Most paediatric tracheal tubes are marked in centimetres from the tip. In 105 children, nasotracheal tube length was set at the level of the vocal cords such that all 3.0 and 3.5 mm internal diameter tubes were placed with the 3 cm mark at the cords, all 4.0 and 4.5 tubes were set at 4 cm at the cords and all 5.0 and 5.5 tubes were set at 5 cm at the cords. ⋯ Neither bronchial intubation nor accidental extubation occurred in any subject. This is an effective method to determine tracheal tube length which may be used for both oral and nasal intubation.

We reviewed all the references quoted in Volume 45 (1990) (n = 3967) and half the references quoted in Volume 49 (1994) (n = 2183) of Anaesthesia. The references were numbered sequentially and 100 references from each year were randomly selected. Citations of non-journal articles were omitted leaving 197 citations for careful scrutiny. ⋯ The elements most likely to be inaccurate were, in descending order of frequency, article title, author, and page number. There was no significant difference in the error rate between the 2 years. It is the responsibility of contributors to ensure that all references are carefully checked.
