To evaluate the hemodynamic and respiratory effects of percutaneous transtracheal high-frequency jet ventilation (HFJV) during difficult intubation using fiberoptic bronchoscopy under general anesthesia. ⋯ Transtracheal HFJV under general anesthesia with etomidate, alfentanil, and vecuronium provided satisfactory hemodynamic conditions and pulmonary gas exchange. Percutaneous transtracheal HFJV can be used safely to manage patients with a difficult airway under general anesthesia using fiberoptic bronchoscopy.

Two patients are described in whom double-lumen endotracheal tube malplacement and its ventilatory consequences were not detected by infrared capnography. Problems were suspected on auscultation, and the malplacement was diagnosed by means of bronchospirometry. We conclude that bronchospirometry helps detect problems with endotracheal intubation.
