Liver beat

The liver pulsation test is an auxiliary examination method for checking whether the abdominal liver pulsation is normal. Hepatic pulsations have conductive pulsations and dilated pulsations. Conductive pulsation is caused by the pulsation of the abdominal aorta under the liver. The dilated pulsation is caused by the contraction of the right ventricle through the right atrium and the inferior vena cava. The method of distinguishing between the two is to position the patient. The examiner presses the front of the liver with one hand and the back of the liver with the other hand. If both hands are feeling synchronous with the heart and heart beat (equivalent to the late contraction of the heart), it is a dilated pulsation of the liver; if only the hand in front of the liver has this feeling, the hand behind the liver does not have this feeling, indicating that the liver is pulsating. . Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: not fasting Tips: Cooperate with the doctor's inspection work. Normal value The normal liver does not touch the pulsation, and when the liver is pressed to the abdominal aorta or the right ventricle is enlarged to push down the liver, a liver pulsation may occur. Clinical significance Abnormal result Normal liver or hepatomegaly caused by inflammation, tumors, etc. is not accompanied by pulsation. When you touch the liver beat, you should pay attention to whether it is a conductive beat or an expansion beat. 1. Conductive pulsation is caused by the pulsation of the abdominal aorta under the liver. 2. Dilated pulsation is caused by the contraction of the right ventricle through the right atrium and inferior vena cava. The patient is in position and the examiner presses the front of the liver with one hand and the back of the liver with the other hand. If both hands are feeling synchronous with the heart and heart beat (equivalent to the late contraction of the heart), it is a dilated pulsation of the liver; if only the hand in front of the liver has this feeling, the hand behind the liver does not have this feeling, indicating that the liver is pulsating. . People who need to be examined: routine physical examination items, abnormal abdominals. 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. Repeatedly, the finger gradually moves toward the costal margin until it touches the liver margin or the costal margin. It is necessary to palpate the liver margin on the right midline and the front midline, respectively, and measure it with the costal margin or sword when breathing calmly. The distance from the root of the root, expressed in centimeters. Not suitable for the crowd Inappropriate people: Basically no suitable for the crowd, but people with mental disorders should pay attention. Adverse reactions and risks Nothing.
