Comparative StudyComparison of stress in anaesthetic trainees between Hong Kong and Victoria, Australia.
A postal survey was sent to anaesthetic trainees in Hong Kong and Victoria, Australia to compare work-related stress levels. Demographic data were collected. Anaesthetist-specific stressors, Maslach Burnout Inventory and Global Job Satisfaction scores were used for psychological testing. ⋯ Despite the complex nature of stress, its antecedents and manifestations, an inverse relationship between emotional exhaustion and job satisfaction was evident in correlation analysis (P < 0.001). This survey suggests that stress was present in some trainees in both areas. Hong Kong trainees may benefit from local development to address mental wellbeing as being important to fulfil this highly competitive training program.

Effect of recruitment and body positioning on lung volume and oxygenation in acute lung injury model.
The mechanism of oxygenation improvement after recruitment manoeuvres or prone positioning in acute lung injury or acute respiratory distress syndrome is still unclear. We tried to determine the mechanism responsible for the effects of recruitment manoeuvres or prone positioning on lung aeration using a whole lung computed tomography scan in an oleic acid induced acute lung injury canine model. Twelve adult mongrel dogs were allocated into either the supine group (n=6) or the prone group (n=6). ⋯ Prone positioning increased oxygenation (P=0.004) that also correlated with increase of the poorly- and well-aerated dorsal (nondependent) lung volume (r=0.787, P<0.001). However, the recruitment manoeuvre in the prone position had no effect on oxygenation despite an increase in ventral (dependent) lung volume. The increase in PaO2 after recruitment manoeuvres in the supine position or after prone positioning is related to the increase of the poorly- and well-aerated dorsal lung.
