The success criteria of the pediatric enema model are mainly used to evaluate whether the trainees comply with clinical norms and teaching requirements during the operation process. First of all, trainees should be able to correctly complete the preparations before the operation, including verifying the identity, explaining the purpose of the operation, preparing all the enema fluid and equipment, and placing the "child patient" in an appropriate position.

Secondly, during the operation, strictly follow the principles of sterility and care. Correctly select the enema tube, apply lubricant, and gently insert it into the anus. The depth should be appropriate and excessive force should be avoided. During the perfusion process, the flow rate of the enema fluid should be stable and the temperature appropriate to avoid discomfort caused by being too fast or too cold. Trainees need to observe the changes in the model's abdomen and the liquid injection situation to ensure that the liquid can smoothly enter the intestine and reach the expected volume.

After the operation is completed, the tube should be pulled out in time, the anus should be pressed and the "child" should be assisted to maintain the position so that the enema fluid can be retained for as long as possible. Finally, it is necessary to carry out cleaning and organizing, comfort the "child patient", and record the operation situation. If the operation steps are complete, the techniques are standardized, the liquid injection is smooth and there are no obvious errors, it can be regarded as a successful operation of the pediatric enema model.
