Enemas Definition: An enema is when a tube is inserted in the rectum and fluid is inserted in the colon. Enemas are given to relieve constipation. Occasionally enemas are used to give medical therapy. Fleets enemas are previously prepared enema solutions in plastic bottles with a tube like tip. With the patient lying on their stomach or their side, the fleets enema tip is inserted in the rectum and the bottle is squeezed and the contents goes into the colon. This usually causes enough stimulation to create a bowel movement. Standard enemas have a bag or a bucket with a tube and a rectal catheter insert. The bag or bucket is filled with water, water and soap, water and mineral oil or some other fluids. With the patient lying on their side, the rectal catheter is inserted in the rectum and the fluid is allowed to flow into the colon. This method can give much more fluid and it can fill the colon. When the patient has the feeling to defecate (have a bowel movement) then the catheter is removed and the person goes to the toilet to relieve themselves. For a complete cleansing of the bowel, one may have to use the enema kit and fill the bag 5 or more times. There is some warning in that inserting enema fluid and relieving oneselves many times can cause the body to have an electrolyte imbalance.
