  2. Peritoneal fluid - Wikipedia

    en.wikipedia.org/wiki/Peritoneal_fluid

    Peritoneal fluid is a serous fluid made by the peritoneum in the abdominal cavity which lubricates the surface of tissue that lines the abdominal wall and pelvic cavity. It covers most of the organs in the abdomen. An increased volume of peritoneal fluid is called ascites. Sampling of peritoneal fluid is generally performed by paracentesis.

  3. Serum-ascites albumin gradient - Wikipedia

    en.wikipedia.org/wiki/Serum-ascites_albumin_gradient

    The increase in hydrostatic pressure causes more fluid to leave the circulation into the peritoneal space (ascites). The SAAG subsequently increases because there is more free fluid leaving the circulation, concentrating the serum albumin. The albumin does not move across membrane spaces easily because it is a large molecule.

  4. Ascites - Wikipedia

    en.wikipedia.org/wiki/Ascites

    Ascites (/ ə ˈ s aɪ t i z /; [5] Greek: ἀσκός, romanized: askos, meaning "bag" or "sac" [6]) is the abnormal build-up of fluid in the abdomen. [1] Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. [4]

  5. Paracentesis - Wikipedia

    en.wikipedia.org/wiki/Paracentesis

    Cytopathology of peritoneal fluid from paracentesis , showing typical features of adenocarcinoma. It is used for a number of reasons: [3] to relieve abdominal pressure from ascites; to diagnose spontaneous bacterial peritonitis and other infections (e.g. abdominal TB) to diagnose metastatic cancer; to diagnose blood in peritoneal space in trauma

  6. Fluid wave test - Wikipedia

    en.wikipedia.org/wiki/Fluid_wave_test

    In medicine, the fluid wave test or fluid thrill test is a test for ascites (free fluid in the peritoneal cavity). It is performed by having the patient (or a colleague) push their hands down on the midline of the abdomen. The examiner then taps one flank, while feeling on the other flank for the tap.

  7. Abdominal examination - Wikipedia

    en.wikipedia.org/wiki/Abdominal_examination

    Depending on the need to test for specific diseases such as ascites, special tests may be performed as a part of the physical examination. [2] An abdominal examination may be performed because the physician suspects a disease of the organs inside the abdominal cavity (including the liver, spleen, large or small intestines), or simply as a part ...

  8. Diagnostic peritoneal lavage - Wikipedia

    en.wikipedia.org/wiki/Diagnostic_peritoneal_lavage

    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 ...

  9. Rivalta test - Wikipedia

    en.wikipedia.org/wiki/Rivalta_test

    The Rivalta Test is a simple, inexpensive method that can be used in resource-limited settings to differentiate a transudate from an exudate. [1] It is a simple, inexpensive method that does not require special laboratory equipment and can be easily performed in private practice.
