RESUMO
BACKGROUND: Rotational thromboelastometry (ROTEM) allows targeted and individualised blood product replacement. OBJECTIVES: The study aimed to determine the impact of ROTEM-guided transfusion on the clinical course of patients with acute massive haemorrhage in a regional Australian hospital. METHODS/MATERIALS: A retrospective review of all patients with acute massive haemorrhage that compared the characteristics, blood product use, and clinical outcomes of patients with massive haemorrhage before and after the introduction of ROTEM-guided transfusion. RESULTS: In per-protocol analysis, the 31/97 (32%) with ROTEM-guided transfusion used less packed red blood cells (median [interquartile range]: 6 [6-8] vs. 8 [6-12] units, p = 0.03) than patients whose transfusion was not ROTEM-guided. They were also less likely to receive fresh frozen plasma (2/31 [6%] vs. 45/66 [68%], p < 0.0001) or platelets (2/31 [6%] vs. 31/66 [47%], p < 0.0001); they were, however, more likely to receive fibrinogen products (26/31 [84%] vs. 38/66 [58%], p = 0.01). Patients receiving ROTEM-guided transfusion had lower in-hospital mortality (6/31 [19%] vs. 20/66 [30%], odds ratio 0.55 [95% confidence interval]: 0.20-1.55, p = 0.26) although this did not achieve statistical significance in this small cohort. CONCLUSION: ROTEM-guided massive transfusion of patients with acute haemorrhage in this regional Australian hospital led to a reduction in packed red blood cell, fresh frozen plasma, and platelet utilisation and may also have reduced mortality.

Venom-induced consumption coagulopathy (VICC) is one of the most dangerous syndromes caused by snake envenomation and can be caused by several snake species worldwide, including the Australian coastal taipan. Rotational thromboelastometry (ROTEM) provides real-time point-of-care information on all stages of clot formation; however, it has yet to be formally evaluated in the assessment of VICC. We report three cases of Taipan envenomation causing VICC and the associated ROTEM results. The implications for future use of ROTEM in the assessment, management, and further research of VICC are discussed.

With prompt administration of appropriate antimicrobial therapy and access to modern intensive care support, fatal pediatric melioidosis is very unusual. We describe cases of two children in whom the possibility of melioidosis was recognized relatively early, but who died of the disease, despite receiving optimal supportive care. We discuss the resulting implications for bacterial virulence factors in disease pathogenesis.

Paediatric melioidosis is uncommon in Northern Australia and localised skin and soft tissue infections predominate. This study presents data from Far North Queensland and shows that, in this population, children with melioidosis are commonly bacteraemia and have a high case fatality rate.

Paediatric bacterial meningitis is a neurological emergency which, despite advances in medical management, still has a significant morbidity and mortality. Over recent decades new vaccines have led to a change in epidemiology of the disease; however, it remains a condition that requires a high index of suspicion, prompt diagnosis, and early management in the emergency department. New laboratory techniques and clinical tools are aiding the diagnosis of bacterial meningitis, yet some controversies still exist in its management. This paper outlines the changing epidemiology of the disease, current diagnostic techniques as well as controversies and advances in the management of bacterial meningitis in the paediatric population.
RESUMO
PURPOSE: Dobutamine is recommended for patients with severe heart failure; however uncertainty exists as to its effect on mortality. This study aims to critically review the literature to evaluate whether dobutamine, compared with placebo or standard care, is associated with lower mortality and a range of secondary outcomes, in patients with severe heart failure. METHODS: A systematic review and meta-analysis of randomised controlled trials was performed. PubMed, EMBASE, the Cochrane Central Trials Registry, the metaRegister of Controlled Trials and bibliographies of retrieved articles were searched. Randomised trials comparing dobutamine with placebo or standard care, in human, adult patients with severe heart failure, were included if they reported at least one outcome of interest. Data regarding trial validity, methodological processes and clinical outcomes were extracted, and a meta-analysis was performed. RESULTS: Fourteen studies, with 673 participants, met the inclusion criteria and were included; 13 studies reported mortality. There was minimal heterogeneity (I(2) = 4.5%). The estimate of the odds ratio for mortality for patients with severe heart failure treated with dobutamine compared with standard care or placebo was 1.47 (95% confidence interval 0.98-2.21, p = 0.06). CONCLUSIONS: This meta-analysis showed that dobutamine is not associated with improved mortality in patients with heart failure, and there is a suggestion of increased mortality associated with its use, although this did not reach the conventional level of statistical significance. Further research to define the role of dobutamine in treatment of severe heart failure should be a priority.
