When rectal washouts are given to Hirshsprung’s disease, the following fluid is used –
**Core Concept**
Rectal washouts in Hirschsprung's disease aim to remove fecal matter from the colon, reducing the risk of enterocolitis. The fluid used for rectal washouts should be hypertonic to prevent fluid absorption and maintain colonic distension.
**Why the Correct Answer is Right**
The correct fluid used for rectal washouts in Hirschsprung's disease is a hypertonic solution of **sodium phosphate**. This hypertonic solution helps to maintain colonic distension, prevents fluid absorption, and reduces the risk of enterocolitis. The sodium phosphate solution also helps to stimulate bowel movements and improve colonic motility.
**Why Each Wrong Option is Incorrect**
* **Option A:** Normal saline is isotonic and may not provide the desired effect of colonic distension and stimulation of bowel movements.
* **Option B:** Water is hypotonic and may lead to fluid absorption, worsening the condition.
* **Option C:** Glycerin suppositories may help stimulate bowel movements but are not a suitable substitute for rectal washouts in Hirschsprung's disease.
**Clinical Pearl / High-Yield Fact**
Remember that hypertonic solutions like sodium phosphate are used for rectal washouts in Hirschsprung's disease to maintain colonic distension and stimulate bowel movements. This is a key differentiator from other conditions where normal saline or water may be used.
**Correct Answer:** C. Glycerin suppositories
