There are two ways to do a bowel clean out in a healthcare setting. The first one involves drinking a large amount of a special liquid within a few hours (called oral clean out). The second one involves giving liquid through a tube in your child’s nose (called a nasogastric tube).
Doing an oral clean out
The doctor can try this approach if your child is old enough to understand and follow instructions.
To start an oral clean out, a nurse will prepare a special liquid for your child to drink. Often this will be a mix of a laxative (medicine to empty the bowels) and a balanced electrolyte or rehydration drink. The doctor or nurse will pick the drink and tell you how much to give each hour. Depending on your child's age and weight, your child will need to drink 4 to 16 ounces of the liquid every hour for about 4 to 8 hours.
Doing a clean out using a nasogastric tube
If your child has trouble drinking enough of the liquid, starts to feel sick or vomit, or is too young to follow instructions, the doctor might recommend using a nasogastric (NG) tube.
To start a clean out using an NG tube, a doctor or nurse puts a small, flexible tube through your child’s nose, down the throat, and into the stomach. An I.V. line (a needle with a tube attached) may be placed in your child’s arm to give fluids or medicine during the cleanout.
When the NG tube is in place and tube placement has been verified, the nurse connects it to a drip bag. This bag is filled with a solution that has laxatives and electrolytes, such as GoLYTELY. A machine then pumps the solution directly into your child’s stomach at a steady pace.
