What does it mean to Percuss the abdomen?
Percussion of the abdomen involves tapping the body to elicit sounds and determining whether the sounds are appropriate for the underlying structure of the quadrant. This provides information about the overall consistency of the abdomen as well as the size and borders of some of the underlying structures.
What does tympanic abdomen mean?
Tympanitic (drum-like) sounds produced by percussing over air filled structures. Dull sounds that occur when a solid structure (e.g. liver) or fluid (e.g. ascites) lies beneath the region being examined.
What are normal abdominal percussion sounds?
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.
Why is abdominal percussion performed?
Percussion is done to determine the size and density of the structures and organs inside of the abdominal cavity, and to detect the presence of air or fluid. While you may use direct percussion, indirect percussion enables better patient comfort (especially if he/she is presenting with a complaint of abdominal pain).
Is tympanic abdomen normal?
Normally, tympanic sound produced by air in the bowel loops will be heard. Tympanic sound is relatively long, high pitched, and loud. Occasional areas of dullness (lower pitched, shorter, and quieter sound than tympany) are produced by fluid and feces, and are normal as well.
What is a tympanic sound?
Tympanic sounds are hollow, high, drumlike sounds. Tympany is normally heard over the stomach, but is not a normal chest sound. Tympanic sounds heard over the chest indicate excessive air in the chest, such as may occur with pneumothorax.
What are the 4 parts in order for abdominal assessment?
The abdominal examination consists of four basic components: inspection, palpation, percussion, and auscultation. It is important to begin with the general examination of the abdomen with the patient in a completely supine position. The presence of any of the following signs may indicate specific disorders.
What kind of abnormalities can be found with percussion of the abdomen?
The sounds produced during abdominal percussion can help detect pathologies like organomegaly, intra-abdominal masses, and fluid accumulation.
What do they look for in abdominal assessment?
Documentation of a basic, normal abdominal exam should look something along the lines of the following: Abdomen is soft, symmetric, and non-tender without distention. There are no visible lesions or scars. The aorta is midline without bruit or visible pulsation.
What are percussion sounds?
Percussion of a body part produces a sound, like playing a drum. The sound is a sign of the type of tissue within the body part or organ. Lungs sound hollow on percussion because they are filled with air. Bones, joints, and solid organs such as the liver sound solid.
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.
What is tympanic bowel sounds?
Where is tympany heard in the abdomen?
Tympany is typically heard over air-filled structures such as the small intestine and the large intestine. Dullness is typically heard over fluid or solid organs such as the liver or spleen, which can be used to determine the margins of the liver and spleen.
How do you assess abdomen?
Assessing the abdomen
- Picture your patient’s abdomen in four quadrants.
- Place the diaphragm of your stethoscope lightly over the right lower quadrant and listen for bowel sounds.
- With the bell of your stethoscope, listen over the aorta, as shown, and the renal, iliac, and femoral arteries.
What does dull percussion mean?
Dullness is the normal sound heard when percussing tissues that are dense in consistency, such as the liver. Dullness is typically considered an abnormal sound if elicited with percussion over the lungs or the intestines, stomach, or bladder.
What are the five percussion notes?
There are five common terms used to describe percussion notes in the physical examination: tympanitic, hyperresonant, resonant, dull, and flat.
What does positive bowel sounds mean?
Increased (hyperactive) bowel sounds can sometimes be heard even without a stethoscope. Hyperactive bowel sounds mean there is an increase in intestinal activity. This may happen with diarrhea or after eating.
