Stories That Inspire Global Impact

A retroperitoneal bleed is a hemorrhage occurring in the retroperitoneal space, the anatomical area behind the peritoneum. In the context of FAST (Focused Assessment with Sonography for Trauma) and trauma, identifying a retroperitoneal bleed with ultrasound can be challenging due to its deep location and the presence of bowel gas. While not directly visualized in…

The Focused Assessment with Sonography for Trauma (FAST) exam is a rapid, point-of-care ultrasound scan used in trauma to detect free fluid in the peritoneum, pericardium, and pleural spaces. This quick, non-invasive imaging technique is crucial for identifying internal bleeding or effusions that may require immediate medical intervention. Its portability and speed make it an…

The Extended Focused Assessment with Sonography for Trauma (E-FAST) exam is a rapid, point-of-care ultrasound performed in emergency and trauma settings. It builds upon the traditional FAST exam by adding thoracic views to evaluate for pneumothorax and hemothorax, alongside the standard assessment for free fluid in the abdomen and pericardium. This non-invasive ultrasound technique is…

Morrison's pouch, or the hepatorenal recess, is a crucial anatomical space located between the liver and the right kidney. In the context of FAST (Focused Assessment with Sonography for Trauma) exams, this area is a critical site for detecting free intraperitoneal fluid, such as blood, in trauma patients. Its dependent position makes it one of…

In FAST/Trauma ultrasound, the splenorenal recess, or splenorenal space, is a crucial anatomical landmark located between the spleen and the left kidney. This potential space is a key area for detecting free fluid, such as blood, following blunt abdominal trauma. Identifying fluid here is a critical indicator of splenic injury or other intra-abdominal hemorrhage during…

The suprapubic view in FAST (Focused Assessment with Sonography for Trauma) is a crucial ultrasound window used to assess the bladder and surrounding pelvic structures for free fluid. This view helps identify internal bleeding, such as hemoperitoneum, or bladder rupture in trauma patients. Its non-invasive nature and rapid acquisition make it essential in emergency settings…

Peritoneal fluid refers to any abnormal fluid accumulation within the peritoneal cavity, the space surrounding abdominal organs, a critical finding in FAST (Focused Assessment with Sonography for Trauma) exams. This fluid, often blood (hemoperitoneum) due to blunt or penetrating trauma, appears anechoic or hypoechoic on ultrasound. Prompt identification is crucial for diagnosing internal bleeding and…

Hemoperitoneum in FAST/Trauma ultrasound refers to the presence of free blood within the peritoneal cavity, typically a critical indicator of internal hemorrhage following blunt or penetrating abdominal trauma. Rapid identification via the Focused Assessment with Sonography for Trauma (FAST) exam is paramount for patient management, appearing as anechoic or hypoechoic fluid in dependent areas like…
