RESUMEN
Objective To evaluate the accuracy of nostril width method in intubation model choose in children with cerebral pal‐sy FSPR surgery .Methods Three hundred and fifty six cases of cerebral palsy FSPR surgery were selected ,the endotracheal intu‐bation were selected by nose width method and modified weight method ,and then we made a comparison between the two methods . Kappa consistency test and rank correlation analysis were both used to analyze the consistency .Results With Kappa=0 .81 ,rank correlation coefficient 0 .905 ,we could know that there was high degree of consistency between the two methods (P<0 .01) ,of which 298 cases (83 .7% ) children selected the same model intubation strengthen model in different method ,58 cases (16 .3% ) pe‐diatric intubation choice of two methods differ by one model .Conclusion Nostril width method was simple and reliable to select in‐tubation in pediatric surgery to strengthen FSPR model .
