proportion of patients with PMV72 hours after ATAAD surgeryThe proportion of patients with PMV refers to the proportion of patients with PMV among the total included ATAAD postoperative patients. PMV is defined as postoperative mechanical ventilation lasting more than 72 hours

Secondary

MeasureTime frameDescription
ICU length of stay (ICU-LOS)From surgery to discharge or death, whichever came first, assessed up to 6 monthsICU length of stay was defined as the length of time spent in ICU from surgery to discharge or death.
surgery-related mortality30 days after ATAAD surgerysurgery-related mortality encompassed any death occurring during the index hospitalization (even beyond 30 days) or after discharge but before postoperative day 30.
