Correction: Risk factors of prolonged mechanical ventilation after acute type A aortic dissection surgery: a single-center retrospective study

Key Result

In this single-center retrospective study, risk factors for prolonged mechanical ventilation after acute type A aortic dissection surgery were investigated but exact effect sizes were not reported.

Key Points

To identify risk factors associated with prolonged mechanical ventilation following acute type A aortic dissection surgery.
Retrospective analysis of patient records from a single center
Identification of postoperative complications and demographic variables
Assessment of mechanical ventilation duration in relation to various risk factors
Certain demographic characteristics were identified as significant predictors of prolonged mechanical ventilation
Postoperative complications were associated with extended intubation periods
The study provides insights into improving patient management and outcomes.

Study Design

Type

Observational

Multicenter

Structured PICO

Population

Consecutive patients aged >18 years who underwent surgical treatment for acute type A aortic dissection (ATAAD) suspected by aortic enhanced CT within 14 days of disease onset, treated at a single center between January 2016 and December 2021. Excluded: traumatic aortic dissection, pregnancy, onset >14 days prior to admission, and intraoperative death.

Intervention

Acute type A aortic dissection (ATAAD) surgery

Outcome

Delayed extubation (total duration of mechanical ventilation exceeding 48 h after surgery)

This correction article updates the funding statement, study population inclusion/exclusion criteria, and data definitions for a retrospective cohort study evaluating risk factors for delayed extubation after ATAAD surgery.

Limitations

Single-center study limits generalizability
Retrospective design prone to bias
Exact sample size and quantitative results not reported in correction notice
No randomized control group or intervention compared
