Description:
FAST involves assessment of the peritoneal cavity, pleural cavity and pericardial space. Learning that free fluid is present facilitates the most appropriate management plan. Additionally, the ability to detect free fluid has wider application, e.g. in ruptured ectopic pregnancy.
Pre-requisites
- Ultrasound: Indications
- Ultrasound: Physics
- Ultrasound: Image acquisition
After completing this session you will be able to:
- Explain the indications for a FAST scan
- Identify which probe to use and how to adjust the machine
- Describe how to position the probe on the patient
- Demonstrate Morrison’s pouch, the spleno-renal space, the pelvic cavity, the pericardial sac and the pleural cavity
- Recognise the appearances of free fluid in these spaces
- Evaluate when repeat or alternative imaging is required
