Perioperative Factors and Radiographic Severity Scores for Predicting the Duration of Mechanical Ventilation After Arterial Switch Surgery
Authors' conclusion
Arterial switch operation results in a high incidence of ≥48-hour postoperative mechanical ventilation. Blood component transfusion is a potentially modifiable risk factor. The Brixia scores also may be used to characterize postoperative acute lung injury.

Median
| Outcome | Moderate ALI | No moderate ALI | P value |
|---|---|---|---|
| Brixia score, POD 1, moderate ALI vs not (24 h after ICU admission) | 15.0 (IQR 13.0–16.0) | 12.0 (IQR 10.0–14.0) | P = 0.046 |
- Brixia score, POD 1, moderate acute lung injury (ALI) vs not (24 h after ICU admission) — Median baseline Brixia score
- 11.0 (9.0-12.0)
