Study Objective: To determine whether tracheoscopy is an accurate and quick method for verifying correct placement of the tracheal tube after intubation. Design: Prospective, randomized study. Setting: Operating rooms of a teaching hospital. Patients: 26 patients scheduled for surgery and general anesthesia. Interventions: 8.0-mm tracheal tubes were inserted into both the trachea and the esophagus. Tracheoscopy was performed consecutively through both tracheal tubes by a variety of clinicians. Measurements: The times taken to correctly identify the trachea and the esophagus were recorded. Main Results: Correct identification of either the esophagus or the trachea occurred with a 100% sensitivity and a 96% specificity. The mean time to recognize either the trachea or the esophagus was 22.0 seconds. Conclusions: Tracheoscopy is a reliable method for quickly verifying proper endotracheal placement of a tracheal tube.
