abdominal murmur

Abdominal vascular murmur examination is an auxiliary examination method for checking whether the abdomen is normal. Abdominal vascular murmurs have a role in the diagnosis of certain diseases. Vascular murmurs have arterial and venous murmurs. The formation mechanism is abdominal aortic aneurysm or stenosis. Abdominal vascular murmurs occur in renal artery stenosis; arterial murmur is often on the midline of the abdomen or on the abdomen, and is divided into systolic and diastolic phases; the vein is often in the umbilical or upper abdomen, which is continuous Beep; abdominal aortic aneurysm or abdominal aortic stenosis, biceps reflex center for cervical spinal cord 5-6 knots, knee tendon reflex center for lumbar pith 2-4 knots. Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: not fasting Tips: Keep the environment quiet and warm during the inspection, and actively cooperate with the doctor. Normal value No abnormal noise is heard during normal vascular auscultation. Clinical significance Abnormal result (1) The systolic vascular murmur (jet murmur) in the mid-abdominal often indicates abdominal aortic aneurysm or abdominal aortic stenosis. The former can touch the pulsating mass at this part; the latter is weakened, the lower limb blood pressure is lower than the upper limb, and the severe one cannot touch the dorsal artery of the foot. (2) systolic vascular murmurs in the left and right upper abdomen, often suggesting a narrowing of the renal artery, which can be seen in young hypertensive patients. (3) The murmur on both sides of the lower abdomen should be considered for stenosis of the radial artery. (4) When the left lobe liver cancer oppresses the hepatic artery or the abdominal aorta, a squeaky vascular murmur can also be heard at the mass of the mass. People who need to be examined: routine physical examination items, abnormal abdominals. Precautions Requirements for inspection: (1) The environment should be quiet and warm. In the cold season, the auscultation chest should be rubbed and then contacted with the body surface of the examinee. (2) The subject takes a certain position, usually taking a sitting position or a lying position. Sometimes you need to cooperate with respiratory movements or change your position before auscultation. (3) The inspection site should be fully exposed, and it is forbidden to auscultate the clothes through the clothes to avoid the friction of the clothes. The chest piece should be placed close to the body surface to avoid friction with the skin to produce additional sound. However, it is not advisable to use excessive force, resulting in pain in the examinee. (4) When auscultating an organ, the other organs should be neglected. For example, when listening to lung sounds or sounds, heart sounds and heart murmurs should be temporarily ignored. (5) Auscultation should be combined with visual diagnosis, palpation, and percussion. When auscultating the lungs, the upper, lower, left and right controls should be identified. Inspection process (1) General auscultation: The examiner uses the ear to listen to the sound emitted by an organ of the examinee, such as voice, cough, hiccup, breathing, crying, suffocation, bowel sounds, bone rubbing, and the like. (2) Direct auscultation: The examiner directly attaches to the body wall of the examinee with the auricle for auscultation, and the body sound heard by this method is very weak. This method is not hygienic and inconvenient to perform, and some parts are more difficult to use for direct auscultation, so it is only used in certain special or emergency situations. (3) Indirect auscultation method is a method of examination for auscultation with a stethoscope. This method is convenient and can be used in any position, and the sound of the movement of the organ can also be amplified. The indirect auscultation method is widely used. In addition to the heart, lungs, and abdomen, vascular sounds, subcutaneous emphysema sounds, muscle beam vibrato sounds, joint activity sounds, and fracture surface friction sounds can be heard. 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.
