Colostomy Care
Key Points
- Approximately 500,000 individuals in the United States have an ostomy; it can be permanent or temporary.
- Preoperative ostomy-site marking and education with a certified wound/ostomy clinician improve postoperative self-management readiness.
- Healthy stoma: moist, beefy pink or red; dusky/purple/black indicates compromised blood supply — report immediately.
- Pouch emptied when one-third to one-half full; pouch and wafer changed every 3–5 days.
- Many pouching systems can remain in place about 4-7 days if seal and skin integrity remain stable.
- Output consistency depends on location: ascending colon (watery) → descending/sigmoid (more formed).
- Psychosocial impact is significant — nurses must not display disgust; referral to wound/ostomy nurse specialist is key.
Pathophysiology
An ostomy creates a stoma from internal structures to the abdominal surface for waste diversion. In elimination care, diversion may involve bowel output (ileostomy/colostomy) or urine output (urostomy). Indications include bowel or bladder cancer, inflammatory bowel disease, trauma, and bowel perforation. Patients have no sensation or voluntary control over stoma output.
Output by Ostomy Location
| Ostomy Type/Location | Output Characteristics |
|---|---|
| Ileostomy | Liquid/watery; high output; risk for fluid/electrolyte loss |
| Ascending colostomy | Watery (minimal water absorbed) |
| Transverse colostomy | Semi-liquid to semi-formed |
| Descending/sigmoid colostomy | More formed/solid (most water absorbed) |
| Urostomy | Continuous urine output into pouch; no voluntary urinary control |
Continent Diversion Variants
- Continent ileostomy: Internal abdominal pouch with catheter drainage through stoma, often around three times daily.
- Ileoanal pouch pathway: Surgical pouch connected to anus; continence preserved, but frequent liquid stools can occur (including nocturnal episodes).
Nursing Assessment
NCLEX Focus
Stoma color assessment is a high-priority skill. A beefy red stoma is normal. Report bluish, purple, or black discoloration immediately (vascular compromise). Assess peristomal skin at every pouch change.
Stoma Assessment
| Finding | Interpretation |
|---|---|
| Pink/red, moist | Normal — adequate blood supply |
| Swollen (first few days post-op) | Normal — edema subsides over weeks |
| Bluish, purple, or black | Compromised blood supply → report immediately |
| Pale or dry | Possible dehydration or vascular compromise |
| Malodorous discharge | Possible infection or necrosis |
- Stoma should begin producing output within 2–3 days postoperatively
- Frequent assessment and bowel sound auscultation is critical in the first 2–4 days
Complications to Monitor
- Stomal gangrene or retraction
- Colostomy prolapse
- Peristomal hernia
- Surgical site infection
- Atelectasis and pneumonia (post-abdominal surgery)
Nursing Interventions
Preoperative Preparation
- Coordinate preoperative ostomy-site marking and education with a certified wound/ostomy nurse and surgical team.
- Explain planned stoma location rationale, pouching basics, and realistic postoperative adaptation expectations.
- Encourage family/caregiver participation in teaching sessions to strengthen early home support.
Pouching System Management
- One-piece system: skin barrier and pouch are combined
- Two-piece system: skin barrier (wafer) snaps onto the pouch separately; preferred for easier appliance changes
- Measure stoma at each appliance change (stoma shrinks over weeks after surgery); cut wafer opening to fit closely without impinging on the stoma (commonly about 2 mm larger than stoma diameter in many fitting workflows)
- Empty when one-third to one-half full to prevent leakage and skin breakdown
- Change wafer/pouch every 3–5 days, or immediately if leaking, odor, itching, or burning
- Depending on product/system and wear conditions, appliance wear time may extend to about 4-7 days when seal and skin integrity remain intact.
- For two-piece pouches with gas buildup, teach controlled pouch “burping” technique to vent gas safely and reduce ballooning discomfort.
Peristomal Skin Care
- Clean stoma and surrounding skin with warm water and mild soap (no alcohol-based products)
- Apply skin barrier products (creams, powders, protective sheets) to prevent stool irritation
- Ensure complete seal of pouching system
- Report any peristomal skin breakdown to the provider
Patient Education
- Adequate fluid intake is essential (especially with ileostomy — higher fluid losses)
- Foods to reduce gas: avoid cabbage, broccoli, beans, carbonated beverages
- Foods to reduce odor: avoid fish, eggs, onions
- Patients can shower and swim with the pouching system on
- Notify provider if: stoma changes color, swells, retracts, or develops malodorous discharge
- Colostomy irrigation (descending/sigmoid only): once daily or every other day, same time each day; allows fewer pouch changes
- Irrigation sessions can take about 1 hour and must follow consistent timing for patterning benefit.
- Avoid irrigation when contraindications are present (for example stoma prolapse/irregular function, active chemo or pelvic-abdominal radiation, or medication-related high-diarrhea risk).
Body Image and Psychosocial Support
- Recognize that ostomy profoundly affects body image, self-esteem, and intimacy
- Expect life-stage variation in functional impact; younger adults may report greater role-function disruption and need intensified coping support.
- Screen practical self-management barriers (for example arthritis, vision change, Parkinson disease, post-stroke coordination limits) and adapt teaching/support plan.
- Do not display disgust (verbal or nonverbal) at stoma appearance or odor during care
- Encourage patient and family involvement in care demonstrations before discharge
- Refer to wound, ostomy, and continence (WOC) nurse specialist, social worker, and support groups
- Patient must demonstrate independent pouch emptying before discharge
- Coordinate interdisciplinary recovery support (PT/OT, nutrition, case management, psychosocial services, WOC follow-up) for safe transition.
Discharge Readiness
Patient must demonstrate independent pouch emptying before discharge. Provide 2–3 days of supplies. Ensure follow-up with WOC nurse is scheduled.
Persistent Diarrhea Risk
Ongoing high-output diarrhea can lead to fluid-electrolyte imbalance; escalate early and evaluate for infectious contributors when clinically indicated.

Self-Check
- A patient’s stoma appears purple and dusky 2 days after colostomy surgery. What is the nursing action?
- When should the nurse empty an ostomy pouch, and how often should the pouch and wafer be changed?
- What should the nurse teach a patient about diet after a colostomy?
