Snake bite affects thousands of Australians every year, but few die as a result due to high quality first aid and timely medical care. Good first aid should be simple, standardised, use minimal or readily available equipment, and be able to be utilised effectively with no or minimal training by the rescuer. Over time the first aid methods used to manage snake bite in Australia have been questioned due to issues with efficacy, and some emerging evidence of harm from their use. There is little experimental data in the literature to support current first aid practices, and what exists suggests further research is required. Our study aims to examine and compare the effectiveness of two first aid methods by tracking the movement of a mock venom through the body when each first aid method is used. This will provide important information about the suitability of current techniques used in Australia and whether a proposed simpler alternative technique is as effective. If this is demonstrated to be correct it provides a basis for modifying current snake bite first aid recommendations.
READ MOREIn-flight hypotension (low blood pressure) leading to patient deterioration is a common and challenging clinical problem in aeromedical trauma patients. Predicting this risk is currently primarily based on clinical gestalt, without specific validated risk prediction tools. The Triage Revised Trauma Score (TRTS) is a clinical risk prediction tool calculated using only vital signs, making it well suited to the resource-limited pre-hospital environment.
A Life Flight Retrieval Medicine internal audit in 2021 suggested an association between the TRTS and in-flight hypotension for trauma patients. Based on these preliminary findings, this study will address the research question, “what is the relationship between pre-flight TRTS and in-flight hypotension in trauma patients undergoing aeromedical retrieval?”.
Knowledge gained from this study may allow aeromedical doctors to make more informed decisions about their patients before aeromedical transport.
READ MOREIn this study, we will compare the safety and effectiveness of ketamine and propofol in sedating acute psychiatric patients needing aeromedical retrieval. We believe that this is the first trial of its kind which will elucidate the complications, the safety profile and effectiveness of the two drugs in sedating acute psychiatric patients. The study will be a prospective, open-labelled, randomised controlled trial. Patients will be drawn the Northern Territory and Queensland. Through this study, we will better inform clinicians in their choice of a suitable sedation agent and potential provide an additional sedation choice in aeromedical and other critical care environments. Furthermore, this research has the potential to establish sedation guidelines in the aeromedical retrieval of acute psychiatric patients for Australia and internationally.
