The first thing to do is to choose the right enema solution. Generally, the enema solution needs to be warm water, at a temperature of about 37 degrees Celsius, which helps to reduce the discomfort generated during the enema. At the same time, you can choose the appropriate enema medication according to the purpose of the enema, generally choose soft soap. After the enema solution is prepared, the enema solution can be poured into a special enema device, generally the amount of enema solution does not exceed 500 ml. It is necessary to maintain a good position, usually in a lateral position, so as to facilitate the operation of the enema. After the enema operation starts, the catheter is placed in the direction of the anus for about 2cm, and then backward for some distance, then turn on the enema switch and let the enema fluid flow into the rectum. As the fluid in the rectum increases, you will feel the urge to have a bowel movement and the process of enema operation will be completed.
