Precautions Requirements for inspection: 1 When palpation, the palm should be close to the abdominal wall, up and down with the breathing movement. When inhaling, the speed of lifting the finger should lag behind the lifting of the abdominal wall; when exhaling, the finger should be pressed before the abdominal wall sinks. 2 Check the developed abdominal muscles, the right hand should be placed on the outer edge of the rectus abdominis to palpate upwards, avoiding the rectus abdominis as the lower edge of the liver. 3 In case of full right abdomen, the factors of liver should be considered. When palpation, the right hand should be placed in the midline of the right clavicle at the level of the vertical line of the abdomen or from the position of the right anterior superior iliac spine. Inspection process At the time of palpation, the examinee is in the supine position, the knee joints are flexed, the abdominal wall is relaxed, and deeper abdominal breathing is performed to move the liver up and down. The examiner is placed on the right side of the patient with one or both hands. One-handed palpation is more common. The examiner puts the right hand four fingers together, the metacarpophalangeal joint is straight, and is placed in parallel with the costal margin in the right abdomen to estimate the lower edge of the liver or below the percussive liver dullness. When the gas is blowing, the finger is pressed to the deep part of the abdominal wall. When inhaling, the finger is slowly raised, and the edge of the liver is moved upward toward the rib edge.
