Constipation caused by dry stools or fecal impaction can be relieved by applying an enema. Enemas can be applied with corkscrew or glycerin enemas, or with water or soapy water. When applying corkscrew or glycerin enema, a portion of the glycerin should first be applied to the head end of the corkscrew or glycerin enema pessary, and then inserted into the rectum after lubrication, which can prevent damage to the mucous membrane of the rectum and cause bleeding.

After the enema in the intestinal tract to stay 2 minutes before pulling out, can play a role in loosening the role of dry knot fecal matter, to promote the rapid discharge of stool.
