It produces sound when slamming a parenchy organ covered with a small amount of gas-containing tissue, such as slamming the heart or liver. The part covered by the edge, or the percussion sound expressed in pathological conditions such as pneumonia (reduced air volume of lung tissue). Basic Information Specialist classification: growth and development check classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Inappropriate people: Basically no suitable for the crowd, but people with mental disorders should pay attention.

Mobility (-) is normal; mobility (+) indicates ascites. The sound produced when slamming a parenchy organ covered with a small amount of gas-containing tissue, such as the part of the heart or the liver covered by the edge of the lung, or the percussion of pathological conditions such as pneumonia (reduced air volume in the lung tissue) sound. Regular physical examination items for people who need to be examined, abnormal abdominals. Precautions Requirements for inspection: Due to the attention during the inspection, the following conditions may be mistaken for ascites: 1. When there is a large amount of fluid retention in the intestine, it may move due to the movement of the patient's body position, but often accompanied by signs of intestinal obstruction. 2.

Inspection process Let the inspected person lie on the back, starting from the abdomen, and percussing the abdomen on both sides. When there is dullness, the finger fingers do not leave the abdominal wall, so that the examinee is lying on the right side, so that the plate points at the highest point of the abdomen, and then the percussion is performed. When the percussion is to the lower side of the abdomen, the voice is voiced again, and then the examinee is lying on the left side, and the same method is used for slamming. This phenomenon of voiced sound changes due to different body positions is called mobile voiced sound if the amount of ascites is small. When the above method cannot be used, the patient can take the elbow and knee position so that the umbilicus is at the lowest position. Percussion from the lateral abdomen to the umbilicus, such as from drum sounds to voiced sounds, suggesting the possibility of ascites. It can also allow the patient to stand.
