Flexible fiberoptic intubation of the trachea is a standard technique toestablish an airway in pediatric patients who are known or suspected to bedifficult to manage by mask ventilation or by standard methods for placementof an endotracheal tube. However, flexible fiberoptic intubation in pediatrics isnot the same as in adults because the airway anatomy of children differs withage. In addition, the characteristics of the commonly used pediatric fiberscopesdiffer from those used in adults, i.e., they are smaller, have reduced fields ofvision, have different ranges of tip angulation, and have an insertion cord that isthinner and more flexible.
