ReviewReview article: Part one: Goal-directed resuscitation--which goals? Haemodynamic targets.
The use of appropriate resuscitation targets or end-points may facilitate early detection and appropriate management of shock. There is a fine balance between oxygen delivery and consumption, and when this is perturbed, an oxygen debt is generated. In this narrative review, we explore the value of global haemodynamic resuscitation end-points, including pulse rate, blood pressure, central venous pressure and mixed/central venous oxygen saturations. The evidence supporting the reliability of these parameters as end-points for guiding resuscitation and their potential limitations are evaluated.

Multicenter StudyImpact of pain location, organ system and treating speciality on timely delivery of analgesia in emergency departments.
This retrospective, observational cohort study investigated whether the clinical features of a patient's pain, including anatomical location, organ system and likely treating speciality, impact on the delivery of analgesia within 30 min in EDs. ⋯ Patients presenting with burns, orthopaedic conditions or with a limb location of pain are more likely to receive analgesia within 30 min in Australian EDs. Clinicians should be aware of possible trends in the delivery of timely analgesia to patients with pain.

ReviewReview article: Crisis resource management in emergency medicine.
Effective team management is a core element of expert practice in emergency medicine. Thus far, training in emergency medicine has focussed predominantly on proficiency in medical and technical skills, with emergency physicians acquiring these 'non-technical' skills in an ad hoc manner or by trial and error with varying levels of success. ⋯ They address areas, such as communication, leadership, knowledge of environment, anticipation and planning, obtaining timely assistance, attention allocation and workload distribution. We outline the application of these behaviours in the speciality of emergency medicine, and suggest that the teaching and practice of crisis resource management principles should become part of the curriculum for training and credentialing of emergency medicine specialists.

Randomized Controlled TrialHow fast does oral dexamethasone work in mild to moderately severe croup? A randomized double-blinded clinical trial.
For children with croup controversy remains over dosage and time to onset of action of oral steroids. The Cochrane Collaboration and other reviews have suggested 0.6 mg/kg dexamethasone be used (despite some evidence that 0.15 mg/kg is effective) with no expectation of benefit before 4-6 h. This randomized double-blinded clinical trial examines whether 0.15 mg/kg dexamethasone works by 30 min. ⋯ For children with croup an oral dose of 0.15 mg/kg dexamethasone offers benefit by 30 min, much earlier than the 4 h suggested by the Cochrane Collaboration. This result might encourage doctors to treat more children with all severities of croup being less worried about potential side-effects and delayed benefit.

Survey of paediatric intravenous fluid prescription: are we safe in what we know and what we do?
The administration of i.v. fluids to children is common in hospital. There are risks associated with fluid therapy, especially iatrogenic hyponatraemia. The objective of this study was to assess the workplace practices and knowledge of tertiary hospital doctors regarding paediatric i.v. fluid prescription. ⋯ Most doctors in this Australian tertiary hospital have a correct method for prescribing bolus and maintenance fluid rates. However, the potential for adverse events from i.v. fluid prescription remains. Further education in this area for junior doctors, introduction of standardized guidelines for fluid use and restriction of available fluid choice may reduce the risk of iatrogenic hyponatraemia in children.
