Fundamental Definitions
- Ostomy: An opening created between an internal body structure and the surface of the skin.
- Stoma: The actual opening on the exterior abdominal surface.
- Causes for Ostomy Surgery:
- Inflammatory Bowel Disorder (IBD).
- Rupture of the intestine.
- Irreversible intestinal obstruction.
- Compromised blood supply to the intestine.
- Presence of a cancerous tumor.
Understanding Ileostomies
Definition and Location
- An ileostomy is a surgical opening into the distal small intestine (the ileum).
Types of Ileostomies
- Standard or Brooke Ileostomy: A conventional ileostomy involving the removal of the colon and rectum.
- Continent Ileostomy (Abdominal Pouch): Also known as a Kock pouch or abdominal pouch.
- Ileoanal Reservoir: Also known as a J-pouch or pelvic pouch.
Ileostomy Physiology and Characteristics
- Matured Stoma: The process and healing that results in a smooth peristomal area (the skin surrounding the stoma).
- Fecal Material (Effluent): For an ileostomy, the stool is liquid and contains high levels of digestive enzymes that can be caustic to the skin.
- Appliance: Often referred to as an ostomy pouch or collection system; the user is referred to as an "ostomate."
- Karaya Gum: A material used to protect the skin and promote better adhesion of the appliance.
The Ostomy Appliance
- Disposable Appliances: Often replaced daily during bathing.
- Reusable Equipment: Long-term equipment that can be cleaned.
- Temporary Appliances: Used specifically during the immediate postoperative phase.
Preoperative Nursing Management
Surgical Management and Interventions
- Primary provider discusses the purpose, benefits, and risks of the surgery.
- Stoma Site Selection: The stoma appearance and function are explained; the site is marked on the abdomen.
- Collaborative Care: Providers include Enterostomal Therapists (ET), Enterostomal Therapy Nurses, and Wound, Ostomy, and Continence Nurses (WOCNs).
Risk Identification and Physical Preparation
- Risks of Total Colectomy: Potential for bladder dysfunction and sexual dysfunction.
- Sexual Dysfunction: Men may be advised to collect and store sperm; women may experience slightly diminished fertility.
- Bowel Cleansing: Involves dietary restrictions combined with laxatives or lavage agents.
- Antibiotic Prophylaxis: Administration of IV antibiotics to prevent infection.
- Risks of Total Colectomy: Potential for bladder dysfunction and sexual dysfunction.
Pharmacological Adustments
- Prednisone: Must be tapered and discontinued to avoid negative effects on tissue healing.
- Stress Dose Steroids: A preoperative "stress dose" of IV steroids may be administered to prevent an adrenal crisis in patients who were previously on long-term steroids.
- Immunosuppressive Agents: Discontinued to prevent negative effects on tissue healing.
- Aspirin-containing Compounds: Discontinued to minimize the risk of bleeding.
- Blood Preparation: Obtain blood samples for typing and cross-matching to replace any surgical blood loss.
Postoperative Nursing Management of Ileostomies
Surgical Postoperative Interventions
- Rectal Pack: Absorbs drainage and promotes gradual healing; typically remains in place for to days.
- Irrigations: Used to promote healing.
- Nasogastric (NG) Tube: Used for gastrointestinal decompression.
- IV Fluids: Crucial to maintain fluid, electrolyte, and nutritional balances.
- Medications: Antibiotic therapy and analgesics for pain management.
- Monitoring: Close observation of wound healing and monitoring for intestinal obstruction, which is a serious complication.
Stomal Complications
- Bleeding: Excessive blood loss from the stoma site.
- Impaired Blood Supply: Look for changes in stoma color.
- Stenosis: Narrowing of the stomal opening.
- Prolapse/Protrusion: Excessive protrusion of the ileostomy through the abdominal wall.
- Edema: Postoperative swelling that may cause obstruction or restrict stomal blood supply.
- Stomal Necrosis: Can occur if prolapse or blood supply issues are not managed promptly.
Care for Specific Ileostomy Types
Standard/Brooke Ileostomy
- Monitor specifically for anal leakage.
- Remove rectal packing in to days.
Continent Ileostomy (Kock Pouch)
- Description: An internal reservoir formed with a portion of the terminal ileum to store GI effluent; includes a nipple valve for drainage.
- Postoperative Care:
- Temporary catheter insertion.
- Perineal area pack remains for week.
- Reinforce perineal packing and check abdominal dressings for drainage.
- Connect the stomal catheter to low intermittent suction.
- Monitor the ileal catheter for obstruction (draining color and amount).
- Perform routine saline irrigations of the ileal catheter as needed.
- Maintain skin cleanliness around the stoma.
Ileoanal Reservoir (J-Pouch)
- Goal: Maintains bowel continence; typical for clients with ulcerative colitis where the anorectal sphincter is still functional.
- Benefits: Preserves innervation of male genitalia; bladder and erectile dysfunction are unlikely; however, infertility remains a risk.
- Two-Stage Procedure:
- Stage 1: Creation of a temporary ileostomy; continuous discharge of mucus from the anus and frequent, uncontrollable watery fecal discharge from the ileostomy.
- Stage 2: Performed to months later; closes the temporary ileostomy and reunites the two sections of the ileum (anastomosis). Fecal material is eventually expelled through the anus as the anal sphincter strengthens.
- Specific Nursing Actions:
- Monitor the anal area for drainage and check the presacral drainage tube in the first stage.
- Teach clients to perform perineal (Kegel-style) exercises to manage bowel incontinence.
- Post-stage 1: Teach client to use a squirt bottle for hygiene.
- Post-stage 2: Cleanse the anus with warm, soapy water and emphasize drying the area well.
Colostomy Management
Definitions and Types
- Colostomy: An opening into the large bowel (colon).
- Indications: Cancerous lesions, ulcerative inflammatory processes, multiple polyposis, or bowel injury.
- Classifications:
- Ascending Colostomy
- Transverse Colostomy
- Descending Colostomy
- Sigmoid Colostomy
Surgical Configurations
- Single-barrel: A single stoma created after a segmental resection or abdominoperineal resection (common for tumors in the lower third of the sigmoid).
- Double-barrel: Two stomas (proximal and distal). The nursing care plan must distinguish which stoma is functional and requires irrigation.
- Loop Colostomy: A loop of bowel is lifted and supported by a glass rod or plastic butterfly device.
- Opening the Loop: The bowel itself lacks pain receptors.
- Nursing Care: Protect bedding and clothing from pungent odors and liquid fecal flow when the loop is opened (often using a temporary pouch).
Duration
- Permanent: Lifelong.
- Temporary: Treats disorders like acute diverticulitis or chronic constipation.
- Reestablishment: The interval before closing a temporary colostomy and reestablishing bowel continuity may be months or longer.
Regulating Bowel Elimination
- Methods for Descending and Sigmoid Colostomies
- These types can often be regulated through regular irrigations, essentially "training" the bowel.
- Dietary and Pharmacological Aids:
- Suppositories: For stimulating movements.
- Dietary fiber: Fiber-rich foods.
- Natural Laxatives: Prune juice.
- Stool Softeners and Laxatives:
- Dulcolax: Provides gentle, dependable constipation relief; usually in tablet form with relief in to hours.
- MiraLAX: Powder form that softens stool and relieves occasional constipation/irregularity.
- Hydration: Electrolyte-balanced drinks like Gatorade (e.g., Lemon-Lime flavor) help maintain fluid balance during bowel preparation or regulation.
