[Influence of endotracheal tube cuff lubrication on postoperative sore throat and hoarseness].

Abstract

In this study, VAS scores at the end of anesthesia and the next day were both significantly higher in the lubricated group than in others. Furthermore, there is no significant difference in VAS between the sprayed group and the no-intervention group. These data suggest that lidocaine jelly lubrication to the endotracheal tube reinforces the severity of sore throat. On the other hand, there was no significant difference in VAS between the sprayed group and the no-intervention group. This suggests that lidocaine sprayed to the trachea does not reduce postoperative sore throat.
