Background and Aims: Higher success rate of intubation is observed with the reverse orientation of polyvinyl chloride (PVC) tracheal tube while intubating through laryngeal mask airway (LMA) Fastrach™. It is not clear whether the same is true during intubation through LMA CTrach™ visualizing the process of intubation. The primary aim of this study was to compare the influence of the PVC tracheal tube orientation on the success rate of intubation while intubating through LMA CTrach™. Material and Methods: One-hundred and fifty patients belonging to American Society of Anesthesiologists status I–II, undergoing elective surgery under general anesthesia were randomized to either group normal orientation or group reverse orientation. A maximum of 3 intubation attempts within a span of 3 min was allowed in each group before the change over to the other group. If intubation failed with the other orientation of the tube also, then intubation through LMA CTrach™ was abandoned and intubation done by direct laryngoscopy. The success of intubation, time, maneuvers, postoperative sore throat, and hoarseness were recorded. Results: Tracheal intubation through LMA CTrach™ with PVC tube was successful in 94.5% of patients in group normal orientation and in 98.6% of patients in group reverse orientation. The first attempt success rate was 75.3% and 86.3% in group normal and group reverse orientation, respectively. The incidence of a sore throat was higher in the group normal orientation than in the reverse orientation (31.8% and 26.5%, respectively). Conclusions: Overall success rate of intubation was comparable between the two groups. Though statistically insignificant, the first attempt success rate was higher in group reverse orientation.
