Direct laryngoscopy is well proven and most commonly used technique of orotracheal intubation. Lighted stylet device is also an established technique of orotracheal intubation. Talwalkars fibrelite stylet is a type of lighted stylet deviced for orotracheal intubation. This study compares the clinical efficacy of TFS versus direct laryngoscopic technique for orotracheal intubation. Materials & Methods:Hundred patients were randomized to undergo tracheal intubation with either the Talwalkar fibrelite stylet (TFS group, n = 50) or the direct laryngoscope (LS group, n=50). Intubation was attempted with the assigned airway device. The data collected included the rate of successful endotracheal intubation, the number of attempts required, the duration of the intubation, as well as adverse effects. Statistical Analysis:The statistical analysis of the study was carried out by using ANOVA application, Chi square test, (Pearson Chai square test) wherever applicable. Results: In laryngoscopy group 45(95%) intubations were successful in first attempt, while 5(10%) required second attempt. In TFS group 30(60%) intubations were successful in first attempt and 20 (40%) required second attempt. The duration of successful intubation for the first tracheal intubation attempt was comparable in both groups. All intubations were completed successfully within two intubation attempt. Conclusions: As compared to conventional direct laryngoscopy, TFS is associated with fewer complications and correct positioning of endotracheal tube, hence it can be safe & effective device of intubation.
