Upper limb disorders (affecting the hand, arm and neck) are common. The nature of anaesthetists' work poses a potential extra risk from poor posture that may contribute to the development of upper limb disorders in this professional group. However, to date, the problem has received scant attention in the literature. ⋯ Analysis of possible risk factors found a significant association between upper limb disorders and years since starting anaesthetic training, having children (irrespective of respondents' sex or the number of children) and right-handedness. Years of practice and having children are less modifiable identified risk factors. However, right-handedness may be linked to the ergonomic design of the environment/equipment used within this specialty and may thus be a potentially modifiable risk factor worthy of further investigation.

The primary objective of this quality improvement project was to measure and reduce the number of oxycodone immediate-release tablets dispensed to overnight stay surgical patients at discharge. The secondary objective was to reduce the proportion of inappropriate oxycodone immediate-release prescriptions at discharge. Interrupted time series analysis was performed in four surgical wards of St Vincent's Public Hospital, Sydney. ⋯ At the end of the first month of a fifth intervention, comprising audit-feedback plus individual academic detailing, the average number of oxycodone tablets decreased by 77 (95%CI 39-115) tablets/100 surgical cases, and the postintervention linear trend was a monthly reduction of 3.2 (coefficient -3.2 (95%CI -4.5 to -1.8); p = 0.001) tablets/100 surgical admissions. Baseline audit showed 27% of oxycodone prescriptions to be inappropriate. Following our intervention, this dropped to 17% (p = 0.048), and then to 10% (p = 0.002) after 3 years.

Proper placement of the tracheal tube requires confirmation, and the predominant method in addition to clinical signs is the presence of end-tidal carbon dioxide. Such is the importance of confirmation that novel methods may also have a place. We previously demonstrated using ex-vivo swine tissue a unique spectral reflectance characteristic of tracheal tissue that differs from oesophageal tissue. ⋯ The existence of the unique tracheal characteristic in both in-vivo swine and cadaver models was confirmed (p < 0.0001 for all comparisons between tracheal and oesophageal tissue at all target wavelengths in both species). Furthermore, our proposed tracheal detection algorithm exhibited a 100% positive predictive value in both models. This has potential utility for incorporation into airway management devices.
