Thus, a salt water solution can be used when a longer period of retention is desired, such as to soften an impaction.Ĭastile soap is commonly added because its irritation of the colon's lining increases the urgency to defecate. Like plain water, it simply functions mechanically to expand the colon, but having a neutral concentration gradient, it neither draws electrolytes from the body, as happens with plain water, nor draws water into the colon, as occurs with phosphates.
Normal saline is least irritating to the colon. Plain water can be used, simply functioning mechanically to expand the colon, thus prompting evacuation. įor relieving occasional constipation, a large volume enema may be used in a home setting, although for recurring or severe cases of constipation medical care may be required. Soapsuds enema is a frequently used synonym for a large volume enema (although soap is not necessary for effectivity). The colon dilates and expands when a large volume of liquid is injected into it, and the colon reacts to that sudden expansion with general contractions, peristalsis, propelling its contents toward the rectum. Soapsuds enemas, one in an enema bucket with a nozzle typical for a cleansing enema, and another in an enema bag with a nozzle typical for a contrast enemaįor emptying the entire colon as much as feasible deeper and higher enemas are utilized to reach large sections of the colon. or, as some nursing textbooks recommend, for five to fifteen minutes or as long as possible. In order for the enema to be effective the patient should retain the solution for five to ten minutes, as tolerated. An enema's efficacy depends on several factors including the volume injected and the temperature and the contents of the infusion. Such enemas' mechanism consists of the volume of the liquid causing rapid expansion of the intestinal tract in conjunction with, in the case of certain solutions, irritation of the intestinal mucosa which stimulates peristalsis and lubricates the stool to encourage a bowel movement.
However, a low enema is generally useful only for stool in the rectum, not in the intestinal tract. Ī large volume of enema can be given to cleanse as much of the colon as possible of feces. When oral laxatives are not indicated or are not sufficiently effective, enemas may be a sensible and necessary measure. The principal medical usages of enemas are:īowel cleansing Acute treatments Īs bowel stimulants, enemas are employed for the same purposes as orally administered laxatives: To relieve constipation To treat fecal impaction To empty the colon prior to a medical procedure such as a colonoscopy.

The word enema can also refer to the liquid injected, as well as to a device for administering such an injection. An enema, also known as a clyster, is an injection of fluid into the lower bowel by way of the rectum.
