Values are expressed as median (25%–75% interquartile range).
*P values indicate differences between SGA plus BB and ETT plus BB patients. P < 0.05 was considered statistically significant.
Abbreviations: SGA, supraglottic airway; ETT, endotracheal tube; BB, bronchial blocker; WBC, leukocyte; CRP, C-reactive protein.
a
The mean arterial pressure (MAP) and heart rate (HR) were recorded immediately after insertion of SGA plus BB or ETT plus BB.
b
The peak airway pressure and tidal volume (VT) were recorded at 5 min after one lung ventilation.
