Case ReportsHigh-frequency jet ventilation through a fibreoptic bronchoscope channel during lung lavage.
Simple manual ventilation facilitates removal of intra-alveolar accumulations. High-frequency jet ventilation can be performed through a narrow lumen like that of a fibreoptic bronchoscope. Accordingly, we expected that high frequency jet ventilation through a fibreoptic bronchoscope channel would facilitate lung lavage, and we developed a new bronchoalveolar lavage system, in which high-frequency jet ventilation through the channel of a fibreoptic bronchoscope was combined with conventional bronchoalveolar lavage. We describe a case in which this new lavage system, unlike conventional bronchoalveolar lavage, successfully removed the lipid material in the alveoli associated with pulmonary alveolar proteinosis.

A novel technique for post-pyloric feeding tube placement in critically ill patients: a pilot study.
Delivery of enteral nutrition in critically ill patients is often hampered by gastric stasis necessitating direct feeding into the small intestine. Current techniques for placement of post-pyloric feeding catheters are complex, time consuming or both, and improvements in feeding tube placement techniques are required. The Cathlocator is a novel device that permits real time localisation of the end of feeding tubes via detection of a magnetic field generated by a small electric current in a coil incorporated in the tip of the tube. ⋯ The Cathlocator accurately determined the position of both tubes without complication in all cases. The Cathlocator allows placement and location of an enteral feeding tube in real time in critically ill patients with slow gastric emptying. These findings warrant further studies into the application of this technique for placement of post-pyloric feeding tubes.

A questionnaire investigating substance abuse was sent to 128 anaesthetic departments in Australia and New Zealand of which 100 (78%) replied. Forty-four cases of substance abuse were reported. Abusers were more likely to be male, aged between 25 and 35 years and abusing opioids. ⋯ More than one precipitating cause was identified in 51% of cases, the most frequently reported were mental health and family problems. The pattern of substances abused was similar to that reported in the previous Australasian survey ten years ago. However, in keeping with an international trend, there appears to be an increased use of anaesthetic agents.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of the GlideScope with the Macintosh laryngoscope for tracheal intubation in patients with simulated difficult airway.
We compared the use of the GlideScope and the conventional Macintosh laryngoscope in a simulated difficult airway. The primary hypothesis was that time to intubation would be shorter using the GlideScope than using the Macintosh laryngoscope. After obtaining approval from the ethics committee and written informed consent, we recruited 60 ASA 1 and 2 patients to our randomized controlled trial. ⋯ Group G had a significantly shorter intubation time than group M (mean 41.8s +/- SD 20.2 vs mean 56.2s +/- 26.6, P < 0.05). The GlideScope improved the laryngeal view and decreased time for tracheal intubation time when compared with the Macintosh laryngoscope in patients with simulated difficult airway. The GlideScope may be a good alternative for managing the difficult airway but clinical trials evaluating its use on patients with an actual difficult airway are needed.
