fluid thrill

A fluidthrill test is an examination that aids in the diagnosis of a disease by examining the presence or absence of free fluid in the abdominal cavity. When there is a large amount of free liquid in the abdominal cavity, such as slamming the abdomen with a finger, you may feel fluidthrill, or fluctua-tion. There are many factors that cause ascites. The most important causes are increased portal pressure and hypoalbuminemia. After the presence of ascites, the abdominal wall tension increases. When the patient is upright, the lower abdomen is full. When lying on the back, the sides of the abdomen are swollen and frog-shaped. Basic Information Specialist classification: Digestive examination classification: biochemical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Inappropriate people: mentally abnormal. Normal value Normal people have no fluid tremors. When there is a large amount of ascites in the abdomen, there may be fluid wave tremor. Clinical significance Abnormal results When there is a large amount of free liquid in the abdominal cavity, such as slamming the abdomen with a finger, you can feel fluidthrill, or fluctua-tion. It means too much ascites, also known as ascites, which refers to fluid accumulation in the peritoneal cavity. It is the most prominent clinical manifestation in the late stage of cirrhosis. When a large amount of ascites increases the abdominal pressure, the umbilicus is pressed to form an umbilical hernia, and a large amount of ascites may have a liquid wave tremor. A large amount of ascites causes the diaphragm to rise and the movement is limited, and breathing difficulties and palpitations can occur. Pressing the inferior vena cava with ascites can cause renal pelvis and lower extremity edema. In some patients, abdominal pressure is increased due to a large amount of ascites, and ascites leaks into the chest through the thin diaphragm of the diaphragm and the pleural lymphatic vessels, resulting in pleural effusion. People who need to be examined have uncomfortable abdominal abdomen and people who perform routine physical examinations. Precautions Requirements for examination: 1 In order to avoid the abdominal muscle tension of the examinee, the examiner may first place the palm on the abdominal wall, so that the examinee can adapt to the moment and then palpate the examination; 2 the test can simultaneously talk with the examinee, transfer Its attention, reduce abdominal muscle tension; 3 various palpation techniques should be combined with different examination sites, flexible application. Inspection process The examiner attached the palm of one hand to the abdominal wall of the subject. The fingers of the other hand are flexed together and slap the contralateral abdomen with the fingertips. In order to prevent the vibration of the abdominal wall itself from passing to the opposite side, the subject (or another person) may press the ulnar side edge of the palm of the hand against the midline of the umbilicus to prevent conduction, and then slap the contralateral abdomen. If the palm of the hand attached to the abdominal wall has a liquid impact, it is a liquid wave or a liquid wave tremor. Normal people have no fluid tremors. When there is a large amount of ascites in the abdomen, there may be fluid wave tremor. Not suitable for the crowd Inappropriate people: those with mental disorders.
