By that I mean, sometimes when I think I am finished expelling I am not really empty, and then some time later more is ready to come out. This could be anywhere from ten minutes to an hour later. This is particularly troubling at night if I have an enema before bed.
For a more thorough evacuation:
Use a plain water solution temperature of 100 F to 105 F.
Optionally add 30 cc of glycerin per litre of water.
Lay on your left side, left leg almost straight and right knee drawn towards your waist.
Insert the lubricated end of the enema tube.
Do not raise the bag or bucket to use gravity flow. Lay the bag on the bed or set the bucket on your nightstand and instill the enema solution using a Higginson Syringe. Do not rush. Allow no less than 15 seconds per squeeze of the bulb.
If the colon starts to spasm you will feel resistance when squeezing the Higginson syringe. Just hold the syringe until you feel the resistance ease and resume instilling the solution until the bag or bucket is empty.
Once the solution in the bag or bucket is empty do not continue to squeeze the bulb to use all the remaining solution in the tubing and Higginson syringe. You risk pumping air into the rectum which will make retention more difficult.
Remain laying on your left side as long as you feel you can, then move to the toilet to evacuate.
Use a foot stool in front of the toilet to raise your knees while setting. The seven inch high or nine inch high Squatty-Potty stool, Tushman Ottoman etc help position/align the rectum to assist evacuation. While there are naysayers, it does work in easing evacuation.
While still setting, when you think you may have completely emptied your colon, place your feet on the floor, lean forward for 15 seconds, then lean back so your mid back rests against the toilet lid. While leaning back place your hand on the lower right of your abdomen and press. Move your hand upward to the rib cage, then across the abdomen below the rib cage and upon reaching the left front then run your hand down to the left hip. Repeat two or three times.
Stand for 15 seconds then sit back down. Wait about three to five minutes.
You should be good to go.
If you use glycerin or rectal bisacodyl in the enema then expect mucous collection in the rectum. After about 30 to 60 minutes it will often provide a feeling of needing to release flatulence. Almost invariably there will be two to three ounces of fluid. An incontinence brief or pantyliner will often absorb the mucous until such time you can clean and change. Be sure to locate the pantyliner to catch the released fluid as opposed to its regular purpose.
