Difficult airway equipment: a survey of standards across metropolitan Perth.
The importance of appropriate equipment to manage the difficult airway has been highlighted by the publication of the Australian and New Zealand College of Anaesthetists (ANZCA) guidelines in 2012. We set out to audit compliance with these guidelines in all public and private sites providing general anaesthesia in metropolitan Perth. Public and private health care websites identified 39 sites of which 37 were studied. ⋯ Capnography was available in 76% of post anaesthesia care units and used regularly in 27%. Adherence to the ANZCA guidelines regarding the DDAC could be improved. Standardised equipment across a metropolitan region would be of value in the management of the difficult airway.

Comparative StudyComparison of Massimo Pronto-7 and HemoCue Hb 201+ with laboratory haemoglobin estimation: a clinical study.
We prospectively studied agreement in haemoglobin estimation between two point-of-care devices (Pronto-7(®) Pulse CO-Oximetry(™), Masimo Corporation, Irvine, California, USA and HemoCue(®) Hb 201 +, HemoCue, Angelholm, Sweden) and an automated laboratory analyser (Sysmex XE5000, Sysmex Corporation, Kobe, Japan). Venous blood sampling and finger co-oximeter readings were performed on 141 pregnant women undergoing routine mid-trimester haemoglobin assessment. Three replicate measures were performed and analysis used Bayesian-based variance component modelling to provide estimates of repeatability, between person within method bias and precision. ⋯ Overall both devices are imprecise and 95% prediction limits wide. We present further prediction limits, derived from the posterior distribution and adjusted for any fixed bias for set levels of probability (certainty). These may be used to support clinical decisions when using these point-of-care devices.

A clinician's perspective on the first 20 years of the Australian and New Zealand Intensive Care Society Clinical Trials Group and its influence on intensive care clinical practice over this same time period. This point of view discusses the importance of the Clinical Trials Group and the significance of several major published research trials.
