The bowel sound test is an auxiliary test method for checking whether the abdomen is normal. When the intestines move, the gas and liquid in the intestines flow with it, producing an intermittent humming sound (or a sound of water over the water) called a bowel sound. The sound and tone of the bowel sounds vary greatly. The examiner should be patient and meticulous. The auscultation time should not be less than 5 minutes, or the auscultation should be repeated several times. The general auscultation examiner uses the ear to listen to the sound emitted by an organ of the examinee, such as voice, cough, hiccup, breathing, crying, suffocating, bowel, bone rubbing, and the like. Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: The normal bowel sounds are most clearly heard in the umbilicus, when the time is hidden, when the time is strong and weak, about 4 to 5 times per minute. Positive: 1. Increased bowel sounds: When the bowel movements are enhanced, the bowel sounds reach more than 10 times per minute, but the tone is not particularly high, and the bowel sounds are active. It is seen in acute gastroenteritis, after taking laxatives or when there is massive bleeding in the gastrointestinal tract; If the number of times and the bowel sounds bright, high sputum, or even a snoring or metal sound, called the bowel sounds hyperthyroidism, seen in mechanical intestinal obstruction. In this type of patients, the intestinal lumen is enlarged, the gas is increased, the intestinal wall is swollen and thin, and it is extremely tight. It can resonate with the hyperactive bowel sounds, so that the metallic tone of sorghum can be heard in the abdomen. If the intestinal obstruction persists, the muscle wall of the intestinal wall is strained, and the intestinal wall is weakened, the bowel sounds are also weakened. 2. The bowel sounds are weakened: the bowel sounds are obviously less than normal, or they are heard once in a few minutes, which means that the bowel sounds are weakened. It is seen in senile constipation, peritonitis, electrolyte imbalance (hypokalemia), low gastrointestinal motility, etc. . 3. The bowel sound disappears: If you continue to auscultate for 3 to 5 minutes without hearing the bowel sounds, you should focus on auscultating the right lower abdomen, and you can use your fingers to gently rub or rub the abdomen without bowel sounds, called the bowel sounds disappear. Found in acute peritonitis or paralytic ileus. Reminder: The inspection site should be fully exposed, and it is forbidden to auscultate through the clothes to avoid the friction of the clothes. Normal value The normal bowel sounds are most clearly heard in the umbilicus, when the time is hidden, when the time is strong and weak, about 4 to 5 times per minute.

Found in acute peritonitis or paralytic ileus. 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: a method of examining 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.
