Learning objectives
On completion of this practical lesson the learner will be
able to do the following:
• Define key terms used.
• Explain constipation, its etiology, management and
nursing care.
• Enumerate diarrhoea, its causes and nursing care.
• Describe the various treatments of the colon.
• Perform practical skill: Cleansing enema.
• Perform practical skill: Retention (oil) enema.
• Perform practical skill: Application of colonic tube
(flatus tube).
• Enema - a medical manipulation, the essence
of which is the introduction of the liquid into a
direct or colon through the anus.
• Enema is a procedure of administration
different fluids in lower section of colon for
therapeutic and diagnostic purpose.
• For therapeutic purposes enemas
are used for a very long time. In
ancient Indian manuscripts are
described prominately enema.
• There are records of such
treatment and in the Egyptian
sources. Hippocrates developed
the method of cleansing enemas
from harmful juices by gastric
lavage, laxatives and cleansing
enemas.
• Especially the widespread use of
enemas in the treatment received
in 16 - 18 centuries, when
patients put sometimes up to 10
enemas in a row.
• С лечебной целью клизмы
применяются очень давно.
В древнеиндийских
рукописях описываются
промывательные клизмы.
• Имеются упоминания о
таком лечении и в
Египетских источниках.
Гиппократ разрабатывал
метод очищения клизмами
от вредных соков путем
промывания желудка,
слабительными
средствами и
очистительными
клизмами.
• особенно широкое
применение клизм в
лечении получило в 16 - 18
вв., когда больным ставили
иногда до 10 клизм
подряд.
Enemas are classified into four groups
according to their action:
• cleansing,
• carminative,
• retention,
• return-flow enemas.
CLEANSING ENEMAS
A cleansing enema is probably the most common
type of enema.
Purpose. Cleansing enemas are intended to remove feces.
Mechanism of action. This type of enema stimulates
peristalsis via irritation of the colon/rectum and by
causing intestinal distention with fluid.
They are given chiefly to (indication):
• Remove feces in instances of constipation.
• Prepare the intestine for certain diagnostic tests such as xray or visualization tests (e.g., colonoscopy)
• Prepare the patient for surgery (prevent the escape of
feces during surgery).
• There are two general types of
cleansing enemas:
the large-volume enema
the small volume enema.
• A large-volume enema is designed
to clean the colon of as much feces
as possible. In a large-volume
enema between 500 and 1000 ml of
fluid is instilled into the
rectum/colon and the patient is
asked to retain the fluid as long as
possible. This allows the fluid to
soften and loosen the feces.
The large volume of fluid also
distends the bowel, stimulating
peristalsis.
•
Большая клизма для очистки
кишечника как можно больше
фекалий. В больших по
объему клизмы между 500 и
1000 мл жидкость вводят в
прямую кишку/толстую
кишку и пациента просят как
можно дольше удерживать
жидкость. Это позволяет
жидкости для размягчать и
разрыхлять каловые массы.
Большой объем жидкости
также раздражает кишечник,
стимулируя перистальтику.
Methods used in given a large-volume
cleansing enema:
• enema set (the rectal tip,
enema bag, tubing)
• enema bag
Skill 1. CLEANSING ENEMA

6.
Wear an apron.
7.
Prepare the enema set: Attach a rectal tube to the tubing. Close the clamp of enema bag. Prepare the solution at the required temperature. Enemas administered
to adults are usually given at 105°–110°F (40.5°–43°C). Hang the enema bag with the solution on the stand. The solution should be 30–45 cm above the rectum
for an adult. Fill the enema bag with a solution. Loosen the clamp and let a small amount of fluid to run into the kidney tray. Close the clamp.
8.
Take the Vaseline with spatula. Lubricate rectal tube with Vaseline.
9.
Spread patient buttocks with thumb and forefinger of the left hand.
10. Insert the rectal tube 7 to 10 cm slowly into the rectum, directing it toward the umbilicus.
11. Open the clamp of enema bag.
12. Slowly enter the about 500 to 1000 ml of fluid in the rectum.
13. Control for patients condition. Ask the patient to breath by abdomen.
14. Clamp the tubing.
15. Gently remove the rectal tube by pulling it through 3 to 4 layers of rag pieces.
16. Offer to the patient to take the water in the intestine during 10-15 minutes.
17. Empty the intestine in bedpan or toilet pan.
18. Conduct disinfection used material. Take the gloves off and put them in the container for disinfection.
19. Wash hands.
20. Record the type of enema. The result.
• Small-volume enemas are
designed to clear the rectum
and the sigmoid colon of
fecal matter. Small volume
enemas can be delivered with
the traditional enema kit
using 50 to 200 ml of
solution.
• But most frequently smallvolume enemas are
administered using a
prepackaged disposable
enema. Prepackaged enemas
(Fleet enema) are easily
administered and available
over the counter in most drug
stores.
Cleansing enemas. Solution used:
large-volume enema:
• Hypotonic (Tap water)
• Isotonic solution
(Norman saline)
• Soapsuds (3-5 ml soap
and 1000 ml water
Small-volume enemas:
• Hypertonic solution
Retention enema.
• Retention enema introduces oil or medication
into the rectum and sigmoid colon. The liquid is
retained for a relatively long period of time,
usually 1 to 3 hours. It acts to soften the feces and
to lubricate the rectum and anal canal, thus
facilitating the passage of feces.
The effect in 3-6 hours.
• Solution used: oil (olive, cottonseed, castor,
mineral), medication. Temperature of the solution
– 37,7°C.
Skill 2. RETENTION (OIL) ENEMA

2. the first days after operation on organs of abdominal cavity
3. after childbirth
Counter-indications:
•
Bleeding of intestine
•
ulcerous processes in a colon or anus
•
rectal prolapse
•
rectal growth
•
prolapse of the rectum
•
Rectal cancer
Equipment. Sterile: colonic tube, Janet's syringe with oil solution in a volume of 50–200 milliliters, Vaseline oil, gauze napkins, tray. Unsterile: gloves, oilcloth
and diaper (or absorbent pad), apron, screen, container with disinfectant solution.
Algorithm of action:

•
Insert the colonic tube 20 to 30 cm slowly into the rectum, directing it toward the umbilicus.
•
Attach the Janet's syringe to colonic tube and enter the oil solution.
•
Disconnect the Janet's syringe from the tube.
•
Fill the Janet's syringe with air, attach to colonic tube and carefully intake the air.
•
Gently remove the colonic tube by pulling it through 3 to 4 layers of rag pieces.
•
Wipe the anus with napkin.
•
Remove the diaper and oilcloth. Take off an apron, gloves and put into container with disinfectant solution.
•
Help patient to take a comfortable position. Give him recommendation - to lie during 6- 10 hours. Therefore this procedure should be done for the night.
•
Wash hands.
•
Record the type of enema. The result.
• Medications can be administered by enema as
well. A small-volume enema can deliver a
medicated solution directly to the rectal
mucosa. This method of medication
administration is useful when the rectum is
the area to be medicated if the client is unable
to take oral medications or if rapid absorption
of the medication is required.
Carminative enema
• Carminative enema. This is given primarily
to expel flatus. The solution instilled into the
rectum releases gas, which in turn distends the
rectum and the colon, thus causing peristalsis.
60-180 ml of fluid is introduced.
• An alternative method for flatulence application of colonic tube (flatus tube).
APPLICATION OF COLONIC TUBE (flatus tube)
Purpouse: evacuation gases of intestine
Indications:
1. Meteorism (bloat) - accumulation of gases in intestine.
2. Using for staging of medicinal and oil enemas
Counter-indications:
•
Gastric and intestinal bleeding
•
Acute inflammatory and ulcerous processes in a colon or anus
•
Anal fissure
•
Rectal cancer
•

•
Record the type of enema. The result.
NOTE: The tube can be re-inserted every 3 to 4 hour, if necessary.
• Return flow enema. Return flow enema is used
Referred also as colonic irrigation, this is used to
expel flatus. This involves the alternating flow of
fluid into and out of the large intestine to
stimulate peristalsis and the expulsion of feces.
The contraindications for cleansing
enema
• Gastric and intestinal bleeding
• Acute inflammatory and ulcerous processes in a
colon or anus
• Rectal cancer
• Cracks in the anus or rectal prolapse
• The first days after operation on organs of the
digestive system
• Bleeding hemorrhoids
General instruction for Giving Enema
1. Use the appropriate size catheter or rectal tube.
2. The rectal tube needs to be atraumatic.
3. Use lubricant.
4. Follow the temperature of solution.
5. Follow the amount of the solution.
6. Keep the correct patient position.
7. Keep the height of the enema bag.
8. Follow the depth introduction of rectal tube.
9. Follow the time of retention of solution in intestines.
10. Good condition equipment.
11. Follow the flow speed of fluid.
12. Prevent air from entering into the rectum .
13. Observe the patient's condition during the procedure.
General instruction for Giving Enema
1. The appropriate size catheter or rectal tube need to be used. For giving
a cleansing enema use no. 22 French for adults, no. 12 French for an
infant and no. 14 to 18 French for the school age child.
2. The rectal tube needs to be smooth and flexible. Any tube with a sharp
or ragged edge should not be used because of the possibility of
damaging the mucus membrane of the rectum.
3. The rectal tube is lubricated with a water soluble lubricant or with
vaseline to facilitate insertion and to decrease irritation of the rectal
mucosa. Use only a small amount to prevent blockage of the tube.
4. The temperature of the solutions needs to be adjusted according to the
purpose of the enema. To give an evacuant enema, the temperature
should be between 105 and 110°F (40.5° to 43° C) for adults and 100°F
(37.7°C) for children. A retained enema should be given at the body
temperature.
5. The amount of the solution to be administered
depends upon the type of the enema and the
age and size of the person. For giving evacuant
enema u 500 to 1000 ml for adults, 250 to 500
ml for a child and 250 ml or less for an infant.
• For giving retained enema, the quantity given
at a time should not be more than 100 ml to
150 ml so that the rectum will not be distended
to cause peristaltic movement.
How can we strengthen the mechanical action of an enema?
• The mechanical action of the enema, the more significant the greater
the amount of liquid.
• With the introduction of water into the rectum it increases the
pressure. A large amount of water is an irritant to the intestinal wall.
The increasing pressure and irritating effects of water leads to
increased peristalsis. Intensive reduction of the walls of the intestine
lead to washing of their inner surface and cleaned of residue content.
6. When an enema is administered, the patient usually
assumes a left lateral position. In this position, the
position of the sigmoid colon is below the rectum, thus
facilitating instillation of the fluid. For a high cleansing
enema, the patient changes position during the
administration of the enema from left lateral to dorsal
recumbent and then to right lateral. In this way the entire
colon will be reached by fluid. For an evacuant enema the
bed should be made flat and for a retained enema the foot
end should be raised.
• If the patient is contraindicated movement, an
enema can be put in the position of the patient on
his back, placing it on the ship.
7. The height of the enema bag should
be adjusted to regulate the flow of
the solution according to the type of
the enema administered.
For cleansing enemas, the height of the
can should not be above 18 inches
(45 cm) from the anus and for
retention enemas, it should not be
above 8 inches (20 cm) the from the
anus.
The higher the container, the greater is
the force with which the solution
flows into the rectum. There inches
an increase of 0,5 lb of pressure for
every 12 inches of elevation.
8. The distance to which the tube is inserted depends upon
the age and the size of the patient. For an adult it is
normally inserted 7.5 to 10 cm (3 to 4 inches), for children
it is inserted only 2.5 to 3.75 cm (1 to 1.5 inches). If any
obstruction is encountered, it should be withdrawn and
reported.
What should be done if the water
does not go into the intestine?
• If the water does not go into the intestine can
raise a mug Esmarch above or change the
position of the tip, pulling it back to 1-2 cm;
• If water still does not enter the intestine,
remove the tip and replace it ( as it can be
hammered feces).
• If the rectum is impacted, attempt to remove
the faecal matter with a gloved finger. The
bowels should be cleaned out by a simple
enema before giving retention enema.
9. The length of time that the enema solution is retained
will depend upon the purpose of enema and the ability
of the patient to contract the external sphincter to retain
the solution. Oil retention enemas are usually retained
for 2 to 3 hours. Other cleansing enemas are normally
retained 5 to 10 minutes. To assist a baby to retain the
solution, the nurse can press the baby's buttocks
together, thus providing pressure over the anal area.
10. Make sure the whole apparatus used for the
administration of enemas is in a good working
condition.
11. Regulate the flow of fluid according to the type of
the enema: give retention enemas very slowly,
usually by Murphy drip. Before giving cleaning
enemas, regulate the flow of fluid and pinch the tube
before the tube is inserted into the rectum.
12. Prevent air from entering into the rectum:
• By removing the froth from the solution
• By expelling air from the tube
• By not letting the fluid run in completely from tube.
13. Listen to the complaints of the client and should not
ignore any discomfort however small they are.
• Tell us what you will do if the patient felt pain?
• If the patient appeared abdominal pain, you should
immediately stop the procedure and wait until the pain
goes.
• If the pain does not subside remove the tip and report to
the doctor.
• With the introduction of the tip should not be in pain. In
this case, you should remove the tip and try to enter it
in the right direction.
• With the introduction of water should not experience
sharp pain, sharp or cutting. There should be no pain in
the abdominal wall and ligaments, navel, perineum and
scrotum. When such sensations procedure should be
stopped immediately.
14. Prepacked enemas will have their own instruction
which need to be followed unless there are other
instructions from the physician.
