Optimal depth of endotracheal intubation in pediatric patients

With the growing number of pediatric endotracheal intubations performed during general anesthesia, ensuring the correct placement of pediatric endotracheal tubes has become increasingly critical. Improving the accuracy of tracheal intubation and reducing complications of tracheal intubation are essential challenges faced by anesthesiologists. This review examines recent research on the optimal positioning of pediatric endotracheal tubes, focusing on the types and models of endotracheal tubes, the placement standards and positioning methods. Additionally, it explores the mechanism and impact of factors such as height, age and head and neck movement (flexion and extension) on tube positioning. This analysis aims to enhance the understanding of pediatric endotracheal intubation to improve clinical outcomes and patient safety.
