After brain injury, messages from the rectum to the brain
that signal the need to have a bowel movement may be interrupted or blocked.
As a result, you may not feel the urge to defecate and/or you may not have
control of the sphincter muscle that makes your bowel move. Not being able
to control the sphincter can result in an inability to have a bowel movement.
Changes in diet and activity routine, level of arousal, and cognitive (thinking)
skills, such as attention, self-awareness, and memory, can also interfere
with bowel regulation. Lack of bowel regulation can result in problems such
as diarrhea, constipation, or impaction. Impaction is severe constipation
with an inability to pass stool and can be serious if it occurs high up in
Your nurse will help you work out the best possible bowel
program for you.
The goals of the bowel program are:
to have a bowel movement at a predictable time and avoid accidents
to make the stool soft
to make a sluggish bowel work better.
The parts of the bowel program are:
Suppository every night: In the beginning, your program will probably be
as simple as a suppository or Theravac every night, which will cause the
rectum to empty of stool. As time goes on, a pattern should start to develop
and you should have bowel movements fairly regularly.
Suppository every 2nd or 3rd day: Your program will then be changed to a
suppository every other day, or, for some patients, every third day.
Choose foods high in fiber (roughage), such as fresh fruits, vegetables,
and whole grain foods.
Drink enough liquids to keep the stool soft and/or use a stool softener.
Prune juice is a great natural laxative. Fluid requirements are managed through
a feeding tube when an individual is unable to take liquids by mouth.
Avoid foods which cause constipation, or very hard stools, such as meats
and dairy products which are low in fiber or roughage.
Avoid foods which cause diarrhea, or very loose stools, such as spicy, greasy
foods, onions, etc.
Be as active as you can. The lack of activity can cause constipation.
If your program involves promoting bowel movements at a predictable time,
stick to the program developed for you to avoid constipation, impaction,
and bowel accidents
If necessary, medication will be prescribed to soften the stool and make
the sluggish bowel work better.
Learn, by experimenting, the foods and lifestyles that
let you have bowel movements at a predictable time. Once you are having regular
bowel movements, stick to the bowel program you developed. Skipping your
program can cause constipation, impaction, and bowel accidents. If something
is wrong with your program, it is usually related to diet and/or activity.
Remember to think about what you eat, drink, and do if a difficulty occurs.
When you are discharged from the hospital, you may decide
to change your program to fit your lifestyle. If you have learned the things
that work, and do not work for you, you will be able to make changes with
a minimum amount of discomfort.
The medications and stimulants used in managing your
bowel program are:
|WHAT IT DOES
Glycerine when effective; it is cheaper for long-term use.
|To set off reflexes that start movement of lower colon and rectum.
Glycerine irritates rectum mechanically and causes bowel movement.
Dulcolax takes effect when it comes into contact with the intestinal wall
and stimulates nerve endings there.
|Some patients are able to stop using suppositories and then digital
stimulation (with gloved, lubricated finger) may be all that's needed
Many people need to use Dulcolax at first, but then are able to switch to
|To soften stool (to avoid impaction or constipation)
You may not need them if your diet and fluids are adequate.
|If stool softeners are going to work, you must drink plenty of fluids.
If stool becomes too soft, you may have unscheduled bowel movement. What
to do: stop stool softener or decrease dosage for a short period. Start again
when stool is firm enough again.
|Peristaltic Stimulators and Stool Softeners
|To stimulate the normal wave-like movement of the bowel which propels
stool through the bowel.
||If you're having loose or unscheduled bowel movements, medicine will
need to be decreased or stopped.
|To increase amount of material in intestine.
|Amount prescribed is taken in a glass of water once or twice daily. Drink
plenty of liquids when taking Metamucil.
|Theravac Mini Enema
||To set off reflexes that start movement of bowel, colon, and rectum
||To administer: pinprick neck of enema bulb only. (Never cut, may tear
rectal lining); with gloved, lubricated finger, gently squeeze contents into
rectal vault-allow 20 to 30 min. for complete evacuation.
||To prevent acute symptoms if hyperreflexia is a problem.
||It may delay bowel movement; insert into rectum 5-10 minutes prior to
inserting suppository, using digital stimulation or manual removal.
Fleets enema or oil retention enema in 4 ½ oz tube.
|Use only if you are very constipated.
||1. If you make your own enema, never use more than two cups (500cc);
one cup should be enough
2. Do not use routinely; can decrease bowel tone.
Milk of Magnesia
|Use only for severe constipation or if your doctor orders.
||They upset a bowel program as they can cause much of bowel to empty;
can cause unscheduled bowel movement.
