Failure of anaesthetic machine automated self-check to detect massive leak in ventilator bellows

Anaesthetic machines are designed to provide for a safe, non-hypoxic gas mixture delivered to the patient. For this reason, anaesthetic machines provide a number of features to ensure such safety. Still, a number of anaesthetic societies, including the Association of Anaesthetists of Great Britain and Ireland [1], the American Society of Anaesthesiologists [2] and the Canadian Society of Anaesthesiologists [3] recommend that anaesthetic machines should be checked prior to each list, and prior to each case.peer-reviewe

The use of two novel techniques in the coagulopathic trauma patient in intensive care

Severe Trauma is a multisystem disorder with a high mortality in an often young population. It offers a big challenge to the intensivist, and any help that is available might prove decisive in saving the patient’s life. This case report highlights the use of two novel technologies in critically ill trauma patients, namely the use of activated recombinant factor VII (Novoseven®) to correct coagulopathy, and the use of a central venous oxygen saturation monitor (PresepTM with VigileoTM) to optimise perfusion.peer-reviewe

Anaesthesia and Intensive Care

The anaesthetist has seen his role steadily expand and it is hard to think of one medical specialty in which anaesthetists are not involved at least to some extent. We present a range of papers which demonstrates the breadth of anaesthesia: from its traditional realm in the operating theatre to critical care and resuscitation onto chronic pain and obstetric analgesia.peer-reviewe

Glycosylated haemoglobin (HbA1c) and cortisol levels on admission to intensive care as predictors of outcome

Objective: To evaluate the predictive value of glycosylated haemoglobin and cortisol on admission, in critical care patients. Design: Prospective, observational, single centre study. Setting: 14 bedded Intensive care unit of a tertiary-level university hospital. Patients: 124 consecutive emergency medical and surgical patients. Methods: Data collected on admission included patient demographics, medical history, medication, diagnosis, type of nutrition, TISS28 score, serum blood glucose, Glycosylated haemoglobin (HbA1c), cortisol, mean arterial blood pressure, and the use of inotropes in the first 24hrs. Daily baseline tests included complete blood count, urea and electrolytes, creatinine, twice weekly liver function tests. The primary outcome measure was intensive care unit mortality. Secondary outcome measures were ITU stay, days of ventilation, peak urea, peak creatinine, lowest platelet count, peak bilirubin, lowest Pa/FiO2, and the number of transfusions. Measurements and results: 124 patients (mean age 56.2 years SD 23.2) were included. Regression analysis was used to identify any potential predictors of outcome: HbA1c levels on admission were not found to be significantly associated with mortality (p=0.51), or any other secondary endpoints listed above. However, subgroup analysis revealed a predictive role of HbA1c with regards to length of ITU stay (p= 0.01) and number of days of ventilation (p=0.007) in those patients with a history of diabetes. Glucose level on admission emerged as an independent marker of mortality (p=0.009). Conclusions: This study suggests that HbA1c may not be a predictor of outcome in the general ITU population but may be of predictive value in diabetic ITU patients. On the other hand, blood glucose levels on admission emerged as a predictor of mortality, whilst no association was found between HbA1c and cortisol levels on admission.peer-reviewe

[In Press] Building a national Clinical Trials Network in child and youth mental health : Growing Minds Australia

Many fields of medicine have benefitted from the formation of clinical trials networks, whereby researchers come together on a large scale to identify high-priority questions and implement coordinated clinical trials. Clinical trials networks in the field of mental health, however, have been rare and largely absent from the Australian context. Here, we present an overview of the newly formed Growing Minds Australia Clinical Trials Network, which represents the first comprehensive clinical trials network in child and youth mental health in Australia. The 60 principal members of the Growing Minds Australia Clinical Trials Network represent teams across 19 diverse areas related to specific forms of psychopathology (e.g. internalising, externalising, neurodevelopmental disorders, early psychosis, substance use), specific research methods and processes (e.g. health economics, eHealth, implementation science) and specialised areas of practice (e.g. school-based systems, parenting interventions, Indigenous mental health, refugee families). Core functions of the Growing Minds Australia Clinical Trials Network include collaborative trial protocol development; peer review, prioritisation and endorsement of proposed trials; training; development of clinical guidelines; and consumer representation. The research by the clinical trials network will encompass the populations typically accessing youth mental health services, while placing a key emphasis on the early periods of life, and the role of parents and caregivers as critical partners in the co-design of research and the delivery of intervention and prevention strategies. The structures and processes built into the network are designed to coordinate collaboration between diverse stakeholders and ensure that provisions for translation are integrated into research from the outset. In this paper, we examine the potential for a dedicated clinical trials network to initiate fundamental improvement in child and youth mental health systems, and discuss the unique and complex challenges associated with establishing such an initiative
