abdominal wall tension

Abdominal wall tension refers to the degree of tension in the abdominal muscles when palpating the abdomen. It is determined according to the abdominal muscle resistance. Normal people have a certain tension on the abdominal wall, but the touch is soft and easy to collapse. The abdominal wall is soft. Some people, especially children, are amused by being unaccustomed to touching or tickling, causing abdominal muscles to become autonomous, called muscle strengthening. It can disappear after proper induction or diversion of attention, which is normal. Some pathological conditions can increase, decrease or disappear the total abdominal or local tension. This check can help determine the corresponding symptoms. Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: not fasting Tips: Pay attention to diet and rest before checking. Normal value Abdominal wall tension is normal (soft). The abdomen has some elasticity when pressed, but there is no muscle tension or resistance, and it is not full. Clinical significance Abnormal result 1. Increased abdominal wall tension. (1) The increase in total abdominal tension is as follows: 1) Fullness of the abdomen. At the time of palpation, the abdominal tension is increased, but there is no tendon and no tenderness. See the increase in abdominal contents such as flatulence or artificial pneumoperitoneum, a large number of ascites in the abdominal cavity. 2) Plate-shaped abdomen is seen in acute diffuse peritonitis caused by acute gastrointestinal perforation or organ rupture, caused by abdominal muscle spasm caused by peritoneal irritation. 3) The facial sensation is more common in tuberculous peritonitis, which is due to the slow development of tuberculous inflammation, slower peritoneal stimulation, and thickening of the peritoneum and adhesion of the intestine and mesentery. This sign can also be seen in cancerous peritonitis. (2) Increased local tension in the abdominal wall. Upper abdominal or left upper abdominal muscle tension is common in acute pancreatitis; right upper abdomen is common in acute cholecystitis; right lower abdominal muscle tension is common in acute appendix, but can also be seen in gastrointestinal perforation, gastrointestinal content on the right side of mesenteric perforation Flow to the right lower abdomen, causing muscle tension and tenderness in the part. In addition, in the elderly, frail, abdominal muscle dysplasia, a large number of ascites or obesity, although there is inflammation in the peritoneum, but the abdominal wall tension may not be obvious. Inflammation of the pelvic organs does not cause significant abdominal wall tension. 2. Abdominal wall tension is reduced: when the abdominal wall is pressed, the abdominal wall is weak and weak, and most of the abdominal muscle tension is reduced or disappeared. (1) Reduced total abdominal tension: seen in myasthenia gravis, chronic wasting disease, severe hypokalemia or a large amount of ascites. Can also be seen in the elderly or women who are thin. (2) local tension reduction: the abdominal wall is partially weak and weak, less common. Often caused by abdominal muscle spasm or defects. The former is seen in polio or peripheral nerve injury, the latter is seen in the separation of the orbital rectus muscle. People who need to be examined: people with uncomfortable abdominal and people undergoing routine physical examination. Positive results may be diseases: acute pancreatitis, acute gastroenteritis considerations Requirements for inspection: 1 The patient is lying on his back, his legs are bent, and the examiner is standing on the right side of the patient. 2 slow abdominal breathing. 3 From shallow to deep, from the left lower abdomen, counterclockwise, check the palpation method from the painless to painful part and the organ examination. Inspection process Shallow palpation: abdominal wall depression about 1CM, used to check abdominal wall tension, abdominal wall tenderness, lump and so on. Deep palpation: at least 2 cm of abdominal wall depression for examination of abdominal visceral conditions; examination of tenderness, rebound tenderness and intra-abdominal mass. a, deep sliding palpation: check the abdominal visceral, intra-abdominal mass; b, deep pressure palpation: check tenderness, rebound pain; c, palpation of both hands: check the abdominal internal organs such as liver, spleen and kidney, intra-abdominal mass; d. Impact palpation: Check the abdominal internal organs when used in a large amount of ascites. Not suitable for the crowd Inappropriate people: those who want to have a child; severe organic diseases such as cardiovascular disease and blood test indicators are not normal; those with abnormal mental disorders; those with scars; the original transverse surgical incision on the abdominal wall affects the distal blood of the abdominal wall flap Carrier. Adverse reactions and risks Nothing.
