The impact of a cadaver-based airway lab on critical care fellows' direct laryngoscopy skills.
This study sought to determine the impact of a cadaver-based airway lab on critical care medicine fellows' direct laryngoscopy skills and hypothesised that fellows can improve their self-reported percentage of glottic opening (POGO) scores in cadaver models to achieve POGO scores similar to that of expert faculty. Nineteen fellows attended an airway management skills laboratory utilising five modified cadavers. Initial fellow POGO (POGOi) visualised was recorded at the onset with direct laryngoscopy. ⋯ Clinical success rates of intubation were over 98%. A short training session using modified cadavers can be utilised to teach new critical care medicine fellows additional techniques for airway management and assist them in obtaining higher POGO scores, similar to those of expert instructors. Success rates of clinical intubations were favourable in the wake of this training.

Characteristics and outcomes of critically ill Aboriginal and/or Torres Strait Islander patients in North Queensland.
A retrospective cohort analysis of an admission database for the intensive care unit at The Townsville Hospital was undertaken to describe the characteristics and short-term outcomes of critically ill Aboriginal and Torres Strait Islander patients. The Townsville Hospital is the tertiary referral centre for Northern Queensland and services a region in which Aboriginal and Torres Strait Islander people constitute 9.6% of the population. Aboriginal and Torres Strait Islander patients were significantly younger and had higher rates of invasive mechanical ventilation, emergency admissions and transfers from another hospital. ⋯ Despite higher predicted hospital mortality for Aboriginal and Torres Strait Islander patients requiring emergency admission, no significant difference was observed (20.1% versus 19.1%, P=0.656). In a severity adjusted model, Aboriginal and/or Torres Strait Islander status did not statistically significantly alter the risk of death (odds ratio 0.88, 95% confidence interval 0.65, 1.2, P=0.398). Though Aboriginal and Torres Strait Islander patients requiring intensive care differed in admission characteristics, mortality was comparable to other critically ill patients.

Case ReportsMaternal pulmonary oedema during foetoscopic surgery.
We report a case of maternal pulmonary oedema necessitating intubation and ventilation with associated hyperchloraemic metabolic acidosis during foetoscopic laser surgery for twin-twin transfusion syndrome (TTTS), believed to be secondary to absorption of normal saline irrigation fluid. TTTS complicates 10% to 20% of monochorionic twin pregnancies and develops due to imbalanced vascular anastomoses and consequent unidirectional transfusion between the twins. The recipient is at risk of cardiac failure due to circulatory overload and the donor twin becomes hypoperfused. ⋯ Since the Eurofoetus study, laser ablation has been the mainstay of treatment for pre-viable TTTS, involving insertion of endoscopes transabdominally into the polyhydramniotic sac to allow visualisation and ablation of the anastosmotic vessels. Amnioreduction does not correct the underlying pathology and offers very little in advanced disease. Foetoscopic laser ablation leads to an improved survival past 28 days and a lower incidence of neurological complications compared to serial amnioreduction.

The epidemiology of sepsis during rapid response team reviews in a teaching hospital.
In a three-month retrospective study, we assessed the proportion of rapid response team (RRT) calls associated with systemic inflammatory response syndrome (SIRS) and sepsis. We also documented the site of infection (whether it was community- or hospital-acquired), antibiotic modifications after the call and in-hospital outcomes. Amongst 358 RRT calls, two or more SIRS criteria were present in 277 (77.4%). ⋯ Infection was hospital-acquired in 91 (57.2%) and community-acquired in 67 (42.1%) cases, respectively. Patients were on antibiotics in 127 of 159 (79.9%) cases before the RRT call and antibiotics were added or modified in 76 of 159 (47.8%) cases after RRT review. The hospital length-of-stay of patients who received an RRT call associated with sepsis was longer than those who did not (16.0 [8.0 to 28.5] versus 10 days [6.0 to 18.0]; P=0.002).

Hypertonic saline in paediatric traumatic brain injury: a review of nine years' experience with 23.4% hypertonic saline as standard hyperosmolar therapy.
We describe the protocolised use of 23.4% hypertonic saline solution (HTS) for intracranial hypertension in the context of traumatic brain injury in the paediatric population. This study represents the largest published data on the use of 23.4% HTS in the paediatric population. In this retrospective cohort, we focus on the efficacy, biochemical and metabolic consequences of 23.4% HTS administration in a Level 1 paediatric trauma centre. ⋯ Glasgow outcome scores of >3 (independent function) were achieved in 74% of patients. We describe the use of 23.4% HTS, demonstrating it to be a practical and efficacious method of delivering osmoles and may be advantageous in minimising total fluid volume. Thus, the bolus versus infusion debate may best be served via combining both approaches.
