Abstract Background: Tracheal intubation compromises mucus clearance and secretions accumulate inside the tracheal tube (TT). The aim of this study was to evaluate with a novel methodology TT luminal obstruction in critically ill patients. Methods: This was a three-phase study: (1) the authors collected 20 TTs at extubation. High-resolution computed tomography (CT) was performed to determine cross-sectional area (CSA) and mucus distribution within the TT; (2) five TTs partially filled with silicone were used to correlate high-resolution CT results and increased airflow resistance; and (3) 20 chest CT scans of intubated patients were reviewed for detection of secretions in ventilated patients’ TT. Results: Postextubation TTs showed a maximum CSA reduction of (mean ± SD) 24.9 ± 3.9% (range 3.3 to 71.2%) after a median intubation of 4.5 (interquartile range 2.5 to 6.5) days. CSA progressively decreased from oral to lung end of used TTs. The luminal volume of air was different between used and new TTs for all internal diameters (P < 0.01 for new vs. used TTs for all studied internal diameters). The relationship between pressure drop and increasing airflow rates was nonlinear and depended on minimum CSA available to ventilation. Weak correlation was found between TT occlusion and days of intubation (R2 = 0.352, P = 0.006). With standard clinical chest CT scans, 6 of 20 TTs showed measurable secretions with a CSA reduction of 24.0 ± 3.9%. Conclusions: TT luminal narrowing is a common finding and correlates with increased airflow resistance. The authors propose high-resolution CT as a novel technique to visualize and quantify secretions collected within the TT lumen.

Abstract Background Nasotracheal intubation is a very useful technique for orofacial or dental surgery. However, the technique itself can be more traumatic than that of orotracheal intubation. Complications such as turbinectomy or bleeding are often reported. However, little is known about the follow-up of patients after these complications. Case presentation The present case describes an accidental middle turbinectomy that led to endotracheal tube obstruction during nasotracheal intubation, and discusses its long-term follow-up. A 19-year-old man underwent mandibular surgery under general anesthesia and nasotracheal intubation. His right middle turbinate was completely avulsed and became firmly occluded within the tube during nasotracheal intubation. The nasotracheal intubation was performed again and the operation was completed safely. The patient was discharged without sequelae after postoperative care. However, he had symptoms of nasal obstruction and sleep disturbance for 3 months postoperatively. Synechiae were detected between the nasal septum and lateral nasal wall on a right rhinoscopic examination and facial computed tomography at 3 months postoperatively. Additionally, he showed ipsilateral maxillary sinusitis on facial computed tomography at the 2-year follow-up examination. Conclusions Nasotracheal intubation can cause late complications as well as early complications. Therefore, if nasotracheal intubation is to be performed, the anesthesiologist should identify the nasal anatomy of the patient accurately and prepare appropriately. In addition, if complications occur, follow-up observation should be performed.
