Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
There are two main areas of emergency ultrasound. The Focused Assessment with Sonography for Trauma (or FAST) focuses on trying to ascertain if there is internal bodily fluid in blunt abdominal trauma, [3] in the areas between organs, which is a sign of severe internal injury. [10]
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Early fasting reduces amount of abdominal fat. Upon analysis, Ruiz and his team found that all fasting groups, regardless of the time-restricted fasting method, had more weight loss — on average ...
This procedure is performed when intra-abdominal bleeding (hemoperitoneum), usually secondary to trauma, is suspected. [2]In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for ...
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
Abdominal complaints: Abdominal pain is also a common complaint in the primary care and emergency department setting. Gallbladder disease is a frequent cause of abdominal pain, but can also result in critical illness. Bedside ultrasound assesses the gallbladder for presence of gallstones that cause the majority of gallbladder illness. Emergency ...
