Objective: To assess the safety and effectiveness of peripheral vasoactive drugs initiated during pre-hospital care and retrieval missions, in Queensland, Australia., Methods: Three years of retrospective data was gathered from two sources. Medical notes were reviewed using a search for any patient having 'inotrope' recorded on an electronic medical record. Each case was reviewed to include only peripheral infusions of adrenaline or noradrenaline. Clinical Governance records were searched for adverse events related to vasoactive drugs, alerted for review to ensure complete capture., Results: A total of 418 patients received peripheral infusions of adrenaline and noradrenaline over the 3-year period. No major complications were recorded either immediately or at Clinical Governance review. Minor complications were recorded in 4.7% of the cases, of which 3.5% occurred with peripheral vasoactives during the presence of the retrieval team. The frequency of use of peripheral vasoactives increased over the study period., Conclusions: In this retrospective data set there were no major complications of peripheral vasoactive drugs. Minor complications were similar to in-hospital use and related to vascular access and drug delivery., (© 2024 Australasian College for Emergency Medicine.)

Objective: Bariatric anatomy and physiology present added clinical challenges to the provision of safe critical care and patient transport. LifeFlight Retrieval Medicine provides air medical retrieval services in Queensland, Australia, and performs over 6,000 retrieval missions annually using rotary wing, fixed wing, and ground ambulance platforms., Methods: Bariatric patient retrievals were identified from the LifeFlight Retrieval Medicine electronic patient database. These cases were interrogated to quantify and describe adverse events during patient transport., Results: Over the study period from July 2019 to December 2021 11,096 patient retrievals were completed. Of these patients, 816 (7.3%) had a body weight ≥ 120 kg (range, 120-246 kg; median = 146 kg). Bariatric patients were more likely to be male (70%) and to require critical care interventions than nonbariatric patients (25.9% vs. 19.9%). There was an absolute 1.5% increase of high-interest events during patient retrieval, corresponding to a 1.9-fold increased relative risk. Five hundred eleven of 11,096 patients were intubated by the retrieval team, and 61 of these weighed ≥ 120 kg. Bariatric patients undergoing intubation were of similar age and sex, weighed significantly more, had nonsignificant trends toward poorer airway visualization by Cormack-Lehane laryngoscopic grade, and tended toward reduced first-attempt success compared with nonbariatric patients. Rates of airway adverse events (AAEs) were significantly increased for the bariatric group (30/61, 49.2%) compared with the nonbariatric group (135/450, 30.0%) (χ 2 likelihood ratio, P = .004). Postintubation desaturation was the most common AAE and was the only criterion significantly increased when comparing bariatric (26%) versus nonbariatric (12%) patients (χ 2 likelihood ratio, P = .005). Using patient weight as a continuous variable, nominal logistic regression revealed a significant effect of increasing weight on AAEs (χ 2 = 12.9, P = .0003) with a threshold of 105 kg providing an optimal 88% sensitivity for predicting AAEs. The odds of AAEs were increased significantly for those weighing 105 to 119 kg versus those weighing < 105 kg (odds ratio [OR] = 3.4; 95% confidence interval [CI], 1.6-7.5) and for those weighing ≥ 120 kg versus those weighing < 105 kg (OR = 2.5; 95% CI, 1.4-4.3). There was no difference between those weighing ≥ 120 kg versus those weighing 105 to 119 kg (OR = 0.73; 95% CI, 0.3-1.8)., Conclusion: Air medical retrieval of bariatric patients is safe despite an increased risk of adverse events. Strategies to optimize emergency anesthesia should be used to maximize safe intubation in bariatric patients., Competing Interests: Declaration of Competing Interest The authors have no relevant disclosures.

Objective: The introduction of emergency telemedicine care models is a common theme in health jurisdictions that include rural and remote populations. How the availability of these models influences the way clinicians manage traumatic road crashes is not yet fully understood. This study seeks to compare road crashes where telemedicine was and was not used and to identify any variables that may increase the likelihood of telemedicine usage by treating clinicians. Methods: Road crashes reported in the state Department of Transport and Main Roads (Queensland, Australia) crash database between January 1, 2019, and November 30, 2020 ( n  = 23,734) were compared to videoconferencing call logs to determine which crashes resulted in treatment that was supported by telemedicine ( n  = 204). Analysis was performed to examine differences in characteristics related to the crash depending on whether telemedicine support was requested. Results: Road crashes where telemedicine support was requested on average involved more casualties (1.6 vs. 1.41; t (11,287) = -3.26, p < 0.001, relative risk = 1.13). Crashes that occurred in rural settings accounted for most requests for telemedicine (65.68%; X 2  = 159.2, p < 0.001) and a greater percentage of crashes in remote locations (3.36% vs. 2.35%; X 2  = 256.97, p < 0.001, relative risk = 1.43). The use of telemedicine support for crashes was associated with a 13% increase in the mean number of casualties, compared to crashes where telemedicine support was not used. Conclusion: Telemedicine support is requested by clinicians providing emergency treatment in the management of road crashes that produce more severe injuries, involve multiple casualties, and take place in more rural settings or remote locations.

In Australia, over half a million people are admitted to hospital every year as a result of injury, and where you live matters. Rural populations have disproportionately higher injury hospitalisation rates (1.5-2.5-fold), higher rates of preventable secondary complications, higher mortality rates (up to fivefold), and higher costs (threefold) than patients injured in major cities. These disparities scale up rapidly with increased remoteness, and shift the service needle from 'scoop and run' to 'continuum of care'. Poorer outcomes, however, are not solely due to longer retrieval distances or delays; they arise from inefficiencies in one or more potentially modifiable factors in the chain of survival. After discussing the burden of injury in Australia, we present a brief history of retrieval services in Queensland and discuss how remoteness requires a different kind of service delivery with many moving parts from point of injury to definitive care. We next address the ongoing challenges for the Australian Trauma Registry, and how centralisation of data from the metropolitan cities masks the inequities in rural and remote trauma. There is an urgent need for accurate data from all service providers around Australia to inform state and federal governments, and we highlight the paucity of trauma data analysis in North Queensland. Last, we identify some major gaps in treating rural and remote polytrauma and en-route patient stabilisation, and discuss the relevance of combat casualty care research and practices. We conclude that a greater emphasis should be placed on collecting more robust trauma patient records, as only accurate data will drive change.

Objective: Critically unwell patients in rural and remote areas of Queensland, Australia, often require airway management with rapid sequence intubation before retrieval to a tertiary center. Retrieval Services Queensland coordinate retrievals and support rural hospitals, including via telehealth. This study compared the demographics of patients intubated by a retrieval team including a LifeFlight Retrieval Medicine doctor with those intubated by the local hospital team., Methods: This was a retrospective cohort study of patients intubated in hospitals in Queensland, Australia, requiring subsequent air medical retrieval between January and December 2019. The data collected included the time of day, mission priority, geographic location, diagnosis, and failure/assistance with intubation. Descriptive statistics were complemented by regression analyses., Results: In 2019, 684 patients were intubated in hospitals in Queensland, Australia, requiring air medical retrieval by a team including a LifeFlight Retrieval Medicine doctor. One hundred thirty-one (19.2%) were intubated by the retrieval team, and 553 (80.8%) were intubated by the hospital team. In the most rural and remote areas, 64 (43.2%) of the patients were intubated by the retrieval team compared with 84 (56.8%) by the hospital team., Conclusion: A retrieval team is more likely to intubate patients in remote hospitals in Queensland, Australia. Remote hospitals should be given preference for dispatch of the retrieval team for assistance with critical patients., (Copyright © 2021 Air Medical Journal Associates. Published by Elsevier Inc.
