Abstract: A 49-year-old man presented with verapamil toxicity complicated by hypotension and a junctional rhythm, in the context of deliberate self-poisoning with multiple drugs. The patient's hypotension normalised following the early use of high-dose insulin euglycaemic therapy (HIET), without the need for additional vasopressors it recurred when HIET was prematurely stopped, and again stabilised when HIET was recommenced. Consideration should be given to the early use of HIET in treating severe calcium channel blocker toxicity, rather than as a last resort after other therapies have failed.

Abstract: This prospective, observational, interventional study sought to determine if the introduction of resuscitative balloon occlusion of the aorta (REBOA) at an Australian adult major trauma centre would improve survival for major trauma patients. Patients aged 18-60 years, transported directly from scene with exsanguinating, sub-diaphragmatic haemorrhage and hypovolaemic shock (systolic BP 1.0 (4.74%). There were 13 (0.43%) patients with a systolic BP <70 mmHg and/or cardiorespiratory arrest on arrival. The mortality in this group was six out of 13 (46.15%). Of these 13 patients, there were two (0.07% of the total cohort) where REBOA was attempted. There were no eligible patients for whom REBOA was achieved. None of the six patients who died would have benefited from REBOA deployment. Despite considerable training and resource allocation to ensure 24-h availability, the introduction of REBOA failed to effectively demonstrate any impact on patient outcome. Despite retrospective literature supporting the introduction of REBOA, in this 14-month prospective study there was no evidence of benefit. Further studies may define indications and subgroups of patients who may benefit.

Abstract: A 22-year-old woman presented with methanol toxicity manifesting as headache, reduced conscious state and visual change after consuming home-made grappa. She progressed to a coma with fixed mydriasis and severe acidaemia (pH 6.55). She was treated with empirical antidote administration (intravenous ethanol) and enhanced elimination through haemodialysis. She survived despite her delayed presentation but developed significant neurological sequelae, including visual impairment. We provide an overview of key elements of diagnosis and recent updates in treatment recommendations.

Abstract: Early hyperoxia may be an independent risk factor for mortality in critically ill traumatic brain injury (TBI) patients, although current data are inconclusive. Accordingly, we conducted a retrospective cohort study to determine the association between systemic oxygenation and in-hospital mortality, in critically ill mechanically ventilated TBI patients. Data were extracted from the Australian and New Zealand Intensive Care Society Centre for Outcome and Resource Evaluation Adult Patient Database. All adult TBI patients receiving mechanical ventilation in 129 intensive care units between 2000 and 2016 were included in analysis. The following data were extracted: demographics, illness severity scores, physiological and laboratory measurements, institutional characteristics, and vital status at discharge. In-hospital mortality was used as the primary study outcome. The primary exposure variable was the 'worst' partial arterial pressure of oxygen (PaO2) recorded during the first 24 h in ICU hyperoxia was defined as > 299 mmHg. Adjustment for illness severity utilized multivariable logistic regression, the results of which are reported as the odds ratio (OR) 95% CI. Data concerning 24,148 ventilated TBI patients were extracted. By category of worst PaO2, crude in-hospital mortality ranged from 27.1% (PaO2 40-49 mmHg) to 13.3% (PaO2 140-159 mmHg). When adjusted for patient and institutional characteristics, the only PaO2 category associated with a significantly greater risk of death was < 40 mmHg [OR 1.52, 1.03-2.25]. A total of 3117 (12.9%) patients were hyperoxic during the first 24 h in ICU, with a crude in-hospital mortality rate of 17.8%. No association was evident in between hyperoxia and mortality in adjusted analysis [OR 0.97 (0.86-1.11)]. In this large multicenter cohort of TBI patients, hyperoxia in the first 24 h after ICU admission was not independently associated with greater in-hospital mortality. Hypoxia remains associated with greater in-hospital mortality risk and should be avoided where possible.

Abstract: This study aimed to determine whether airway education should be introduced to the continuing professional development (CPD) program for College of Intensive Care Medicine (CICM) Fellows. A random representative s le of 11 tertiary intensive care units (ICUs) was chosen from the list of 56 units accredited for 12 or 24 months of CICM training. All specialist intensive care Fellows (n=140) currently practising at the eleven ICUs were sent the questionnaire via email. Questionnaire data collection and post-collection data analysis was used to determine basic respondent demographics, frequency of certain airway procedures in the past 12 months, confidence with advanced airway practices in ICU, participation in airway education in the past three years, knowledge of can't intubate, can't oxygenate (CICO) algorithms, preference for certain airway equipment/techniques, and support for required airway education as a component of the CICM CPD program. All responses were tabled for comparison. Data was analysed to establish any significant effect of another specialty qualification and current co-practice in anaesthesia on volume of practice, confidence with multiple airway procedures, use of airway equipment, and support for airway education. In total, 112 responses (response rate 80%) to the questionnaire were received within four weeks 107 were completed in full (compliance 96%). All results were tabled. There is currently widespread support amongst CICM Fellows for airway skills education as a CPD requirement for CICM Fellows. Volumes of practice and confidence levels with different airway procedures vary amongst Fellows and further support the need for education.

Abstract: Current health professions education (HPE) institutions are based on an assembly-line hierarchical structure. The last decade has witnessed the advent of sophisticated networks allowing the exchange of information and educational assets. Blockchain provides an ideal data management framework that can support high-order applications such as learning systems and credentialing in an open and a distributed fashion. These system management characteristics enable the creation of a distributed autonomous organization of learning (DAOL). This new type of organization allows for the creation of decentralized adaptive competency curricula, simplification of credentialing and certification, leveling of information asymmetry among educational market stakeholders, assuring alignment with societal priorities, and supporting equity and transparency.

Abstract: The coronavirus disease 2019 pandemic has led to the manufacturing of novel devices to protect clinicians from the risk of transmission, including the aerosol box for use during tracheal intubation. We evaluated the impact of two aerosol boxes (an early‐generation box and a latest‐generation box) on intubations in patients with severe coronavirus disease 2019 with an in‐situ simulation crossover study. The simulated process complied with the Safe Airway Society coronavirus disease 2019 airway management guidelines. The primary outcome was intubation time secondary outcomes included first‐pass success and breaches to personal protective equipment. All intubations were performed by specialist (consultant) anaesthetists and video recorded. Twelve anaesthetists performed 36 intubations. Intubation time with no aerosol box was significantly shorter than with the early‐generation box (median (IQR [range]) 42.9 (32.9–46.9 [30.9–57.6])s vs. 82.1 (45.1–98.3 [30.8–180.0])s p = 0.002) and the latest‐generation box (52.4 (43.1–70.3 [35.7–169.2])s, p = 0.008). No intubations without a box took more than 1 min, whereas 14 (58%) intubations with a box took over 1 min and 4 (17%) took over 2 min (including one failure). Without an aerosol box, all anaesthetists obtained first‐pass success. With the early‐generation and latest‐generation boxes, 9 (75%) and 10 (83%) participants obtained first‐pass success, respectively. One breach of personal protective equipment occurred using the early‐generation box and seven breaches occurred using the latest‐generation box. Aerosol boxes may increase intubation times and therefore expose patients to the risk of hypoxia. They may cause damage to conventional personal protective equipment and therefore place clinicians at risk of infection. Further research is required before these devices can be considered safe for clinical use.

Abstract: This article describes an operational framework for implementing translational simulation in everyday practice. The framework, based on an input-process-output model, is developed from a critical review of the existing translational simulation literature and the collective experience of the authors’ affiliated translational simulation services. The article describes how translational simulation may be used to explore work environments and/or people in them, improve quality through targeted interventions focused on clinical performance atient outcomes, and be used to design and test planned infrastructure or interventions. Representative case vignettes are used to show how the framework can be applied to real world healthcare problems, including clinical space testing, process development, and culture. Finally, future directions for translational simulation are discussed. As such, the article provides a road map for practitioners who seek to address health service outcomes using translational simulation.

Abstract: We describe Irukandji syndrome (a painful hypercatecholaminergic condition caused by jellyfish envenoming) in Australia's Northern Territory. We collected prospectively a standardized data set on patients presenting to health facilities in the Northern Territory. Additional cases were identified retrospectively. Data collected included demographic, geographic, seasonal, and environmental features, as well as sting details, clinical manifestations, investigations, management, and outcomes. From 1990 to 2007, Irukandji syndrome affected 87 people. Age ranged from 1 to 51 years (64% male victims 41% children [63% indigenous]). Activities associated with stings included snorkeling or scuba ing (35%) and swimming (29%). Stings commonly occurred in water greater than 2 m deep (63%), with fine weather (73%) and still or light breeze (70%). Seasonal variation was bimodal peaks in May and October corresponded to prevailing offshore winds in the Darwin and Gove areas, respectively. Pain was severe (65%), with rapid onset (<30 minutes in 79%). Sting lesions (visible in 63%) were mild, and nematocysts (detected in 7 cases) had variable morphology. Systemic features were common, including hypertension and ECG abnormalities. Severe complications included troponin-level increases (2 cases) and cardiomyopathy with ventricular tachycardia (1 case), but no fatalities. Management included vinegar as first aid (66%), parenteral opioids (70%) (range 2 to 82.5 mg morphine equivalents in adults), and magnesium sulfate (3 cases). Hospital admission (49%) and aeromedical retrieval (16%) were commonplace. Irukandji syndrome in the Northern Territory was clinically consistent with previous studies but had distinct seasonal, geographic, and environmental features. Indigenous children in remote coastal communities are at risk, and there is room for improvement in prevention and management.

Abstract: This paper aimed to describe the airway practices of intensive care units (ICUs) in Australia and New Zealand specific to patients presenting with COVID-19 and to inform whether consistent clinical practice was achieved. Specific clinical airway guidelines were endorsed in March 2020 by the Australian and New Zealand Intensive Care Society (ANZICS) and College of Intensive Care Medicine (CICM). Prospective, structured questionnaire for all ICU directors in Australia and New Zealand was completed by 69 ICU directors after email invitation from ANZICS. The online questionnaire was accessible for three weeks during September 2020 and analysed by cloud-based software. Basic ICU demographics (private or public, metropolitan or rural) and location, purchasing, airway management practices, guideline uptake, checklist and cognitive aid use and staff training relevant to airway management during the COVID-19 pandemic were the main outcome measures. The 69 ICU directors reported significant simulation-based inter-professional airway training of staff (97%), and use of video laryngoscopy (94%), intubation checklists (94%), cognitive aids (83%) and PPE “spotters” (89%) during the airway management of patients with COVID-19. Tracheal intubation was almost always performed by a Specialist (97% of ICUs), who was more likely to be an intensivist than an anaesthetist (61% vs 36%). There was a more frequent adoption of specific airway guidelines for the management of COVID-19 patients in public ICUs (94% vs 71%) and reliance on specialist intensivists to perform intubations in private ICUs (92% vs 53%). There was a high uptake of a standardised approach to airway management in COVID-19 patients in ICUs in Australia and New Zealand, likely due to endorsement of national guidelines.
