Double‑lumen endotracheal tube (DLT) are the most commonly used airway management tool in thoracic surgery. Due to the anatomical characteristics of the human airway, the right bronchus is shorter than the left. Thus, the opening of the right upper lobe may present anatomical variations. Using the existing right double‑lumen endotracheal tube (RDLT) may lead to poor separation, displacement tendency, and obstruction of the right upper lobe. To avoid these complications, various new RDLT designs have emerged, offering some novel potential clinical solutions. This paper summarizes the current clinically relevant improvement solutions of the RDLT, which could provide new ideas for product development and solutions of the existing clinical problems.
