Intestinal obstruction often leads to pain in the lower abdomen, and the intensity of abdominal pain can change. In severe cases, constant abdominal pain means that the blood supply to the intestine is blocked or the intestine to appears perforated. The symptoms are mainly abdominal pain, vomiting, abdominal distension, no stool and no anal venting, the details are as follows: 1.
2.Body temperature: normal or slightly elevated, elevated body temperature is a sign of intestinal strangulation or intestinal necrosis.
3, abdomen: attention should be paid to whether there is a surgical scar, obese patients should especially pay attention to inguinal hernia and femoral hernia, because excessive subcutaneous fat is easy to ignore, the distended intestinal canal has pressure pain when colic is accompanied by intestinal pattern or peristaltic wave, if local pressure pain with abdominal muscle tension and rebound pain is a sign of strangulated intestinal obstruction, when auscultation, attention should be paid to the change in tone of intestinal sounds, colic is accompanied by air over water sound, the intestinal canal is highly dilated can be heard “tinkling” (tinkling) metallic sound (high tone).
Second, the symptoms of intestinal obstruction 1, vomiting: the retroperistalsis of the intestinal tube after the obstruction makes the patient vomit, vomit begins to stomach contents, later intestinal contents, high small intestinal obstruction colic is not heavy, but frequent vomiting middle or distal small intestinal obstruction vomiting appears later, low small intestinal obstruction vomit is sometimes “fecal-like” is due to intestinal contents The retention of intestinal contents, the overgrowth of bacteria decompose intestinal contents.
2, abdominal pain: paroxysmal colic jejunum or upper ileal obstruction, every 3 to 5 minutes, the end of the ileum or large intestine obstruction every 6 to 9 minutes, intermittent pain relief, colic period accompanied by hyperintense intestinal sounds, intestinal sounds are high-pitched sometimes can hear the sound of gas over water, paralytic intestinal obstruction can be no abdominal pain, high small intestinal obstruction colic can not be serious, the middle or low intestinal obstruction is typically severe If the paroxysmal colic turns into continuous abdominal pain, it should be considered to have developed into strangulated intestinal obstruction.
3, abdominal distension: mostly occurs in the late stage, high small intestine obstruction is not as obvious as the low, colonic obstruction because of the presence of ileocecal valve, regurgitation obstruction rarely occurs, often closed loop, so the abdominal distension is obvious, strangulated intestinal obstruction, the abdomen is asymmetrically swollen, you can feel the expanded intestinal loops.
4, exhaustion and defecation stop: patients with intestinal obstruction generally stop defecating and exhausting from the anus, but mesenteric vascular embolism and intussusception can discharge thin stool or bloody mucus, and patients with colonic tumor diverticulum or gallstone obstruction often have black stool.
