Ostomy Care

Core Concepts

What an ostomy is and why it is created

An ostomy reroutes waste. In a colostomy, the more distal (closer to the rectum) the opening, the more formed the output: an ascending colostomy produces near-liquid stool, while a sigmoid colostomy can produce fairly formed stool on a more predictable schedule. In an ileostomy, the entire colon is removed or bypassed, so the effluent is liquid, continuous, and rich in digestive enzymes — exactly why it burns skin so quickly. A urostomy (typically an ileal conduit) drains urine continuously, with no voluntary control, and the urine often contains mucus because bowel tissue lines the conduit.

The healthy stoma and surrounding skin

A healthy stoma is pink to red, moist, and slightly raised, like the inside of the mouth. It has no nerve endings, so it does not hurt when touched or cleaned; slight bleeding with gentle wiping is common and expected, but active or continuous bleeding is not. In the first weeks after surgery the stoma swells, then shrinks as edema resolves, so the pouch opening must be re-measured regularly. Peristomal skin (skin around the stoma) should look like skin anywhere else — intact and dry. Skin breakdown is the most common ostomy problem and is almost always caused by effluent touching the skin, which is why a correctly fitted pouch is the first line of protection.

Pouching systems and the pouching process

Pouching systems have two parts: a skin barrier (wafer) that adheres to and protects the skin, and a pouch that collects output. One-piece systems combine them; two-piece systems let the pouch snap on and off while the wafer stays in place for days. Key technique points:

• Measure the stoma and cut the barrier opening only slightly larger than the stoma — a snug fit protects skin.
• Cleanse the skin with warm water and dry it fully; avoid harsh soaps and alcohol-based products.
• Empty the pouch before it is one-third to one-half full to prevent leakage.
• Change the full system every few days or when leakage occurs.

Output, fluids, and what to watch

Output tells you a lot. A colostomy should eventually pass gas and stool regularly (depending on location); an ileostomy produces continuous liquid output, and fluid balance is the priority because the colon's water-reabsorption job is gone. Teach the person with an ileostomy to drink plenty of fluids and recognize dehydration signs — darker, reduced urine; weakness; dry mouth. A urostomy drains continuously and the appliance must never be allowed to back up under pressure.

Diet, gas, and medication absorption

After recovery, most people eat a fairly normal diet. Teach them to chew food thoroughly and reintroduce high-fiber foods one at a time; gas-producing foods (carbonated drinks, beans, cabbage) may need trial and error, and odor is manageable with deodorizing products. For ileostomies, foods that can clog the small bowel — corn, nuts, seeds, popcorn, raw celery — are commonly limited. Medication matters too: extended-release and enteric-coated pills may pass through an ileostomy undigested, so the regimen may need review with the prescriber and pharmacist.

Complications to recognize

Learn the danger signs: a stoma that turns dark, purple, or black suggests ischemia and is an emergency; prolapse (protruding farther than usual) and retraction (sinking below skin level) need evaluation; stenosis (narrowing) can obstruct output; a parastomal hernia (bulge around the stoma) is common and may need support garments or surgery. Obstruction shows as cramping, no output, and sometimes vomiting — the person should stop eating solid food and seek care.

Patient education and psychosocial support

Discharge teaching is the heart of ostomy care: changing the pouch, measuring the stoma, knowing normal output, when to call the provider, and how to resume work, exercise, swimming, and intimacy. Many people grieve the change in their body and need honest, nonjudgmental support; connecting them with ostomy support groups and, when available, a wound, ostomy, and continence (WOCN) nurse makes a real difference. Roles vary by state and institution: pouch changes and ostomy teaching are typically within the registered nurse's scope, while other team members' responsibilities depend on local policy and supervision requirements.
