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.

ReviewPitfalls in haemodynamic monitoring in the postoperative and critical care setting.
Haemodynamic monitoring is a vital part of daily practice in anaesthesia and intensive care. Although there is evidence to suggest that goal-directed therapy may improve outcomes in the perioperative period, which haemodynamic targets we should aim at to optimise patient outcomes remain elusive and controversial. This review highlights the pitfalls in commonly used haemodynamic targets, including arterial blood pressure, central venous pressure, cardiac output, central venous oxygen saturation and dynamic haemodynamic indices. ⋯ Many dynamic haemodynamic indices have been reported to predict fluid responsiveness, but they all have their own limitations. There is also insufficient evidence to support that giving fluid until the patient is no longer fluid responsive can improve patient-centred outcomes. With the exception in the context of preventing contrast-induced nephropathy, large randomised controlled studies suggest that excessive fluid treatment may prolong duration of mechanical ventilation without preventing acute kidney injury in the critically ill.

Multicenter StudyEnhanced Protein-Energy Provision via the Enteral Route Feeding (PEPuP) protocol in critically ill surgical patients: a multicentre prospective evaluation.
Suboptimal levels of feeding in critically ill patients are associated with poor clinical outcomes. The Enhanced Protein-Energy Provision via the Enteral Route Feeding (PEPuP) protocol was developed to improve nutritional delivery in the critically ill and has been studied in several hospitals. However, the experience with this protocol in surgical patients is limited to date. ⋯ Although surgical PEPuP patients were more likely to receive trophic and volume-based feeds compared to surgical patients in control sites, other aspects of the PEPuP protocol were not adequately implemented. We conclude that nutritional delivery to surgical patients remains inadequate and the PEPuP protocol seems ineffective in improving nutritional intake in this population. Further research to determine methods of optimising PEPuP protocol implementation and adherence in surgery patients is needed.
