venous auscultation

A venous auscultation examination is an auxiliary examination method for checking whether a blood vessel is normal. The characteristic of venous noise is that the murmur is obvious in the right neck. When the inhalation, the head turns to the left side and the inhalation of isoamyl nitrite, the noise is enhanced, the most loud when sitting or standing, the supine position and the compression vein, the noise It disappears. Through this examination, the lesion and the corresponding symptoms can be judged. This venous noise can be made clearer when anemia is caused by anemia and other causes. Basic Information Specialist classification: cardiovascular examination classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and schedule. Normal value In normal children or young people, sometimes in the right jugular vein (the upper bone of the bone) can hear the venous noise of the camp, when standing or when turning head to the left is clear, this may be a wide diameter of the jugular vein The upper vena cava is physiological, and the murmur disappears when the jugular vein is pressed with a finger. This venous noise can be made clearer when anemia is caused by anemia and other causes. Clinical significance Abnormal results: 1. Jugular snoring is physiological and can be found in healthy adolescents and anemia patients. It is caused by eddy currents when the blood flows through the spherical bulging at the confluence of the vein and the superior vena cava. Sometimes it can be transmitted to the aortic valve area above the anterior chest, the pulmonary valve area and its vicinity, and can be misdiagnosed as patent ductus arteriosus. Thyroid vascular murmur, or other murmurs in the heart, so should pay attention to identification. This sound is different from the vascular murmur of the thyroid, which increases with the heartbeat systole and does not disappear when the jugular vein is pressed. 2. Hepatic vein murmur, the murmur of the left branch of the portal vein rapidly flows into the dilated umbilical vein or the varicose vein to form a vortex. Found in the 1 gram - abalone syndrome, the main feature of this syndrome is the obvious expansion of the umbilical part of the abdominal wall. The twisted veins bulge on the skin, especially when standing, like a sea snake head. Any cause of portal cirrhosis, such as schistosomiasis, malaria, chronic alcoholism, kala-azar, syphilis, etc., can form ke-bow syndrome, which is a strong evidence of portal hypertension. 2 hepatic cavernous hemangioma, the disease can also smell the vein "battalion" sound, the pressure during the examination, the noise can be significantly weakened or disappeared. 3 After the submucosal vein or portal-venous anastomosis, this noise can sometimes be heard. 3. Abdominal wall snoring (abdominal wallvenoushum), seen in cirrhosis. Regular physical examination items for people who need to be examined, abnormal blood vessels. Precautions Forbidden before examination: Maintain a normal diet and schedule. Requirements for examination: The position of the examination is often in the umbilical or upper abdomen. The patient actively cooperates with the doctor during the examination. It is not suitable for strenuous exercise one hour before the examination. It is not appropriate to be overly stressed during the examination, so as not to affect the result. Inspection process The contents and methods of the inspection are as follows: 1. A soft, continuous murmur heard by the venoushum on the upper and lower sides of the neck, or on the medial side of the supraclavicular fossa, in a "嗡嗡" or "camp"-like sound. Lower or medium, the loudest in the middle of diastole. 2. Livervenous murmur (livervenousmurmur) refers to a continuous "battalion" sound that resembles a bee's shivering and low pitch sounds heard around the xiphoid and around the umbilicus. The characteristics of the noise, this sound is more obvious when sitting on the back or standing position, can be enhanced when inhaling deeply, and can also be enhanced after pressing the spleen, and even a slight tremor can be felt when the hand is lightly pressed at the loudest part of the noise. 3. Abdominal wall snoring (abdominal wallvenoushum) can hear a continuous venous snoring around the umbilicus or upper abdomen. Due to portal hypertension, the collateral veins of the abdominal wall are dilated and blood flow is increased. Not suitable for the crowd Inappropriate people: severe blood vessels and heart failure.
