Tracheal resection and reconstruction (TRR) is the treatment of choice for most patients with tracheal stenosis or tracheal tumors. Anesthesia for TRR offers distinct challenges, especially for the less experienced practitioner. This article explores the preoperative assessment, strategies for induction and emergence from anesthesia, the essential coordination between the surgical and anesthesia teams during airway excision and anastomosis, and postoperative care. ⋯ Targeted readership is practitioners with less extensive experience in managing airway surgery cases. As such, the article focuses first on the most common proximal tracheal resection. Final sections discuss specific considerations for more complicated cases.
