The Focused Assessment with Sonography for Traumais a rapid, bedside, ultrasound examination performed to identify intra-peritoneal haemorrhage or pericardial tamponade.
FAST examines four areas for free fluid:
- Perihepatic & hepato-renal space
- Perisplenic
- Pelvis
- Pericardium
FAST assessment is indicated in trauma patients who give a history of abdominal trauma, are hypotensive, or are unable to provide a reliable history because of impaired consciousness due to head injuryor drugs.
FAST is an adjunct to the ATLS primary survey and therefore follows the performance of the ABCs. The ultrasound machine should be immediately available in the trauma room and its use should not interfere with the on-going assessment and management of the patient.
Small, portable ultrasound machines are now available which are highly appropriate to the trauma room environment. Standard FAST assessment is carried out using a curvilinear 2.5 or 3.5MHz probe.
