The rationale of the study is to evaluate the feasibility of conventional cuffed polyvinyl chloride (PVC) endotracheal tube for intubation through intubating laryngeal mask airway. The design was a prospective, randomized study enrolling eighty patients of either sex, ASA grade I & II, MPG grade I & II posted for various elective surgeries under general anaesthesia. Two groups of patients were randomly selected to compare the clinical performance of conventional cuffed PVC with FTST for tracheal intubation through ILMA.Continuous variables were compared between 2 groups by performing un-paired t-test. Categorical variables were compared by using Pearson’s chi-square test. For small numbers, Fisher’s exact test was applied wherever applicable. Statistical software STATA version 13.1 was used for statistical analysis. Mean time required for insertion of ILMA in group I (FTST) was comparable statistically with group II (PVC). Incidence of successful intubation in first attempt was more in FTST group as compared to PVC group but it was not statistically significant. PVC group more frequently required maneuvers for successful intubation than FTST group. However overall success rate of intubation and time required for intubation in both the groups was comparable. The laryngopharyngeal complications observed in the present study were comparable in both the groups. The present study concluded that conventionally used cuffed PVC tube can be a feasible alternative to routinely used FTST with comparable success rate, time required for insertion and laryngopharyngeal complications.
