Enema and infusion are two different treatments and there is no way to directly compare “which treatment is more effective”. Doctors will choose the appropriate treatment based on the patient’s condition and physical state when selecting medication, and it is recommended that you follow your doctor’s instructions. An enema is a catheter that is inserted through the anus into the rectum or colon and filled with medication. It is usually used for constipation and rectal administration of medication. Enema therapy is effective in treating constipation by stimulating peristalsis, softening and removing feces. Rectal administration of drugs is by retaining the enema, or suppository, cream insertion, etc., the drug is inserted into the patient’s anus, and absorbed into the body circulation through the rectal mucosa, so as to achieve the therapeutic purpose. Enemas generally have no effect on the body, but prolonged and repeated rectal administration of drugs may lead to intestinal mucosal damage and intestinal flora imbalance. Infusion refers to the method of introducing large amounts of sterile fluids, electrolytes, and medications into the body from a vein through a puncture. Infusions allow the body to quickly replace lost fluids or blood and continue to maintain the constant concentrations needed for efficacy. However, allergic reactions, phlebitis, febrile reactions, and acute pulmonary edema may occur with infusions. If children need enema and infusion treatment, it is recommended to go to a formal medical institution, where the doctor will make judgment and choose the appropriate treatment to achieve better therapeutic effect. In addition, formal operation can reduce the occurrence of adverse reactions and injury.
