OPTIMAL ENDOTRACHEAL TUBE SIZES FOR INFANTS AND CHILDREN

Abstract

This survey was made of endotracheal tube sizes in 1347 cases of infants and children under general anesthesia from January 1964 to July 1967 in Showa University Hospital.
The endotracheal tubes employed here were of the portex and marked in French sizes.
It was seen that used endotracheal sizes were influenced by age, body weight and height rather than by sex, muscle relaxants (SCC) and intubating approaches.
The guide table of the optimal endotracheal tube sizes in pediatric anesthesia was offered.
The authors were impressed that there was a considerable spread of the tube sizes particularly in 3 to 5 years old groups. Three tubes of different sizes prepared for intubation were occasionally not enough and more different size of tubes were required.
