Tubeless Tracheal and Carinal Reconstruction

Tracheal/carinal resection and reconstruction remains a technically demanding procedure with high risks of morbidity and mortality. Traditionally, tracheal surgery is performed under intubated anesthesia, with intermittent endotracheal ventilation to maintain oxygenation during airway reconstruction. However, endotracheal intubation with cross-field ventilation obstructs the surgical field and potentially complicating the reconstruction procedure. Non-intubated anesthesia have has gained widespread adoption for modern thoracic surgery. However, the safety and feasibility of non-intubated tracheal and carinal reconstruction have not been studied by randomized controlled trial. So, this randomized controlled trial aims to evaluate whether the non-intubated approach offers comparable short-term and long-term outcomes to the conventional intubated procedure.
