The incidence of tracheal tube cuff rupture was noted in 30 polyvinyl chloride tracheal tubes lubricated with three different solutions. All cuffs moistened with water were intact after 2 hours of cuff inflation whereas two of 10 lubricated with 4% lignocaine solution had burst. Both of these had leaked at the site of cuff attachment to the tube. Fifty percent of tubes lubricated with Astra lignocaine spray burst during the study. Four of the five had developed pinholes in the cuffs themselves. The remaining 50% of this group showed marked distortion and thinning of their intact cuff walls. The implications of these findings are discussed in view of the widespread use of PVC tracheal tubes.

Background: Development of ventilator-associated pneumonia (VAP) is attributed to the microaspiration of pooled secretions around the cuff of airway devices. Despite the emphasis on the use of endotracheal tubes (ET) with subglottic secretion (SS) drainage ports to prevent VAP, the quality of the evidence for this recommendation remains moderate. This prospective observational study analyzed microbiological concordance between SS and endotracheal aspirate (ETA) cultures to generate further evidence in this regard.

Subglottic stenosis poses a rare but life-threatening risk for difficult tracheal intubation. Here, we report a unique case of undiagnosed subglottic stenosis discovered during emergency intubation of an 80-year-old woman with type 2 respiratory failure from infective exacerbation of asthma. A small calibre size 5.

Background: Considerable morbidity is attributable to inappropriate tracheal cuff pressure. An earlier study undertaken in our hospital revealed that a normal cuff pressure of 20-30 cm HO was achieved in only 6% of intubated patients using subjective estimation methods.
Objective: To determine whether a training intervention could improve the accuracy of the subjective estimation method in our tracheal cuff monitoring.

Purpose: To describe the effects of scoliosis severity on the trachea in patients with a tracheostomy tube.
Materials And Methods: A retrospective chart review of patients 21 years and younger with a tracheostomy and scoliosis between 2001 and 2019 was conducted at a single tertiary pediatric hospital. Patients with spine curvature from C6 - T3 (tracheal limits) were divided into two groups based on curvatures that were either greater than or equal to 30° (Group A) or less than 30° (Group B).
