Discordance between ROTEM® clotting time and conventional tests during unfractionated heparin-based anticoagulation in intensive care patients on extracorporeal membrane oxygenation.
We hypothesised that ROTEM® (Basel, Switzerland) INTEM® (ROTEM, Basel, Switzerland) clotting time (CT) would have good agreement with activated partial thromboplastin time (aPTT) in determining whether a dose adjustment should be made to the unfractionated heparin (UFH) infusion in patients on extracorporeal membrane oxygenation. All patients treated with extracorporeal membrane oxygenation over a five-year period were included for data analysis. Retrospective analysis was performed of prospectively collected data points, wherein aPTT, activated CT and ROTEM was performed simultaneously to monitor UFH-based anticoagulation. ⋯ While haemorrhagic complications were frequent, no major clotting complications were encountered. Our results demonstrated that aPTT and INTEM CT do not provide equivalent information to guide UFH infusion rate titration during extracorporeal membrane oxygenation. Our study suggests caution regarding the use of ROTEM for guiding UFH-based anticoagulation as it may lead to excessive UFH exposure.

Intentions and barriers to research activities among Australian and New Zealand anaesthetists: a Survey.
A voluntary, anonymous, cross-sectional online survey was conducted among 997 Fellows of the Australian and New Zealand College of Anaesthetists, using an electronic questionnaire. Details about their demographics, employment, research experience and barriers they had encountered, their perception about research and their future intentions to participate in research, were collected. The survey response rate was 24.6%. ⋯ In terms of barriers encountered during previous projects, 91% of the respondents cited methodological issues, which included complicated ethics approval processes, difficulty in coordinating teams or recruiting participants, non-compliant patients and difficulty in publishing. Sixty-three percent of those surveyed believed more exposure to research activities during training would increase the number of anaesthetists involved in research and scholarly activities. Through this survey, we have identified several areas that, if satisfactorily addressed, could enhance interest and participation in research amongst anaesthetists in Australia and New Zealand.

Intravenous fluid bolus therapy: a bi-national survey of critical care nurses' self-reported practice.
Knowledge of critical care nurses' intravenous fluid bolus therapy (FBT) practice remains underexplored. Using a multi-choice online survey conducted between September and October 2014, we sought to describe the self-reported practice of critical care nurses located in Australia and New Zealand. Two hundred and ninety-five critical care nurses responded to the survey with most practising in adult ICUs. ⋯ Overall, 0.9% saline remains the most common solution for FBT, but there are significant national differences in the preference for albumin and Plasma-Lyte. A volume of 250 ml defines a fluid bolus, with a range from 100 ml to >1000 ml, and speed of delivery from stat to 60 minutes. Most nurses expect substantial physiological effects with FBT.

Potential donor families' experiences of organ and tissue donation-related communication, processes and outcome.
We aimed to describe the experiences of families of potential organ and tissue donors eligible for donation after circulatory death or brain death. Forty-nine family members of potential donors from four Melbourne hospitals were interviewed to assess their experiences of communication, processes and the outcomes of donation. Interviews were recorded, transcribed verbatim and analysed thematically. ⋯ Many expressed they would benefit from a follow-up opportunity to ask questions and clarify possible misunderstandings. Overall, while experiences varied, Australian families valued frank communication, trusted health professionals, were satisfied with the care their family member received and with donation processes, despite some apparent difficulties. Family satisfaction, infrequently assessed, is an important outcome and these findings may assist education for Australian organ donation professionals.
