  • contraindicated for patients who are dehydrated and young infants
  • Patients unable to tolerate large volumes of fluid benefit most from this type of enema, which is by design low volume

Q

-You add soapsuds to tap water or saline to create the effect of intestinal irritation to stimulate peristalsis
-Use only pure castile soap
-Use soapsuds enemas with caution in pregnant women and older adults because they could cause electrolyte imbalance or damage to the intestinal mucosa.
- High enemas 1213cleanse more of the colon
-After the enema is infused, ask the patient to turn from the left lateral to the dorsal recumbent, over to the right lateral position. The position change ensures that fluid reaches the large intestine.
