Randomized Controlled Trial
The use of ultrasound to guide time-critical cannula tracheotomy when anterior neck airway anatomy is unidentifiable.
Transtracheal or transcricothyroid placement of a cannula is a practice used in a number of aspects of airway management in anaesthesia and intensive care. In this study, we aimed to investigate whether the use of ultrasound will facilitate cannula placement in a time-critical situation in patients with difficult anterior neck airway anatomy. ⋯ If a 'can't intubate, can't oxygenate' scenario occurs in a patient with unidentifiable anterior neck airway anatomy in a location where an ultrasound machine is immediately available, we recommend that consideration is given to the use of ultrasound-guided cannula tracheotomy as the first-line rescue technique.

Randomised controlled trial (RCT) abstracts published in journal articles have traditionally been deficient of crucial information. To improve the quality of RCT abstracts, in January 2008, the Consolidated Standards of Reporting Trial (CONSORT) group published a checklist of essential information for inclusion. The current study assessed whether there has been an improvement in the quality of RCT abstracts published in main anaesthesia journals since this new guideline was introduced. ⋯ Despite some promising improvements and inter-journal differences, the overall quality of RCT abstracts and adherence to the CONSORT checklist for abstracts remains poor.

Perioperative myocardial ischaemia leads to an exceedingly high mortality. Previous studies have indicated that propofol pre-conditioning could mimic the cardioprotective effects of ischaemic pre-conditioning. The purpose of this study was to determine whether propofol post-conditioning is cardioprotective and to explore the possible molecular mechanism of propofol post-conditioning. ⋯ Propofol exerts cardioprotection when administered at the early phase of reperfusion. The effect is mediated through decrease in cardiomyocyte apoptosis and NF-κB nucleus translocation potentially via ERK signalling pathways.
