Observational Study
Can tongue thickness measured by ultrasonography predict difficult tracheal intubation?
Increased tongue thickness is likely to be associated with difficult airways. However, no methods to evaluate tongue thickness were available. Currently, tongue thickness can be measured by ultrasonography. The present study investigated the predictive value of tongue thickness to predict difficult tracheal intubation. ⋯ ChiCTR-RCS-14004539.
