How to do enema correctly at home

At home enema requires strict adherence to aseptic procedures and correct steps, including preparing enema solution, selecting appropriate position, and controlling infusion speed. Enema is commonly used to relieve constipation or preoperative bowel preparation, but improper operation may lead to intestinal mucosal damage or electrolyte imbalance.

1. Prepare enema solution

Use physiological saline or warm water to prepare the enema solution, with a temperature controlled at around 37 degrees Celsius, to avoid over cooling and over heating that may irritate the intestines. Adults should not exceed 1000 milliliters per infusion, and children should reduce their dosage according to their age. A small amount of glycerol can be added to help lubricate, but it is forbidden to add drugs or irritating substances at will.

2. Choose an appropriate position

Adopt a left lateral position and bend the knee, which is conducive to the natural flow of enema along the sigmoid colon. Raise the buttocks by about 10 centimeters and use a disposable waterproof pad to protect the bed sheet. Before operation, the bladder must be emptied to maintain a relaxed state of the muscles throughout the body.

III. Control the infusion speed

Hang the enema bag at a height of 30-50 centimeters from the buttocks and control the flow rate through a regulator. There should be no resistance when the liquid enters, and if abdominal pain occurs, it should be stopped immediately. Maintain even breathing during the infusion process and avoid sudden changes in position.

Fourth, catheter insertion method

Lubricate the front end of the catheter by 5 centimeters and slowly rotate it to advance 10-15 centimeters. Do not forcefully insert when encountering resistance. You can adjust the angle or exit and try again. Elderly patients should pay special attention to gentle movements to prevent damage to the rectal mucosa.

Fifth, retention and excretion

After enema, maintain the position for 5-10 minutes before defecation. Clean enema should be repeated until the discharge is clear. Observe for any abnormalities such as bleeding or severe abdominal pain after operation, and seek medical attention promptly if discomfort occurs. The interval between two enemas should be more than 6 hours.

Home enemas should not be performed frequently, as long-term dependence may affect the spontaneous defecation function of the intestines. Daily efforts should be made to improve constipation by increasing dietary fiber and engaging in regular exercise. Patients with intestinal obstruction, gastrointestinal bleeding, or severe cardiovascular disease are prohibited from self enema. Pregnant women and children should operate under professional guidance. The enema equipment should be thoroughly disinfected before and after use to avoid cross infection. If constipation symptoms persist and do not improve, it is recommended to promptly seek medical attention from a gastroenterologist to assess the cause.
