Evaluation of tracehal tube passage difficulty for tracehal intubation - Tracehal tube pssaga difficulty for airway management

By univariate analysis, hoarseness were significantly associated with number of tracheal intubation and resistance for tracheal tube passage (P<0.001). In a multivariate logistic regression that adjusted for known or potential effects on hoarseness, the association between number of tracheal intubation and hoarseness was no longer apparent. The resistance for tracheal tube passage was the only independently associated with hoarseness (P<0.001).
