Abstract
Objective Methods fi ned as being below the 3rd percentile weight for their age on a national growthchart, and having oral intubation with uncuffed ET were identifi ed and reviewed. Tracheal tubesize selections using the age-based formula (internal diameter (mm) = age in years +16 divided by4) as well as the length-based formula (the Broselow tape) were compared with the actual size ofthe ET used.Results Conclusion Chiang Mai Medical Journal 2010;49(2):49-52.The age-based prediction of ET size can be applied to most children with failure tothrive and underlying heart diseases. In contrast, the length-based formula is an inaccurate means topredict ET size in these children.Sixty children were enrolled in this study. The age-predicted ET size matched the actualsize exactly in 37 children (61.7%; 95% CI, 49%-72.9%). It underestimated the actual ET size in 10cases (16.7%) and overestimated in 13 (21.6%). The length – predicted ET size matched the actualsize exactly in 7 children (11.7%; 95% CI, 5.8%-22.2%), but it was underestimated in the remaining53 (88.3%).We conducted a retrospective study of children aged 2-8 years, who underwent cardiacsurgery at Chiang Mai University Hospital from March 1, 2008 to February 31, 2009. Children withfailure to thrive, deto assess accuracy of the age-based formula and length-based formula for predictingendotracheal tube (ET) size in children with failure to thrive, who underwent cardiac surgery.
