Huchard's sign is one of the lung examination items. There are two kinds of symptoms: 1 In patients with pulmonary edema, the examiner first auscultates the patient's lungs and finds that the lungs are covered with wet sounds, and then the same part is percussed. If it is found that it is not a normal unvoiced sound (an abnormal reaction occurs), it is called this, also called the summer lung sign. 2 Arteriosclerotic hypertension, when the position changes to the sitting position, the phenomenon of pulse rate reduction may occur. This is also known as the summer sign. Basic Information Specialist classification: Respiratory examination classification: pulmonary function test Applicable gender: whether men and women apply fasting: not fasting Tips: Taboo before check: poor rest, improper diet, excessive fatigue. Normal value The pulse is normal, the breathing is normal, and the chest sounds normal. Clinical significance Abnormal results pulmonary edema, lung field full of wet sound; arteriosclerotic hypertension, pulse rate reduction. People in the population who need to be examined have lung disease and cardiovascular disease. Precautions Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: 1. The auscultation environment should be quiet and avoid interference; warmth should be avoided to avoid the additional sound of the patient due to muscle bundle vibration; to avoid the wind, it is beneficial to obtain better auscultation effect. 2. Use the stethoscope correctly. Stethoscopes usually consist of three parts: earpieces, body parts and hoses, the length of which should be adapted to the length of the physician's arm. Before auscultation, you should check whether the direction of the earpiece is the correct position of forward, downward and inward, and whether the hard tube and the hose lumen are unobstructed. There are two types of body parts: bell type and film type. The bell type body is suitable for capturing low-pitched sounds, such as rumbling-type diastolic murmurs of mitral stenosis. When using, touch the body surface to be inspected, but care should be taken to avoid The additional sound produced by the friction between the body and the skin; the membrane-shaped body is suitable for listening to high-pitched sounds, such as murmurs of aortic insufficiency, breath sounds, intestinal squeaks, etc., should be used in close contact with the body surface to be inspected. 3. Pay attention to the double side contrast. Inspection process There are two cases: 1 In patients with pulmonary edema, the examiner first auscultates the patient's lungs and finds that the lungs are covered with wet voices, and then the same part of the percussion is found. If it is found that there is no normal unvoiced sound (an abnormal reaction occurs), that is, The sign, also known as the summer lung sign. 2 Arteriosclerotic hypertension, when the position changes to the sitting position, the phenomenon of pulse rate reduction may occur. This is also known as the summer sign. Not suitable for the crowd Inappropriate crowd: None.
