Risk Factors for Atelectasis Following Right Subaxillary Small‐Incision Congenital Heart Surgery in Children: A Retrospective Cross‐Sectional Study
Authors' conclusion
The identified independent risk factors for atelectasis include younger age, higher BMI, prolonged anesthesia duration, sufentanil dose exceeding 2.0 μg·kg-1·h-1 and higher doses of cisatracurium, with the severity of atelectasis progressively worsening over time.

Main finding
As reported in the abstract
Independent risk factors for atelectasis (multivariable linear regression)
- Younger age: β = −0.03, 95% CI −0.04 to −0.02, p < 0.001
- Higher BMI: β = 0.55, 95% CI 0.41-0.69, p < 0.001
- Prolonged anesthesia duration: β = 0.01, 95% CI 0.004-0.02, p = 0.001
- Sufentanil dose > 2.0 μg·kg-1·h-1: β = 1.45, 95% CI 1.01-1.89, p < 0.001
- Higher cisatracurium doses: β = 1.17, 95% CI 0.65-1.69, p < 0.001
- Aggravating trend of atelectasis: β = 0.16, 95% CI 0.09-0.23, p < 0.001
- R2 = 0.699, adjusted R2 = 0.691, F-statistic = 89.068
Observational data: associations, not effects.
