scratch test

The squeegee test is an auxiliary test for checking whether the abdominal liver is normal. This test is mainly used to assist delimitation when the lower hepatic margin is not clearly diagnosed. The patient was placed in the supine position. The doctor held the stethoscope membrane body on the right side of the right clavicle midline rib. The right finger in the right clavicle midline from the bottom to the top in a "Z" shape gently scraped the right upper abdomen wall, or in the upper abdomen. The semi-circular equidistant range gently wipes the abdominal wall from the distal part of the membrane body. When it does not reach the liver margin, only a distant and slight sound is heard. When the skull is scraped to the liver surface, the sound is obviously enhanced. And near the ear. It is because the conduction of sound by a substantial organ is better than that of a hollow organ. This method is often used in patients with thicker abdominal wall or unsatisfactory coordination with palpation, and sometimes used to identify whether the right upper quadrant is a swollen liver. Once the lower edge of the liver is confirmed, it can be verified with palpation. This method can also be used to determine the stomach boundary. Basic Information Specialist classification: Digestive examination classification: liver function test Applicable gender: whether men and women apply fasting: not fasting Tips: When urinating, take a low-shoulder supine position, hands naturally placed on both sides of the body, the legs are slightly bent apart, the abdominal muscles are relaxed, and deep and uniform abdominal breathing is done. Normal value In order to further determine the edge of the liver and do this test, normal conditions do not occur when gently rubbing the abdominal wall and not reaching the liver margin, can not hear distant and slight sound, when the sputum scraped to the surface of the liver, there is no abnormal sound. This method is often used in patients with thicker abdominal wall or unsatisfactory coordination with palpation, and sometimes used to identify whether the right upper quadrant is a swollen liver. Once the lower edge of the liver is confirmed, it can be verified with palpation. Clinical significance Abnormal results: The clinical significance of this trial is to determine the edge of the liver; to determine ascites. The doctor holds the stethoscope membrane body on the right clavicle midline rib margin, and the right finger in the right clavicle midline from the bottom to the top in a "Z" shape gently scraping the right upper abdomen wall, or in the upper abdomen semicircular equidistance range The inside of the membrane body is gently scraped from the distance to the abdominal wall. When it reaches the liver margin, only a distant and slight sound is heard. When the skull is scraped to the surface of the liver, the sound is obviously enhanced and the ear is near. It is because the conduction of sound by a substantial organ is better than that of a hollow organ. People who need to check: Regular physical examination items, abnormal abdominal. Precautions Requirements for inspection: (1) The examinee should take the low-pillow supine position after urinating, the hands are naturally placed on both sides of the body, the legs are slightly bent apart, the abdominal muscles are relaxed, and the deep and uniform abdominal breathing is made. (2) The examiner should be on the right side of the examinee, and the forearm should be at the same level as the abdomen surface. The hand should be warm when inspecting, and the technique should be gentle. (3) Palpate the various parts of the abdomen in order. Generally, starting from the left lower abdomen, the examination is performed counterclockwise; the principle is to move from the bottom to the top, the first left and the right, and gradually move from the healthy part to the lesion area. (4) Observing the reaction and expression of the examinee while palpating, and giving comfort and explanation to those who are nervous or suffering. Inspection process The doctor holds the stethoscope membrane body on the left clavicle midline rib, and the right finger in the right clavicle midline from the bottom to the top in a "Z" shape gently scraping the right upper abdomen wall, or in the upper abdomen semicircle equidistant In the range, the abdominal wall is gently scraped from the far side to the membrane body. When it does not reach the liver margin, only a distant and slight sound is heard. When the skull is scraped to the liver surface, the sound is obviously enhanced and the ear is near. Not suitable for the crowd Inappropriate people: Basically no suitable for the crowd, but people with mental disorders should pay attention.
