Hydration is a mainstay of treatment, but insufficient evidence exists to guide clinical practice. We aimed to assess whether intravenous hydration or nasogastric hydration is better for treatment of infants. In this multicentre, open, randomised trial, we enrolled infants aged 2-12 months admitted to hospitals in Australia and New Zealand with a clinical diagnosis of bronchiolitis during three bronchiolitis seasons (April 1-Oct 31, in 2009, 2010, and 2011). We randomly allocated infants to nasogastric hydration or intravenous hydration by use of a computer-generated sequence and opaque sealed envelopes, with three randomly assigned block sizes and stratified by hospital site and age group (2-<6 months vs 6-12 months). The primary outcome was length of hospital stay, assessed in all randomly assigned infants. Secondary outcomes included rates of intensive-care unit admission, adverse events, and success of insertion. This trial is registered with the Australian and New Zealand clinical trials registry, ACTRN12605000033640. Mean length of stay for 381 infants assigned nasogastric hydration was 86·6 h (SD 58·9) compared with 82·2 h (58·8) for 378 infants assigned intravenous hydration (absolute difference 4·5 h [95% CI -3·9 to 12·9]; p=0·30). Rates of admission to intensive-care units, need for ventilatory support, and adverse events did not differ between groups. At randomisation, seven infants assigned nasogastric hydration were switched to intravenous hydration and 56 infants assigned intravenous hydration were switched to nasogastric hydration because the study-assigned method was unable to be inserted. For those infants who had data available for successful insertion, 275 (85%) of 323 infants in the nasogastric hydration group and 165 (56%) of 294 infants in the intravenous hydration group required only one attempt for successful insertion. Intravenous hydration and nasogastric hydration are appropriate means to hydrate infants with bronchiolitis. Nasogastric insertion might require fewer attempts and have a higher success rate of insertion than intravenous hydration.

The present paper identifies the analgesia methods currently available in the prehospital setting so as to evaluate the various options and highlight areas for future research. A literature review of Medline and Embase databases from 1966 until the present was undertaken. Further hand searching of all the references identified in these papers was also performed. All current literature was analysed and categorized according to one of four levels of evidence using National Health and Medical Research Council of Australia guidelines (1999). There is a paucity of randomized control trials relating to prehospital analgesia. All published literature was level III or IV prospective or retrospective studies. Drug options used included nitrous oxide/oxygen mixtures, intravenous/intramuscular nalbuphine, intravenous tramadol and intravenous pure opiate agonists. The evidence supporting analgesic options in the prehospital setting is limited. There are few published data in this area despite the inadequacy of pain relief being recognized as a weakness in prehospital care. Prehospital analgesia is an area worthy of innovative methods for the administration of safe and effective analgesics without significant impact on transport times. Such methods should be prospectively evaluated in well-constructed trials.

Review of CPGs for croup from PREDICT sites and survey of specialist pediatric emergency physicians regarding croup management. PREDICT sites included 8 tertiary pediatric hospitals and 3 large mixed emergency departments in Australia and New Zealand. Nine of the 11 sites had a CPG for croup. Response rate was 94% (78/83). Adrenaline was recommended for moderate croup (3%), severe croup (52%), and life-threatening croup by (100%). Steroid therapy was recommended for mild croup (45%), for moderate croup (97%), for severe croup (97%), and for life-threatening croup (96%). Steroid choice was oral dexamethasone (60%) and oral prednisolone (38%). In severe croup, 77% used intravenous/intramuscular dexamethasone, 10% used intravenous/intramuscular methylprednisolone, and 8% used nebulized budesonide. Commonest dosage regimens were 0.15 mg/kg dexamethasone or 1 mg/kg prednisolone. A standard volume dosage regimen for nebulized adrenaline was used by 54%, whereas 39% used a weight-based formula. Clinical practice guidelines recommended 5 mg (11%) or 10 mg (33%) for standard volume dosing, and all CPGs using weight-based dosing recommend 0.5 mg/kg with maximum doses ranging from 5 to 15 mg. Croup management at PREDICT emergency departments is similar, based on oral steroids and nebulized adrenaline. The steroid and adrenaline regimens used by respondents and their CPGs were not consistent. This reflects limitations of available evidence for management of this common disease, highlighting the need for definitive trials, particularly in the management of mild croup.

(i) Review of CPGs for acute seizure management at PREDICT sites. (ii) A standardised anonymous survey of senior emergency doctors at PREDICT sites investigating management of status epilepticus (SE). Ten sites used seven different seizure CPGs. One site had no seizure CPG. First line management was with benzodiazepines (10 sites). Second line and subsequent management included phenytoin (10), phenobarbitone (10), thiopentone (9), paraldehyde (6) and midazolam infusion (5). Of 83 available consultants, 78 (94%) responded. First line management of SE without intravenous (IV) access included diazepam per rectum (PR) (49%), and midazolam intramuscular (41%) and via the buccal route (9%). First line management of SE with IV access included midazolam IV (50%) and diazepam IV (44%). The second line agent was phenytoin (88%); third line agents were phenobarbitone (33%), thiopentone and intubation (32%), paraldehyde PR (22%) and midazolam infusion (6%). Fourth line agents were thiopentone and intubation (60%), phenobarbitone (16%), midazolam infusion (13%) and paraldehyde (9%). Initial seizure management by CPG recommendations and reported physician practice was broadly similar across PREDICT sites and consistent with APLS guidelines. Practice was variable for second/third line SE management. Areas of controversy would benefit from multi-centred trials.

In 2004, an Australia and New Zealand-based paediatric emergency research network was formed, the Paediatric Research in Emergency Departments International Collaborative (PREDICT). The founding sites include all major tertiary children's hospital EDs in Australia and New Zealand and a major mixed ED in Australia. PREDICT aims to provide leadership and infrastructure for multicentre research at the highest standard, facilitate collaboration between institutions, health-care providers and researchers and ultimately improve patient outcome. Initial network-wide projects have been determined. The present article describes the development of the network, its structure and future goals.

We conducted a cross-sectional study of paediatric ED visits to all Paediatric Research in Emergency Departments International Collaborative (PREDICT) sites in 2004. Epidemiological data, including demographics, admission rates and diagnostic grouping, were examined and analysed using descriptive and comparative statistical methods. We compared the data, if possible, with published data from a US paediatric emergency research network (Pediatric Emergency Care Applied Research Network). A total of 351 440 ED presentations were analysed from 11 PREDICT sites. Mean patient age was 4.6 years and 55% were boys. Presentations were identified as 3% Aboriginal at Australian sites and 44% Maori/Pacific in New Zealand locations. According to Australasian Triage Scale (ATS), 5% were ATS 1 or 2 (to be seen immediately or within 10 min), 27% ATS 3 (to be seen within 30 min) and 67% ATS 4 or 5. Although ED visits peaked in late winter and early spring, admission rates remained unchanged throughout the year with an overall admission rate of 24%. Most frequent diagnoses were acute gastroenteritis, acute viral illness and upper respiratory tract infection. Asthma was the next most common. Pediatric Emergency Care Applied Research Network and PREDICT data showed differences in terms of ethnicity descriptions/distribution and admission rates. This is the first description of the epidemiology of patient presentations to major paediatric ED in Australia and New Zealand. It details baseline data important to future collaborative studies and for planning health services for children.

Intranasal fentanyl has the potential to eliminate many of the problems of narcotic administration in children. The aim of this study, conducted in a tertiary paediatric emergency department was to evaluate the safety and efficacy of intranasal fentanyl in children. Children in acute pain aged between three and 12 years inclusive were enrolled on presentation to the emergency department. Routine observations and pain scoring by the child and caregiver was undertaken prior to the child receiving fentanyl (20 micrograms for 3-7 year olds and 40 micrograms for 8-12 year olds) and at intervals of 5 min for 30 min Additional fentanyl at the dose of 20 micrograms was given 5 minutely as required. Caregivers and older children used a visual analogue scale (VAS) and the younger children used the Wong-Baker faces scale (WBS). Forty five children were enrolled with a mean age of 8.0 years. The median dose of fentanyl administered was 1.5 micrograms/kg. Mean pain score in 32 children using the VAS was 62.3 mm (95% confidence interval 53.2-69.4 mm) at presentation and reduced at 10 min to 44.6 mm (95% confidence interval 36.2-53.1 mm). In 16 children using WBS the initial mean reading was 4.0 (95% confidence interval 3.3-4.7) and reduced to 2.2 (95% confidence interval 1.3-3.1) at 10 min. Caregiver pain scores showed a mean preintervention pain score of 64.9 mm (95% confidence interval 57.7-72.2 mm) with a significant reduction at 10 min to 41.7 mm (95% confidence interval 34.7-48.6 mm). There was no significant alteration in pulse rate, respiratory rate, and blood pressure or oxygen saturations. There were no negative side-effects. Early and significant reduction in pain (compared to baseline assessments) was achieved in children using intranasal fentanyl by 10 min and sustained throughout the 30 min of observations. This raises the possibility of using intranasal fentanyl in children in the prehospital setting as well as a role for this form of analgesia as triage nurse-initiated administration in the emergency department.

All 11 sites participate in the Paediatric Research in Emergency Departments International Collaborative (PREDICT) research network. (a) A review of CPGs for acute childhood asthma from all PREDICT sites. (b) A standardised anonymous survey of senior emergency doctors at PREDICT sites investigating management of acute childhood asthma. CPGs for mild to moderate asthma were similar across sites and based on salbutamol delivery by metered dose inhaler with spacer and oral prednisolone. In severe to critical asthma, differences between sites were common and related to recommendations for: ipratropium use; metered-dose inhaler versus nebulised delivery of salbutamol in severe asthma; use of intravenous aminophylline, intravenous magnesium and dosing of intravenous salbutamol in critical asthma. The questionnaire (78 of 83 doctors responded) also revealed significant differences between doctors in the treatment of moderate to severe asthma. Ipratropium was used for moderate asthma by 42%. For severe to critical asthma, nebulised delivery of salbutamol was preferred by 79% of doctors over metered dose inhalers. For critical asthma, doctors reported using intravenous aminophylline in 45%, intravenous magnesium in 55%, and intravenous salbutamol in 87% of cases. Thirty-nine different dosing regimens for intravenous salbutamol were reported. CPG recommendations and reported physician practice for mild to moderate paediatric asthma management were broadly similar across PREDICT sites and consistent with national guidelines. Practice was highly variable for severe to critical asthma and probably reflects limitations of available evidence. Areas of controversy, in particular the comparative efficacy of intravenous bronchodilators, would benefit from multi-centre trials. Collaborative development of CPGs should be considered.

Using a prospective observational cohort study during the Winter Classic, a 2-day wilderness multisport endurance event held in rugged alpine terrain in Victoria, Australia, we sought details of demographics, pre-, intra-, and postrace injuries and illness. We employed chi-squared tests and iterative multivariate analysis. There were 33 respondents with 26 (78%) aged between 26 and 35 years. Seven (21%) developed symptoms consistent with exposure, and three (9%) developed asthma during the race. Competitors in the marathon pairs class had a 50% risk of exposure vs 12% for the individual class (p = 0.031). The number of times raced, nonsteroidal anti-inflammatory drug use, and increasing age were the other independent significant predictors of exposure. Twenty-three (70%) of the competitors were injured at some time during the race. The day 1 run was more commonly associated with injuries than other stages (39% injured, p = 0.0037). Increased amounts of training, previous musculoskeletal problems, and increased number of previous race attempts were all significant independent predictors of injury. Most competitors (67%) suffered musculoskeletal problems after the race, these typically being of the thighs and calves, but only two competitors required time off from their normal activities. We concluded that injuries in wilderness multisport endurance events are common, particularly in the run stages. These injuries are usually minor, but their frequency makes major injury an ever-present risk. Both injury and illness are more frequent in those who compete while carrying injuries. These events are high risk for the development of injuries and illness and require a high level of competitor preparation and readily available medical support.
