Randomized Controlled Trial Comparative Study
Comparison of standard polyvinyl chloride tracheal tubes and straight reinforced tracheal tubes for tracheal intubation through different sizes of the Airtraq laryngoscope in anesthetized and paralyzed patients: a randomized prospective study.
The authors compared the intubation success rate of straight reinforced tracheal tubes emerging from the Airtraq laryngoscope (Prodol Meditec S.A., Vizcaya, Spain) with standard preformed polyvinyl chloride tracheal tubes in anesthetized patients. ⋯ Standard polyvinyl chloride tracheal tubes were found to be superior compared with standard and silicone straight wire-reinforced tubes for intubation through the Airtraq laryngoscope. In the latter groups, a decrease of the ratio of their OD to the width of the Airtraq guiding channel resulted in increased intubation failure.
