Identified pelvic free fluid on a FAST exam in a patient following a motorcycle crash. Their patient is a 24 yo female who was involved in a motorcycle accident. Initially, the patient was normotensive with a heart rate in the 80s. Views in the LUQ and RUQ did not initially show obvious free fluid. In the sagittal view of the pelvis, shown below, there is a collection of free fluid posterior to the bladder. The fluid is not completely anechoic (black) - this is sometimes seen with blood. To get this image the probe is placed just above the pubic symphysis with the indicator marker pointed towards the head. To visualize structures posterior to the bladder you will often need to rock the probe so you are pointing into the pelvis.
