Sponsor's own description

Background: In pediatric anesthesia, selection of the appropriate endotracheal tube (ETT) size is an important task because the inappropriate one may lead to much complication. The aim of this study is to compare between the subglotic diameter and the epiphysis diameter of radius measured by ultrasonography for prediction of optimum endotracheal tube size in children. Methods: Patients aged from 1 to 6 years will be scheduled for elective surgery under general anesthesia and intubation, were enrolled in this study. Patients were randomly divided into three groups according to method of choosing the tube size. Aged group (n =49): determined the optimal endotracheal tube size according to age of the child (internal diameter \[ID\] in mm = \[age in years + 16\] /4) suggested by Cole.4 Subglottic diameter group (n =49): The subglottic transverse diameter was estimated with ultrasonography on the middle of the anterior region of the neck at the level of cricoid cartilage. Epiphyseal diameter group (n =49): the epiphyseal transverse diameter of the distal radius was estimated with ultrasonography. Patient descriptive data, size of the selected ETT, number and size of the optimum tube, number of re-intubation due to incorrect size of ETT either smaller or larger were recorded. Subglottic transverse diameter (mm) and time of intubation were measured. After intubation, pulse, respiratory rate, arterial blood saturation, capnograghy and airway pressure were recorded during surgery. Any airway complications after extubation as edema, stenosis or stridor were also recorded.
