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. ⋯ 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.

Anesthesia and Increased Hypercarbic Drive Impair the Coordination between Breathing and Swallowing.
Coordination between breathing and swallowing helps prevent aspiration of foreign material into the respiratory tract. The authors examined the effects of anesthesia and hypercapnia on swallowing-breathing coordination. ⋯ Anesthesia impaired the coordination between swallowing and respiration. Mild hypercapnia increased the frequency of swallowing during anesthesia and the likelihood of pathological swallowing. During anesthesia, the risk for aspiration may be further increased when ventilatory drive is stimulated.

49 Mathoura Road: Geoffrey Kaye's Letters to Paul M. Wood, 1939-1955.
From 1930 to 1955, Geoffrey Kaye, M. B. B. ⋯ He believed that the diffusion center which "49" was to become was not only realistic and achievable but also necessary if Australian anesthesia was to gain international prominence comparable to anesthesia in Europe and North America. In the end, the failure of "49" left Kaye estranged from Australian anesthesia for many years. How this estrangement affected Australian anesthesia is unknown.
