During ileostomy lavage, how much NS is instilled?

• A. 100-200 cc NS
• B. 30-50 cc NS
• C. 5-10 cc NS
• D. 200-400 cc NS

Answer: (B)

The main idea is to use a gentle, low-volume rinse to clear the ileostomy lumen without overloading the small bowel. Instilling a small amount of normal saline, about 30–50 mL, is enough to loosen mucus and flush the distal portion of the ileostomy without causing distention, cramping, or rapid fluid shifts. Using larger volumes would risk overdistending the ileum and increasing the chance of discomfort or electrolyte imbalance, while too little (like 5–10 mL) wouldn’t effectively cleanse. So, a gentle 30–50 mL NS instillation achieves a safe, practical lavage.
