Reduced anal venting may be caused by some conditions such as bloating and stopping venting because the peristaltic function of the stomach and intestines is weakened or even disappears. In such a case, we can take the following ways: first, try to promote the peristaltic function of the intestine, such as patients can go down and walk more, rub the abdomen with their hands to promote the peristaltic function of the intestine; second, we can use the method of anal canal exhaust, the anal canal should not be kept in the intestine for more than 20 minutes, which can stimulate the peristaltic movement of the patient’s rectum and sigmoid colon and restore the anal canal exhaust, but we must pay attention to the time of inserting the anal canal To be gentle; third, we can use a long-handled glycerin enema, which is also similar to the anal tube exhaust, these can promote the anal tube exhaust. If the patient does not have obvious obstruction, but only appear intestinal peristaltic function is weakened, we can also add drugs to promote intestinal peristalsis, such as Mosapride or Itopride can also restore the function of the anal vent, provided that there must not be intestinal obstruction, the above are some of the common methods to promote anal venting.
