Demonstrates that subglottic diameter predicts endotracheal tube size in infants undergoing cardiac surgery, suggesting valuable tools for anesthesiologists in low-volume centers.
Subglottic diameter measured by USG reliably predict outer diameter of the ETT size in infants undergoing cardiac surgery. The finding is particularly valuable in low-volume centers where anesthesiologists may have limited experience with pediatric cardiac surgery.
