Here is how enemas work for fecal disimpaction. A large amount of fluid (an enema recipe that is prescribed by your doctor) is inserted through the rectum. The patient retains the solution between 5-10 minutes and then has a bowel movement, eliminating the solution and part of the fecal impaction. We recommend 3 enemas per day for 3 days, followed by an abdominal radiograph to confirm that the impaction has resolved.
