What does ascites sound like on percussion?

Shifting dullness In a person with ascites, the flanks will sound dull and the midline should sound tympanic, creating an air-fluid level. Test for shifting dullness, which is a way to confirm that the dullness is caused by ascites.

What should a Percussing abdomen look like?

Normal findings on percussion include tympany over the stomach, epigastric area, and upper midline, and dullness over the liver, a full bladder, a pregnant uterus and the left lower quadrant over the sigmoid colon (if the patient is ready to have a bowel movement).

What should you hear when Percussing the abdomen?

The stomach “bubble” should produce a very tympanitic sound upon percussion over the left lower rib cage, close to the sternum. Percussion can be quite helpful in determining the cause of abdominal distention, particularly in distinguishing between fluid (a.k.a. ascites) and gas.

Does ascites sound hollow?

Diagnosis of Ascites When a doctor taps (percusses) the abdomen, the fluid makes a dull sound. If the person’s abdomen is swollen because the intestines are distended with gas, the tapping makes a hollow sound.

Is your abdomen hard or soft with ascites?

The shape of the abdomen may suggest that it contains fluid rather than fat. A person with ascites may also have a distended abdomen, which is hard and swollen. They may also experience rapid changes in weight and body shape.

What are normal percussion sounds?

There are four types of percussion sounds: resonant, hyper-resonant, stony dull or dull. A dull sound indicates the presence of a solid mass under the surface. A more resonant sound indicates hollow, air-containing structures.

What does fluid in the abdomen sound like?

The anterior gas-filled abdomen normally has a tympanitic sound to percussion, which is replaced by dullness where solid viscera, fluid, or stool predominate. The flanks are duller as posterior solid structures predominate, and the right upper quadrant is somewhat duller over the liver.

Can you hear bowel sounds with ascites?

You should note tympany over the air-filled bowel and dullness over areas of collected fluid. Have the patient lie facing you. Percuss from the upper side of his abdomen downward. If ascites is present, the fluid shifts downward, so you’ll hear tympany at first, then dullness over the area with fluid.

How can you tell the difference between belly fat and ascites?

Ascites and fat move and feel different. A doctor may examine a person’s abdomen when lying down and standing. The shape of the abdomen may suggest that it contains fluid rather than fat. A person with ascites may also have a distended abdomen, which is hard and swollen.

What does ascites feel like to the touch?

The fluid causes swelling that can make the tummy feel tight and very uncomfortable. It often develops over a few weeks but might happen over a few days. The fluid causes pressure on other organs in the abdominal area and may lead to: clothes feeling tighter or needing a bigger belt size.

Which type of percussion note would you hear over an abdominal tumor?

Dull or thudlike sounds are normally heard over dense areas such as the heart or liver. Dullness replaces resonance when fluid or solid tissue replaces air-containing lung tissues, such as occurs with pneumonia, pleural effusions, or tumors.

Is ascites hard or soft?

Both ascites and beer belly result in a large, protruding hard belly that can resemble that of a pregnant woman’s belly. Ascites often results in a rapid weight gain in contrast to a more gradual gain with beer belly development.

Is ascites stomach hard or soft?

Is ascites hard or jiggly?

Is ascites belly hard?

Is your stomach hard with ascites?

What is normal percussion sound?

When performing percussion, tympany is normally heard over fluid-filled organs such as the stomach, bladder, and bowels. The combination of air and fluid creates a drum-like sound. However, the sound may be more dull or flat if a client has adipose tissue or muscles over the abdomen, because of the increased density.

Which percussing findings are characteristic of ascites?

When percussing for ascites, a positive finding involves dullness over the flanks and tympany at midline when the patient is in the supine position. When the patient moves to a lateral decubitus position, the dullness will shift toward the table.

How is percussion used in the workup of ascites?

In addition to detection of ascites, percussion can be used to help define the nature of an abdominal mass. Tympany of an abdominal mass implies that it is gas filled (i.e., intestine). Percussion is also used to define liver size.

What is the difference between ascites and tympanitic percussion?

The ascites and thus dullness shifts to the side the patient is lying on, while the tympanitic area shifts to the top. Click on the video icon to see a discussion and demonstration of the techniques for abdominal percussion. Click on the interactive icon to practice percussion of the abdomen.
