Children frequently present to the emergency department with forearm injuries and often have an x-ray to assess if there is a fracture. Bedside ultrasound is a test that emergency practitioners can use to rapidly diagnose a fracture at the time of examination, without exposing children to ionising radiation. This trial will assess whether an x-ray is unnecessary when there is either a buckle fracture or no fracture seen on a portable ultrasound machine. We will also determine the time and cost implications of this new approach, which could enable families to go home earlier and could be more cost-effective, with less x-rays being ordered.

Most patients need intravenous cannula (a small plastic tube, inserted into the vein) in the emergency department, but many suffer multiple attempts before the health provider is successful. This can cause patient distress and delays the time to diagnose and to carry out potentially life-saving treatments. The study examines current practices of inserting intravenous (IV) cannulas in the Emergency Department at the Gold Coast University Hospital.

From this research, an ultrasound-guided cannulation training program, and other visual and written materials have been suggested. This will enable better recognition of patients with difficult intravenous access and increase ultrasound use during cannulation.
