One-lung Ventilation for Patients With Laryngo-tracheal Stenosis: A Case Report and Literature Review.

Laryngo-tracheal stenosis (LTS) is a relatively rare disease, and conventional methods have difficulty achieving one-lung ventilation (OLV) when an anatomical abnormality exists. Selecting an appropriate method for patients with LTS can ensure oxygenation, collapse the lung, and reduce damage. The study intended to perform a comprehensive review of the literature and a systematic review to examine the characteristics and management of OLV for LTS patients. The research team performed a narrative review by searching the PubMed and China National Knowledge Infrastructure (CNKI) databases. The search used the keywords one-lung ventilation and tracheal stenosis. The team then performed a review, including the studies found in the search and the research team's own case study. The study took place at the First Hospital of Jilin University in Changchun, Jilin, China. The participant in the current case study was a 72-year-old, female patient with generalized tracheal narrowing. Nine participants achieved OLV through BB, with the anesthesiologist performing SLT and using extraluminal BB for six participants. Several methods can successfully achieve OLV for patients with difficult airways, but the current research team found that a small, single-lumen tube (SLT) and extraluminal bronchial blocker (BB) may be a better choice for patients with tracheal stenosis.
