To report a case of pulmonary soiling of the dependent and of the non-dependent remaining lung when a Univent tube was used to achieve one-lung ventilation (OLV). ⋯ Whenever a bronchial blocker is used for OLV, we should be cautious about the possibility that secretions accumulated distal to the blocker may contaminate the dependent or the non-dependent remaining lung.

To verify if correct ProSeal laryngeal mask airway (PLMA) placement may condition blind insertion of a gastric tube via the PLMA. ⋯ Partial or total visualization of the vocal cords makes the success of gastric tube insertion more probable. Considering that fibreoptic visualization of the glottic aperture is associated with ease of insertion of a gastric tube (P < 0.02), the authors recommend adjusting or reinserting the PLMA if difficulty during the initial positioning of the gastric tube is experienced.

The laryngeal mask airway (LMA) is used in nasal surgery but there is some concern of tracheal or laryngeal contamination with blood and secretions. We have evaluated the ability of the LMA to prevent airway contamination until full emergence from anesthesia. ⋯ Ninety-eight percent of patients had no or minimal contamination of the LMA. The 2% incidence of grade 2 LMA soiling is low and probably acceptable, since it did not result in symptoms of airway contamination. We suggest that the use of the LMA for nasal surgery may be appropriate.

This study assessed difficult airway management, training and equipment availability among Canadian anesthesiologists. ⋯ Our survey assessed current preferences, training and equipment availability for the difficult airway amongst Canadian anesthesiologists. Direct laryngoscopy and fibreoptic bronchoscopy were the preferred technique for intubation despite widespread availability of newer airway equipment. Lack of certain essential airway equipment and difficult airway training should be addressed.
