Cessation of venting is a symptom of anal cessation of venting due to intestinal obstruction and other causes. Adhesions and adhesion zone compression Adhesions can cause symptoms of obstruction due to intestinal folding and twisting. It is the most common cause of intestinal obstruction in adults, but a few cases can be without a history of abdominal surgery and inflammation. Clinical examination of cessation of exhaustion due to intestinal obstruction: 1. Adhesive intestinal obstruction (1) Previous history of chronic obstructive symptoms and multiple recurrent acute attacks. (2) Most patients have a history of abdominal surgery, trauma, bleeding, foreign body or inflammatory disease. (3) Clinical symptoms are paroxysmal abdominal pain with nausea, vomiting, abdominal distention and cessation of defecation. Physical examination: (1) systemic condition: there are no obvious changes in the early stage of obstruction, and signs of fluid loss may appear in the late stage. When strangulation occurs, systemic toxic symptoms and shock may appear. (2) Abdominal examination should pay attention to the following conditions: ① abdominal wall incision scar can be seen if there is a history of abdominal surgery; ② the patient can have abdominal distension, and the distension is mostly asymmetric; ③ most of the intestinal pattern and peristaltic waves can be seen; ④ abdominal pressure pain is not obvious in the early stage, but obvious pressure pain can appear with the development of the disease; ⑤ if the obstructed intestinal loop is fixed, a painful mass can be found; ⑥ there can be peritoneal irritation signs or mobile turbid sounds if there is an increase in abdominal fluid or intestinal strangulation; ⑦ Before the development of intestinal obstruction to intestinal strangulation and intestinal paralysis, the intestinal sounds are hyperactive, and gas-over-water sound or metallic sound can be heard. 2, strangulated intestinal obstruction (1) abdominal pain is continuous severe abdominal pain, frequent paroxysmal intensification, without complete rest interval, vomiting can not make abdominal pain and distension relief. (2) Vomiting appears early and more frequently. (3) Systemic changes appear early, such as increased pulse rate, increased body temperature, increased white blood cell count, or a tendency to go into shock early. (4) Abdominal distension: low-level small bowel obstruction is obvious, and closed-loop small bowel obstruction is asymmetric abdominal distension, isolated distended bowel loops can be palpated, and no defecation. (5) Continuous observation: elevated body temperature, increased pulse rate, decreased blood pressure, impaired consciousness and other signs of infectious shock can be found, and bowel sounds change from hyperactive to attenuated. (6) Obvious signs of peritoneal irritation. (7) Vomit is bloody or anal discharge of bloody fluid. (8) The abdominal puncture is bloody fluid.
