I like the multiple positioning technique to give a high enema without undue discomfort. Prepare four quarts of solution but do not be fixated on getting it all in. Begin by helping your patient to relax as she will probably be very anxious if she sees a four quart bag. I prefer to use a open top bag of two quarts capacity and keep the other two quarts in a pitcher where she will not notice it.
Begin with your patient in the Sims, (left side), position. Use a nozzle with a small balloon such as a barium enema nozzle. Lubricate the nozzle well and then lubricate her anus and rectum with copious amounts of lube. (KY or Astroglide are my favorites). Lift her right cheek and gently insert the nozzle its entire length then open the valve and with the bag no more than one foot above her rectum. Watch the level in the bag and raise the bag if flow is too slow but always question your patient about her comfort. She should feel some pressure but not cramping. She should be able to take most of two quarts in this position.
Next, stop the flow and refill the bag if necessary. Then, holding the nozzle in place ask her to slowly roll onto her back. (Alternatively, she can get into the knee-chest position. As long as she is comfortable this is an excellent position for the next stage of the enema.) With your patient comfortable open the valve and let about another quart flow into her then close the valve. She will have felt the first two quarts moving inside her as she turns and her transverse colon will be filled. If you have gotten this far without cramping you are doing very well.
Next, have her turn onto her right side. She will feel water moving and may notice gurgling as gas moves. Open the valve and let the last quart flow freely.
By using the multiple positioning technique you can get solution into the ascending colon without undue pressure. If she feels very full at some point while taking the second step, stop the flow and help her to turn onto her right side. This usually lowers the pressure and allows more solution to be administered.
Now you have a patient with a bowel full of solution. You cannot use a very irritating or stimulating solution or your patient will not be able to take it as the urge to expel will take over and she may not be able to make it to the toilet. Now, deflate any balloon and slowly and gently remove the nozzle with as little manipulation as possible. Help your patient to turn and lay on her back with her knees flexed. This should be a comfortable position. When she tells you that she needs to expel help her to the toilet without delay. She may not be able to retain without some pressure on her anus or her cheeks pressed firmly together.
Give her time to expel. The solution which has worked its way into the transverse colon and especially the ascending colon will not come out right away. When she tells you that she feels like she is done help her to clean herself and encourage her to walk around the house. She will probably walk back to the bathroom without too much delay! Expect it to take at least an hour or two for her colon to pump out all of the enema.
After she is done expelling ask her how she feels. She should feel very relaxed and have no cramping or burning. If she has burning of the anus apply Prep H cream or vitamin A& 😁 ointment.
