Ostomies

• An ostomy is a surgically created opening to the bowel or other structure, allowing for the diversion of waste.
• Common types include ileostomy (opening to the ileum) and colostomy (opening to the colon).
• The stoma is the external part of the ostomy where materials exit the body, requiring specific care and management.
• Ileostomies are typically placed before the terminal ileum, affecting nutrient absorption, particularly vitamin B12.
• Colostomies can be located in various parts of the colon, influencing the consistency of stool and care requirements.

Nutritional Considerations for Ostomy Patients

• Patients with ileostomies are at higher risk for fluid and electrolyte imbalances due to reduced colon length.
• Clients with ileostomies should consume 8 to 10 glasses of fluid daily to maintain hydration and prevent kidney stones.
• A liberal salt intake may be necessary to replenish sodium lost through the stoma.
• Vitamin B12 deficiency can occur due to the removal of the terminal ileum, necessitating supplementation through injections or nasal sprays.

Nursing Guidelines for Ostomy Care

• Preventing skin breakdown is crucial; enzymes in stool can cause excoriation.
• Clean the stoma and surrounding skin with mild soap and water, patting dry to maintain skin integrity.
• Barrier substances like karaya can be applied to protect the skin around the stoma.
• Consult an enterostomal therapist for specialized care and advice on skin management.

Securing and Managing Ostomy Appliances

• Ostomy appliances consist of a pouch for stool collection and a faceplate that adheres to the abdomen.

• The stoma protrudes through an opening in the appliance, which must be securely fastened to prevent leaks.

• Pouches should be emptied when they are one-third to one-half full to avoid excessive weight pulling on the faceplate.

• The faceplate typically remains in place for 3 to 5 days unless there are issues with adhesion or skin irritation.

Draining a Continent Ileostomy

• A continent ileostomy allows for controlled drainage of stool without an external appliance.
• Clients must drain the reservoir every 4 to 6 hours, using a catheter inserted into the stoma.
• Proper technique includes inserting a lubricated catheter and allowing stool to flow into a container.
• If the catheter becomes blocked, techniques such as bearing down or rotating the catheter may help.

Irrigating a Colostomy

• Colostomy irrigation is similar to administering an enema, used to promote bowel elimination.
• The procedure involves instilling fluid through the stoma to help regulate bowel movements.
• Clients with sigmoid colostomies may not need to wear an appliance due to the predictability of bowel elimination after irrigation.
• Regular assessment of bowel sounds and abdominal palpation is essential to monitor the effectiveness of irrigation.
