Estimation of optimal nasotracheal tube depth in adult patients.
Sung-Mi JiPublished in: Journal of dental anesthesia and pain medicine (2017)
The optimal tube depth for nasotracheally intubated adult patients correlated with height and sum of the distances from nares to tragus, tragus to angle of the mandible, and angle of the mandible to sternal notch. The proposed equation would be a useful guide to determine optimal nasotracheal tube placement.
