Review Comparative StudyThe role of physician staffing of helicopter emergency medical services in prehospital trauma response.
The crewing of Helicopter Emergency Medical Service (HEMS) for scene response to trauma patients is generally considered to be controversial, particularly regarding the role of physicians. This is reflected in HEMS in Australia with some services utilizing physician crewing for all prehospital missions. Others however, use physicians for selected missions only whilst others do not use physicians at all. ⋯ Studies were excluded if they compared physician teams with basic life support teams (BLS) teams rather than paramedics. Ambulance officers were considered to be paramedics where they were able to administer intravenous fluids and use a method of airway management beyond bag-valve-mask ventilation. Studies were excluded if the skill set of the ambulance team was not defined, the level of staffing of the helicopter service was not stated, team composition varied without reporting outcomes for each team type, patient outcome data were not reported, or the majority of the transports were interhospital rather than prehospital transports.

The object of this review is to discuss the recognition and treatment of septic shock in children based on principles of resuscitation, antibiotic use and recent therapeutic advances. ⋯ Septic shock remains a leading cause of morbidity and mortality in children. Early administration of empirical antibiotic therapy reduces mortality. The keystone of resuscitation is aggressive volume replacement. Adjunctive therapies to modulate the inflammatory response may further enhance outcome, but do not replace principles of resuscitation.

The controversy regarding the role of hyperbaric oxygen (HBO) in the treatment of carbon monoxide (CO) poisoning has been re-ignited following the publication of a further randomized controlled trial by Weaver et al., the results of which appear to conflict with our findings. Comparative analysis suggests that the apparent outcome differences may be secondary to the design, analysis and interpretation of the results of the two studies. ⋯ This stratification may be aided by the evolving availability of biochemical markers of brain injury and the finding that patients with transient loss of consciousness and poor performance on neuropsychological tests of the supervisory attention system are at higher risk of neuropsychological sequelae. We propose that those patients most at risk be admitted and receive more prolonged normobaric oxygen therapy whilst those with more minor CO-poisoning should be provided with normobaric oxygen of no less than 6 h duration and certainly until sign and symptom free.

ReviewCyclooxygenase-2 inhibitors: do they have a role in emergency department prescribing?
Cyclooxygenase-2 selective inhibitors (COXIB or CSI) have been released with a fanfare as efficacious and safer alternatives to traditional non-steroidal anti-inflammatory drugs. They purport to offer equivalent degrees of analgesia and an improved safety profile. ⋯ This review discusses the pharmacology of these agents and reviews recent literature regarding their effectiveness and safety. It endeavours to answer the question 'Should we be using COXIB in emergency departments in Australasia'?
