Randomized Controlled Trial Multicenter Study
The Flex-Tip™ tracheal tube does not reduce the incidence of postoperative sore throat: a randomized controlled trial.
Sore throat after tracheal intubation is common with an incidence of 30-70%. The Parker Flex-Tip™ endotracheal tube (ETT) is designed to reduce trauma during ETT placement. This randomized single-blinded trial was designed to assess whether using the Flex-Tip ETT would reduce the incidence of postoperative sore throat and/or vocal change. ⋯ In this study involving experienced clinicians, no significant difference was observed in the incidence of postoperative sore throat or vocal change between the Flex-Tip ETT and the standard Mallinckrodt Hi-Lo cuffed ETT. This trial was registered at www.clinicaltrials.gov , NCT01095861.
