Abstract: (3569 Views)
Background: Tracheal intubation is used for most pediatric patients who under general anesthesia. Selecting an appropriate size of endotracheal tube decreases the complications of intubation. In this study, the size of endotracheal tubes suggested by the standard formula of Cole is compared with the endotracheal tube sizes used for intubation of trachea.
Materials and Methods: This descriptive and analytical study was carried out on 245 patients aged 1-14 years old who were undergone general anesthesia, and were all intubated in Ali-Ibn Abitaleb and moradi hospitals of Rafsanjan. The patients were selected in simple non - randomized method and the sizes of endotracheal tubes used for intubation were compared with the sizes suggested by the Cole formula.
Results: In this survey the size of the endotracheal tubes used for the patients at different ages were smaller than the sizes suggested by the Cole’s formula (p=0.000). These differences increased with the increase of age. Endotracheal tube size in girls and boys was not significantly different. Of endotracheal tubes, 81/2% were with cuff and 18.8% uncuffed..
Conclusion: Regarding the results of this study, use of the standard Cole’s formula for selecting the appropriate size of the tube is not suitable and needs be modified. Regarding the spectrum of differences in tube sizes, we suggest the new formula age /4 +3.5 for Iranian patients aged 1-14 years old.
