The combination of ProSeal laryngeal mask airway and bronchial blocker did not significantly reduce hoarseness compared to the double-lumen endobronchial tube.

Coughing during emergence
- Less coughing in the pLMA+BB group vs DLT
Lung collapse and device placement-related outcomes
- Comparable between the groups
Safety
Intraoperative complications (hypoxemia, hypercapnia, surgical interruption, device malposition, unintended lung expansion, ventilatory difficulty)
- More intraoperative complications in the pLMA+BB group vs DLT
