Multicenter StudyAustralian paediatric hyperbaric oxygen therapy 1998-2011.
For a large number of ischaemic, infective, inflammatory or traumatic conditions, hyperbaric oxygen therapy is either the only treatment or an adjunct that significantly reduces morbidity and mortality. The primary aim of this review is to identify clinical conditions treated in a paediatric population referred to Australian hyperbaric units. Secondary aims are to describe outcomes of treatment and detail any complications occurring during treatment or during transfer between units. ⋯ Central nervous system oxygen toxicity occurred in 1:366 treatments. Our findings indicate that provision of hyperbaric oxygen therapy to children is feasible in major regional hyperbaric units and is associated with low complication rates. Management of children in an adult hyperbaric facility, however, requires significant cooperation between paediatric, intensive care and hyperbaric consultants, as the need for transfer to another hospital and prolonged transports often impacts on optimal ongoing surgical and intensive care management.

Multicenter StudyBlood loss and replacement for paediatric cranioplasty in Australia - a prospective national audit.
We prospectively audited blood loss and blood replacement in every child less than 24 months of age undergoing cranioplasty for craniosynostosis in Australia during 2008, in order to obtain more accurate data for the discussion of perioperative transfusion risk. A total of 127 cases were performed at seven centres. There were no directed or autologous blood donations. ⋯ Children with recognised craniofacial syndromes and those undergoing repeat surgery appeared to have greater blood loss and blood product exposure. There were two cases of sudden massive haemorrhage secondary to dural venous sinus tear, but no death or perioperative cardiac arrest. These findings indicate that blood loss requiring blood product replacement is common in patients <24 months of age undergoing cranioplasty for craniosynostosis, particularly in patients undergoing FOA and CVR.

Multicenter StudyThe critical care costs of the influenza A/H1N1 2009 pandemic in Australia and New Zealand.
The aim of this study was to determine the critical care and associated hospital costs for 2009 influenza A/H1N1 patients admitted to intensive care units (ICU) in Australia and New Zealand during the southern hemisphere winter All 762 patients admitted to ICUs in Australian and New Zealand between 1 June and 31 August 2009 with confirmed 2009 H1N1 influenza A were included. Costs were assigned based on ICU and hospital length-of-stay, using data from a single Australian ICU which estimated the daily cost of an ICU bed, along with published costs for a ward bed. ⋯ A multivariate analysis found death was significantly associated with a reduction in the log of total costs, while the use of mechanical ventilation and ICU admission with viral pneumonitis/acute respiratory distress syndrome or secondary bacterial pneumonia were significantly associated with an increase in the log of total costs. The cost of 2009 H1N1 patients in ICU was significantly higher than the previously published costs for an average ICU admission, and the total cost of treating 2009 H1N1 patients in ICU admitted during winter 2009 was more than $65,000,000.

Multicenter StudyA survey of anaesthetists' perspectives of communication in the operating suite.
We surveyed 222 anaesthetists attending a University of Western Australia conference (n = 110) and two public hospitals in Perth (n = 112) by anonymous questionnaire in March 2006 regarding communication issues in the operating suite. Forty-one percent (n = 92) responded. Questions concerned communication skills, experiences of good and poor communication and relationship to outcome, attitudes to music and communication courses. ⋯ Sixty-four percent of respondents would attend a communications course voluntarily, with implementation of a compulsory communications course supported by 45%. Most anaesthetists surveyed used staff first names and 94% believed poor communication caused procedural delay. The data suggest that further work is required to improve communication in the stressful operating room environment, particularly at the surgeon/anaesthetist interface.

Multicenter StudyVentilation and weaning practices in Australia and New Zealand.
Using a one-day prospective point prevalence design, this study aimed to characterise the current practice of mechanical ventilation and weaning in Australian and New Zealand intensive care units. During 2005, a bi-national one-day survey of 55 intensive care units found the point-prevalence of mechanical ventilation to be 284/491(58%). Common modes used were synchronised intermittent mandatory ventilation with pressure support, pressure support ventilation (each 116/284, 41%) and pressure-control modes (48/284, 17%). ⋯ Apart from 24/255 (9.4%) patients who received only pressure support ventilation, weaning methods (attempted in 255 patients, 29 prior deaths) included: change to pressure support ventilation (186/255, 73%), T-piece (31/255, 12%) or other methods (14/255, 5.5%). The point prevalence of mechanical ventilation was greater than comparable international studies. Australian and New Zealand intensive care unit ventilatory practices are similar, but differ substantially from published international survey results, due to a near absence of assist/control, prominent use of pressure-control modes and a preference forpressure support ventilation weaning as opposed to T-piece.
