What should the nurse do that is unique to a return flow enema?

Lower the solution container after instilling about 150 mL of solution.

Lowering the container of solution create a siphon effect that pulls the instilled fluid back out through the rectal tube into the solution container. The return flow promotes the evacuation of gas from the intestines. This technique is used only with a return flow enema. All rectal tube should be lubricated to facilitate entry of the tube into the anus and rectum and prevent mucosal trauma.The anal canal is 1 to 2 inches long. Inserting the rectal tube 3 to 4 inches ensures that the tip of the tube is beyond the anal Sphincter. This action is appropriate for all types of enemas. The solution container should be raised no higher than 12 inches for all enemas; this allows the solution to instill slowly. which limits discomfort and intestinal spasms.
