Veterinary Dictionary: percussion
Top

In veterinary diagnosis, striking a part of the body with short, sharp blows of the fingers in order to determine the size, position and density of the underlying parts by the sound obtained. Percussion is most commonly used on the chest and back for examination of the heart and lungs. For example, since the heart is not resonant and the adjacent lungs are, when the examiner's fingers strike the chest over the heart the sound waves will change in pitch. This serves as a guide to the precise location and size of the heart. The value of percussion in animals is limited by their haircoat, their reluctance to cooperate and their anatomy. Radiology and ultrasonographic imaging have pretty much supplanted the percussionist.

  • auscultatory p. — auscultation of the sound produced by percussion. See also auscultation with percussion.
  • immediate p. — that in which the blow is struck directly against the body surface.
  • mediate p. — that in which a pleximeter is used.
  • palpatory p. — a combination of palpation and percussion, affording tactile rather than auditory impressions. See also ballottement.

Percussion is a method of tapping on a surface to determine the underlying structure, and is used in clinical examinations to assess the condition of the thorax or abdomen. It is one of the four methods of clinical examination, together with inspection, palpation and auscultation. It is done with the middle finger of the right hand tapping on the middle finger of the left hand, which is placed firmly on the body.

There are two types of percussion: direct, which uses only one or two fingers, and indirect, which uses the middle/flexor finger. 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.

Percussion was initially used to distinguish between empty and filled barrels of liquor, and Dr. Leopold Auenbrugger introduced the technique to medicine.

Percussion of the thorax

It is used to diagnose pneumothorax, emphysema and other diseases. It can be used to access the respiratory mobility of the thorax.

Percussion of the abdomen

It is used to find whether any organ is enlarged and similar. It is based on the principle of setting tissue and spaces in between at vibration. The sound thus generated is used to determine if the tissue is healthy or pathological.

Percussion notes

Based on the auditory and tactile perception, the notes heard can be categorized as [1]

  • Tympanic
  • Hyperresonant (pneumothorax)
  • Normal resonance/ Resonant
  • Impaired resonance (mass, consolidation)
  • Dull (consolidation)
  • Stony dull (pleural effusion)
