What is the nature of the emergence phenomenon when using intravenous or intramuscular ketamine for paediatric procedural sedation?
Ketamine has become the drug most favoured by emergency physicians for sedation of children in the ED. Some emergency physicians do not use ketamine for paediatric procedural sedation (PPS) because of concern about emergence delirium on recovery. The present study set out to determine the true incidence and nature of this phenomenon. ⋯ The belief that ketamine, in the doses used for ED PPS, causes frequent emergence delirium is flawed. A pleasant emergence phenomenon is common, but is not distressing for the child, and has no long-term (up to 30 days) negative sequelae. Rarely, there is anxiety or distress on awakening from ketamine sedation, which settles spontaneously. This should not deter emergency physicians from using ketamine for PPS.

Clinical TrialConfirmation of endotracheal intubation by combined ultrasonographic methods in the Emergency Department.
The objective of the present study was to investigate whether the combined use of transcricothyroid membrane ultrasonography and ultrasonographic evaluation for pleural sliding is useful for verifying endotracheal intubation in the ED. ⋯ The combination of transcricothyroid membrane ultrasonography and ultrasonographic lung-sliding evaluation could be useful in confirming endotracheal intubation in the ED.

Validation of a point of care troponin assay in real life Emergency Department conditions.
To validate the accuracy of a Point of care (POC) troponin device (Abbott i-Stat) in real life ED conditions. ⋯ The i-Stat POC device produces similar results in the hands of experienced and occasional operators in ED. There is good agreement between the POC and laboratory at levels used to diagnose infarction by older, more specific criteria. When compared using new lower cut-offs, the i-Stat had poor sensitivity.
