The question of fluid volume in resuscitation has been identified as the top priority in sepsis research by emergency physicians in the United Kingdom, Australia and New Zealand. Guidelines and sepsis pathways recommend an initial intravenous (IV) fluid bolus of 30ml/kg isotonic crystalloid for patients with sepsis and hypotension. However, there is a lack of evidence from clinical trials to support this strategy. Both observational data as well as randomised studies suggest there may be harm associated with injudicious use of fluids in sepsis. Since there is equipoise regarding a more liberal or restricted fluid volume resuscitation as first line treatment for sepsis-related hypotension, we conducted the pilot multicentre REstricted Fluid REsuscitation in Sepsis-associated Hypotension (REFRESH) trial comparing a restricted fluid protocol with early initiation of vasopressor support against standard guideline care.
The data from REFRESH will inform feasibility of a large, multicentre phase III study. However, further ground work is essential for the optimal design of a Phase III trial that will provide valuable information on feasibility (road test recruitment rate and screening processes) as well as refinement of the protocol (sample size estimation, processes of care, prevalence of the population of interest, real world clinical practice regarding fluid use).
In this ARISE Fluids study, we aim to provide more insight into current practice by conducting a bi-national multi-site prospective observational study of fluid administration in (suspected) sepsis and hypotension in the Emergency Departments of Australia and New Zealand hospitals. Sites have been selected on the basis of having expressed interest in participating in a phase III trial.READ MORE
This study will collect information from the records of 3000 children from 30 hospitals presenting after a head injury in 2016 and will interview staff to look at different factors influencing the care provided. APHIRST-Gap is expected to provided crucial information on scan rates and inform strategies, including national guideline development to standardise and improve the care of children with head injury across Australia and New Zealand.
Head injury is a common reason children present to Emergency Departments in Australia and New Zealand. While most are minor the important issue for emergency clinicians is to determine whether a particular child is at risk of a serious head injury such as a bleed on the brain. A computerised tomography(CT) scan is the investigation of choice to look for these injuries. Its use is not without risks though, including those of sedation, and radiation induced cancer.
Several “rules” have been designed to guide doctors in the decision between risk of injury and risk of scan. The recently published Australasian APHIRST study examined three of these rules in our context. It found that all three rules performed well, clinicians made good judgements on who to scan, and the overall rate of CT scan use was low(10%). APHIRST was limited to 10 large metropolitan, and predominately children specific hospitals. Most children in Australia are not seen in these hospitals. Further research is required to determine whether there is a large variation in scan use between different hospitals and how best to apply these findings to a broader range of hospitals.
This trial is being run by the PREDICT network and the Principal Investigator is A/Prof Franz Babl.READ MORE
Sick and injured children in the Emergency Department (ED) often require procedures which can cause severe pain (like fracture reduction, stitching wounds, abscess drainage) or otherwise require the child to be still and cooperative (CT scans, lumbar punctures, removal of foreign bodies). Sedative drugs are given to these patients both to relieve pain/distress and to keep them still for the procedure.
ED sedation of children now has a well established body of evidence. Most of the literature relates to when the drug is given intravenously or intramuscularly. Drug delivery by these routes leads to reliable effects as the drug bypasses the liver without being broken down before it reaches the brain. However, both these routes require a needle which requires staff to hold down a young child against their will, frequently causing great distress along with the pain of the needle. Great efforts have gone into making EDs "Ouchless" where unnecessary pain for children is reduced or eliminated. Sedation is itself part of this effort. The intranasal route (injecting the medicine up the nose with a plastic syringe) could represent a needle-free alternative.
Ketamine is the most common drug used for paediatric sedation in Australian EDs and can be given intranasally. No studies have examined its use for ED sedation but many studies support its use in anaesthetics and dental clinics where it has been shown to be safe and effective.READ MORE
Primary spontaneous pneumothorax (PSP) is defined as a collapsed lung with air in the pleural cavity that occurs in the absence of clinically apparent underlying lung disease. PSP is a significant global health problem affecting adolescents and young adults. Throughout the 20th century the treatment of PSP was predominantly bed rest, with invasive treatment reserved for severely symptomatic episodes. A study in 1966 suggested that managing large and small PSP in the community was safe. Despite this, rates of intervention have steadily increased over the decades. The reasons for this are unclear and this approach has recently been questioned in the scientific literature. Preliminary data suggests that a conservative approach to management may allow faster healing and reduce the risk of recurrence from around 25 per cent to 5 per cent in the first year. Conservative management is also likely to reduce the risks of prolonged admission due to persistent leak from approximately 30 per cent to less than 10 per cent and of other complications related to interventional management. Clinicians are, however, unlikely to change a practice entrenched for decades and re-enforced by current international guidelines without robust evidence.
This study will significantly increase our understanding of Primary spontaneous pneumothorax and its optimal management. If allowing the lung to remain collapsed initially results in improved healing of the pleural defect and lower recurrence rates then this study will contribute to improve outcomes and a reduction in the morbidity associated with current treatment.READ MORE
The aims of this research are to link best practice ED workforce models to available ED funding under an activity-based funding (ABF), while contributing to the development of an improved national activity and outcome-based ED funding model. This research will identify the current status of funding of EDs, identify and critically appraise models for funding of EDs and identify the workforce implications of those funding models and propose a State-wide ED clinical workforce framework.READ MORE
This project aims to determine if the drug combination called ketafol offers an improved safety profile while maintaining the same procedural success rates and patient satisfaction. This study will still treat any pain before the procedure starts or the sedative drugs are administered for the procedure itself. Patients who agree to take part will receive one or other of the alternatives in predetermined amounts. All patients receive full monitoring and standard sedation care.
The second aspect to this study relates to the way in which the data will be viewed and analyzed. This study will be using a special database with visual interfaces that allows analysis of the data and comparison to what is already known about patients who have had procedural sedation in other studies.READ MORE
