Catheter is used in children's enema, which is used to pour antipyretic drugs directly into the rectum from the anus of the baby. The intestinal vascular wall can quickly absorb the antipyretic drugs to achieve the cooling effect, which can reduce the fever.
This method has not been absorbed by digestive tract and liver, and its effect is better than that of oral medicine to reduce fever. If we talk about the harm of enema, it mainly depends on the pipeline used and the operation level of nurses.
