LOCAL and topical anesthesia are employed more often than general anesthesia for endoscopic procedures, but the search for the optimum method continues. Detailed studies of the size of the infant trachea help determine the proper size of various tubes (endotracheal, bronchoscopic, and tracheostomy) used in the care of this group of patients. Fiberoptic flexible esophagoscopy may have some advantage in enabling a more detailed examination of the lower esophagus, while the rigid tube is superior in identifying varices.
Tracheal Size in Children
In a study of 24 tracheas taken from autopsies of children, details of the patterns in length and cross-section areas revealed different growth curves.1Tracheal size in the infant was determined bronchoscopically with the head in a relatively neutral position and respiratory movements reduced to a minimum to aid in estimating optimum bronchoscopic, endotracheal, and tracheostomy tube size and design.2 In 100 cases the tracheal lengths
