The depth of tracheal intubation for children is different. It is mainly determined by the child's age and condition. Generally, tracheal intubation is a timely method to save the child's life and relieve the passage, but the specific depth of intubation should be distinguished according to the child's age. Therefore, it is absolutely not allowed to be blind to avoid causing greater threats to the child. Under normal conditions, the depth of oral intubation for newborns is generally around 9 centimeters, and the depth of nasal intubation is around 11 centimeters. For children around 6 months old within one year, the depth of oral intubation is around 10 centimeters, and the depth of oral intubation for two-year-old children is 12 centimeters. If the depth of nasal intubation is 17 centimeters, the depth of intubation is determined by age growth. It is important to note that for these intubation treatment issues for children, it is essential to go to a professional and formal hospital. Doctors with more experience can provide more assurance for the child's treatment and reduce more adverse injuries to the child, especially for newborns, who require sufficient experience and technical support in intubation treatment. Generally speaking, the depth of intubation can be calculated through a formula. As the child grows older, the depth of intubation varies, and the formula is: depth = age × 2 + 12. The specific depth still needs to be calculated according to the child's age.
