Abstract :

BACKGROUND: Using a too big or a too small size of an endotracheal tube in pediatric patients would result in tracheal injury or insufficient ventilation. Determining the appropriate endotracheal tube size is important because using an inappropriate size can cause complications. This study was performed to predict the appropriate endotracheal tube size by measuring the transverse diameter of the epiphysis of the distal radius under the assumption that the growth rates of cartilages in the entire body are close to each other. AIM: This study was performed to predict the appropriate endotracheal tube size by measuring the transverse diameter of epiphysis of distal radius under the assumption that growth rate of cartilages in the entire body are close to each other. METHODS: Sixty children aged 3 to 10 years who required general anesthesia were intubated with an un cuffed endotracheal tube. The tube size was considered to be appropriate when leaks occurred at inspiratory peak pressures between 10 to 25 mmHg. The transverse diameters of the epiphysis were measured with an ultra–sonogram at the distal radius and the proximal phalanx of the third finger and the fifth finger. Correlations and prediction probabilities of measurements were evaluated. RESULT: The correlation coefficient between the endotracheal tube and the epiphysis of the distal radius was 0.8878 .failure rate was 10%. CONCLUSION: appropriate endotracheal tube selection by epiphyseal growth of the radius has a more close relationship and superior predictability than demographic variables.
