7.5 Ostomies

An ostomy is a surgical procedure that creates an opening (stoma) from an area inside the body to the outside of the body. In ostomies related to elimination, a stoma is an opening on the abdomen that is connected to the gastrointestinal or urinary system to allow waste (urine or feces) to be collected in a pouch. See Figure 7.5.1 for an image of a stoma. A stoma can be permanent, such as when an organ is removed, or temporary, such as when an organ requires time to heal. Ostomies are created for clients with conditions such as cancer of the bowel or bladder, inflammatory bowel diseases, or perforation of the colon.

Figure 7.5.1 Stoma

There are several different kinds of ostomies related to elimination. Common types of ostomies include the following:

  • Ileostomy: The lower end of the small intestine (ileum) is attached to a stoma to bypass the colon, rectum, and anus.
  • Colostomy: The colon is attached to a stoma to bypass the rectum and the anus.
  • Urostomy: The ureters (tubes that carry urine from the kidney to the bladder) are attached to a stoma to bypass the bladder.

Figures 7.5.2 and 7.5.3 show the anatomical locations of ileostomies and various sites of colostomies. It is important to understand the site of a client’s colostomy because the site impacts the characteristics of the waste. For example, due to the natural digestive process of the colon and absorption of water, waste from an ileostomy or a colostomy placed in the anterior ascending colon will be watery compared to waste from an ostomy placed in the descending colon.

Figure 7.5.2 Location of an ileostomy compared to colostomies
Figure 7.5.3 Colostomy types

The tissue of a stoma is very delicate. Immediately after surgery, a stoma is swollen, but it will shrink in size over several weeks. A healthy, healed stoma appears moist and dark red or pink in colour. Stomas that are swollen; dry; have malodorous discharge; or are bluish, purple, black, or pale should be reported to the provider. The skin surrounding a stoma can easily become irritated from the pouch adhesive or leakage of fluid from the stoma, so the nurse must perform interventions to prevent skin breakdown. Any identified signs of skin breakdown should be reported to the provider.

Stoma appliances are supplied as a one- or two-piece set. A two-piece set consists of an ostomy barrier (also called a wafer) and a pouch. The ostomy barrier is the part of the appliance that sticks to the skin with a hole that is fitted around the stoma. The pouch collects the waste and must be emptied regularly. It attaches to the ostomy barrier in a clicking motion to secure the two parts, similar to how a plastic storage container cover snaps to a container to create a seal. The pouching system must be completely sealed to prevent the leaking of the waste and to protect the surrounding peristomal skin. The pouch has an end with an opening where the waste is drained and is closed using a plastic clip or Velcro strip.

In a one-piece stoma appliance set, the ostomy barrier and the pouch are one piece. See Figure 7.5.4 for an image of a stoma with an ostomy barrier in place. See Figure 7.5.5 for an image of a client with an ileostomy appliance with a pouch attached. The flange is the adhesive part of the ostomy pouching system that secures it to the body.

Figure 7.5.4 Ostomy barrier
Figure 7.5.5 Ostomy pouch

Individuals with colostomies, ileostomies, and urostomies have no sensation and no control over the output of the stoma. Depending on the type of system, the ostomy appliance can last from four to seven days, but the pouch must be changed if there is leaking, odour, excessive skin exposure, or itching or burning under the skin barrier. Clients with pouches can swim and take showers with the pouching system on.

Changing an Ostomy Appliance (Flange and Pouch)

Some elements of ostomy care involve restricted activities. HCAs must have client-specific delegation from a regulated health professional to perform any restricted activities. 

Safety Considerations

  • Pouching system should be changed every 4 to 7 days, depending on the client and type of pouch. Notify supervisor if there is skin breakdown, if there are challenges with flange adhesion, or if there are other concerns related to the pouching system.
  • Clients should participate in the care of their ostomy, if able, and health care providers should promote client and family involvement.
  • Encourage the client to empty the pouch when it is one-third to one-half full of urine, flatus, or feces as they become heavy and have increased risk of spillage.
  • Ostomy product choices may be limited in acute care settings. Other choices are available in community retail settings. Encourage the client/family to explore other options.
  • Observe the centre of the flange for evidence of leaking. Waste on the peristomal skin can cause skin breakdown. Leaking flanges must be changed immediately.
  • An ostomy belt may be used to help hold the ostomy pouch in place.
  • Factors that affect the pouching system include sweating, high heat, moist or oily skin, and physical exercise.
  • Always report minor skin irritations immediately. Skin that is sore, wet, or red is difficult to seal with a flange.
  • Change ileostomy appliances prior to eating to decrease the likelihood that a bowel movement will occur during appliance change.
Table 7.5.1 Procedure: Changing an Ostomy Appliance[1]
STEP ACTION ADDITIONAL INFORMATION
1. Perform hand hygiene. This prevents the spread of microorganisms.

Figure 7.5.6 Hand hygiene
2. Gather supplies, including:

  • flange
  • ostomy bag and clip
  • scissors,
  • stoma measuring guide
  • waterproof pad
  • pen
  • adhesive remover for old flange
  • stomahesive paste or powder
  • warm wet cloth(s) and dry cloth
  • non-sterile gloves
Figure 7.5.7 Ostomy Supplies
3. Identify the client and review the procedure. Encourage the client to participate as much as possible, or observe and assist client as they complete the procedure. Proper identification complies with agency policy. Encouraging clients to participate helps them adjust to having an ostomy.
4. Create privacy. Place waterproof pad under pouch. The pad prevents the spilling of effluent on client and bed sheets.
5. Apply gloves. Remove the ostomy bag, and measure and empty contents. Place the old pouching system in a garbage bag.
Figure 7.5.8 Removing an ostomy bag
6. Remove the flange by gently pulling it toward the stoma. Support the skin with your other hand. An adhesive remover may be used. Gentle removal helps prevent skin tears. An adhesive remover may be used to decrease skin and hair stripping.

Figure 7.5.9 Removing a flange
7. Clean the stoma gently by wiping with warm water. Do not use soap. Aggressive cleaning can cause bleeding. If removing the stomahesive paste from the skin, use a dry cloth first.

Clean the stoma and peristomal skin.

Figure 7.5.10 Cleaning a stoma
8. Observe the stoma and peristomal skin. A stoma should be pink to red in colour, preferrably moist and raised above skin level.

Figure 7.5.11 Healthy stoma

Observe stoma

Skin surrounding the stoma should be intact and free from wounds, rashes, or skin breakdown. Notify your supervisor if you are concerned about the condition of the peristomal skin.

9. Measure the stoma diameter using the measuring guide (tracing template) and cut out stoma hole.

Trace diameter of the measuring guide onto the flange, and cut on the outside of the pen marking.

The opening should be 2 mm larger than the stoma size.

Keep the measurement guide with the client’s supplies for future use. Trace template.

Figure 7.5.12 Measuring stoma size

Once the size is traced onto back of flange, cut out the size to fit the stoma.

Figure 7.5.13 Cutting flange to size

Check the flange to ensure a proper fit to the stoma.

Figure 7.5.14 Fitting flange to stoma
10. Prepare skin and apply accessory products as required or according to agency policy. Peristomal skin prep.

Accessory products may include stomahesive paste, stomahesive powder, or products used to create a skin sealant to adhere pouching system to skin to prevent leaking.

Wet skin will prevent the flange from adhering to the skin.

Figure 7.5.15 Prepping peristomal skin

Apply stomahesive paste.

Figure 7.5.16 Applying stomahesive paste
11. Remove the inner backing on the flange and apply flange over stoma. Leave the border tape on. Apply pressure. Hold in place for 1 minute to warm the flange to meld to the client’s body. Then remove outer border backing and press gently to create seal. The warmth of the hand can help the appliance adhere to the skin and prevent leakage.

Remove backing from flange.

12. Apply the ostomy bag. Attach the clip to the bottom of the bag. Apply ostomy pouch. This step prevents the effluent from soiling the client or bed.

Figure 7.5.20 Applying ostomy pouch

Attach clip to bottom of bag.

Figure 7.5.21 Closing ostomy pouch
13. Hold palm of hand over ostomy pouch for 2 minutes to assist with appliance adhering to skin. Some flanges are heat activated and adhere better when warmth is applied.
14. Clean up supplies, and place the client in a comfortable position. Remove garbage from the client’s room. Removing garbage helps decrease odour.
15. Perform hand hygiene. This minimizes the transmission of microorganisms.
16. Document procedure. Follow agency policy for documentation. Document the appearance of the stoma and peristomal skin, products used, and the client’s ability to tolerate procedure and assistance with procedure.

Stool Specimen Collection

Stool samples are collected from clients to test for cancer, parasites, or occult blood (i.e., hidden blood). Follow specific instructions from the facility/agency where you are working for collecting the sample.

To collect a sample, perform the following steps:

  • Explain the procedure to the client. Instruct them to flush the toilet before defecating to remove any potential chemicals and to not place toilet paper in the toilet after defecating. Request they notify you when they have had a bowel movement.
  • Review the manufacturer’s instructions because different test kits may have different instructions.
  • Contact the laboratory with any questions.
  • Label the card with the patient’s name and medical information as per agency policy. Open the flap of the guaiac test card.
  • Apply non-sterile gloves. Use the applicator stick to apply a thin smear of the stool specimen to one of the squares of filter paper on the card. Obtain a second specimen from a different part of the stool and apply it to the second square of filter paper on the card. (Occult blood isn’t typically equally dispersed throughout the stool.)
  • Place the labelled test card in a transport bag and send it to the laboratory for analysis.
  • If you are working in an agency where nurses apply the guaiac developer solution to the card, allow the specimen to dry for 3–5 minutes. Open the reverse side of the card and apply two drops of guaiac developer solution to each square. A blue reaction will occur within 60 seconds if the test is positive. The absence of a blue colour after 60 seconds is considered a negative test.
  • Document the date and time of the test and any unusual characteristics of the stool sample.
