, tube. Although this practice is not as common as it once was, some patients
irrigate left-sided colostomies to regulate colon emptying
 Other patients don’t want to spend additional 60-90 minutes in bathroom
everyday  empty pouch as necessary
 Only colostomies can be irrigated; never use an enema set to irrigate a
colostomyuse special cone-tipped irrigator to prevent bowel penetration &
backflow for irrigating solution
 Before irrigating stoma  patient sits on toilet & places irrigating sleeve over
stoma  extends into toilet bowl
 Healthcare provider order amount & type of irrigation solution
 Adults=ranges from 500-700mL of tap water; patient instills solution slowly
through lubricated cone tip
 Irrigation takes 5-10 minutes; patient removes cone tip & waits 30-45 minutes for
solution & feces to drain out of irrigation sleeve  once drainage stops, patient
applies a stoma cap or a pouch.
How to take care of stoma/colostomy:
 Patient needs to use meticulous skin care to prevent liquid stool from irritating the
skin around the stoma.
 Changing and emptying- change with 1/3 to ½ full (33%-50% full), check it
frequently if gases needs to be released
Types of ostomies (Temporary or permanent and types of stools to expect)
**There are three types of colostomy construction: loop, end, and double-barrel***
 Loop Colostomy- TEMPORARY
o Performed in a medical emergency, removed in 7-10 days (the rod)
o A temporary large stoma constructed in transverse colon
o Surgeon pulls loop of bowel onto the abdomen
o External supporting device (plastic rod, bridge, and rubber catheter) is
temporarily placed under the bowel loop to keep it from slipping back
o Surgeon then opens the bowel and sutures it to the skin of the abdomen
o Loop ostomy has TWO openings through ONE stoma
 Proximal end drains stool

,  Distal portion  drains mucus
 Double-barrel Colostomy- TEMPORARY
o Surgeon divides intestine and brings both proximal & distal ends through
abdominal incision to abdominal surface when creating a double-barrel
colostomy; two openings (one side is stool; other side is mucous)
o Small incision made in proximal stoma for fecal drainage, distal stoma
leads to inactive intestine is left intact
o When intestinal injury has healed  colostomy is reversed
 End Colostomy- PERMANENT or TEMPORARY
o One stoma formed from proximal end of bowel, with distal portion of GI
tract either removed or sewn closed
o Results of surgical treatment of colorectal cancer  return usually
removed
o Patients with diverticulitis who are treated surgically often have a
temporary end stoma with a Hartmann’s pouch
Normal Characteristics of ostomies:
 Deep reddish pink
 Moist
 No areas of impaired circulation or necrosis
Normal Characteristic of ileostomies:
 Red, moist

, What is a stoma?
 Mouth-like opening, an incised opening that is kept open for drainage or other
purposes, such as the opening in the abdominal.
 A surgically made artificial opening in the abdominal wall to eliminate wastes
What is a healthy stoma?
 Deep reddish pink; beefy red (like a fresh piece of meat)
 Moist
 No areas of necrosis  impaired circulation
 No signs of infection
 No skin breakdown
 Notify healthcare provider if stoma is blue, brown, or black  indicates
circulation problems to stoma
 Pain is slowed peristalsis & stress; pain meds require stool softener
Pouching ostomies and ileostomies:
 Ostomy requires pouch to collect fecal material
 An effective pouching system protects skin, contains fecal material, and remains
odor-free, comfortable, & inconspicuous.
 A person wearing a pouch needs to feel secure enough to participate in any
activity
 To ensure that the pouch fits well/meets patient’s needs, consider location of
ostomy, type &size of stoma, type & amount of ostomy drainage, size & contour
of abdomen, condition of skin around stoma, physical activities of patient,
patient’s personal preference, age & dexterity, cost of equipment.
 Some pouching systems are attached to patient’s skin from adhesive surface of
product; other pouching systems are non-adhesive
 Pouches come in one & two piece systems that are disposable or reusable
 Some pouches have opening precut by manufacturer, others require stoma
opening to be cute to patient’s specific stoma size.
One Piece Pouch System:
 Wafer skin barriers are permanently attached to the ostomy pouch
