The operation norms of the tracheal intubation model for children mainly revolve around simulating the real clinical operation process.

First of all, before the operation, it is necessary to check whether the model and intubation instruments are in good condition, prepare common tools such as laryngoscopes, catheters, guide wires, and balloon syringes, and keep the operating environment clean.

Secondly, trainees should select the appropriate type of tracheal tube and laryngoscope based on the anatomical characteristics of children to avoid injuries caused by improper instruments. During the operation, first place the model head in the "sniffing position", gently open the mouth, expose the glottis with a laryngoscope, and then accurately insert the catheter into the trachea under direct vision.

After intubation is completed, the catheter should be fixed immediately and ventilation should be carried out through a balloon. Observe the rise and fall of the thorax and auscultation of simulated breathing sounds to confirm the correct position. Subsequently, trainees should master the essentials of fixing the catheter and keeping the airway unobstructed, and after the operation, they should do a good job in cleaning the equipment and maintaining the model.

By strictly following the operation norms, trainees can establish a safe and standardized skill foundation in the training of tracheal intubation for children, laying a good foundation for clinical practice.
